The Schöningen open pit mine is a special place: As if under a microscope, the past and the future are revealed here, from the Paleolithic era to the inner-German border to HPC’s solutions for post-mining landscapes.

Previously used sections of land conceal the risk of contamination and liabilities. We take this into account with land transactions and investment projects. Important factors are Environmental Due Diligence (EDD) and Environmental Site Assessments (ESA) Phase I/II. We will estimate your investment risks and investment constraints.

Hazardous building substances according to the Ordinance on Hazardous Substances are probably found in every building constructed in the twentieth century. Unknown hazardous substances can have a lasting effect and become a health hazard for the user due to their emission potential. Air in a room can be contaminated with formaldehyde. Unqualified handling of hazardous substances during demolition or renovation can lead to the release of asbestos fibres. Unknown hazardous building materials can lead to accidents and recourse claims. We want to protect you against such high consequential costs.

Hazardous building waste resulting from demolition or disasters is a hazard and an unacceptable risk for users and third parties. They drive up costs and delay deadlines. There is a need for remediation here. We will perform an interdisciplinary investigation of the design requirements preceding demolition. Structural connections with neighbouring buildings, shared walls, the need to secure neighbouring buildings by underpinning. We will support you in recognising and eliminating dangers from the outset.

Hazardous building substances according to the definition of the Ordinance on Hazardous Substances are probably found in every building constructed in the twentieth century. This does not necessarily require dismantling. For existing substances such as non-friable asbestos products and carcinogenic mineral fibres, so-called old artificial mineral fibres (AMF), provisions can be made to protect the existing conditions. The need for a selective dismantling of hazardous building materials arises during demolition and renovations, after accidents caused by improper asbestos handling or in the case of an unacceptable risk to users or third parties. We will support you in assessing the dismantling requirements.

Technical and industrial progress during the last decade have often come at a high cost: the results of improper handling of chemicals and waste have resulted in contaminated sites. The lack of planning for safety equipment and work flows still poses a threat to our soil. With our comprehensive knowledge, we can manage these risks.

Our goal is sustainable protection of the atmosphere, water, soils and organisms. Climate protection and careful handling of resources make for a liveable environment. Legal requirements are the minimum for operational environmental protection. Forward-looking environmental concepts offer you potential savings and competitive advantages. We will plan and optimise individual environmental protection concepts for your business and support you during implementation.

Old industrial installations, dormant commercial and industrial sites, residential high rises from the 1960s and office buildings from the early 1970’s, which are no longer adequate for meeting today´s demands. First and foremost, our task is to compile lists of hazardous building substances and contaminants used in the construction. Consequentially we will design a progressive and appropriate process in dealing with hazardous building materials. At the same time, we will plan the dismantling and demolition while respecting industrial safety and emission control requirements: from the dismantling and demolition concept to licensing and execution planning right through to obtaining the necessary permits. For the tender of the designed measures we will prepare an agenda of services and support to the client throughout the allocation process with a team of specialists. We will manage waste disposal and tend to the organisational challenges of management and supervision of the dismantling and demolition work. These services are provided as a fixed price from a general contractor.

A detailed plan is necessary before implementing the actions to be taken. An approval plan is essential for the demolition application. The contractors performing the works need the execution plan. The list of services is the key to the calculation of the offer and for comparing efficiency. We will undertake the dismantling and demolition planning for you.

We deal with all types of raw materials; liquids, solids and gases – all over the world. We prospect for deposits, investigate raw materials as well as plan and compile surveys. Evaluating a deposit through a Pre-Feasibility Study and Bankable Feasibility Study pursuant to international standards, which enables the prospecting investor to undergo a financial commitment on a sound basis. Determining the presence of exploitable reserves is the most important criterion. Other decision criteria are technical recoverability, ecological and social impacts on the environment, and licensing aspects.

Deposits are an essential source for the survival of entire industries. They counteract the shortage of raw materials. Raw materials are very diverse – and so are their deposits. The prospecting of a deposit is the basis for successful raw material extraction. We will offer geological expertise combined with years of experience and technical prospecting services. This will guarantee you reliable planning, monitoring and evaluation during the prospecting period.

We test land, existing building stock, technical installations, operational risks and adherence to environmental requirements with due diligence or an environment due diligence. The extensive and complex testing requires professional competence, strategic thinking and interdisciplinary work. We will test and evaluate all environmentally relevant information sources. In this way, we will create transparency for your decision-making.

We all need energy every day. Consciously and unconsciously. Reduce your energy consumption and increase end-user efficiency. We will develop solutions tailored to your needs.

The environmental impact assessment (EIA) is the central eco-political instrument for environmental protection. Environmentally relevant projects are assessed for environmental impacts. As part of the regulatory approval process, the environmental impact assessment aids decision making on the permissibility of projects. It is the first hurdle for project implementation. With our detailed presentation of potential project-related environmental effects, the concept of measures and a balanced discussion of the options, we prevent failure of the project due to the EIA.

The environment and our living conditions determine our quality of life. Development entails changes. Sustainable environmental development is the result of many large and small projects. Environment – and occupational health legislation is extensive and varies worldwide. Environmental consulting covers many areas of responsibility: Risk identification, building assessment, early detection of harmful effects, operational environmental protection, location evaluations, information acquisition and utilisation. We will stay on top of things, so that you can make the right decision.

Today, decisions are complex. Often situations are difficult to see through. Strengths and weaknesses must be considered. Every property transaction requires that environmental risks be identified and quantified. Problems can only be averted if they are known about in advance. We will be your guarantor for due diligence procedures.

Environmental information systems are GIS and database systems for the recording and analysis of environmental data. With environmental monitoring, the continuous collection of large amounts of data is particularly important. Much of this data will be related to geographical information. Environmental information systems consistently collect data and make new analyses possible. Increase your efficiency with our environmental systems. We’ll help you gain new insights.

A technical environmental building evaluation is a complex and variable service package. It is worth it for every phase of a building’s lifecycle: development, operation, renting, ongoing maintenance, buying or selling, conversion or demolition. It is always worth reliably identifying, evaluating and managing environmental risks. We will offer you tailor-made solutions for your property type and it´s lifecycle phase.

Environmental planning is oriented towards desirable conditions for the environment and human beings. Environmental planning ensures the co-ordination of individual instruments and integrates environmental policy in all areas, such as spatial planning, individual plans and environmental impact assessments. We take environmental and social aspects into consideration. That way, we achieve sustainable development.

The ESG approach, which encompasses environmental, social and governance aspects, is too important to be relegated to a buzzword. So we operationalize this approach for our customers: The term ESG is booming. And not just because of the recent crises. The increase in importance is having an impact on markets, fashions, consumption and investment decisions. ESG is often defined very broadly and used as a synonym for sustainability.
In addressing the global challenges that also affect the Balkans and Kosovo, the ESG/Sustainability issue must be prioritized. HPC is your partner in ESG and sustainability. We support you in setting your sustainability goals, implementing and building an ESG management system in order to minimize your sustainability risks and take advantage of potential opportunities.

In the early 1970s, the German Federal Government presented its first environmental programme. The Federal Immission Control Act is intended to protect against harmful effects on the environment. And so, since then, many companies have come into contact with the law again and again. The example of the Hagedorn Group of Companies illustrates how HPC AG supports its customers in the authorisation process.

Biogas, in addition to the renewable energy sources solar and wind, is an important energy source. We use many raw materials: digester gas from sewage treatment plants, organic waste and renewable raw materials. Regionally available resources and energetically recyclable waste materials can be produced in an environmentally friendly way. What is special about biogas? It is natural energy obtained from organic material and delivers CO2-neutral heating, cooling, electricity and gas.

Preventive fire safety has been an important aspect of occupational safety for many years in building planning and inspection. The number of fires resulting in levels of material damage, injuries and death must be reduced. We will arrange safety targets for buildings and property related requirements with you. An integral fire safety concept is generally obligatory for special structures without specific building regulations or significant deviations introduced by the building authorities. We generate all fire safety measures up to final design on your behalf.

Each building leaves traces in the ground. Detailed knowledge of local conditions guarantees the economic viability of a structure and protects the surrounding areas. Our foundation consultation offers alternatives for an economic structural foundation and gives recommendations for the construction processes. We will get you on a safe and economical base.

We are experts in contaminants and all classic and innovative investigation processes, redevelopment and securing. We have experience from thousands of projects and are confident in our expert opinions and cost estimates. As a general contractor, we are a competent third party. For new usage, we guarantee that we will comply with public laws concerning redevelopment requirements at the fixed price including all enduring risks from contaminated sites.

You will receive planning as well as environmentally sound and selective dismantling and demolition measures while complying to all workplace safety measures with the optimal disposal methods and disposal services from one provider. As a general contractor, interface problems are foreign to us, as they cause delays. We will take on the responsibility for the whole dismantling project, the meeting of deadlines and providing cost security.

Geographic information systems (GIS) make spatial objects visible and link them to a database. Manage, analyse and visualise an extensive amount of diverse data graphically and quickly with GIS. GIS offers individual solutions for supply and disposal contractors and for city, space and landscape designers, as well as for “environment departments” in industrial companies. You define the requirements. We offer you the modular custom-built geographic information system that meets them.

Land, soil, earth and rock are our living space, and at the same time, the foundation of our construction projects. They are only safe as building sites when they are explored and evaluated. We offer you complete solutions from a single source, including complex challenges. Our experience and our perseverance ensure the success of your construction project.

Geothermal energy offers an economic and sustainable option for heating and cooling buildings. As expert planners for geothermal systems, we orientate our planning services in accordance with HOAI (Fee Structure for Architects and Engineers; AHO Booklet 26). We take on the basic evaluation/feasibility study, preliminary planning and pilot studies (thermal response test, pump trials), the design  and approval planning, as well as the implementation planning and contracting (service phases 1 to 7 in accordance with HOAI).

Through development previously unused areas can be used for residential, commercial and industrial purposes. These can be previous fallow lands or built-up areas undergoing a change of use. We help you to develop these areas with the required infrastructure.

Non-potable water, drinking water, mineral water and curative water – water extraction differs according to your requirements. Drinking water, mineral water and curative water must conform to much higher quality standards than non-potable water. With site surveys, planning and monitoring of the construction of wells and pipelines we provide a flawless delivery of quality to the consumer. With innovative geo-hydraulics, groundwater modelling and resource management methods, we create the conditions for legal protection and long-term usability of groundwater resources.

Clean groundwater and spring water is the most precious foundation of life. Our goal is to appreciate and protect it. We therefore explore aquifers, examine water quality and rejuvenate in case of damage. We have been dealing with groundwater projects for many years. We plan construction projects in groundwater particularly carefully – to protect the groundwater and prevent damage to subsurface structures.

Groundwater models mathematically describe groundwater flow and transport processes. They build a simple or complex picture of the aquifer and make it possible to address many questions and tasks using computer projections. We create precise problem analysis and solutions for your site. And at a highly professional level.

Hazard maps for heavy rain are the most important basis for structural measures to reduce the risk of flooding, precautionary planning and crisis management.

Farmland and aquifers in Baden-Württemberg are contaminated with paper sludge. There are both causes of and solutions for this large-scale contamination.
Anyone visiting the heart of the city of Hamburg, HafenCity (Harbour City), usually looks at the impressive new and old buildings – or at the wide water. But it is also worth taking a look at the ground. Only those who master the skill can build in a harbour – with sand, storm surges and an inrush of water.

Water is the basis of our life. Rivers and inland water bodies are the natural habitat for flora and fauna. At the same time, they are traffic and transport routes and popular areas for leisure and recreation. Rivers and inland water bodies also contain dangers. Floods can have devastating effects. We preserve natural resources and shape them so they can be used safely.

We can only protect what we know: geo-hydraulic measurements and investigations into groundwater conditions are important bases of hydro-geological exploration. With our test vehicles, we can perform pumping tests and all common drill-hole testing to a depth of 400 metres. We digitally collect all measurement parameters. We can evaluate the data on the spot. We gather information about aquifer structures to the best technical standards: diagnostic plots and transient-response curve procedures provide reliable aquifer guidelines, so that we can mathematically calculate the groundwater flow and make forecasts for the development of groundwater quality. We examine the groundwater quality with ingress pumping tests, multilevel sampling and other methods. In this way, cases of groundwater damage can be assessed and corrected.

With big data, the value of relevant information increases considerably. Big data makes it possible to create successful concepts and gain market shares. Provided you get a handle on the flood of information – uncertainty and lack of experience with information systems can waste your potential and damage your competitive edge. We support you to use information systems competently, so that you can quickly collect and evaluate data.

Regional economic objectives of investment-related infrastructure policies can only be achieved by thorough infrastructure planning. Infrastructure planning influences the competitiveness of regions, the promotion of economic growth and the improvement of region-specific environmental situations. We know the individual challenges of areas and regions. That qualifies us to be competent in current and future infrastructure planning.

The IED (European Design Institute)-Directive and the initial state report means new obligations for plant operators and industry. Die IED-Directive came into effect in November 2010. The aims of the directive were to standardize environmental specifications within the EU and to prevent unequal competition. Regulations (4 and 9 BlmSchV (Bundes-Immissionsschutzverordnungen) [Federal Emission Protection Regulations]) were adopted when the IED Directive came into effect. We will support you with all measures in the implementation of the IED-Directive.

During the last 100 years social prosperity has been growing at the expense of the environment, especially soil and groundwater. Contaminants are stored in former production sites, in landfills and in artificially filled sites. These contaminants pollute groundwater, surface water, crops and endanger human health. In the course of construction measures, these contaminants lead to higher costs and need to be disposed of. Authorities, owners and buyers require reliable surveys. This is the only way to safely assess potential threats, risks attached to new use and investment restrictions.

Life is constantly evolving. New buildings and installations are emerging on freely available land. Elsewhere occupied land is being redeveloped and returned to the economic cycle. Land recycling enhances urban land, revitalises soil, and is part of urban and rehabilitation planning. We offer services to promote land recycling and the integration of sustainable disused and usable land for the whole area from one sole provider.

Measure first, then act. Precise knowledge of location-related data is essential for nearly every construction project and many other projects besides. We collect this data for you with the most advantageous procedure in each case, and if you so require, maintain them in a geographic information system (GIS). Our repertoire includes GPS measurements, surveying with tachometers and accurate levels, as well as laser scanner measurements. We can offer you the use of state -of –the- art technology for an efficient, time- and- cost saving implementation in your project.

Even with successful methods of waste recycling, landfills will still be required in the future. Waste and residual waste fractions are still classified on an economic and ecological basis from I to III. Industrial waste can be deposited on lower landfill classes depending on the pollutant content. We can help you to extend existing landfill sites and set up new ones.

Landscape planning is an ecological and creative subject between the conflicting priorities of spatial planning, ecology, conservation and various other areas. It serves proactively as a key planning instrument of nature protection and landscape conservation. Areal- and profile-oriented landscape planning supports and steers economic development and helps to shape it in an ecologically sustainable manner. With our landscape planning, we have set ourselves the goal of maintaining the productivity of eco-systems as the basis of life for people.

There are no rivers in the capital of Kosovo. The Priština, its namesake, and the Vellusha disappeared in the 1950s – filled up with rubbish and soil. Rivers that did not disappear from the face of the earth are often contaminated in the Balkans – as are many soils. The reason: carelessness or negligent and ignorant handling of harmful substances as well as massive damage caused by war.

Part of the decommissioning process of a mine is to consider the landscape design and usage after the extraction of a deposit. The design of the landscape must ensure long-term safety, a low maintenance and sustainable use after completion of the mining process. Planning must take geotechnical, hydrogeological and landscaping factors into consideration. Based on this we can develop a complex and unique redevelopment plan for you.

Since ancient times, raw materials have been the source of prosperity and progress. Often in the past, the need for new deposits was the driving force for technical advancement. These days, sufficient raw materials are the basis for industrial production. A guaranteed supply of raw materials for industry is of high economic importance. We prospect and evaluate worldwide deposits for liquid, solid and gaseous materials. The extraction of raw materials through mining poses a great responsibility for people, nature and the environment on us. After decommissioning the mine, we design the plan for the post-mine landscape. We are also happy to develop individual flood scenario concepts for you, as well as post-flood concepts.

Health and safety for your employees are your top priority. High rates of absenteeism and disturbances in the workplace are costly and often have disastrous consequences for small and middle sized companies. It is necessary to implement accident prevention regulations and avoid accidents at work and health hazards. We develop company specific safety measures and monitor their implementation.

Occupational health and safety is often only an issue when it is too late and damage has been done – be it through an accident or through everyday work. HPC supports its clients in preventing this from happening. Selvi Kocak-Pasolar specialises in tech companies. The new hybrid working world poses completely new challenges.

In order to ensure you a smooth and therefore cost-efficient project, we integrate all customer-specific, legal and technical requirements from the BImSchG and the accompanying fields of law early on.

The BImSchG bundles the relevant legal fields in one approval process. For over 20 years, we have guided this complex process as an expert for approval processes in the environmental sector and for water‐polluting substances. From planning to commissioning: Everything from a single source!

Water care and water development are implemented through the Water Framework Directive. Proposals that safeguard the water supply and ecosystem, the landscape and the common good are approved. All measures are subject to regulatory approval. We utilize our room to manoeuvre to your advantage to reduce the cost of water maintenance. Channelling water runoff and improving ecological conditions are a must for us.

If the risk assessment reveals a need for redevelopment, we will find the best comparative redevelopment solution (retention or de-contamination). Initially we will develop specific and proportionate redevelopment targets, before we generate options for redevelopment solutions and after evaluating the cost effectiveness criteria. We will prepare the design plans and permit applications. We will assist you in making the right decisions. We will oversee and manage the redevelopment. We will take responsibility.

Contaminated sites can be old waste deposits on former landfills and former industrial sites utilizing chemical substances in their processes. Contaminated sites can pollute groundwater, surface water, crops and endanger our health. We systematically investigate suspicious sites and assess them in accordance with the BBodSchG and BBodSchV. We always assess individual cases and determine a specific course of action appropriate to each case. We focus on the solution, not the problem.

The interplay of people, goods and information is a prerequisite for technical progress. Continuous work for a mobility structure meeting these requirements contributes to this progress. We consider all stakeholders and act sustainably, cost-consciously and efficiently.

Roads and paths are one of the foundations of our life. We provide relevant and economical road construction which meets medium- and long-term requirements.

Numerous factors and individual assessment criteria affect the choice of location. We consider the location situation in conjunction with the customer’s specific requirements. In accordance with the company’s objectives we will take on individual location requirements and adapt them to the conditions of the alternative sites. We will analyse all the relevant factors, evaluate the basics and check alternatives.

Improper procedures in dealing with groundwater causes 80 % of all building damage. Poor judgement leads to damage and massively increased cost. Our experienced hydrogeologists and civil engineers help you maintain a dry building site. Our tools range from simple formulas to complex groundwater models. We examine the effects of large-scale drawdown. In so doing, we set benchmarks: through co-operation on the issue of construction water containment for highly acknowledged scientific publications (such as the “Grundbautaschenbuch”) and the taskforce on DIN 18305 “Water Containment Works”.

There is a high risk of occupational accidents for workers on construction sites and the immediate area. This is the building owner’s responsibility. We will offer substantiated safety planning, stringent implementation of all precautionary measures and constant communication with everyone concerned. Our health and safety coordinator will take charge of these duties.

The implementation of the planning procedures requires expertise in site management and supervision. We will continually check compliance with the requirements of the planning process, solve unforeseen problems and take care of your interests. At the conclusion of operations, you will receive a detailed report as a documentation of upholding all the applicable legal requirements.

Contaminated building debris needs to be monitored and managed on-site. This is essential for large quantities. We will oversee the occupational safety aspects. We ensure compliance with waste requirements. We eliminate unnecessary costs with the expertise and experience from thousands of construction sites.

After evaluating the soil conditions, we will define the targets for soil protection solutions at national and regional level. We will then clarify regulations with the municipal and environmental planning authorities. The catalogue of measures taken will be based on regionally relevant information and the relevant planning documentation.

The characteristics of soil and groundwater and their suitability for a building site are important criteria when buying real estate. Our experts investigate the conditions. We will give you recommendations for the right foundations. A good investment to prevent impairments and delays in construction.

When construction projects and their planning impinge on the habitats of rare and protected plants and animals, the legal requirements for wildlife protection come into effect. Right at the beginning of project planning, we assess whether relevant animal and plant species and their habitats could be affected. If that is the case, specialists investigate the […]

Building ground is capital. Sustainable and economic use pays off. Especially in inner cities, a new building must fit in with existing structures. Shoring is often needed in a building pit. Surrounding buildings, roads, pipes and sewers need to be taken into account. We offer you one-stop planning and security credentials. Through to the execution stage.

Many large companies in Germany have already prepared reports per the Non-Financial Reporting Directive (NFRD). This might give them an advantage in complying with the mandatory CSRD (Corporate Sustainability Reporting Directive) requirements.
Ambitious remediation of a polluted area instead of “out of sight, out of mind”. HPC AG is thoroughly remediating a pit filled with chemical and pharmaceutical waste, among other things, using state-of-the-art equipment for the Swiss-based Roche Holding AG. Excavating an average of 600 tonnes per day, and filling a total of 15,000 containers in a very confined space at a depth of 13 metres right next to a river – HPC AG, the general planner and construction manager, has shown that this is possible.
The greenhouse gases caused by HPC AG are recorded and compensated. This makes us one of the first companies in our industry to voluntarily compensate for emissions.

Contaminated sites, contaminated locations and buildings, emissions and immissions of pollutants compromise product safety and occupational safety and lower the value of the product and building. Chemical substances must be recorded and quantified. Dangers are not immediately recognised. This is particularly true for combined exposures to pollutant mixtures. Our toxicological risk assessment tests the statutory risk thresholds, for example, cancer risks from IKR: 10E-5. For unacceptable risks and hazards, we will define, with you, location specific action quality and sanitary procedures. We will support you in your risk assessment.

Environmental influences increasingly jeopardize vital drinking water supplies, rivers and lakes. Industrial effluents are often polluted and require treatment. Our wastewater treatment focuses on the multiple use of wastewater and water pollution control. With innovative treatment processes, we achieve a resource-saving reuse for municipal and industrial purposes.

Recycling and waste disposal often requires sampling and analytical studies. A simple separation of building substances lowers expenses. We investigate waste materials and the soil conditions before commencing construction. We sample materials to be disposed of and provide the appropriate material categorization declarations. We know the regional requirements for disposal regulations.

Both on-site storage capacities and available time are often scarce. We determine the different qualities of debris and soil as well as the different waste categories in advance. We arrange approval of intermediate storage areas, disposal and recycling paths and develop disposal concepts based on the investigation results and evaluation. A complete disposal concept ensures proper site planning and reduces costs.

Many obstacles make the disposal of building materials and waste difficult. We will advise you on environmental research, recycling and disposal concepts pursuant to technical and economic criteria. We will co-ordinate the interfaces between all involved parties for you.

Cleaning and disposal of industrial wastewater is particularly complicated and costly. Systematic analysis and evaluation of the water and wastewater-related parameters on site can greatly reduce costs. Aspects of wastewater management are the type of water supply, the average consumption of water and the contents of the wastewater. We reduce the production costs. For us, environmental protection means reducing water consumption and reusing waste products. Waste products are sand, screenings and valuable materials, such as sewage sludge, which contribute to energy extraction.

Water is our most important resource. With us, you can identify and eliminate risks in your water supply. We customize methods and processes to suit your needs. Through efficient resource management you maximise your savings potential. The sustainable management of water resources is certifiable. We ensure the optimal use of resources.

Clean drinking water ensures the sustainable development of whole regions. Sources of water include river water, groundwater and sea water. The quality of the raw water determines the technical solution for its processing. We ensure that the processed water will be distributed and temporarily stored in transport networks. So the water in the distribution system reaches the consumer.

Our wastewater is supposed to be clean. But hardly anyone is interested in what exactly happens; the main thing is that the result is right. And that’s what HPC AG cares about – envisioning a future that is not so far away.

A healthy working environment motivates employees, creates satisfaction, and increases productivity. In production areas, high risk areas, and in the office, occupational health and safety is essential and at the same time a recipe for economic success. Fewer accidents and shorter outage times means fewer extra costs leading to potential savings on insurance expense. We will support you in coordinating occupational safety measures for your company.

Heavy Rain and Flash Flooding

When rain becomes a danger

Model. Analyse. Act.

In future, extreme weather events will occur more often due to global climate change.
Risk maps for intense rainfall are the most important basis for construction measures for reducing the risk of flooding, contingency planning and crisis management. We use a wide variety of support programmes, guidelines and handbooks for protection against climate change, especially on the subjects of intense rainfall and flash floods.

We use all available information sources, from quick analysis to detailed risk evaluation, to create individual solutions for you – beginning with planning protective measures to the implementation of management tools.

The goal is to protect life and limb and to prevent or minimise damage from future intense rainfall and flash floods as much as possible. We are available to you for consultation throughout the entire process.

Our German Association for Water, Wastewater and Waste experts for intense rainfall prevention and our municipal water management engineers are happy to help you:

Flow path analysis and site risk assessment

The initial evaluation of the flash flood threat to sites is performed with suitable software tools. Thanks to high-resolution, comprehensive topographical information, a risk assessment can be carried out cost-effectively, for example as part of a due diligence study.

The programmes used by HPC AG allow a variation of rainfall amounts and, at the same time, visualise the at-risk areas in the site and surroundings. A flow path analysis and evaluation of the catchment area round out the intense rainfall risk assessment.

In the event of a risk from intense rainfall, detailed modelling can be decided on in the next step. In addition, the effects of compensation measures in the area around the site, such as rainwater retention basins, can be evaluated in advance.

Development of 2D flow models based on digital terrain models

Digital terrain models – the basis

Digital terrain models (DTM) are computer-based depictions of the terrain. DTMs form the basis of modelling and calculations, such as for the surface discharge. The reliability of the modelling results depends on the level of detail of the DTM. Therefore, the basis and design of the model are adjusted to fit the goal of the modelling.

HPC AG selects the appropriate baseline data for every issue and, if necessary, enhances the existing terrain model with laser scanning, drone overflights or classic surveying.

The terrain surfaces of a DTM (digital terrain model) are refined with edges (buildings, kerbs, terrain lines).

Hydrodynamic 2D surface calculations are required for realistic evaluations; in some cases, a coupled evaluation is also a good idea. This means coupling the hydrodynamic 2D surface calculation with a 1D calculation in existing culverts or municipal sewers. Then, water in the model can flow into, but also out of sewers onto the surface, an overflow can occur in the sewer or manhole covers can lift under pressure (cf. accompanying video).

Surface run-off can be generated from areal precipitation, rain radar data and surface run-off parameters (SRP). Soil-specific seepage losses reduce the precipitation on the ground surface from which the drainage occurs. Surface roughness

specific to the use slows drainage. In short: In the event of intense rainfall or flooding events, the actual conditions, including possible interactions, can be depicted in the required precision with the right tools.

Video animations and clear 3D views of models and events (see accompanying example) support our customers and their employees in gaining an idea of the risks to be expected.

Simulation and heavy rain risk map

Reports of intense rainfall events can be seen in the news almost every day. The warning times are extremely short. Unlike flood waters, the exact place and time of an intense rainfall event, which can lead to flash floods in urban areas, can scarcely be predicted.

It can happen anywhere in Germany, cause high material damage and pose a serious risk to life and limb. There is no protection against the risk of extreme weather, which includes intense rainfall events. But every city, every community and every citizen can take precautions.

If we are aware of a danger, we can prepare for it. Computer-supported simulation models help us to visualise potential rainwater drainage. Intense rain cells can be emulated in the computer model and the drainage on the ground surface simulated, i.e. reproduced.

The basis for such simulation models is the digital terrain model with topography, land use, surface condition and other parameters. Using a two-dimensional, hydrodynamic numeric surface run-off model, the drainage routes, flood extents, speeds and flood depths are calculated. The result is intense rainfall risk maps.

The intense rainfall risk map (IRRM) is the first building block of municipal intense rainfall risk management (IRRM). Intense rainfall risk maps from HPC AG answer the questions:

 

  • What are the water’s flow paths?
  • How fast will it flow?
  • What water depths will occur?
  • Which buildings and areas will be affected by flooding?

What might happen?

If there is flooding due to intense rainfall, it is important to know how high the water will be. At a flood depth of only 10 cm, water can make its way into a building through light wells and leaky basement windows. Staying in flooded basement rooms is potentially deadly. At flood depths of over 50 cm, the static pressure rises so strongly that seals fail, especially for doors that open inward. Water levels and flow speeds can be read from the intense rainfall risk maps. For example, at a water depth of 15–20 cm, doors can no longer be opened inward. There is already a risk to life and limb (adults) at a flow speed of 0.5 m/s (ca. 1.8 km/h).

Risk Analysis

​Risk management minimises negative consequences

The integration of risk information is an essential part of risk management processes.
The intense rainfall risk map (IRRM) is the key element in describing danger and identifying risks. As part of municipal intense rainfall risk management (IRRM), trouble spots are identified in consultation with the fire brigade and construction facilities.

The flooding depths and flow speeds on the property are used to determine the danger. Then it is a matter of blending the flood zones with the properties at risk. The results of the flood risk are compiled with possible damages and vulnerabilities. Areas and properties especially at risk must be identified: How high is the potential damage? Is there a nursery school in the flood zone?

A high risk exists in places where there is a high danger of flooding (e.g. flood depths of 55 cm) as well as a high-value property with high damage potential (e.g. flooding of an engine pit). Population groups with an increased need for protection and with limited mobility must be protected. Especially vulnerable institutions include nursery schools and retirement homes. In addition, important infrastructure for crisis management (fire brigade and medical services) must be operational in the event of an incident. Especially critical places are determined and documented as part of the risk analysis. That way, emergency personnel know where the danger is greatest.

As if using a magnifying glass, property‐related risk analysis can take place on the building level. This detailed analysis examines the risk to the building (e.g. possible water penetration, effect on technical infrastructure and people) and the vulnerability of the property at risk. Risk estimation and site-appropriate recommendations for preventative measures round out the risk fact sheet.

Hazard prevention

Measures for protecting against heavy rain are developed for areas and buildings needing protection. In the process of municipal intense rainfall risk management (IRRM), the third building block is the action plan or hazard prevention. Hazard prevention is achieved either through organisational precautionary measures or through structural measures. The creation of retention areas, the construction of technical protection systems and harmlessly directing and guiding surface flowing water are examples of structural protective measures. The goal is prevention, and, where that is not possible, at least minimising the damage from intense rainfall events.

Site-appropriate emergency plans can save lives in the event of flooding. As part of the structural measures, dams, terrain modelling or protective walls, for example, can be placed at appropriate places in the terrain. If the water cannot be diverted or retained, property protection comes into play. Major damage can often be avoided through simple individual measures. Examples include the installation of spill barriers and water pressure-tight windows, securing light wells and basement access points, and the adaptation of building services.

Sewer system simulation

Water that must be directed in a controlled manner is everywhere in our everyday lives. Waste water, that is sewage from households, commercial buildings and industry, must be purified before it can be reused or drained away. More visible, on the other hand, is precipitation water, that is all water that comes from above and strikes the ground, such as rain, snow or dew. As a rule, precipitation water is clean and does not need to be purified before being drained. An exception is precipitation water that falls on dirty surfaces, such as roads. This must be purified before draining. That is a large amount of water, especially during intense rainfall. The water has to be retained in order not to overload the sewer system.

Sewer systems consist of a variety of elements, such as shafts and catchments, retention systems with throttled discharge, pumping stations and much more. All of these elements affect the water run-off with respect to both time and volume. A complex system quickly arises in which even professionals are scarcely able to estimate the sewerage load easily.

Before you’re up to your neck: Create an overview

A computer-supported sewer system simulation is needed to depict and examine the interplay of the individual elements of a sewer system or to assess the fundamentals of the sewer system. To do this, all the elements of a sewer system are measured, their hydraulic effect described and then stored in a database: the sewer register. The flow in the sewers can then be simulated by software. Managing even the most complex sewer system becomes manageable.

Inspection and vulnerability analysis

In order to achieve a realistic risk assessment of the possible dangers from heavy rain and flash flooding, extensive site and property analyses are necessary. That way, weak points and risks can be identified. A hazard assessment should be performed as a precautionary measure after every flooding event resulting in damage. However, it is also a good idea when there have been no heavy rain events in recent years. When potential risks and hazards are recognised, suitable protective measures can be made in a timely manner.

An initial estimation of potential hazards from heavy rain and flash flooding is made by inspecting the municipal territory together with representatives of the relevant authorities. Here, the focus is on questions regarding the starting points of the last floods and the location of flood zones and sites where the greatest damage occurred. If there have been no intense rainfall events in recent years, then, for example, historical records can be used and witnesses from that time questioned.

Furthermore, topographical conditions can be analysed and at-risk areas identified by the inspection. These may stand out due to their location on a body of water or the lowest point of the community, for example.

Along with the topographical conditions, the development structure, the building situation and the infrastructural facilities can be examined during the inspection, since these are critical for the water’s flow paths and damage potential.

The results of the inspection serve as the basis for further steps for creating a complete hazard assessment.
