We have prepared an offer dedicated to developers, architects and real estate offices. Check the scope of our services and find out how our experts can help you.
WESSLING Poland offers all the services you need from a single source: from consultancy at the investment planning stage, through sampling and laboratory testing, to the interpretation of results and recommendations for action.
The Construction Law Act changed in September 2020. Among the significant changes introduced by the new regulations is the division of the construction design into three parts and the definition of the scope of studies, which requires carrying out tests and soil checks even for small objects.
From the point of view of construction risk, when determining the geotechnical foundation conditions, the designer should in any case, even in the case of small objects and single-family houses, at least minimally refer to the following issues when determining the geotechnical foundation conditions:
The obligation to perform sozological tests should be emphasized. According to the above regulations, even for small objects, a competent person should determine the risk of contamination of the substrate. If it is necessary to perform chemical (sozological) tests, which takes place mainly in post-industrial areas or located close to operating industrial facilities, specific tests should be performed in an accredited laboratory and in accordance with the Regulation of the Minister of the Environment of September 1, 2016 (Journal of Laws of September 5, item 1395) on the method of assessing the pollution of the Earth's surface. In any case, not only laboratory tests, but also sampling should be performed in a certified manner and with appropriate quality. It is highly inadvisable to take samples with the use of a scrubber due to the washing out of pollutants during the collection.
We base the services of WESSLING Poland on the professionalism, experience and specialist knowledge of our employees, which is why we offer our clients high quality research and consulting, as well as support at every stage of the order. We strive to make our offer as comprehensive as possible and tailored to our recipients, so we will be happy to adapt it to your needs as well.
Our experts will help you at every stage of the investment. Both at the stage of purchasing the plot, allowing to make the right decision and avoiding additional costs, and at a later stage, by conducting measurements for the certification of buildings showing that it was made in accordance with the principles of sustainable development. We encourage you to familiarize yourself with the details of our offer.
Performing a research well allows for taking samples for further analysis in order to determine the physicochemical and mechanical properties of the soil. This is the basic knowledge for determining the influence of soil on future construction.
It is a type of field research which, by pressing, driving and screwing in the probe, gives a picture of the specifics and condition of the ground for the planned investment. Probing allows you to determine the depth of deposition of individual layers and their geotechnical parameters.
Before commencing the investment, the developer should perform soil and groundwater tests in terms of pollution. It may turn out that the soil of building plots contains contaminants of significant concentrations, related to the previous purpose of the site and the type of activity carried out, which penetrate into the groundwater, and therefore remediation is necessary. Since this obligation lies with the owner of the plot, the research preceding its purchase may protect the investor against additional costs, as the costs of remediation may exceed the investment costs.
Conducting remediation or construction works involves the generation of waste that requires appropriate management. Some of them can be reused in a different capacity, as a secondary material, and others must be disposed of. Disposal costs can be high, therefore the decision on the further use of the waste is made after it has been subjected to laboratory tests for contamination and an assessment of the possibility of its recycling.
Geotechnical opinions are necessary for investments requiring an architectural and construction design. They are prepared in order to define the geotechnical category of the object depending on the anticipated complexity of the ground conditions and to determine the necessary geotechnical tests that must be performed in the area of the planned investment. Thanks to such an opinion and appropriately selected research, it is possible to minimize the costs of foundation of a building structure.
Documentation of the subsoil research together with a geotechnical opinion constitute the basis for obtaining a building permit. It determines the type of subsoil, its properties and strength characteristics, as well as the groundwater level, the stability of embankments and excavations.
They are carried out together with the documentation of the ground tests and predict changes in the properties of the ground, determine geotechnical parameters, safety factors, bearing capacity and settlement of the ground, the impact of soil and groundwater on the structure, and the data needed to prepare the foundation design. All this to ensure the safety of the planned facility.
The geological works plan is necessary to obtain a concession for their execution. It defines the purpose and rules for conducting geological works, including information about the type of documentation that will be created as a result of them, as well as the work schedule and determination of the area on which they will be conducted.
Complicated ground conditions require the preparation of a separate geological and engineering documentation containing information on the expected environmental impact of the designed facility and on geodynamic processes. Appropriate adaptation of the project to difficult ground conditions will allow you to avoid unexpected delays and wrong decisions.
The geotechnical conditions for the foundation of buildings are presented in the form of a geotechnical opinion, ground research documentation and a geotechnical design. The form and the scope of the necessary tests depend on the geotechnical category of the building structure. We help in adapting the documentation to the current needs of the client.
An environmental due diligence audit applies when a property changes ownership. Thanks to it, it is known before making a decision to purchase real estate which obligations towards the environment will be imposed on the new owner. Investors decide to conduct a due diligence audit in order to be able to make a fully informed and risk-free decision to acquire the property.
The environmental part of due diligence consists of two phases:
Phase I - review of legal requirements in the field of environmental protection along with the identification of potential pollution outbreaks of the soil and water environment,
Phase II - recognition by taking and analyzing soil and groundwater samples.
The BREEAM certification system is a multi-criteria method of assessing the environmental impact of a newly constructed or existing building. One of the criteria assessed is indoor air quality. This is one of the most important aspects of a building's comfort of use assessment, as we spend most of our time indoors, and the quality of indoor air strongly affects our health and well-being. Appropriate measurements are carried out to check the air quality inside the building.
