Our services to ensure good indoor air quality and high-quality concrete structures cover the entire life cycle of a building from design to operation and repair. We are responsible for ensuring the quality of construction work during new and renovation projects and for monitoring after commissioning.
We serve customers in matters related to the management of humidity, cleanliness and airtightness, the functionality of the ventilation system and the quality assurance of concrete during construction sites. In addition, we offer a comprehensive range of concrete testing services.
Our quality assurance experts assist the customer at all stages of the project
Quality management services in the design, construction and operation phases can be used to ensure the functionality of structures and building services systems and to prevent quality problems in the finished concrete structure. The overall planning and implementation of quality management is always done in close cooperation with the customer.
In the design phase, the quality management expert is able to effectively influence the quality of the indoor climate of the finished building. We design the most functional and easy-to-implement structural solutions and materials.
The quality management expert comments on and, if necessary, makes suggestions for improvements to the plans and building description from the perspective of the factors affecting the indoor climate quality of the completed building. As the design phase progresses to applying for a building permit, a moisture management coordinator will be appointed for the project, who will prepare a moisture management report during the permit phase.
In the design phase, as a quality assurance measure for concrete, preliminary tests are performed on the concrete. Preliminary tests determine the properties required by the concrete plans and ensure that the concrete recipe is functional. Preliminary tests are always planned on a case-by-case basis, taking into account the requirements for concrete quality assurance.
During the construction phase, we ensure the implementation of the agreed quality assurance measures and our guidelines for preparing a cleanliness and moisture management plan. Concrete quality assurance during construction is also an important part of the overall quality assurance of a construction site, and well-implemented quality assurance can prevent quality problems in the finished concrete structure.
On-site quality assurance measures include regular cycles (humidity and cleanliness management), tracer tests, air leakage measurements, humidity measurements and condition monitoring measurements, as well as the production of concrete specimens and concrete air volume measurements in connection with castings, and thermal management of solid castings. Regular meetings and site tours ensure that site conditions are kept up to date and able to respond quickly to changing situations.
During the commissioning phase, we check the IV measurement protocol as well as the level of system functionality and final cleaning of the premises. The conformity of the finished concrete structure can be assessed by hammer tests, tensile strength tests and, if necessary, by the strength properties of the structural test pieces. We also offer expertise in various problem, damage and complaint investigations of concrete structures.
At the end of the warranty period, we participate in the warranty inspection of the warranty period, ensure the implementation of the maintenance measures planned during the maintenance phase, and carry out a user survey on the humidity and indoor air performance of the premises.
