Better use of the indoor air quality classification at construction sites
By following the requirements of the P1 cleanliness class at construction sites, a lot can be done regarding the quality of indoor air in buildings. Although the requirements were created almost 20 years ago, they are still not used without problems. This experiment tests ways of facilitating P1-compliant construction.
What kind of problem is the project trying to solve?
The working methods used during construction affect the indoor air quality of the completed building and play a role in possible indoor air problems. The quality of indoor air can be enhanced during construction by observing the requirements of the so-called P1 cleanliness class at the construction site.
If the client or the developer aims at the best possible indoor air quality, category S1 or S2, the operators at the construction site must undertake to observe the requirements of P1 cleanliness class to ensure that impurities produced in the construction phase are not carried into the building when the building is used.
The first P1 requirements were introduced almost 20 years ago. In practice, P1-compliant construction is still found cumbersome and expertise in applying the regulations is lacking at building sites. When clients and subcontractors are not familiar with the P1 process, work gets delayed and costs increase.
Objective: A more easily understandable P1 process
The main objective in the experiment is to make the P1 requirements and compliance with them a concrete and easy process for developers and subcontractors to understand and adopt. We will collect together the best practices for the construction phase and draw up a set of concrete guidelines for meeting the P1 requirements.
What is done in this project?
The experiment examines and tests how P1-compliant construction can be clarified with process models and visual work instructions. At the same time, we determine the most common mistakes causing compliance with the P1 requirements to fail and look for reasons for the problems.
More easily understandable P1 instructions and a compilation of best practices will directly benefit the developers, engineers and designers, contractors, subcontractors and foremen at the construction site. All users of the building will benefit from cleaner indoor air.
