CQA/CQC stands for Construction Quality Assurance/Construction Quality Control. All Vapor Intrusion Barrier systems should be inspected by a certified professional with experience in these systems to ensure they have been installed properly. Starting at the pre-construction phase, we work with the governing agency, the local Building Official, the General Contractor, the product manufacturer and sub contractors to establish an acceptable guideline for installation of the systems – as well as monitoring, documenting and reporting our findings. We are instrumental in opening the lines of communication between all parties involved with the project to ensure a smooth installation and monitoring process.
