About CSI~QA

Developing Strategies » Obtaining Solutions » Achieving Quality Buildings

We provide construction site inspection & quality assurance to construction projects across London, and the surrounding area including, Bedfordshire, Cambridgeshire, and Hertfordshire.

At CSI~QA, we help projects to pass an NHBC visit first time, reduce after sales costs, and increase customer satisfaction. We are proficient in all construction methods and offer a tailor-made Technical Audit service.  We can visit your project periodically, at specific stages or as a one off.

We highlight actual or potential defects on site drawings, referencing recognised guidance and approved documentation to provide a comprehensive report designed to help on site teams improve their understanding of the issues.We also support businesses with tailored training packages, from onsite toolbox talks to developing training plans for operatives that are SMART

With the use of social media becoming more prevalent, a small defect can become a large-scale problem, damaging your reputation, and tying up finical and personnel resources.  Ensuring that the construction is built correctly on site requires a process to be followed from inception to completion. We provide an independent defect management solution identifying current defects and potential problems, referencing up to stands and approved documentation.

We report these to you in a comprehensive, tailor made report, highlighting areas on existing plans and drawings. The result is a reduction in the company’s costs for customer services and, more importantly, an improvement in the customer experience and brand image due to fewer complaints. We can also provide training packages to assist in reducing the number, repetition and severity of defects.
