Quality Assurance


Quality is the catchall term often thrown about in the industry to express the intention that things will be built to expectation; however, it is frequently a source of disappointment when the intention fails to materialize into execution.

At WSN Construction, we approach all tasks with methodical quality assurance procedures. Pre-Construction, Construction and Post-Construction activities are structured to ensure that at no time we fail to support our project partners and meet their expectations.

Careful structure of tendering and review are our first step to understanding the intention of the project, which allows us to best help our project partners in attaining their goals.

The use of detailed project execution plans, comprehensive ITPs, incremental design reviews, constructability reviews, and a collaborative transparent process allows WSN Construction to ensure successful project execution and client satisfaction.

No matter how unique the nature of the construction, WSN Construction is able to distill the requirements into a plan that allows all project team members to review, participate, and design the execution.
