Payment Certificate and As-Built

At Trigen Engineering, we maintain unwavering commitment to engineering discipline not only during the design phase but also throughout the delivery and operation process of a project. Here are two critical services that ensure the successful completion of this process:

Payment and Quantity Surveying Management

We match the financial value of on-site progress not with data on paper, but with actual workmanship on the ground. By verifying the conformity of each quantity, material, and workmanship used in electrical and mechanical components to technical specifications, we build a bridge of trust between the employer and the contractor. With the detailed progress payment documents we prepare, we maintain budgetary discipline for the project and present a transparent financial statement at every stage of the investment.

As-Built Project Design

The construction process is dynamic; revisions to the design may be made during implementation due to site conditions. We meticulously document these changes in the final stages of the project, preparing "As-Built" projects that accurately reflect the finished building. These projects are the digital memory of the building; they allow you to know the exact location of installations behind walls or inside suspended ceilings during any future maintenance, repair, or renovation work, saving you significant costs and time.
