After construction starts on a project, W&A can provide services such as inspection of mock-up assemblies and the production work actually on the building.

With mock-ups (whether wall or roofing assemblies) the goal is to help the Contractor demonstrate understanding of the Architect’s desired appearance of the constructed exterior envelope, but also the detailing needed to achieve watertightness and durability – as valuable as the Architect’s desired appearance of the new building. W&A can assist with site visits and inspections of such mock-ups, and including water testing where appropriate.

When production work begins, W&A commonly provides site visits and inspection services. This can be very focused on a particular trade that is in progress (masonry or windows or roofing for example), or can include top-to-bottom observations and inspection of the entire building envelope. Such site visits are typically provided on a periodic basis, at a frequency and length tailored to the Client’s (Architect, Owner, or Contractor) concerns and budget limitations.

Typically each such site visit includes providing verbal feedback immediately to the Contractor and its Subcontractors, and the Architect. We then commonly prepare a written report presenting our observations and findings during a site visit, with recommendations as appropriate for adjustments or corrections – all with our focus on building exterior watertightness and durability with the completed building envelope.

Also during construction, W&A can provide water testing services to check the performance of completed work. We commonly perform testing of installed windows, curtainwalls, flashings with exterior cladding systems, and other assemblies. We perform the common major ASTM, AAMA, and other construction industry standard tests, and we also perform a few tests of our own development – to help check completed construction for watertightness.

At the end of a project, W&A can also assist the Architect with the performance of Substantial Completion or "Punchlist" inspections of the building exterior envelope, based on our focus in this area.
