To ensure continual design quality throughout the complete design and construction process, it is prudent for the project manager to procure, collate and assess working drawings as work progresses on site. This could include components, fixtures and fittings, key construction details and relevant schedules for approval. This provides the client with the opportunities to investigate the next level of detail as well as ensuring that the finer detail is not overlooked. The fenestration and fitting of this picture window for example, is critical to the success of this aspect.
