Proving out design and construction for anticipated performance can be troublesome for Owners, Engineers, contractors and equipment vendors. Components, systems and equipment included in a construction project occasionally have to be online for relatively long periods after commissioning and be subjected to “real life” conditions before performance can be demonstrated. The long waiting period required to adequately define performance can exceed contracting and warranty mechanisms that limit the post-construction evaluation window to one year. This is particularly true for combined sewer overflow (CSO) or stormwater projects that require evaluation of system performance during multiple significant wet weather events of varying duration, intensity and/or frequency. This paper describes several innovative approaches to evaluating the performance of projects, post-construction, including: full-scale testing, computational fluid dynamics (CFD) modeling, flow metering and monitoring with SCADA.
