Specifications include, but are not limited to: Review historical data in the form of record drawings to familiarize with site and situation. Provide Mechanical design calculations to determine: Type and quantity of expansion joints required; whether existing pump units are sufficient for proposed loop replacement and operating temperatures will meet existing requirements once new system is operational; and pipe insulation is sufficient to maintain required temperatures in hot and chilled loop. Review of design for corrosion prevention. Provide Structural design calculations to determine: Required anchorage of pipe supports, concrete channel design including water intrusion and reinforcement, and seismic-related requirements for all proposed supports.
