A GOOD DESIGN ANALYSIS SAVES MONEY!
ISSUE:
Improved A/E performance during design can lower construction costs.
BACKGROUND:
ProCATS (Proactive Claims Analysis and Tracking System) data shows a number
of unnecessary items were specified on projects because the A/E hadn't done a
proper design analysis.
DISCUSSION:
Examples:
1. A specified duplex fuel oil transfer pump set for an emergency generator, was
unnecessary because another duplex transfer pump set was provided on the day
tanks. The pump set on day tanks was adequate to pump oil from the underground
storage tanks to the generators, and therefore there was no need for the second
set of pumps.
2. Two fire alarm pull stations, gongs, and associated conduits and wiring were
deleted after inspection by the Fire Protection Consultant at the construction site.
The Fire Protection Consultant decided these were redundant, and therefore could
be deleted.
3. Twenty four back draft gravity dampers were deleted because: (1) they were
impeding air flow from exhaust fans; and (2) the dampers were unnecessary since
the fans were required to run 24 hours a day.
RECOMMENDATIONS/CONCLUSION:
1. Item 1 could have been avoided by a proper design analysis.
2. Item 2 could have been avoided if the Fire Protection Consultant had done a
more thorough analysis in the design phase and not relied on the construction
inspections to correct design issues.
