I would never suggest a fire pump on each run-in. Hopefully the site has been thought out and the loop supplying the new building can be boosted through the pump(s).

I question multi-fire pumps? You say the building has a looped water supply? Is the water supply part of a larger grid system or is the loop supplied from a single source, and for this project only? What I'm getting at, is it may be preferable to have the fire pump supply the site main (Loop) rather than the individual risers. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O. Box 882136 Steamboat Springs, CO 80488 Tel: 970-879-7952 Fax: 970-879-7926 You have 820,000 sq. ft. and only one run-in? Say it isn't so. You need to break up these systems and provide for multiple run-ins. If the fire pump is necessary to make the systems work then I see no problem with submitting a primary and backup fire pump for this size and occupancy of a building. I mean almost a million sq. ft and 10,000 people? What's the value of one life versus a fire pump, for the legal award for one loss you could buy quite a few pumps. Craig L.
