I am bidding on removal and replacement of an existing dry pipe system. This is about 1,000 feet of 3 inch. Part of the specification is “Contractor shall submit working plans that have been approved by authorities having jurisdiction, including hydraulic calculations, prior to starting work.”
Is it normal to have new calculations done when just replacing rusting pipes? If so, where do you draw the line at needing new calculations? There has been new construction, since the building was built. Three new low hazard buildings have been built, with a new low hazard rehabilitation facility going in a block down the street. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
