Utah Plumbing and Heating Contractors

CROCKETT, Chief Justice: Plaintiffs, an organization of plumbing contractors and three other trade associations, including some from Weber County, sued to enjoin defendant Weber County Board of Education from installing a sprinkling system on the Roy High School football field. Plaintiffs contend that the defendant's use of its own maintenance employees to put in the sprinkling system was a violation of Section 53-11-1, U.C.A. 1953, which requires advertising for bids "" any schoolhouse is to be built"" or any improvement constructed costing over $20,000.
