The South Sanpete School District has awarded two contracts totaling more than $1.5 million for classroom additions to two schools that have overcrowding problems.

The contracts have been awarded to Valley Builders, Gunnison, which in both cases was the low bidder. Ten other firms submitted offers.Valley Builders will be paid $759,000 for an addition to Gunnison Valley High School that will provide nine new classrooms. According to the terms of the contract, the new rooms will be ready for occupancy by mid-January 1992.

The school is now utilizing a two-unit mobile classroom and is holding classes in the lunchroom.

Valley Builders won the Ephraim Middle School contract with a $756,000 offer. The addition on the north side of the building will include four classrooms and a gymnasium and will increase the school's capacity by about 100 students. Enrollment is now 421. Valley Builders has 240 working days from March 20 to ready the addition for occupancy.

A bond issue approved by the voters last spring will provide the funds for the building program. Because the bonds were sold when interest rates were low, the South Sanpete District will save about $30,000 in interest over the life of the bonds because interest rates are now considerably higher, said Paul Gottfredson, district business manager.
