Simle Middle School Addition

Bismarck, ND

The original school, built in 1961 was added onto in 1991, and received renovations in 2007. In 2017 it took on another expansion utilizing architectural precast concrete wall panels in lieu of the existing structure that consisted of brick and block materials. The architectural capabilities that precast concrete wall panels offer allowed the design team to be creative and achieve the desired look tying into the existing structure aesthetically, presented a solution for the tight site conditions, and accelerated the construction schedule.

The board awarded the general construction bid to Northwest Contracting for the base bid amount of $6,190,600, plus the gym addition bid amount of $1,052,300 and the concrete parking lot bid amount of $8,700, for a total general construction bid amount equaling $7,251,600.

They awarded the electrical bid to Denny’s Electric for the base bid amount of $1,197,000, plus the gym addition bid amount of $90,000, for a total electrical bid amount equaling $1,287,000

The mechanical bid was awarded to Advanced Mechanical for the base bid amount of $2,325,500, plus the gym addition bid amount of $210,430, for a total mechanical bid amount equaling $2,535,930.

In addition, the low bid for materials testing was from Terracon in the amount of $47,099 and the low bid  for testing and balancing was from Balancing Professionals in the amount of $25,830.

The insulated architectural precast concrete structure consisted of 83 panels amounting to 29,314 SF with the tallest panels being over 42′-0″ in length due to the varying site elevations. These panels were all cast indoors in a climate-controlled facility in 34 days and were stored at the plant, then taken when needed on site by the general contractor. The use of embedded electrical items during fabrication allowed Denny’s Electric to compress its on-site time and gave the building a nice smooth durable interior finish in the exposed areas, eliminating any surface-mounted items.
