Project Update Boyd Lake The construction contract for the Boyd Lake High-Level Outlet Structure was awarded to Moltz Constructors in December 2014 and construction occurred from January 2015 to May 2015. The construction contract exceeded the engineer's final design estimate by $33,587. Construction was completed on schedule and included two change orders totaling $24,090. Horseshoe Phase 1 Horseshoe Phase 1 included the installation of the high-level outlet gate. The Company agreed to allow Larimer County's contractor to install the gate as a part of the County's adjacent spillway box culvert and county road bridge replacement project. Therefore Phase 1 was performed by the County and its selected contractor, with the Company reimbursing the County for work associated with the gate. Construction was completed over schedule resulting in an increased construction cost of $116,737 and increased construction observation cost of $188,260. Horseshoe Phase 2A & 2B Horseshoe Phase 2 includes connecting the new high-level outlet gate installed in Phase 1 into Boyd Lake. The construction contract was awarded to Moltz Constructors in March 2015. In cooperation with Boyd Lake State Park, it was agreed to build Phase 2 in two phases to avoid summertime construction. Phase 2A consisted of the outfall into Boyd Lake and was constructed between March 2015 and June 2015. Phase 2B consists of tying the gate built in Phase 1 into the Boyd Lake outfall built in Phase 2A. Construction began in September 2015 and is on schedule for completion in December 2015. After work was nearly complete on Phase 2A, a miscalculation in excavation amounts, additional select fill, and additional rip-rap were discovered in the contract documents resulting in a change order in the amount of $189,300. Additionally, the splitting of Phase 2 into two phases resulted in a change order in the amount of $88,658. The current cost estimate is shown in Table 3.
