East Shade Shelter Shoreline Stabilization

The East Shade Shelters Shoreline Stabilization Project is a public infrastructure contract solicited by the Cherry Creek Basin Water Quality Authority (CCBWQA) and Colorado Parks & Wildlife (CPW), with jurisdictional involvement from Arapahoe County and Aurora City. The primary procurement objective is to reduce phosphorus and contaminant discharge into Cherry Creek Reservoir through comprehensive shoreline stabilization methods, covering approximately 0.3 acres and 400 linear feet of shoreline. Deliverables include bank stabilization, erosion control, pedestrian access management, and environmental restoration using techniques such as soil riprap with live stakes, fieldstone installation, boulder walls, crusher fines trails, and massive rail fencing. The project requires contractors to provide all labor, materials, equipment, and services to complete shoreline stabilization work, with a construction timeline of 120 consecutive calendar days from the Notice to Proceed. Key procurement dates include a mandatory pre-bid conference on September 18th, 2024, at the Cherry Creek State Park East Boat Ramp Parking Lot, with electronic bids due on October 21st, 2024, at 10:00 AM through the Rocky Mountain E-Purchasing website. Contractors must submit a 5% bid security, performance bonds, detailed documentation including construction schedules, traffic control plans, and environmental compliance documentation.

The contract does not explicitly mention set-aside designations or restrictions for disadvantaged enterprises. The United States Army Corps of Engineers (USACE) owns the property and will review improvements through a 408 permit. The estimated total project cost is $518,831, which includes a 30% contingency of $119,730, with the construction cost range estimated between $572,604.00 and $791,000.00. Funding will be jointly provided by CCBWQA and CPW, with both organizations expected to maintain the site after project completion. The project involves multiple line items including clearing and grubbing, tree and vegetation removal, excavation, grading, staircase construction, riprap installation, boulder walls, fencing, and revegetation efforts. Liquidated damages are set at $300 per day for failure to complete the project within the specified timeframe. The site is located at Cherry Creek State Park in Arapahoe County, Colorado, with work hours restricted from 5 a.m. to 10 p.m., and the East Shade Shelter parking lot can only be closed prior to May 1, 2025.
