Lost Canyon Ranch Open Space Roadway Maintenance and Parking Lots

The Town of Castle Rock, located in Douglas County, Colorado, is soliciting sealed bids for the Lost Canyon Ranch Open Space Roadway Maintenance and Parking Lots Construction project. The procurement involves comprehensive infrastructure improvements, including grading an existing dirt road, installing Class 6 roadbase, constructing retaining walls, implementing drainage improvements, and developing the first trailhead parking lot with concrete walks and stairs. The project includes a base bid and two alternate bid options: the Cattleman's Trailhead Parking Lot and the Willow Creek Accessible Trail. Bidders must attend a mandatory pre-bid conference on August 21, 2025, at 11:00 a.m., with sealed bids due by September 4, 2025, at 1:00 p.m. The town requires bidders to demonstrate previous experience with similar projects, with the prime contractor required to self-perform a minimum of 51% of the construction value. Evaluation criteria will consider factors beyond lowest price, including delivery time, warranties, and performance factors. The project has a substantial completion date of May 21, 2026, with final construction completion by June 4, 2026.

The procurement does not explicitly specify set-aside designations for disadvantaged enterprises, though the town gives preference to Colorado labor and materials when quality is equal. Bidders must provide a 5% bid guarantee, along with a Certificate of Insurance, Performance Bond, and Labor and Material Payment Bond. The project requires comprehensive documentation, including updated construction documents, as-built drawings, warranties, and O&M manuals. While specific budget ranges are not detailed, the bid forms include a comprehensive unit price schedule allowing for potential additions or deletions of bid items up to 25% of the original quantity. Contractors must obtain necessary permits and coordinate inspections with multiple agencies, including the Town of Castle Rock Building Department, Castle Rock Water TESC, and Public Works. The town reserves the right to cancel the invitation to bid, reject any bid, and adjust work quantities based on budgetary requirements, providing flexibility in the procurement process.
