The City of Stillwater is seeking bids to rebuild and improve the 10th Avenue and Main Street mini-roundabout in Oklahoma.
- **Government buyer:** City of Stillwater, Oklahoma; the attachment summaries identify the Engineering Department, Office of the City Clerk, and Community Development.
- **Scope:** Roadway excavation, pavement removal and replacement, concrete work, traffic control, signs, markings, lighting, landscaping, irrigation, hardscaping, demolition, and stamped-concrete rehabilitation. Plans also call for stone planter edging, sculpture lighting, utility coordination, and site restoration.
- **Named manufacturers and vendors:** **Rain Bird** (irrigation equipment), **RAB** (sculpture uplights and mounting post), **Wilkins** (backflow preventer), **Mirafi** (separator fabric reference), and **Bluebird Stone** (Navajo stone edging). The manufacturer of the MS-200 and MS-127 solar lights is not identified; approved equals are allowed for the specified lighting.
- **Key quantities and specifications:** 250 SY of separator fabric (Mirafi 160 or equivalent); 16 MS-200 solar lights in the bid invitation (the project manual lists 4); 20 MS-127 flush-mounted roundabout lights; 24 SF of ODOT Type C tactile warning devices; and MUTCD yield, roundabout, and pedestrian signs. The plans specify 6 RAB LFLED8NA uplights, Rain Bird irrigation components, and a Wilkins 975XL2 backflow preventer.
- **Other notable requirements:** Protect existing utilities and the bronze sculpture, maintain access and traffic, provide approved traffic-control and stormwater plans, and perform at least 15% of the work with the prime contractor's own forces. The plans include a separately priced alternate for full replacement of the 4-inch stamped-concrete apron and mountable curb.
- **Quantity discrepancy:** The bid invitation and project manual differ on the MS-200 light quantity (16 versus 4) and street name sign quantity (4 versus 16); bidders should confirm the controlling schedule.
