About this file
This is Addendum #1 to an Invitation to Bid issued by the City of St. Marys for the Intersection Improvements Project, modifying the original bid documents. The project involves construction improvements at an existing intersection along St. Marys Road (stations 42+82.58 to 64+16.12), including widening to accommodate right and left turn lanes for the new Esplanade Boulevard, pavement removal, milling and resurfacing, pavement overbuild for slope correction, modifications to existing drainage structures, installation of new drainage structures and piping, re-grading of roadside swales, roadway striping and signage, sodding and grassing, erosion and sedimentation control, and maintenance of traffic along approximately 0.4 miles of St. Marys Road between Interstate 95 and Osprey Cove Subdivision. The bid opening date remains October 30th, 2025, at 2:00 PM. This addendum must be signed, dated, and included in all bid submittals.
The addendum establishes specific material and construction requirements for bidders. Roadway base material must consist of crusher run granite from a GDOT-approved quarry, with recycled concrete aggregate and lime rock explicitly prohibited. Existing pavement thickness data from six cores indicates asphalt ranging from 6.5 to 8.75 inches, underlying concrete from 5 to 6.75 inches, and lime rock from 7 to 10 inches. Contractors must maintain one travel lane in each direction open at all times and comply with GDOT and MUTCD traffic control standards. Strict adherence to the approved Land Disturbance Activity permit is required, with any dewatering plans requiring coordination with the Engineer of Record. The City prefers precast drainage structures; site-built units require design calculations and material testing demonstrating GDOT compliance. No laydown area exists outside the right-of-way, and project CAD files are unavailable, though unlocked PDF files are provided to bidders.
