About this file
Addendum 1 for the Highway 9 Sidewalk Improvements project was issued by the Town of Frisco on April 16, 2024, providing clarifications and responses to contractor questions about the project. The document addresses various technical and procedural aspects of the sidewalk improvement project, including lane closure policies, excavation requirements, material disposal, and federal regulation compliance. Key clarifications include allowing turn lane closures in accordance with CDOT guidelines, reducing over-excavation requirements from 3' to 1', specifying that the town will not accept concrete or asphalt (which must be hauled to a disposal site), and confirming that federal regulations like Certified Payrolls and Buy America requirements are mandatory.
The addendum provides additional details about project specifications, such as allowing multiple retaining wall suppliers including Redi-Rock, Big Block, Stone Strong, and Recon Wall Systems, and specifying that only a small portion (5 square yards) of an existing gravel footpath will be removed to accommodate the new sidewalk. Contractors can request CAD files by emailing the Public Works Director, and while federal regulations like Davis Bacon Wages are required, Disadvantaged Business Enterprise (DBE) and On-the-Job Training (OJT) are not part of the project requirements. The document indicates that pedestrian flaggers are not mandatory, but pedestrian signage and detours must be installed by the contractor.

Response: Pedestrian flaggers are not required on the project. Pedestrian signage and detours are required to be installed by contractor.
Question 3. What are the shoring requirements?
Response: Any shoring costs shall be included in the retaining wall bid item (504-03500).

The upper pedestrian path may be closed, remove, and replaced if required for temporary slopes, in order to minimize shoring.
