RESPONSE TO QUESTIONS RECEIVED AS OF JULY 15, 2024:

1. Question: Does the Invitation to Bid package have a breakdown of quantities for each individual road?

Response: No. The quantities provided on the Bid Form in Section 5 are for all the roads combined within the project scope. Sketches SK-1 to SK-6 show the approximate length of each road section. SK-18 shows the four (4) roads that are proposed to be reclaimed and the section view lists the approximate width of each road segment. A separate document has been attached which has a breakdown of the proposed bid items for each road and the approximate quantities for each road segment.

2. Question: Can you confirm that the Cape Cod berm must be installed with both the binder and surface courses of asphalt pavement?

Response: Yes. Bituminous concrete berm is required with the installation of the binder course. Since the paving operations are a two (2) step process, with a 6-month minimum waiting period, all drainage needs to be controlled for the entire waiting period to prevent runoff and erosion to adjacent properties.

3. Question: Can you confirm that the pavement depths for the driveways shall match the roadways, 2 ½” binder course and 1 ½” surface course?

Response: Bid Item No. 7 Asphalt Driveway Apron (Handwork) includes pavement based on a 2.5-inch binder course and a 1.5-inch surface course. All driveway binder course installation shall be installed monolithically with the roadway installation. No cold joint is allowed.

4. Question: Can you confirm that the asphalt pavement for the sidewalks must be installed in two lifts, i.e. 1 ½” binder course and 1 ½” surface course.

Response: The bituminous concrete sidewalk shall be installed in conformance with

RIDOT Specification Section 905 which states the asphalt can be installed in one or two lifts. The sidewalk can be installed in one 3-inch compacted layer but must be uniformly compacted to the required depth and density. Compaction shall be with a vibratory roller acceptable to the Owner. The Town prefers the sidewalk be installed in two equal lifts.
