No, please bid according to the contract docs. (2) Is there any way to itemize the Helical Piers for the 40’ bridge as its own bid item so it can be measured and paid by the LF? This will help remedy any source of contention down the road since the required depths are unknown to meet the torque specs. A new bid item will be added for the helical piers. (3) Can the 12” caissons also be broken out as its own separate item just in case we need to go deeper than expected? A new bid item will be added for the 12” caissons. (4) There doesn’t seem to be a toe wall associated with the box culvert. Is this correct? The toe wall is only required at the wingwalls, see detail D on sheet S04. (5) It is understood that the city will be providing construction surveying. Will the city also be doing the certified as-builts that is needed to meet the floodplain requirements? Yes, the City will be doing the as-built surveying to meet floodplain requirements. (6) To clarify, the bid item “Precast Concrete Underpass System” is just for the material of the precast concrete and item “Precast Concrete Erection” includes the setting of this system. Is this correct? Correct, delivery of the materials should be considered incidental to either bid item. (7) Please clarify what is all in the bid item, “Concrete Class D (Wall).” Other than the bridge abutments (which is way less than 67 CY), I don’t see any structural concrete on the plans. The Concrete Class D (Wall) quantity should be zero. The Reinforcing Steel item quantity should also be zero. The wingwalls are included in the Precast Concrete Underpass System item. Topping concrete within the underpass will be included in the 10’ Concrete Bikeway item (discussed below in #8). Concrete and reinforcing for bridge rail curbs should be considered a part of the Bridge Rail Type 10 (Special) item. Addendum 1 – 7664 Fossil Creek Trail Underpass at Trilby Road Page 4 of 12 (8) Are the bridge abutments incidental to the bridge bid items or they included in the “Concrete Class D (Wall)?” A new bid item will be added for the bridge abutments. (9) In regards to the cast in place concrete topping inside the box, in what bid item is this getting paid? The concrete topping inside the box shall match the 10’ Concrete Bikeway and that quantity is included with that item. (10) On Sheet C13, there is a reference to a Bentonite Blanket. Where does this get paid and what are the specs? The Bentonite Blanket will not be required. (11) Is a 404 permit required for this project? Yes, the Owner has acquired a Nationwide Permit No. 14 for the project. The CONTRACTOR is responsible for 100% compliance of all work accomplished in accordance with the terms and conditions of the nationwide permit. (12) Does asphalt need Flyash? No (13) Will CDOT be reviewing and approving the bridge drawings? No Addendum 1 – 7664 Fossil Creek Trail Underpass at Trilby Road Page 5 of 12 EXHIBIT 3 – DESCRIPTION OF REVISIONS I.
