Answer: All piles will be driven to minimum tip elevation (South Abutment - 5466.785, North

Abutment- 5466.5) and reach bearing capacity as well. Then filled with Class A(AE) structural concrete. Please see sheet 10 of 57 that shown the abutment elevations (South Abutment

-5579.785, North Abutment- 5579.50) and the pile being 9" into the abutment from these elevations(Sheet 12 of 57). This is a good volume to use for structural concrete. Air is required in all structural concrete mixes. Please see

Table 552-2 of the FP14. It requires 4.5-7.5 percent.

Re: Tie Rod, Page 17 of 57

Question: The Pile Caps per design are sloping to both sides of Centerline. Our Pre-cast Supplier has noticed that it is not feasible to thread the

Tie Rod through the girders as designed. Please provide Clarification.

Answer: We have a history of installing girders that are tied together with these tie rods, on a normal crown, with no issues during installation.

If there was any issues it was not brought to our attention and the Contractor resolved it with the manufacture during installation.

Re: Keyway Grout Detail - Page 18 of 57

Question: Drawing Typical Section : Due to

Design of the Cap , the bridge slopes each direction from centerline. Our Pre-cast Supplier has laid out the drawings and determined that between Girder D and Girder E, the bottom of the

Girders will have no space between the girders and the Joint at the top will be 7/8" wide. The

Backer Rod will have to 1 3/4" wide and the grout key 1 3/8 " . Will this be acceptable?

Answer: This is acceptable.

2. All other terms and conditions remain unchanged.
