Question #1: Bid Item Line A0460 SUPERPAVE PAVEMENT calls for Liquid asphalt PG70-10 to be used in the mix. PG70-10 is not available in the area of the project. TxDOT specifies PG64-22 and PG70-22.

Would the engineer consider changing asphalt type?

Response: Yes, the asphalt binder should be a PG 70-22. Refer to Amendment 1 for updated information.

Questions #2: What are the liquidated damages for the project?

Response: Please refer to FP-03, 108.04 Failure to Complete Work on Time.

Question #3: Appendix D contains a sample Subcontracting Plan with blanks for % of total planned subcontracting dollars to various types of concerns: (SB, SDB, WOSB, HUB,VET/SDVET, LB)

Does the contract establish any goal for subcontracting with these types of subcontractors?

Response: No, they are tracked goals.

Question #4: It is noted that Section 623 of the specifications has modified General Labor to include two additional classifications. There is a pay item for the Surveying Services, but not for Office Technical Services. Are we are required to provide a Design Engineer by this specification, and if so how will it be paid?

Response: A pay item to include technical services will be included in a forthcoming Amendment 1.

Question #5: Is a field office or residential housing; described under Section 637 of the FP-03 specifications, required for this project?

Response: This does not apply. There is no 637 pay item.

Question#6: Is a field office or residential housing; described under Section 637 of the FP-03 specifications, required for this project?

Response: This does not apply. There is no 637 pay item.

Question #7: For the Subexcavation Item, the detail on sheet F1 of the plans indicates to ‘Backfill with material according to Section 204.’ However section 204 has many different kinds of materials shown under the materials list. What material exactly is intended for use in the backfill for the Subexcavation?

Response: Any material that meets requirements in FP-03 Section 703.06 may be used for this item.

Also minor hot asphalt concrete meeting FP-03 Section 404 may be used.

Question #8: We have a calibrated inertial profiler. What type of roughness index is required, 3 or 4?

Response: It is a Type III and V according the SCRs under Section 401.01

Question #9: Field density @1 ½” lift will be difficult to achieve with a 75 gyration requirement in the super pave mix. Can the gyration requirement be lowered to 50 gyrations in the super pave mix?

Response: No, the Superpave mix shall be a 75 gyration requirement.

Question #10: If 75 gyrations is still required may we lay a single 3” lift instead of 2 – 1 ½” lifts?

Response: No, 2-1 ½” will be required.
