Questions Answers

1 There is no pay item listed for Roadway Excavation in the

Summary of Quantities Sheets of the plans yet there is a detail for

Roadway Excavation on Sheet A9 of the plans as well as tabs in the Grading Summary on Sheet B3 of the plans for Roadway

Excavation in the quantity of 12,957 CY. Is Roadway Excavation incidental to an item and I am missing the note or is it missing from the Summary of Quantities/Bid Items?

We are paying for embankment construction only.

2 On the Sam.gov solicitation it lists construction from November

2024–August 2025, but the SCRs say the expected NTP is

12/13/24 with the period of performance ending 2/12/26. Am I correct in assuming that the SCRs would govern here?

See amendment A001 dated 10/07/24

3 In the SCR for the Cement Treated Aggregate Course it says, "At the option of the contractor, the existing surfacing and aggregate base may be salvaged, processed, and reused to reduce the quantity of imported crushed aggregate." Wouldn't any imported aggregate be paid in the Roadway Aggregate that has a quantity of

28,500 tons?

See pay item 30703-0000

1 Could you please clarify the reasoning behind the decision to install plowable markers on this roadway?

See FP-14 Section-634, plan sheet V22, Pavement Markings

2 What are the specific reasons for requiring epoxy adhesive for the placement of these markers? TxDOT does not have an epoxy adhesive that meets the projects specifications. The standard practice in Texas involves using bituminous adhesive for markers

See FP-14 Section-634.10 on asphalt surfaces, and regular or flexible adhesive is typically utilized for the placement of raised markers. Will these standard practices be accepted for this project?
