Q8. If additional drains are added, landscape repairs may be extensive. Are these to be included in this proposal? Will seed or sod be required?

R8. No additional drain are to be added but contractor to protect the existing inlet and pipe. Seed and sod will be required up to 5 feet on the area where the drainage slope need grading to provide proper drainage.

Q9. Water pooling could be seen outside of the track border in multiple locations, are these Areas to be re-graded or have an added drain as well?

R9. The outside of the track border that are more than 5 feet from the track is not part of the project.

Q10. Will electronic copies of proposals be accepted due to the circumstances of COVID-19?

R10. No; Please refer to Section Section L “instructions to offerors”, para. L-2.

Q11. Cross slope is provided as 1% for slope of crown or 1/16” from centerline to face of header curb. Is that in fact the desired cross slope?

R11. Required a Crown running truck surface with a minimum of 1%, maximum of 2% slope of leveling course as allowed by track construction rules shall be maintained in the leveling course for Proper drainage of track surface area.

Q11. What is the desired longitudinal slope (max/min)?

R11. Contractor to fallow the preexisting longitudinal slope of the running Track keeping the optimum longitudinal Slope as allowed by running track construction rules.

Q12. What is the min. thickness of rubberized surface?

R12. The min thickness of the rubberized surface is 13 mm or 0.5 inch.

Q13. What gradation of HMAC is desired, C, D, F or other. Please specify if dense or open graded course is required.

R13. HMAC is desired is type D open Graded. Also, contractor is required to look at manufacturing specification for the construction of the running track that will provide the optimum gradation.

Q14. Please specify type of base material required.

R14. Base material by job mix formula TxDot 247, Type A grade 1-2. Contractor is required to look at manufacturing specification for the construction of the running track that will provide the optimum base material as indicated in the GENERAL NOTES project drawing sheet 102.

Q15. Please specify the rate of application of lime in the stabilized subgrade.

R15. Lime should be by job mix probably between 4-6% target ph is around 12.4, compact to 95% max density.

Q16. Is the concrete curb non-reinforced?

R16. Curb probably doesn't need re-enforcement in the 2' deep curbs, but if used 3 #3 bars 6" O.C.

Longitudinally and #3 36" O.C Vertical.

Q17. What is the depth of the new concrete curb? Existing is noted as 2’ deep.

R17. Depth of the new concrete curb is 2’ deep.

Q18. The existing width of the track is noted as 15’ 3” yet the new track is to be 15’. If Option 2 is not awarded how much of a transition zone is needed for the transition from 15’ 3” to 15’?

R18. Old and new track should be 15'3". The contractor to keep the same with as the old track which is approximately 15'3" width as in drawing sheet C-101 D1 TYP. TRACK SECTION.

Q19. There are three existing 6” concrete maintenance crossings. Sheet C-102 only illustrates one but there is no reference to replacing one, two if base bid is awarded only or all three if Base and Option 1 Is awarded. If required, please provide specifications. If the concrete maintenance crossings are to remain, would it be the designer’s intent to match existing grade of the pads and make the track grade fit as best as possible?

R19. Yes the designer intent is to match the existing grade of the pads and make the track grade fit as best as possible.

Q20. Are we to treat the runoff from the existing drainage ditch on the southeast and northwest sides of the base bid track? If not, are we to install a culvert?

R20. Contractor is to grade up to 5’ on the outside and inside edge of the track as well to properly slope the area for a good drainage system to the existing inlet in the area that require proper drainage flow.
