Solicitation 36C25218B0524 Amendment 00002 Project 695-18-106 QUESTIONS AND RESPONSES Repair Road Surface Bldg 20 and Various Areas Milwaukee VAMC

Q1. The plans show locations where sidewalk is to remain and the curb adjacent to the sidewalk is being replaced. Curb can’t be removed without replacing sidewalk because the sidewalk will be undermined. Should the sidewalks be replaced where they are directly behind curbs that are being replaced?

Response: See Drawing Revisions. Sidewalks to be replaced as shown.

Q2. Both lots 2 and 3 appear to be deteriorated beyond the point where they can be milled and overlaid. If they can’t pass a proof roll after milling, will the VA consider regrading and repaving with binder and topcoat?

Response: No – Proof rolling will not be required for milled asphalt. See response to Question 9.

Q3. What are the current elevations of lots 2 and 3? There is no way of knowing how much asphalt needs to be added to bring it to grade.

Response: See Drawing Revisions with existing grade contours added, and changes to “CS” plans’ keyed notes on asphalt thickness for intermediate courses.

Q4. When milling asphalt and replacing curb it’s not possible to install the curb to follow the contours of the existing asphalt. Should an 18” strip of asphalt be removed in front of all curbs, so the curbs can be installed with a slip machine and then patch the asphalt in front of the curbs?

Response: See Revised Drawing Detail 7/C-005.

Q5. The plans show Lincoln Drive being done in 3 phases. However, the road is too narrow to work on one side and keep the other lane open. Will it be possible to close this road while work is being done?

Response: See Drawing Revisions in CP-102. Work can be completed in 2 phases. Road must be opened Monday-Friday.

Q6. The plans show sections of sidewalk in Lot 10 to remain. However, the sidewalk is much steeper than allowed by code. Should the sidewalk be replaced and regraded to meet code requirements?

Response: See updated drawings for amended SOW to include all of the sidewalk. Replace sidewalk in current location, matching existing overall grade and slope except at H/C ramps.

Q7. The plans show 8” curb. However, 8” curb will cause damage to vehicles and will be significantly more expensive due to equipment costs and lost production. Will the VA consider installing 6” tall curbs?

Response: See Drawing Revisions, 6” curbs are standard.

Q8. C-002 Note 2 states all work shall be completed during off hours 1700 Friday to 0500 Monday.

a. Does that mean all parking lots and roads must be open by Monday 0500?

Response: Yes.

b. The work in the parking lots cannot be completed in one weekend so will the fence need to be erected and removed in that same timeframe and then reinstalled the next weekend?

Q9. After the asphalt milling is complete a proof-roll will be required to be able to provide a warranty for the new work. If the proof roll fails will the failed areas be repaired so they can be warrantied?

Response: Proof rolling will not be required for milled asphalt. In lieu of pavement warranty, provide paving to industry standard.

Q10. Are spoils considered contaminated? If so where will they need to be disposed?

Response: Refer to Earthwork specification 31 20 00 section 3.6D.

Q11. Is all work required to be surveyed before and after milling and after top coat is installed?

Response: Yes, refer to General Requirements specification 01 00 00 section 1.7 for photographic surveying requirements, refer to sheet C-002 General Notes for surveying requirements, and specification 02 21 13 section 3.3 for surveying requirements. Also see drawing revisions for changes to C-002 General Notes.

Q12. Detail 6 on C-005 call out for 7oz. geotextile fabric under all Typical sidewalks. This is not a typical requirement. Is geotextile fabric required under all new sidewalks as indicated?

Q13. Keynote 1 on CS-101 calls no build up or grading, just mill and resurface. Lot 10 does not currently meet ADA requirements therefore no contractor can legally resurface this lot without changing grades to meet code. Will the grades of lot 10 be changed to meet ADA requirements?

Response: VA Milwaukee has determined it is infeasible to modify the overall grade change across Lot 10 and its sidewalk. These spaces and lot do not meet ADA requirements and area not called out as such. See drawing revisions regarding leveling/buildup course.

Q14. Per 5 on C-004 flagmen are required to direct traffic, if the lot is completely fenced is a flagman still required? This would force the contractor to provide 24/7 traffic control.

Response: The lot is to be completely fenced. A flagman is not necessary at all times.

Q15. Detail 5 on C-004 refers to work zones. This detail cannot be achieved on Lincoln Drive. Will an alternate work zone plan for one lane work on Lincoln Drive be provided?

Response: See Drawing Revisions for Updated Work Zone.

Q16. CD-101 note 5 states demo storm inlet but none of the plans call out to replace the inlet or repair the structure. Will a drawing be provided to show how they are to be replaced?

Response: See Revised Drawing Detail 7/C-005.

Q17. The plans show construction fencing posts driven into the ground at pervious surfaces. Fences are not going to be up for extended periods of time. Can it be considered means and methods for the contractor to determine whether to support the fence with steel surface stands or driven posts?

Response: Detail 1A/C-005 shows two types of fences. Use fence on stands.

Q18. Work phasing note 2 of drawing C-002 depicted “WORK SHALL BE COMPLETED ON WEEKENDS, 1700 HRS FRIDAY THROUGH 0500 MONDAY”. Are we to perform entire project during weekends? Please clarify the working hours.

Response: Yes. Time window for working hours are from 5:00PM Friday through 5:00AM Monday.

Q19. On drawing CS-101, KN 4 indicates a total of 41 handicap parking stalls. Please confirm no standard parking is to be in Lot 10.

Response: Confirmed.

Q20. Drawing CS-103, KN 4 indicates a total of 7 handicap stalls. Please advise if Sign Posts are required (8/C-004).

Response: Provide signs per 8/C-004.

Q21. Drawing CS-104, during the site visit, it was noted that there are access controls to enter/exit the parking area. Please advise if the concrete island and controls are to remain.

Response: Yes. Concrete island and controls are to remain.
