No building 21 in our scope.

Question not answerable.

ref Building 1

5. Several areas on this building are showing construction fencing required where it would completely isolate the area from any traffic at all from pedestrians. In those same areas they are calling for complete scaffolding as well. If we are using fences to keep people away from any construction, are we also needing scaffolding there?

Fencing & protective scaffolding required.

Scaffolding with protective assembly to protect against falling debris. Scaffolding is required to have physical enclosure and locked (plywood or similar) 8’ from the ground to prevent unauthorized access, at the point of scaffold entry. All scaffolding shall be OSHA and VA safety spec compliant. All scaffolding requires identification tag and daily inspection from the contractors CP.

6. In the middle of Building 1 there is an upper shingle area where they have called for Scaffolding and overhead protection for a sidewalk. This is a very small area of walkway, are we able to fence this area off instead of using scaffolding in this area? It is a construction zone, and they didn’t call out any fencing in that area that I could see.

G1003 requires fence & multiple scaffolding types, including off hours work. Adhere to contract.

7. The specs call for a shingle that is no longer available. I will enclose a discontinuation letter from GAF. Same for all shingle areas.

ref Building 2

8. Area of construction has one door to the Fencing & protective scaffolding required.

building on that side. Is it possible since they are already calling for fencing to just block off that one door and not have to use scaffolding and overhead protection there?

Scaffolding with protective assembly to protect against falling debris. Scaffolding is required to have physical enclosure and locked (plywood or similar) 8’ from the ground to prevent unauthorized access, at the point of scaffold entry. All scaffolding shall be OSHA and VA safety spec compliant. All scaffolding requires identification tag and daily inspection from the contractors CP.

9. On 2 sections of guttering, they call for removing and replacing yet the roofing above those areas says existing roof to remain. Please clarify.

Existing roofing to remain.

Remove and replace gutter assembly where indicated.

ref Building 48

10. Like other buildings. Several areas where they are asking for scaffolding where the nearest walkway is extremely far away from the construction area.

Can we avoid using scaffolding in these areas?

No.

Redundant Safety required “Extremely far away” is subjective. Fencing and scaffolding as shown is required. See above related questions and answers.

11. There are 2 doors within construction zone that could be blocked off while we work as they already included fencing in those areas. Can we block those doors off during construction?

No. Follow VA Designed Safety Plan.

Maintain the egress/ingress as VA designed.

12. They call to remove fascia in several areas, but they don’t specify to replace fascia on any areas for this building.

Areas of removal assembly shall be replaced with new material. Material shall be like and kind (color, profile, size, material, performance).

ref Building 50

13. This building only has 1 entrance. All other construction areas are extremely far from any walkways. Can we use scaffolding w/ overhead protection just a certain distance in either direction of that entrance? Fencing is called for surrounding the entire area so that should suffice.

Follow VA Design Safety Plan, fencing and scaffolding required.

See previous related answers.

14. They call to remove fascia in several areas, but they don’t specify to replace fascia on any areas for this building.

Areas of removal assembly shall be replaced with new material. Material shall ref Building 51

15. Would it be possible to close off the No door in the courtyard on south side of the building?

16. Remaining scaffolding doesn’t appear necessary if we use scaffolding with overhead protection on the 2 remaining entries.

Follow VA Design Safety Plan

17. They call to remove fascia in several areas, but they don’t specify to replace fascia on any areas for this building.

Areas of removal assembly shall be replaced with new material. Material shall ref Buildings 37

18. Building 37- There are no walkways or entry points on ¾ of the building. Are we allowed to just use scaffolding where we need to have overhead protection?

Areas of removal assembly shall be replaced with new material.

Pg. G1008 ref Building 69

19. Building 69- This is basically a small shed. We would have it completed in less than a day. Can we erect construction fencing and do away with scaffolding?

B69 can be closed for 1 calendar day.

Closed defined as the VA will not access the building that day. If contractor can perform ALL work required within 1 calendar day they may do so without scaffolding system. B69 ONLY.

ref Building 95

20. Building 95- They are calling for an AC unit to be moved and all lines to be moved to keep unit in place. I can locate an AC company if you would like for this.

This question is for a GC to answer rto their sub.

ALL Prime contractors submitting proposals shall adhere to plans and specs.

21. Building 95- They mention in the prints on Section @B95 Link new iso board and roofing however on Building 95 demolition page it says everything is remaining except the small roof in the back. Need Clarification please.

Adhere to the plan and specifications. B95 and adjacent link are partial roof replacements.

22. Building 95- Shingle portion they say that a section to left and right of new shingle section but the section to the left is just a tiny bit before reaching a wall.

We just need clarification on where to start and stop.

Conduct work per plan and specification.

ref Building 100

23. They call for scaffolding on all 4 sides.

There are doors on the 2 ends. Can we do away with scaffolding on other 2

North and south doors require overhead scaffold protection per plan. NO debris shall leave the fenced area. Construction fence sides? limits shall not be extended . Remaining scaffolding at building 100 may be eliminated.

24. Matching exact color may be impossible due to age of the building and weather conditions.

Match as close as reasonable per the manufacture. Existing product is beige, product colors are on file from Morton Buildings at Sherwin Williams locations.

25. According to SECTION 01 35 26

SAFETY REQUIREMENTS Part 1.26 and the Final Drawings, scaffolding and overhead protection WILL BE REQUIRED in those areas. We just wanted to confirm this requirement for bidding purposes and project planning.

Yes scaffolding has multiple safety purposes as designed and is required.

Scaffolding is not optional. Contractor required to follow OSHA and VA safety spec, including protecting existing conditions from contractor means and methods. Plans and specifications require the minimum precautions. Contractor shall include additional precautions per their work sequence, means and methods. Fall protection according to the VA safety specification is required even with the designed scaffolding system.

26. According to SECTION 07 31 13 ASPHALT SHINGLES Part 1.7 and 2.2 the Specs call for the following:

B. Manufacturer's Warranty: Warrant asphalt shingles against material and manufacturing defects.

1. Material Warranty Period: 30 years.

No substitutions.

2. Wind-Speed Warranty Period: Resist wind speeds up to 180 km/h (110 mph) for 15 years.

3. Algae-Resistance Warranty Period:

No discoloration for 15 years.

A. Asphalt Shingles: To match existing on Historic Buildings (Three (3) Tab style) - GAF Weather Max 30-GR Charcoal, no substitutes allowed. 1.

ASTM D3462/D3462M and ASTM D3018/D3018M, Type I, self-sealing.

2. ASTM D3161/D3161M, Class D or F wind resistant.

3. UL 790 Class A fire resistance.

4. Minimum Weight: 10.3 kg/sq. m (210 lbs./100 sq. ft.).

5. Timberline or equivalent, basis of design.

Allowable alternate product:

GAF Royal Sovereign Color to match existing shingles.

Color sample required.

60 mph wind warranty noted.

3 TAB design required.

Existing shingle color charcoal.

Architectural shingles are not approved.

Disregard any previous mention of architectural shingle or laminated shingle products.

We would like to note that the GAF Weather Max 30-GR shingles have only an 80mph wind rating (please see attached flyer) and is a 3-tab shingle basis of design. The Timberline basis of design is a architectural shingle and not in the same category as the Weather Max design. This was referenced in the spec, and we just wanted to note the difference.

27. According to the drawings, building 100 is supposed to have a new standing seam metal roof installed, but after the site visit and reviewing the specs, it appears that building 100 is to have matching corrugated metal panels to match existing installed. Could we please get some clarification on this?

Agreed. New overhang roof is to be corrugated metal. Existing product is a Morton building product. On the underside of the sheet metal states “108 Midwest Morton RCK MOB’L 9-13 83”. Match as close as reasonable. Morton confirmed their product has remained unchanged since the 80’s.

28. What is the workmanship warranty period for the repairs on the asphalt shingles? The warranty is stated for the materials, and we want to verify the workmanship warranty for the project is the standard one year after final inspection.

Prime vendor shall provide a 1 year workmanship warranty from final acceptance of contract. There will be 1 acceptance date for the entire project. All manufacture material warranty shall apply.

29. On the EPDM roofing sections, is there a specific manufacturer's warranty that are you are expecting or is the standard 20 year manufacturer warranty sufficient? Will each building with a new EPDM roof require a separate warranty per each roof?

20 year material warranty from date of project acceptance is acceptable.

30. Roofing Suppliers are stating the Weather Max shingles are no longer being manufactured and are discontinued. Is there an approved alternative that will meet specs?

See question 26.
