1. Section B Page 3 of the solicitation states that 1,722,661 L.F. of joints are to be repaired, but the statement of work calls out 380,000 L.F. Please clarify.

ANSWER: See Amendment 0002 for correction to CLIN 0001 extended description.

2. The plans and statement of work call out 100 S.Y. of “Corner Break Spalls”. Not all spall locations will be “Corner Breaks”. Is the 100 S.Y. the total quantity of partial depth spall repair to be included in the bid. Please clarify.

ANSWER: Yes, per statement of work (SOW) paragraph1.3.2

3. Please provide the locations of the “Secure Zone” in relationship to the areas of work outlined on the “Area of Work” plan.

ANSWER: All work is in the secure zone.

4. Do you have the approximate quantities of spall repairs and crack repairs separated by work areas?

ANSWER: No.

5. Section 1.5 “Phasing” in the “Statement of Work” appears to have nothing to do with this project. Is there any minimum phasing requirements on this job, other than what is called out in Section 1.6.3 “Work Planning”? Please provide phasing plan.

ANSWER: SOW paragraphs 1.5.1, 1.5.2 and 1.5.3 deleted. Paragraph 1.5 Phasing changed to read RESERVED. Phasing plan to be developed by contractor and airfield management after award of contract.

6. Statement of Work Section 1.12.4 indicates that joint seal work is to be performed on the runway, but no work on runways is indicated on plans. Please Clarify.

ANSWER: No Runway work required. SOW paragraph 1.12.4 changed to RESERVED.

7. Where is the contractor’s storage/laydown yard located?

ANSWER: Storage/laydown area will be determined at precon.

8. Since the owners did not provide plans showing the actual joints, how is the contractor to provide “As-builts”. Please Clarify.

ANSWER: See solicitation attachment 4 drawings (Seal Apron Joints Details dated 10 Aug 77 and Area of Work dated 7 Jul 15).

9. Section 32 01 19, “Field Molded Sealants” Subsections 1.2.1 and 1.2.2 call out that joint sealant will be paid and measured by the lineal foot, but the bid documents are lump sum. Please Clarify.

ANSWER: Contractor is to generate his price/costs and annotate the total in schedule B. Payment will be based on percentage of work completed.

10. Bid proposal document Sheet 29 of 33 Subsection 1(b) calls out to insert proposed unit prices for contract lines 0001 and 0002. There is no contract line 0002, nor are there unit prices for the different work items. Please clarify.

Answer: See amendment 0002 for corrections.

11. Section 32 01 19 “Field Molded Sealants” Subsection 2.1 calls out 4 different types of liquid joint sealants ie: Hotpour, 2-Component Hand Mix, 2-Component Machine-Mix, and Silicone and Section 32 13 73 adds compression seal. Please clarify what type of sealant you want. We suggest using Liquid Silicone Joint Sealant for its ability to conform to irregular joints and jet fuel resistance, as well as, the fact that no manufacturer makes 200 E 2-component sealant any longer and the hot pour sealant specified is not jet fuel resistant.

ANSWER: Sealant that meets UFGS and Air Force construction standards.

12. Section 01 22 00 “Measurement and Payment” do not appear to even be for this project. Please clarify.

ANSWER: Specificatin 01 22 00 removed.

ANSWER: Specification 03 01 26.71 deleted.

16. Section 32 01 28 “Partial Depth Patching of Rigid Pavements”. This specification section is confusing and convoluted. Please clarify the following:

a. Do you want a proprietary cementitous repair product to be used for all partial depth patches. Ie. A pre-bagged repair product.

ANSWER: Use product that meets UFGS and Air Force construction standards.

b. If an approved pre-bagged proprietary repair material is used, will the requirements for mix designs, cement testing, aggregate testing, alkali silica reactivity testing etc. be necessary.

ANSWER: Yes, if required by UFGS or Air Force construction standards.

c. Do you want a bonding agent applied or are we to follow manufacturers recommendations?

ANSWER: Use product that meets UFGS, Air Force construction standards and manufacturers.

d. Subsection 2.1.9.1 compression strength states “A minimum of 3500 PSI is required at 3 hours and 1 day of age. Which is it 3 hours or 1 day? 3500 PSI in 3 hours is an extremely high strength considering the specification for Portland cement concrete calls out for 4500 psi in 28 days. Please clarify.

ANSWER: 27 hours.

e. What are the test ages for test cylinders made for proprietary repair products? See section 3.4.2.

ANSWER: Follow UFGS and Air Force construction standards.

f. Subsection 1.1.1.2 calls out that quantities of partial depths patches will be paid by the square foot but there are no unit prices in bid documents.

17. Section 32 13 11 “Concrete Pavement for Airfield and Other Heavy Duty Pavements”. Is there any full depth concrete paving on this project or was this specification also added by accident. Please clarify.

ANSWER: There is no full depth concrete paving in this project however, specification is still applicable.

18. Section 32 13 73 “Compression Joint Seal for Concrete Pavement”. Is there any compression seal to be installed on this project. Please clarify.

ANSWER: Install sealant that meets UFGS and Air Force construction standards.

19. Plan detail sheet dated August 10, 1977 the “Typical Expansion Joint Detail” and “Typical Contraction Joint Detail” and “Typical Construction Joint Detail” shown on this plan are contrary to any current sealant manufactures recommendations.

a. You cannot install new sealant over old sealant, no manufacture will warranty this installation.

b. All joints should have a foam backer rod installed to create the proper joint geometry and depth dimensions.

c. Note 1 on this sheet indicates a depth to width ratio of 1 to 1 1/3. This is completely wrong and needs to follow manufactures recommendations once you choose the sealant you want from the 5 choices outlined in the specification.

d. Note 2 on this sheet again calls out that you may install new sealant over the old sealant which is incorrect.

e. Note 5 on this sheet makes no sense. Please clarify.

f. Notes 7, 8, and 9 call out “Phases”, but there is no phasing plan. Please provide phasing plan.

ANSWER 19 a-f: Drawing dated 1977-08-10 is made available to familiarize contractors with joint geometry. Follow applicable UFGS and Air Force construction standards when installing joint seal

Spec Section 32-01-28 Partial Depth Patching of Ridged Pavements Subsection 2.1.9 through 2.1.9.6 “Proprietary Cementitious Products” call out specific test methods and test results that the Proprietary Cementitious Repair Product must meet. We have looked at 10 different Pre Bagged Repair Products that are widely used for airfield spall repair, none of these materials show the exact test results or test methods that the specifications require. Do you have a Proprietary Cementitious Repair Material that you based these specifications upon? Please clarify.

ANSWER: No. Use product that meets UFGS and Air Force construction standards.

22. Can we have clarification on a couple pieces of conflicting information on the proposal form? Item No 0001 - Indicates there is approximately 1,722,661 lf of airfield joint sealant repair.
