Question Answer SOW Revision

Y/N If Revised; paragraph and page number

Specs call out cut material is 2,000 c.y. will there be a change order for anything more than that?

The anticipated amount of cut materail is 2,000 CY. Approximate square footage of excavation is 390,100 SF. Please be advised that this is only a best guess based on 2011 TNRIS LiDAR data, and is not based on ground survey data.

Yes Sec 01 11 00.10

Para 1.3.2.2

For the purposes of the scope of work it indicates 2,000 cubic yards of cut. Generally this does not sound like a great deal of grading but when considering the amount of surface area this is occurring over it is a much larger area. It is recommended that the square footage of area to receive grading be indicated rather than the cubic yards of actual cut to ensure those not in attendance at the site visit understand the significant area that is being graded.

Because of the age of existing joint sealant, it is uncertain how the existing sealant will fare through the diamond grinding process. Please provide a quantification for joint sealant replacement.

The 'old' section of the southern end of the West Runway has joint seal that is in poor condition. This is the section where the slabs measure 13' x 15'. It is extimated that 15,000 LF of joint seal will need replacing.

Yes Sec 01 11 00.10

Para 1.3.2.6

Section 01 11 00.10 Paragraph 1.3.2.6 requires Joint Seal Repair in the event the diamond grinding process causes damage to the existing joint seal. As discussed and observed at the site visit there is variation throughout the runway with the depth of the joint seal with some areas having joint seal already on top of the slab. As it was not possible to fully take off this condition during the site visit it is recommended that an allowance be accounted for in this bid. Will the government provide a linear footage of joint seal repair that the contractor should include in its bid?

The 'old' section of the southern end of the West Runway has joint seal that is in poor condition. This is the section where the slabs measure 13' x 15'. It is extimated that 15,000 LF of joint seal will need replacing.

Yes Sec 01 11 00.10

Para 1.3.2.6

What is considered damaged sealant?

Joint sealant will be considered damage when it meets the "High Severity" definition in the 2010 Airfield Concrete PCI Handbook. According to the Handbook, "Typical types of joint seal damage are (a) stripping of joint sealant, (b) extrusion of joint sealant, (c) weed growth, (d) hardening of the filler (oxidation), (e) loss of bond to the slab edges, and (f) lack or absence of sealant in the joint." High Severity is defined as, "Joint sealer is in generally poor condition over the entire surveyed section, with one or more of the above types of damage occurring to a severe degree. Sealant needs immediate replacement. Joint seal damage is at high severity if 10% or more of the joint sealer exceeds limiting criteria listed above, or if 10% or more of sealer is missing." The Airfield Manager and CE Pavements will be the responsible party for inspection and severity determination.

Yes Sec 01 11 00.10

Para 1.3.2.6

Because of the age of existing concrete, it is uncertain how these panels fare through the diamond grinding process. Please quantify the numbers of runway concrete panels to be replaced.

Per SOW Section 1.3.2.5 Slab Replacement, "it is anticipated that no more than 4 slabs will need replacement." To further clarify, it is assumed that 4 - 25ft by 25ft slabs will need to be replaced. Per SOW Section 1.3.2.4 Spall Repairs, "it is anticipated that no more than 50 square feet of pavement will need spall repairs."

Yes Sec 01 11 00.10

Para 1.3.2.5

Are we to grind just the 1/4” of the existing concrete even though we did see some panel that had moved 1/2” up or so? The grind machine will not adjust to those difference.

Each section of runway will have different requirements. Please reference attached Pavement Detail Map. Some areas of runway are at or below UFC minimums for slab thickness. In Section 4 (north end), do not remove an amount greater than 1/4 inch. In Section 8 (the northern end of the south end where slabs measure 13' x 15'), grinding may go to a depth no greater than 3/4 inch. In Section 10 (southern end of south end where slabs measure 25' x 25') grinding may not exceed 1/4 inch. Ensure transition from Section 8 to Section 10 is smooth, in accordance with Section 2.1.1.2 of Section 32 13 14.13 in the specifications.

Per SOW Section 1.3.2.4 Spall Repairs, "it is anticipated that no more than 50 square feet of pavement will need spall repairs."

Yes Sec 01 11 00.10

Para 1.3.2.5

The solicitation specifies a max grinding depth of ¼”. The amount of removal is determined by the existing profile of the concrete area to be ground. It will cut deeper in some areas, and shallower in others depending on the profile of the pavement. Will some areas ground deeper than ¼’ be acceptable?

Each section of runway will have different requirements. Please reference attached Pavement Detail Map. Some areas of runway are at or below UFC minimums for slab thickness. In Section 4 (north end), do not remove an amount greater than 1/4 inch. In Section 8 (the northern end of the south end where slabs measure 13' x 15'), grinding may go to a depth no greater than 3/4 inch. In Section 10 (southern end of south end where slabs measure 25' x 25') grinding may not exceed 1/4 inch.

Section 01 11 00.10 Paragraph 1.3.2.5 requires slab replacement in the event the diamond grinding process causes damage enough to warrant entire slab replacement. In this it states that no more than 4 slabs will need replacement. As discussed at the site visit it is not possible to anticipate the condition of the slabs to account for this in our bid outside of a pre-determined quantity. Please confirm that our bid should include 4 slabs to be replaced and anything beyond this would be handled via modification?

Per SOW Section 1.3.2.5 Slab Replacement, "it is anticipated that no more than 4 slabs will need replacement." To further clarify, it is assumed that 4 - 25ft by 25ft slabs will need to be replaced.

An alternative option is for materials to recycled at an approved recycling facility that will accept a Waste Manifest and provide a certificate of recycling. If the procedures are followed to ensure clean soil, then it may be recycled once the results are cleared by our Hazardous waste Manager and the facility is approved for recycling. Manifesting is required so that we can track it and a weight ticket provided so we can show diversion from the landfill.

Yes Sec 01 11 00.10

Para 1.3.2.7

As discussed at the site visit, we are looking for clear direction on the disposal requirements related to clean soil from grading operations. JBSA Soil Management Plan promotes the recycling of Clean Soil. Additionally, Section 01 57 20 Paragraph 3.8.1.1 provides a DOD mandate to divert 60% of all non-hazardous solid waste for recycling.

Section 01 11 00.10 Paragraph 1.3.2.7 states, “Waste material shall be hauled off site to approved site following approved waste management plan for hauling of soil to land fill. As discussed, hauling the soil to the landfill is a significant cost to the project. There are many locations that will accept clean fill material for little to no cost, however the landfill will charge a significant cost for each load impacting the final price of the project. This also would be counter to the JBSA Soil Management Plan recommendation of recycling and keeping clean materials out of the landfill. We recommend recycling of clean soil to be permitted. Please advise if this is acceptable?
