Contractor Questions and Answers

1. Will the standard 90 min time limit for concrete to be poured be upheld on this one? By the time concrete is loaded up at the nearest plant, drives to the nearest location to load up a barge, and is pushed to the jobsite 20 miles away the concrete will be at or nearing the time limit. We can ensure the curing process is slowed down with retarder so that concrete is still pourable once it gets on site, but if the time limit is upheld this will not matter.

Time limits for delivery and placement of fresh concrete depend upon approved mix design submittals.

2. Question 17 was answered “See Amendment 0001,” but Amendment 0001 added only Section 31 11 00.00 12 (Clearing and Grubbing) and the revised drawings; we are unable to locate a silt-fence detail, plan location, or required extents. Please confirm whether perimeter silt fencing or other erosion/sediment-control BMPs are required, identify the locations and extents on the drawings, and confirm the pay item under which erosion control is to be priced, since the revised Pricing Schedule contains no separate line item for it.

Silt fence limits are shown on Drawing C-103, Rev. 1. Refer to Amendment 0001 for further clarifications.

3. The Government confirmed a SWPPP is required per Section 01 57 23.00 12.

The revised Pricing Schedule has no separate line item for SWPPP preparation, implementation, inspections, or BMP maintenance. Please confirm under which lump-sum item this work is to be carried (e.g., 0001 Mobilization and Demobilization).

Refer to paragraph1.3.1 of Section 01 57 23.00 12.

4. Question 12 (topsoil stripping depth) was deferred to the new Clearing and Grubbing section. New Section 31 11 00.00 12 covers clearing, grubbing, and vegetation removal to within 6 inches of the ground surface below the building, ramp, and stair foundations, but does not state a topsoil stripping requirement or depth. Please confirm whether topsoil stripping is required, to what depth, and that it is included in the “Clearing and Grubbing” pay item (0016).

Refer to revised 31 11 00.00 12 with Amendment 0003.

5. Sheet S-101 (Overall Pile Layout and Platform Framing) was deleted and replaced by Amendment 0001. Please confirm that the revised pile layout reconciles with the estimated quantity of 4,235 LF for item 0010 (Precast Prestressed Concrete Piles), and clarify whether the test pile and the support piles required for the load test — which Section 31 62 14.00 12, para. 3.3 required to be pulled — are included within the 4,235 LF or are paid separately in item 0011.

The pile layout was not revised. The estimated quantity of 4,235 LF for item 0010 Precast Prestressed Concrete Piles remains unchanged. The pile(s) involved with the load test are to be paid separately in item 0011 (Refer to Amendment 0001).

6. Amendment 0001 confirms the building is “Partially Open” with internal pressure coefficient ±0.18, basic wind speed (Vult) 164 mph, and Vasd 127 mph, and that the roof slope remains 3:12 with hidden-fastener roof panels. Please confirm these values supersede any “partially enclosed” references elsewhere in the plans and specifications and confirm the single set of wind/enclosure criteria the PEMB manufacturer is to design to so that bids are on a common basis.

The criteria listed supersede any “partially enclosed” references elsewhere in the plans and specifications and represent the single set of wind/enclosure criteria the PEMB manufacturer(s) are to use in their design(s).

7. Question 22 (an area where a ramp barge could land so cranes, lifts, and equipment can be driven off) was answered “See Amendment 0001.” We are unable to locate the referenced photographs/exhibit in our copy of Amendment 0001.

Refer to sheet grid N-11 on Drawing C-103, Rev. 1.

8. Amendment 0001 substitutes Sheets C-103, S-001, S-101, S-201, and S-301.

Please confirm whether these revisions change any dimensions, quantities, or details on companion sheets that were NOT reissued (e.g., C-104 transition paving relative to revised C-103, and S-403 precast details relative to revised S- 301), and confirm those companion sheets remain in effect as originally issued.

Updated information is indicated by the revision clouds and delta marks.

All other information remains unchanged from the original issuance.

9. Given the 5-ton bridge limit precludes concrete trucks and large trucks reaching the site, and the rack location is to be coordinated with the Lockmaster, please confirm the Truck Wash-Down Rack (item 0002) is still required and clarify the intended use/sequencing so it is priced consistently across bidders.

Section 01 57 23.01 12 TRUCK WASH-DOWN RACKS still applies. As stated in paragraph 3.1 of this Section, the intended use is to eliminate mud and debris transported onto public roads.

10. With less than one acre of disturbance, please confirm whether a Notice of Intent (NOI) filing with LDEQ under the construction general permit is required in addition to the project SWPPP, or whether the SWPPP alone satisfies the requirement.

In Section 01 57 23.00 12, refer to paragraph G.2 in PART II of the LPDES

GENERAL PERMIT FOR STORM WATER DISCHARGES FROM SMALL

CONSTRUCTION ACTIVITIES.

11. Referencing Amendment 1 - Q&A #: 4 “Could the duct bank be of a precast concrete duct bank if contractor elects? Precast concrete duct bank option is acceptable.” - Since the Duct bank can be a precast duct bank, does the manufacturer of the precast duct bank also have to be a PCI certified in Category C1 work per the specifications for the precast columns, beams, slabs, etc.?

PCI certification is required under Section 03 45 33 PRECAST STRUCTURAL CONCRETE for precast concrete framing. A precast duct bank for electrical conduit does not constitute a load resisting structural element and would not be subject to the provisions of Section 03 45 33.

12. Referencing Amendment 1 - Q&A# 27 “Please provide the bases of designs for the pre-engineered metal building and the insulated panels. Design criteria are identified in the plans and specifications.” - Specification section 13 34 19, paragraph 2.3.3 Secondary Framing states, “Fabricate framing from cold-formed, structural-steel sheet or roll-formed, metallic-coated steel sheet pre-painted with coil coating, unless otherwise indicated, but plan sheet S-001 states ALL

FRAMES, GIRTS, PURLINS, BASE PLATES, ETC. SHALL BE HOT-DIPPED

GALVANIZED. Is plan page S-001 considered to be “unless otherwise indicated”, or can all secondary members be light gauge material cold-formed / pre-galvanized?

As many light gauge members are too thin for the hot-dip galvanizing process, secondary members can be cold-formed from zinc-coated (pre-galvanized) sheet steel and are not required to be hot-dip galvanized after fabrication.

13. Referencing Amendment 1 Q&A # 27 “Please provide the bases of designs for the pre-engineered metal building and the insulated panels. Design criteria are identified in the plans and specifications.” - We do not believe all design criteria has been identified in plans and specifications. Can you please confirm gauge size for roof and wall panels and for secondary framing?

Design criteria have been provided for vendors to determine loads on the building and precast support elements. Material sizes and thicknesses to successfully and competently resist the design loads and deliver such loads to the foundation are to be determined by structural system vendors.

3.2 INSTALLATION OF SILT FENCE BARRIER

The silt fence shall be located as indicated on the contract drawings.

Geotextile shall be from a continuous roll cut to the length of the barrier to avoid the use of joints. When joints are unavoidable, geotextile shall be spliced together at a support post, with a minimum 6-inch overlap, and securely sealed. A trench shall be excavated approximately 4 inches wide and 6 inches deep on the upslope side of the location of the silt fence. The 4-inch by 6-inch trench shall be backfilled and the soil compacted over the geotextile. The geotextile shall be attached to the land side of the post with wire or other method recommended by the manufacturer and such that a 6-inch length of geotextile is left unattached at the bottom of the post, the unattached geotextile embedded in the trench and the trench backfilled. It is the responsibility of the Contractor to maintain the integrity of the silt fence. The Contractor shall immediately correct any deficiencies. The silt fence shall be promptly repaired or replaced should it become damaged or otherwise ineffective. The silt fence is to remain in place upon

SECTION 01 57 23.00 12 Page 6 ED 22-050 completion of the project, or as directed by the Contracting Officer. Its maintenance shall be continual for that period of time for which excavated materials are placed in the area of the silt fence.

3.3 MAINTENANCE

The Contractor shall maintain the temporary and permanent vegetation, erosion and sediment control measures, and other protective measures in good and effective operating condition by performing routine inspections to determine condition and effectiveness, by restoration of destroyed vegetative cover, and by repair of erosion and sediment control measures and other protective measures. The following procedures shall be followed to maintain the protective measures.

3.3.1 Silt Fence Barrier Maintenance

Silt fences shall be inspected in accordance with paragraph INSPECTIONS.

Any required repairs shall be made promptly. Close attention shall be paid to the repair of damaged silt fence resulting from end runs and undercutting. Should the geotextile on a silt fence decompose or become ineffective, and the barrier is still necessary, the geotextile shall be replaced promptly. Sediment deposits shall be removed when deposits reach one-third of the height of the barrier. Sediments shall be utilized in the job or disposed of as construction debris. When a silt fence is no longer required, it shall be removed. The immediate area occupied by the fence and any sediment deposits shall be shaped to an acceptable grade.

3.4 INSPECTIONS

3.4.1 General

The Contractor shall inspect disturbed areas of the construction site, areas used for storage of materials that are exposed to precipitation that have not been finally stabilized, stabilization practices, structural practices, other controls, and area where vehicles exit the site at least once every fourteen (14) calendar days, before anticipated storm events (or series of storm events such as intermittent showers over one or more days) expected to cause a significant amount of runoff, and within 24 hours of the end of any storm that produces 0.5 inches or more rainfall at the site. Where sites have been finally stabilized, such inspection shall be conducted at least once every two weeks.

3.4.2 Inspections Details

Disturbed areas and areas used for material storage that are exposed to precipitation shall be inspected for evidence of, or the potential for, pollutants entering the drainage system. Erosion and sediment control measures identified in the SWPPP shall be observed to ensure that they are operating correctly. Discharge locations or points shall be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to receiving waters. Locations where vehicles exit the site shall be inspected for evidence of offsite sediment tracking.
