QUESTIONS

1. Question:

Demolition Notes: Note #2. Clearing as described under item P-151 does not require ground disturbance and therefore the project does not require a 1200-C Construction Stormwater General permit. Under Construction Methods specification 162-3.2 Clearing fence line. The specification states that stumps within the cleared area of the fence shall be grubbed or excavated. In the BASE BID Sheet item No. 5.

P-151. Clearing, it shows the quantity as 1.8 Acres. The DEQ requires a permit for disturbed areas of one or more acres. These two specification sections are in conflict. Please clarify.

Sheet C-051. Demolition Notes: Note #2. Clearing as described under item P-151 does not require ground disturbance and therefore the project does not require a 1200-C Construction Stormwater General permit. In the BASE BID Sheet item No. 5. P-151. Clearing, States in the Bid Schedule quantity

1.8 Acres is to be cleared. The DEQ requires a permit for disturbed areas of one or more acres. The disturbed area is over one acre, therefore will the City of Roseburg assume all liabilities and hold the Contractor harmless for not operating under a 1200-C permit.

Clearing shall consist of the removal of all stumps, brush, rocks, trees, or other obstructions that will interfere with proper construction of the fence. Stumps within the clearing area of the fence shall be grubbed or excavated. When shown on the plans or as directed by the RPR, the existing fences which interfere with the new fence location shall be removed by the Contactor as a part of the construction work unless such removal is listed as a separate item in the bid schedule. All holes remaining after post and stump removal shall be refilled with suitable soil, gravel, or other suitable materials and compacted with tampers.

Removal of all stumps, brush, rocks, trees, or other obstructions that interfere with the construction of the fence as described require grubbing and excavation per this section will result in ground disturbing activities.

Holes for the new fence post and electrical bonding bores will require removal greater than 100 cu. yds.

of earth removal. Filling removed fence post, will approximate 50-75cu yds of fill material

The disturbed area is over one acre; therefore, will the City of Roseburg and the DEQ assume all liabilities and hold the Contractor harmless for not operating under a 1200-C permit?

Construction / Preparation for riprap benching will result in ground disturbance. Drilling fence post holes and the removal of existing fence posts and footing require back fill. The scope of work described in the specification and plans will result in ground disturbance activities greater than one acre. Will the City of Roseburg and the DEQ assume all liability and hold the Contractor harmless for not having a 1200-C permit.

An access hole to the ground rod to perform the exothermic welding will result in ground disturbance. Is it the City of Roseburg project approach to construct the project without a 1200-C construction General Permit? Please confirm.

Answer: The area of disturbance for the project will be less than one acre, therefore a 1200-C Construction Stormwater Permit is not expected to be required at this time. Clearing as identified on sheet

C-051 shall consist of cutting and removal of all trees, stumps, brush, logs, hedges, the removal of fences and other loose or projecting material from the designated areas. All stumps to remain, shall be cut flush with the FG. The grubbing of stumps and roots will not be required.

Clearing fence line on sheet C-601 to C-603 shall be incidental to the payment for chain-link fence to installed. Clearing the fence line shall consist of the removal of all stumps, brush, rocks, trees or other obstructions that will interfere with proper construction of the fence. Stumps only within the cleared area of the fence shall be grubbed or excavated. The disturbed area will be less than one acre total.

2. Question: Sheet C-631, Detail 6. Typical fence Post Footing. Fence footing and material notes. Table.

Concrete Footing Depth (A) does not list Line Post Footing Requirements. Please provide line posting details.

Answer: No concrete is required for line post footing. Line post shown in detail 1 on sheet C-631.

3. Question: Sheet C-632. Detail 6. Typical Fence Post Footing. The footing detail shows the concrete post hole fill is to be one-inch higher than the finished grade (FG). To accomplish this requirement a

Sonotube will need to be utilized.

Please provide a typical detail of the fence post perpendicular to the fence line on slopes.

Can the one-inch concrete post fill above the FG be modified to equal the FG?

Answer: Typical fence post detail shown on detail 4 on sheet C-631. Concrete shall be set 1” higher than the finished ground per detail 6 on sheet C-631. Per the FAA General Contract Provisions 80-05, “When the methods and equipment to be used by the Contractor in accomplishing the work are not prescribed in the contract, the Contractor is free to use any methods or equipment that will accomplish the work in conformity with the requirements of the contract, plans, and specifications.”

4. Question Section 162-3.7 requires a 5/8-inch by 8-foot ground rod driven until the top is 6-inches below grade. FAA-STD-019, Lighting surge protection, Grounding. 4.4.4.1 states the ground is to be ¾-inch by

10 feet long and installed 1 foot below frost depth, which at the project location is 18 inches. It appears that the FAA-STD-019 is the more restrictive and therefore the governing document. Please confirm.

Answer: F-162-3.7 states “The Contractor shall comply with FAA-STD-019, Lightning and Surge

Protection, Grounding, Bonding and Shielding Requirements for Facilities and Electronic Equipment, paragraph 4.2.3.8, Lightning Protection for Fences and Gates, where fencing is adjacent to FAA facilities.” Contractor shall comply with FAA-STD-019 paragraph 4.2.3.8 where fencing is adjacent to

FAA facilities, and does not apply. For electrical grounds used on this project, follow the requirements stated in F-162-3.7.

5. Question: Is the installation of ground rods and bonding each strand of security wire and to fence posts required to be performed by a Licensed Electrical Contractor?

Answer: Contractor to follow the requirements of FAA-STD-019.

6. Question: Is an Electrical Permit required?

Answer: We are not aware of any electrical permits required for this work. Unless otherwise explicitly described, it is the contractor’s responsibility to verify and obtain any and all permits required for the work as part of the contract.

7. Question: Is the fabrication welding of gates required to be performed by a certified welder?

Answer: A certified welder is not required.
