Regarding Schedule Item #4 Crushed Rock Installed – on page 61-6, paragraph C. Crushed Rock, Installed of the specification package it states > “No Crushed rock shall be delivered to the site until the Contracting Officers Representative verifies that foundation conditions warrant the use of such material.” This is an optional Item for this project, the COR will decide if it is needed at the pre-construction meeting.

Questions:

Q1: Is there going to be a need for a Port-a-Potty (chemical toilet)?

A1 : Yes, According to Page 8-2 of the specification mobilization. “This item shall also include providing a chemical toilet (port-a-potty) on each job site.”

Q2. The Specifications state that the riprap thickness will be 48” in section 8 a, however the drawing shows 24” thickness. What thickness will be desired, as this will affect the gradation according to the table included in section 8 a of the specifications?

A2. There is an error in the construction specification items of work for Rock Riprap installed. On page 61-4 under paragraph a. line (1). The thickness of 48” for riprap should read thickness of 24” (which matches page 2 on the construction drawings.)

Q3. From the drawings it appears the stabilization ends slightly before the existing electrical pole in jeopardy at the site seen in the attached picture. Is the contractor to slope the western bank of the channel to a 2:1 up to the electrical pole?

A3: This electric pole, in the photo, is not in jeopardy of being in the slope of the shaping limits. The channel liner will go from Station 0+00 to Station 2+60 the electric pole in the picture is approximately 20 ft. beyond station 2+60.

Q4. Is it anticipated that import fill will be needed prior to the riprap bedding placement or will the onsite earthen be used to shape the channel as desired?

A4: There is no anticipation of imported fill material needed on this project. The earth material from the shaping of the 2:1 slope on the west bank will be used as fill material, if needed.

Q5. What size rip rap will be desired 12”, 18”, or 24” and what overall thickness (depth).

A5. A1: The size of the riprap for Bid Item #2 is dictated by the thickness (24”) on the gradation table on Page 61-5 in the specification (Top of the page).

The gradation reads as below.

Max size is = 24” Avg. Weight = 225-400 lbs.

Avg size = 15-18 inch None smaller than = 9 in.

Any gradation that a rock quarry provides will need to meet the criteria from the table on page 61-5. It is the understanding of the technical representative that most rock quarry’s call this 12-inch riprap.

Q6: Is this project tax exempt?

A6: The government shall not be charged sales tax on invoices, and the government’s tax-exempt status is not directly conveyed to the contractor for their purchase of supplies or materials. The following is an excerpt out of FAR Part 29.303 Application of State and local taxes to Government contractors and subcontractors.

(a) Prime contractors and subcontractors shall not normally be designated as agents of the Government for the purpose of claiming immunity from State or local sales or use taxes. Before any activity contends that a contractor is an agent of the Government, the matter shall be referred to the agency head for review. The referral shall include all pertinent data on which the contention is based, together with a thorough analysis of all relevant legal precedents.

(b) When purchases are not made by the Government itself, but by a prime contractor or by a subcontractor under a prime contract, the right to an exemption of the transaction from a sales or use tax may not rest on the Government’s immunity from direct taxation by States and localities. It may rest instead on provisions of the particular State or local law involved, or, in some cases, the transaction may not in fact be expressly exempt from the tax. “
