Solicitation No: 1240LT22R0005 GAOA-Silver Lake Boardwalk-Uinta-Wasatch-Cache National Forest, Utah

Solicitation Questions Page 1 of 2

Q: May alternative materials be submitted (prefabricated galvanized steel frames or similar)?

(Question was paraphrased)

A: At this time the proposal shall be based on the drawings and specifications. Alternative materials may be mentioned in the technical proposal and a second price may be proposed. After the award, value engineering may be approved. However, there is no guarantee that these methods will be accepted and if that is the case, the installation will need to proceed per the drawings and specifications.

Q: Do you have any way of finding out if there is currently snow coverage at the boardwalk? I’ve tried calling multiple places local to no avail. I’m planning to visit the site around May 1.

A: There is still snow at the site. Snow at this elevation can remain until June.

Q: Is the water level going to be lowered to soil levels for ease of construction at the new Fishing Dock locations?

A: No.

Q: Can you release the site visit sign in sheet from November 2021?

A: The site visit sign in sheet will not be released.

Q: Period of performance is listed at 120 days plus 15 days per option. Is this timeframe flexible? the project is quite large to complete in four months.

A: This is the allotted time to complete the work. If additional time is needed to procure materials it may be negotiated. Also, if the work is stopped by winter, a stop-work can be issued to delay work until the next season.

Q: Would Southern yellow pine be an acceptable alternate wood species?

A: After award, value engineering requests may be approved if they benefit the government.

Q: Glu lam design spec needed. Normally a glulam design code is given which indicates the member types, etc. Would treated paralam beams be an acceptable alternative?

A: See SECTION 061800 - GLUED-LAMINATED CONSTRUCTION in the specifications. The member sizes are shown on the plans. After award, value engineering requests may be approved if they benefit the government.

Q: We do not see a design page for deck #6. is it the same as deck 3?

A: The layout of Deck #6 is on sheet D3. Structural design is per detail B/S104.

Q: Plan pages C2-C6 have notes denoting handrail begin and stop. We assume these are the only areas with handrails. Does the balance of the boardwalk have a curb or just open side deck? We would request a cross section of boardwalk without handrail.

Solicitation Questions Page 2 of 2

A: Handrails are only to be built in the areas shown in the details on SP3-SP8 and D1 through D4. The boardwalk has edge protection in all areas per the detail on sheet D5. The framing members below the decking are shown on detail 1/A1.01.

Q: Wood treatment plan notes call for Copper Napthenate or Penta in heavy oil for structural and Penta in light oil for handrails. Specs call for waterborne treatment without arsenic. Please advise which is to be used.

A: Since Penta is no longer available, the handrails may treated with arsenic-free waterborne treatment that meets category UC4a such Clearguard 25 or other equal. Please price all other decking, curbing, joists, and beams with copper napthenate in heavy oil meeting category UC4b.

Q: We would like to know the following loading info that will be applied to the piers:

1. Axial loads Compression and Tension

2. Lateral loading or shear

3. Any moments applied to the piers.

A: The axial loads have been specified on the structural plans (sheets S001 through S202). Many of the piers will be installed with a batter to resist lateral loads. Specific vertical load, moments, and lateral load values have not been specified by the structural engineer.
