Please see the detail titled, “GUARDRAIL POST WITH LIGHT FIXTURE”. A slight revision to the guardrail post size has also been made, increasing from 2-3/8” square to 2-1/2” square, see revised Black Guardrail System detail 7/C7.3.

2. Per the amendment 002. The answer to question #6 gives information for a Trex material. This material cut sheet shows material to be 1"x5.5" that does not meet the 2x6" requirement. Is size that acceptable?

5. Handrails: -C6.2 is the first section view of the handrail/guardrail. These do not match the handrail detail provided on C7.3 detail 7. The only area in which a handrail tube is shown in the drawings is at a location with stairs. With that information, is the guardrail system supposed to match the rail/guardrail/handrail system behind the VC or match the detail and the existing guardrail/handrail combo on the bridge?

· VHB RESPONSE:

· Bridge handrail shall match existing bridge, see revised details provided with Answer to Question #1.

6. Bridge work: -On C4.1 once the top 2" of the bridge is hydro excavated, this drawing shows it to be poured back with exposed aggregate which will not match the existing part of the bridge which is not touched in this contract. Is that what you are intending?

7. Stairs out of the Rotunda and Coffee Shop: -On page C6.6 detail 1 (bottom left of page) the stairs are drawn going the wrong direction. Based on all other drawings you should exit and go down the stairs to the left rather than right back towards the hotel lobby. Which direction is accurate?

· VHB RESPONSE: Correct, exit building and go down to the left as shown on site plan sheet C2.1.

8. Electrical -On E2.1 there is no path to get wiring from the existing panel and lighting controller to fixtures. Is there a designated path for this to occur?

Contractor shall coordinate location of exterior building conduits with family cabin and new generator pad construction.

9. There are many places in the Civil Drawings that details are called out on a sheet S4.2. Per the Index there is no S4.2 Is that sheet missing?
