15 Amendment 0004, Q&A #5, Section L

Amendment 0004, Q&A response number 5, references personnel positions and key trades, which are not currently included in Section L. We concur that this information was previously included in Solicitation No. 140P2024R0150;

however, the Section L provided with the new solicitation (140P2025R0080) does not include the same level of detail for Subfactor 1B – Key Personnel Experience or most of the other Factors/Subfactors (e.g., Subfactors 1A, 2A, 3A, 3B and Factor 4). It appears that Section L has been replaced with the exact same language as Section M. Please advise if we should follow the new Section L or if the detailed requirements will be added.

25 Tank Demo Drawings

Do the existing water tanks have sand and gravel beneath them? If so, please provide details. Historical drawings for the tanks indicates a sand custion underneath. No dimensions were found for the 50K gallon tank. For the 100K gallon tank, the original as builit drawing shows the sand cushion under a slope at the tank bottom where it is 4" thick at the walls and 9" thick at the tank center. This information was not independently verified during design of this project.

26 C704, C705, C706, C713, C714, C715

Please provide the scale for drawings C704–C706 and C713–C715. This information is not available at this time. You may use the available dimensions on the drawings for estimation purposes.

27 C711 Drawing C711 does not provide an elevation based on the topography for the new 100,000-gallon tank. Instead, it uses an arbitrary elevation of 100.00 for the tank floor. Please provide the actual elevation relative to the topography shown on C711.

This information is missing from the plans. However, the approximate elevation found on the site plan and the dimensions in the drawing details are believed to be sufficient for bidding purposes. Survey and control point information can be set after contract award. 5

28 C701 & C702 Drawing C701 notes an existing 4" AC pipe to be protected in place, while drawing C702 indicates it should be removed. Is this line to be removed, or is it mislabeled? C702 shows two existing lines descending the slope, whereas C701 shows three. Please clarify.

Sheet C701 is correct that the 4" AC pipe may be protected in place except as noted in sheet G103 note 5. Sheet C701 shows the new 6" campground distribution line, while sheet C702 shows existing lines only. 5

29 C702 Drawing C702 does not provide an elevation based on the topography for the new 50,000-gallon tank. Instead, it uses an arbitrary elevation of 100.00 for the tank floor. Please provide the actual elevation relative to the topography shown on C702.

This information is missing from the plans. However, the approximate elevation found on the site plan and the dimensions in the drawing details are believed to be sufficient for bidding purposes. Survey and control point information can be set after contract award. 5

Means and methods are up to the contractor provided they do do not conflict with plans or specifications. 5

46 C507 Section 1 After welding the knee brace to the galvanized pipe, can spray galvanizing be used to touch up the welded area? Means and methods are up to the contractor provided they do do not conflict with plans or specifications. 5 47 C507 Section 1 Please provide specifications for the required signs, including size, lettering dimensions, and color. Should have 10 14 00 within specs? 5 48 C508 Are the bollards required to be painted? Per C507, yes. "Traffic yellow" 5

50 C412 & C413 Several notes reference the "edge of pavement," but there is no indication that the roads are asphalt. Drawings C408 and C409 show pavement in part of the campground. Please provide a drawing showing all asphalt pavement areas.

Reference Legend on G103, See sheets C206-C304 & C404-C411

51 C410 & C411 These drawings are labeled "South Water." Are they part of CLIN 3, Twin Peaks Campground? See Sheet C403 which shows interface for CLIN 3 and CLIN 4. 5

52 C412 & C413 A note states to remove the existing pipe when exposed in the new trench. What type and size is the existing pipe? The original campground water system had a 4" line down the center of the campground, branching to 2" lines to comfort stations and

3/4" lines to hydrants. The location of existing lines was located and shown on the plans, but the size of all lines was not independently verified during design of this project.

53 C412 & C413 The term "shut-off valve" is used, but no detail is provided. Do you mean a buried Corp Stop or a Corp Stop with valve box?

This refers to a valve installed at each lateral to allow branch to be shut off by operators if needed. 5

54 C505 Can internal restrained couplings (e.g., Eagle Loc900, Certa Lok, Diamond Lok21) be used instead of the external retaining system?

For the purpose of the bid, follow the plans and specifications. During performance of the contract, use of comparable products can be requested in accordance with 01 67 00. 5

55 C412 & C413 Are all service lines in the campground (excluding the Comfort Station) the same length from the main line? See sheet C414 which provides lengths of pipe sections and coordinates for branches in the campground. 5

57 C413 The third row from the top shows a 2" x 1" service line pointing to two comfort stations, but does not mention the station lines. Are there two lines at each comfort station? Please ensure consistency across drawings.

There is one service line for each comfort station. 5

58 C410 At stations 41+07 and 42+47, new services with spigots are indicated, but the same locations also show removal and replacement of spigots. Please clarify.

Removal of service and spigot and replacement of service and spigots is the intention. 5

60 South Water System You state there are currently two parallel waterlines, one of which is to be removed and replaced with a new 6" C900 pipe. What is the size and type of the pipe being removed, and what is the distance between the two existing pipes?

Per sheets C404-C407, existing distribution line is 4" C900.

61 C407, Note 5 To properly bid this scenario, an additional line item should be added to the Contract Price Schedule Template to address the cost if CLIN 3 is not funded. 5

62 General What type of pipe is used for the existing services? Typically the existing water service lines are 1-inch PVC. 5

63 C701 & C702 Drawing C702 notes removal of the 3" Campground Distribution Line, while drawing C701 states to protect it in place. Please clarify.

Removal of this section of AC pipe is not required except as noted in sheet G103 note 5. 5

64 C704, Item 17 Item 17 should specify a 6" gate valve, not a 4" gate valve. Sheet C704 item 17 should refer to a 6" gate valve due to the size of the pipe. 5

65 C406 At station 14+97.73, a blow-off is referenced, directing to Drawing C504, Detail 2. However, Detail 2 appears to show a fire hydrant, not a blow-off. Please confirm whether a separate blow-off detail is available or provide the appropriate detail for the blow-off installation.

A transformer will have to be mounted on an APS power pole, or a pad mount transformer and electrical pedestal could be installed at the base of an APS power pole. Then a trench will have to be dug from that point, then wire install inside conduit run to the 100K tank.
