Questions and Answers dated: 05 Sep 23 Solicitation: FA570323R00040002 Project Title: Camp Sparta Access Roads

Please confirm what demolition works included in this project?

Please see attached map for pad demolition areas highlighted in yellow. In addition, there are 3 abandoned septic tanks that need to be demoed neighboring concrete pads along "West-T connection" segment. Septic tanks are estimated to hold 10,000 gallons. Demolition also includes exisiting culverts and excavation of existing road. If items are located on the pads, then they will need to be relocated by the Contractor. Demolition and relocation of assets will need to be finalized in the creation of the

100% design.

As per site visit, we found three locations of culverts. Do we need to demolish and construct new culverts of three numbers as per drawing. Please confirm?

Demolish and construct new culverts. See question 1.

While executing asphalt works, do we need to make any bypass road or detour? If, yes please provide the details?

Yes. Need to guarantee at least one point of entry/exit to Camp

Canada, Camp Sparta, and Camp Morell at all times during construction.

As per site visit, we wont found any tie distch to exiting flowline. Please confirm, do we need to construct flow line for full pavement?

Please see provided 35% plans.

As per site visit, we found that all over the asphalt pavement location width is not same at all the locations.Please provide the width of the asphlat pavament?

Width of pavement should be 24 feet for all sections.

Are there any under ground utilities at the new pavement construction area. If, yes please provide the details?

There are exisiting ground utilities. Please see attached map for additional information. Map is likely outdated. Air Force is still responsible with updating the map and marking all underground lines along the road. These lines will need to be incorporated into the development of the 100% design.

How many and what type of sign boards required?

Please provide the specifications and images of sign boards required?

Please incorporate signage where appropriate into the development of the 100% design.

At each culvert location do we need install catch basin.

Please confirm?

Please see provided 35% plans.

Please confirm, how many manholes are required to do modification? Please confirm the dimensions of manhole covers to replace?

No manholes are present in this project, but there are existing sewer lines. Please see attached map for estimated locations and manholes and sewer line. Map is likely outdated. Air Force needs to update and map these utilities during development of 100% What are the required technical docuemnts and finanical documenst to submit along with tender? Please see Sections L & M of the Request for Proposal.

Crushed Aggregate base course means 50% Gatch and

50% Aggregate?

Per General Note 10 on G-002, the base course should be 50%

Gatch and 50% Crushed Graded Aggregate (3/4"). Gatch should be a finer limestone material, similar to caliche.

The Culverts mentioned in the plans are existing or should be constructed? Should be constructed. Please see response to answers 1/2.

Demolish of existing barriers are Air force or contracter responsibiltie?

This question needs to be more specific regarding location. If there are moveable concrete barriers, then please notify the Air

Force for their removal. There was an oil tank seen during the site visit, between There was an oil tank seen during the site visit, between the South Tie-in and West Tie-in. Do we need to relocate it? If relocation is not required, please advise the width of the road in that area.

Please see response to question 1. Road width needs to be 24 feet.

As per the site conditions, there are light poles at the center of the road. Do these need to be shifted or

No, but the light poles need to remain functional post construction. Light poles should be positioned at the center of If we are keeping the light poles, do we need to make

All lines are direct burial, not conduit. No manholes are necessary.

If we are keeping the light poles, do we need to make manholes for maintenance of the electrical lines. If so, please provided the specification and number of manholes with location details.

3.7m from edge of pavement feathered to existing earth.

Kindly specify where the pavement is required because it is not clear from the site visit and the drawings.

Incorporate this specification into the development of the 100% design. The road edge of pavement should begin 5 feet from the fence line.

Tie ditches are shown in drawing G-005. However, during the site visit, it was covered fully with sand on both sides. So, if we mechanically clean it, the concrete will be damaged. Are we required to make a new tie ditch on both sides? If so, please advise specifications for the

Please see 35% design to identify tie ditch locations. Please reference specifications and SOW for additional details.

As per SOW 10.1.10, please advise how many existing manholes are there at site.

Please see attached map for manhole locations and estimated feeds. Map is likely outdated. Air Force is responsible with updating the map and marking all underground lines along the road. These lines will need to be incorporated into the development of the 100% design.

As per SOW 10.1.2, Attachment 4 is not provided - the weight of the largest vehicle in the compounds inventory is not provided. See "Design Assumptions" on page G-002 of the 35% design.

As per SOW 10.1.13, please advise how many Stop Signs are required. Do you require any other signages?

Please incorporate signs and locations into the development of the 100% design.As per SOW 11.9 and Drawing G 002, each road

As per SOW 11.9 and Drawing G-002, each road marking needs one line each at the edge and double yellow centerlines. If the light poles are to be kept in the center, please advise how the double yellow centerlines are to be marked. Also, how many lanes are planned for each way?

1 lane for each way. Guarantee 2 way traffic. Centerline marking can be decided during 100% design development. Light poles need to be at the center of the roadway.

As per drawing G-009 and G-0010, are the culvert shown in drawing for electrical lines or storm water? If culverts shown are for storm water, then assuming it to be concrete, please specify the grade of concrete to be used.

Storm water. These details need to be incorporated into the development of the 100% design.

As per SOW 10.1.12, where is the location for PVC culvert and how many meters do we require this culvert?

Do we need to cover the PVC pipe with concrete? Please specify and how many manholes.

q pp p for tracked electrical line locations. Map is likely outdated. Air

Force is responsible with updating the map and marking all underground lines along the road. These lines will need to be incorporated into the development of the 100% design.

Contractor will need to incorporate additional details into the

While construction work starts, do we need to do an alternate path for the vehicle movement at another location or plan a traffic control at the same area?

Yes. Need to guarantee at least one point of entry/exit to Camp

Canada, Camp Sparta, and Camp Morell during construction.

As per SOW 1.2.1, the word “demolition” is mentioned.

Please specify what is expected to be demolished as per the contract. Please see response to question 1.

SOW 11 mentions installation of drainage network for camp

Sparta. As per the drawings only 7 culverts for storm water are shown in the drawing. Is this the only requirement for the drainage network? If not, please Follow attached 35% plans and specifications.

As per drawing G-005, it is shown 5cm for Asphalt surface, 10cm for Asphalt course. However, it is recommended, 7.5cm for both Asphalt surface and course for heavy vehicles. Please advise if this is acceptable.

Pavement lift thickness is dependent on final pavement design. If a smaller aggreagate is specified in surface course, then the pavement thickness should be smaller. If aggregate sizes are the same, then two lifts at 7.5cm will suffice.
