QUESTIONS AND ANSWERS

Solicitation #: W912C3-18-R-0006 Water Piping Replacement Phase

III

QUESTIONS AND ANSWERS:

1. Drawing Sheets 3, 4, 5, 6 do not show existing water piping lines, only valves, hydrants, and other items. Also, some components to not match with the master layout on sheet 2. Can drawings that show the water lines be provided?

Answer: Drawing of Existing Drawing Distribution was provided for references on Amendment 001 posted on FBO.gov on 10 Aug 2018. The information was obtained from a professional surveyor and military units.

2. Are other plans with existing utilities (other than water) available for review?

Answer: PDF versions drawings of existing utilities was provided on Amendment 001 posted on FBO.gov on 10 Aug 2018. The information was obtained from a professional surveyor and military units.

a. Cable TV

b. Street Lighting

c. Storm Sewer System

d. Electrical Distribution

e. Telephone System

f. Sanitary Sewer System

3. Drawing sheet 2 shows 2 existing water connections for what seems to be a parking lot with solar panels (Columbus Street). The new intended water distribution system on page 7 does not show any water connections to that area. Are water connections required for that area?

Answer: Yes, all existing facilities shall have water connections.

4. Drawing Sheet 7 of 10 does not indicate the size of the PRNG Building Connection.

Is the size of the connection available?

Answer: The size of the PRNG connection is not available. For concepts of the proposal estimate the contractor may consider an 8” connection.

5. Note 24 from drawing 9 of 10, establishes that: “Existing submersible pump, pipes and their accessories shall be removed while contractor install the new water pipes.

Contractor shall design and build new catch basin to collect water from surroundings.

Contractor shall install new submersible pump, electrical system, pipes and their accessories for a proper function.”

a. Please provide current pump specifications, past performance, and force line details. Also, please confirm that pump will be used to manage storm runoff.

Answer: Contractor shall consider to provide new submersible pump with same technical characteristics as the existing or similar. Contractor shall take into consideration the following:

1. Submersible pump of 3 inches diameters for discharge

2. Voltage: 230

3. Frequency: 60 Hz

4. Phase: Single

5. HP: A minimum of 3

The purpose of the pump is to mitigate the flooding issues in that particular area.

6. Section 1.8 Salvage Materials and Equipment requires the DB Contractor to provide a salvage plan, listing material and equipment to be salvaged, and their storage location.

It also establishes that: “The following Salvage Material has been identified by the government when pipe disconnections from existing lines are performed:

i. Mechanical Joint Elbows (long and short radius)

ii. Mechanical Joint Tee

iii. Mechanical Joint Curves (11.25 and 22.5 degrees)

iv. Mechanical Joint Coupled Joint Pip”

b. If the intent is to abandon existing lines, please clarify is this provision applies only to incidental encounters and/or possible connections. Please clarify the intent of this task or how is expected to be achieved.

Answer: This condition apply to either incidental encounters (pipes broken due to trench work) or point connections on Phase I and II but not limited to additional impacted areas. Contractor is responsible to establish a plan to achieve this task, however, the government will provide the approval/disapproval actions regarding the plan.

7. Please confirm that the valves shown on the distribution piping drawings are not the same as the isolation valves called on drawings General Notes #16 t at requires isolation valves within 10 Ft of the buildings.

Answer: Correct. All buildings/facilities shall have an isolation valve at a minimum distance of 10 feet away from the facility. The other valves corresponds to the main water distribution grid, fire hydrants, and fire suppression connections, among others.

8. On Solicitation page 52, Item 1.2.3.1.D it indicates that the government may provide non-potable water as needed. Will non-potable water be provided (from a source within the facility) for testing water piping and will the source of the water require that the water be loaded and transported by means of a water truck?

Answer: For pressure tests and housekeeping purposes, government will provide a non-potable located next to BLDG 161 (Water Spout). Contractor shall transport the non-potable water into a Water Truck Tank to the points where pressure tests will be conducted.

d. Is there a minimum requirement for bedding coverage around the pipes?

Answer:

a. Designed of Record and contractors shall consider 2 inches of top soil.

Contractor shall consider the following sodding type: Zoysia

b. The sand bedding is acceptable.

c. The minimum requirement for trenches depths is 3.6 feet from bottom to ground surface. This will apply to pipes with diameters from 4 to 10 inches. However, the minimum requirement for trench depth regarding two inches is 2 feet.

d. The minimum requirement is 5 inches around the pipes.

10. On solicitation page 71, Item 3.3.E indicates that contractor shall leave abandoned in place existing piping that may contain asbestos and perform asbestos abatement only if incidental disturbance occurs and/or for water piping connections.

d. Due to lack of companies available and dedicate to recycling asphalt and concrete materials along the island, contractor shall considers to dispose those materials at municipal landfills.

e. This is a federal installation, so Puerto Rico Department of Transportation has no jurisdiction in here. No AADT is needed within Fort Buchanan boundaries.

14. On solicitation page 72, Item 3.4.2.b indicates that contractor shall provide pressure reducing valve stations. Without a design, this costly item would be difficult to estimate with accuracy.

Not having current status of the operational state of the systems makes this requirement difficult to assess.

a. If test are performed and they do not pass, what would be the contractor’s responsibility?

b. Please provide more specific requirements, or if the government will verify system operational status before and after the connections are performed.

a. Contractor is responsible to make the fire suppression connections. Contractor shall validate there is water running thru each system.
