c. Overburden removal and grading.

d. Rock and gravel for pad, reinforced concrete catch basins, drains and erosion control.

5. Construction will include but is not limited to:

a. Installation of new steel cattle guards with reinforced concrete catch basins functionally similar to the existing cattle guards and rated to American Association of State Highway and Transportation Officials (AASHTO) U80 standard.

b. Concrete approach aprons min 24” to each side of new cattle guard.

c. New asphalt patching as required.

d. Installation of new weather resistant composite fencing on each side of the road attached to the cattle guards.

e. Installation of 8” UV protected HDPE double wall drain pipe to extend 10’ to 24’ beyond the basin, and erosion control and end sections at the drain water outlet to protect the environment. The following items are a summary of the project and are provided solely for the purpose of describing the general nature and constraints of the work.

5. Construction Hours. Work shall take place during normal business hours, 0700 to 1600, Monday through Friday, weekends and national holidays excluded.

6. Road Access and Closures:

a. Mt. Ka’ala road uses controlled access via three locked gates. Road traffic is coordinated using handheld radios to avoid conflict between up and down traffic. In addition to milage markers, sequential culvert numbering (1-80) provides road position.

b. With prior coordination, the Ka’ala road can be closed to all traffic during periods between 10:00am and 4:00pm, Monday through Friday. Such as when existing cattle guards are removed and replaced. Closures are normally limited to 4 hrs.

in length but can be extended up to 6 hours on a case by case basis.

c. Outside of road closure periods, work can continue allowing for unfettered road use by operational vehicle traffic. Radio coordination of traffic headed up/down provides time to ready work site(s) to allow traffic through.

d. Outside of the road closure periods, and project work hours, unattended road access is required to maintain unfettered traffic flow 24/7 (e.g steel plating, temporary bridge, temporary rerouting around work site).

7. Construction material shall be stored only in FAA approved areas.

8. Construction staging shall be allowed only in the FAA approved areas.

9. The Contractor shall provide all temporary services required for construction.

a. The steel cattle guards will sit flush within the concrete water catch basins and need to withstand a AASHTO U80 standard vehicle load. The cattle guard needs to be designed for convenient removal for maintenance using existing road maintenance equipment (e.g Caterpillar 236D3). The fencing on each side of the cattle guards needs to be designed for convenient removal and detachment from the cattle guard base for wide load traffic.

b. The concrete catch basin and cattle guard construction is a major component of this project, and prior to purchasing or completing involved design work, submittals must be reviewed and approved by the FAA representative for this project.

c. Concrete catch basin drains shall be a minimum of 8”in diameter. 4 of the 5 catch basin drains need the drain flange located in lower left corner of the basin

d. and 1 of the 5 catch basin drains need the drain flange located in the upper left corner. Drain locations will be confirmed on the contractor site walkthrough.

e. Drain piping: Extend 8” UV/weather resistant HDPE pipes out of basin 10’ to 24’ as required for each cattle guard using manufactured fittings. Install pit run rock and pipe ends at the end of the drain to prevent soil erosion and bury remaining piping with appropriate material.

2. The new cattle guard assemblies and its subparts must be reviewed/stamped by a licensed PE registered in the state of Hawaii.

3. Prior to final design approval, review is required at 50% completion and another at 90% completion to address any comments/questions or changes to the project with FAA representatives. Submittal will be reviewed for proper operation and compliance with requirements detailed in this section.

4. Submittals

The COR will review the contract documents and verify that the Contractor has completed all required work. If work remains to be completed, an itemized list will be prepared, and the contractor at no additional cost to the Government shall complete the remaining tasks correctly. A Joint Acceptance Inspection (JAI) requires FAA personnel to be present and it may be held concurrently with the CAI.

D. Demolition

1. Remove and properly dispose of all clean non-contaminated construction debris, overburden (vegetation, soil, rocks, etc.,) off site. Cut existing asphalt back if needed so damage does not occur to existing asphalt. Any contaminated overburden (asphalt, metal, concrete, etc.,) must be disposed of in accordance with state and local regulations and removed from site. The FAA will retain copies of disposal if required.

2. Privately owned fencing abutting existing cattle guards will be disassembled and removed for reuse and restoration of fence line to new cattle guards. At a minimum, the fence line work will extend to the first fence post away from each side of existing cattle guards.
