Samoa Atmospheric Baseline Observatory Driveway Repairs Samoa Atmospheric Baseline Observatory, Tutuila Island, American Samoa

A. PURPOSE:

The American Samoa Atmospheric Baseline Observatory (SMO) requests services to repair the

0.5 mile paved asphalt road that connects the main road (Route 1 in the village of Tula) with the observatory. Work shall include, reinforcing the edges of the road using wood nibs and concrete, installing concrete swales at portions of the road, widening two turns, hot melt and seal a portion of the road and installing a new drainage system at the base of the mountain.

B. BACKGROUND:

The National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Laboratory (GML) operates a year-round long-term atmospheric research facility on Cape Matatula, American Samoa. The American Samoa Atmospheric Baseline Observatory (SMO) is one of NOAA’s four atmospheric baseline observatories worldwide and monitors the composition of air flowing off the Pacific Ocean. Sitting on a 26.7-acre parcel of land, the observatory hosts a number of complementary atmospheric research projects from universities, federal agencies, and foreign research groups.

Logistically, a 0.5 mile paved asphalt private road connects the main road (Route 1 in the village of Tula) with the observatory facility. Following the contours of the hillside, it is a narrow road with many twists and steep hills. The driveway can be challenging for longer vehicles due to the narrow width, rolling topography, and occasional sharp corners. All Wheel Drive and Four Wheel Drive vehicles are recommended for accessing the observatory, especially when the roads are wet from rain storms. Trees and dense vegetation may also pose an overhead obstruction for the tallest vehicles and/or vehicles that are extra wide.

American Samoa is a highly corrosive environment. The island receives frequent, heavy rainfall (approx. 200 inches of rain annually) and averages around 80 degrees F (26.7 C). The high humidity and salt spray from the ocean expedite corrosion, making repairs to the narrow road imperative for the safety of the staff and visitors of the observatory. This solicitation is a follow-on project to two road repairs made in 2020 and 2024. The road repair in 2020 was specifically designed to simply repave the upper 1700 ft of road and did not include edging or drainage systems. The road repair in 2024 was to simply re-pave the bottom half of the road (about 1700 ft) and install wood nibbing for edge reinforcement. Due to the highly corrosive environment we request additional services in this solicitation to reinforce the edging of the road and widen certain areas in order to create a safer driving environment for staff and public outreach visitors.
