About this file
This document is a Statement of Need for a procurement to furnish a new 30-meter internal-climb sampling tower and optional additional 10-meter section at the Mauna Loa Observatory site in Hawaii. The National Oceanic and Atmospheric Administration's Global Monitoring Laboratory requires a replacement for the existing 40-meter tower, which was built in 1986 and does not meet current structural codes. The base contract specifies furnishing a 30-meter tower with internal platforms at approximately 9 meters, 19 meters, and 29 meters, along with anchors, guy lines, a fall arrest system, and vertical cable management from top to base to accommodate tubing and cabling. There is also an option to procure an additional 10-meter section with a platform at 39 meters and associated fall arrest system and cable management. All materials must be approved against NOAA's banned chemicals list and delivered to the Mauna Loa Observatory site, located at over 11,200 feet in altitude at the end of an approximately 90-minute one-way access road.

Mauna Loa Observatory Tower Procurement

1305M322QNRMJ0052
Summary:
The NOAA Global Monitoring Laboratory (GML) Mauna Loa Atmospheric Baseline Observatory (MLO) is in need of a new 30 meter tower and optional 10 meter tower for atmospheric sampling.
The current tower, located at MLO, was built in 1986 and stands 40m tall. It is an internal-climb, staircase-scaffolding, sampling tower and has platforms located at every 2m. Additionally, four of the platforms are outfitted with quad receptacle power outlets. There is no known structural damage to the tower itself, however the guy line anchor points are rusted, and the tower is already 36-years old and does not meet current code requirements.
The MLO facility is located at the end of an 18-mile one-lane access road reachable from Saddle Road. The start of the Mauna Loa Access Road is located just to the east of the more well-known access to the Mauna Kea Visitor Center and telescopes. Logistically, the site is at over 11,200 feet in altitude and the sun (UV) conditions can be strong and the air temp significantly cooler than elsewhere on the island. The 18-mile driveway can be challenging for longer vehicles due to the narrow width, rolling topography, and occasional sharp corners. The power lines do cross over the road in multiple locations along the upper half of the MLO access road and may pose an overhead obstruction issue for very tall vehicles (no known issues with the power lines obstructing access to the site historically). The one-way commute time to the MLO site from either Hilo or Kona typically takes ~90-min.
NOAA has developed a comprehensive banned construction materials (chemicals) list and each product used at the site must be cleared against this banned chemical list prior to use (attachment -3).
***All material shall be new; no refurbished materials will be accepted.***
