STATEMENT OFWORK (SOW)

National Oceanic and Atmospheric Administration (NOAA)

Mauna Loa Atmospheric Baseline Observatory (MLO) Network for the Detection of Atmospheric Composition Change

(NDACC) Roof Repairs Mauna Loa Atmospheric Baseline Observatory, Hawaii

A. PURPOSE:

The NOAA Global Monitoring Laboratory (GML) (MLO requires services to remove the wood decking sitting on the roof of the NDACC building and replace it with pressure treated wood with options to replace the wood with non-corrosive metal with fiber reinforced bar grating for walking surfaces. This will be a full replacement of the system to include design, inspection of the structural membranes of the decking system, new pressure treated wood decking, and better railing system, with options to replace the stair system, replace the wood decking to non-corrosive metal with fiber reinforced bar grating, and complete electrical upgrades.

B. BACKGROUND:

The NOAA Global Monitoring Laboratory (GML) Mauna Loa Atmospheric Baseline Observatory (MLO) is located on the Big Island of Hawaii, at 11,141 ft. above sea level on the north flank of the Mauna Loa volcano. The site is often regarded as the “premier atmospheric science site on earth” and is home to numerous high-profile data sets including the “Keeling Curve” that first documented the rise in carbon dioxide in our global atmosphere. The observatory conducts well over 250 daily climatological measurements, some as precise as 1 part in a trillion.

At 11,141 feet in altitude the sun (UV) conditions can be strong and the air temp significantly cooler than elsewhere on the island which can be detrimental to the buildings, decks and materials located at the site. The current solar deck sitting on the roof of the NDACC building requires a replacement that includes the demolition and replacement of the horizontal wood decking, inspections of the structural membranes and repairs and reinforcement as needed, a new stairs system, a new railing system and electrical upgrades.

Scientific measurements obtained at MLO often represent the global background conditions for the atmospheric research community. As such, the measurements taken at the site are highly precise and need to be safeguarded to ensure that indoor room air and/or local site contamination does note negatively impact the long-term records. 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. The banned construction materials list will be provided to vendors and NOAA can assist with reviewing individual products as needed.

Furthermore, it will be required to keep the science at MLO operational as much as possible throughout construction activities.
