Statement of Work (SOW) Building 1 Raise at the Lake Michigan Field Station

National Oceanic Atmospheric Administration (NOAA)

Office of Atmospheric Research (OAR) Great Lakes Environmental Research Laboratory (GLERL)

Lake Michigan Field Station (LMFS) Muskegon, MI

PURPOSE:

Raise Building 1 in order to prevent groundwater infiltration at the government owned Great Lakes Environmental Research Laboratory, Lake Michigan Field Station, located in Muskegon, MI.

The Contractor shall furnish all personnel, materials, equipment, travel, services and facilities as necessary to perform specific tasks described herein. Engineering personnel shall be licensed and appropriate for this type of project.

HISTORY:

Historic Building 1 is the original, historic, caretaker’s building for the site lighthouse. Building 1 houses the site administrative offices, a meeting area, and laboratory work space in the basement and contains dormitory beds on the second floor. The laboratory work space in the basement is currently sidelined due to water/flooding risk.

BACKGROUND:

Historic Building 1, built in 1905, is located adjacent to Lake Michigan and the Muskegon Channel.

Lake Michigan is having record high lake levels and cracks in the basement floor are allowing significant volumes of water to enter the building on a regular basis regardless of storm or rain events.

There are presently four sump pumps located in the basement level to pump the water out of the basement into the sewer or outside to the grounds and lake. Pumping occurs continuously but has suffered from clogging due to iron ochre. Power outages have resulted in basement flooding in the past and a stand-by generator system is currently in place that will keep pumps continually running to remove the water. If the power or pumps were to fail, it only takes one hour for the basement to flood. Even with the power and pumps operating well, and no storm or rain events exacerbating conditions, water regularly seeps through a long crack in the basement floor slab due to hydrostatic pressure. Also a concern, the main sump pump discharge outlet, which is located in the seawall at the Coast Guard basin, will become completely covered at times due to the high lake water level. Complete blockage is especially a risk in the winter if the basin water freezes.

The Government has had multiple waterproofing companies come on site to investigate and give repair estimates to solve the problems. The recommendations varied with them ranging from comprehensively revamping the current passive groundwater removal system to filling cracks.

One local wet basement repair contractor came out to investigate the crack and water seepage problem. The water pressure under the slab was measured at 30 psi. Their recommended solution was to cut a new trough in the basement floor to connect the crack to an existing trough in the basement that runs to the sump pumps. This was close to being pursued before doubts arose about its effectiveness. The Government is concerned that cutting a trough in the slab may just worsen the situation and create a major flooding event. Staff walking on the basement slab next to the crack have indicated that the slab actually moves up and down and is unstable. This could become problematic for safety and structural reasons. If a trough is cut and weakens the slab then there is the possibility of introducing more water out and onto the floor and destroying the contents, equipment, and infrastructure. Also, electrocution concerns are heightened. Further, a cavity could be under the slab at this point that could possibly undermine the existing foundation footings and/or walls if abruptly disturbed.

Due to the varied recommendations and unclear path forward, the government procured an engineering assessment contract that outlined the issues and gave options to permanently fix the situation in order to ensure the safety of personnel and integrity of this historic building. A local engineering company, who conducted the assessment, recommended the basement floor slab to be raised. To accomplish this, the building will need to be raised and the foundation underneath reconstructed. The desired basement floor slab elevation raise magnitude is 3 feet in order to prevent future groundwater infiltration issues.

SCOPE OF WORK

The Contractor is responsible for raising the elevation of the basement floor slab by 3 feet which will include lifting the building and reconstructing the underneath foundation. As well, the utilities in the basement will need to be moved. Essentially, the entire building, including the foundation is to be raised 3 feet.

The tasks are as follows;

1. Raise building structure sufficiently to allow for the reconstruction of underneath foundation and an increase of the basement foundation level by 3 feet.

2. Reconstruct basement floor slab foundation and elevate floor by 3 feet.

3. Move all utilities before elevation and reconnect after elevation to include replacing the main water pipe leading from building 1 to the street.
