2.0 - General

2.1 – Background One slab of the shop floor has shifted to the point of creating hazardous walkway. The slab has a vault with stairs that is designed to function as a mechanic service walkway. This vault has shifted to the point it may affect stability. The outside walkways have deteriorated due to insufficient drainage and water damage. There is also a section that has heaved outside the main door which limits the door from opening fully.

2.2 – Purpose The east foundation slab in the shop has lifted and cracked around the concrete vault/vehicle maintenance pit in the middle of the slab. It appears that freeze-thaw from moisture under the slab is the cause of the lifting. The issue at the shop slab appears to be indicative of a wider drainage issue in the area of the Alamosa shop building. The Alamosa office and shop building area appears to be at a lower elevation than the surrounding land, which causes runoff to flow to and pond at various spots on the property.

2.3 - Scope The slab on the right side of the Alamosa shop building needs to be removed and replaced, an estimated 800-ft2 area and 18-inch-thick slab. The vault in the middle of the slab can either be removed or left in place; either way the open space would be filled and compacted. The vault dimensions are 26.25 ft. long x 3.4 ft. wide x 5.2 ft. deep (464 ft3). To prevent future moisture accumulation that could lead to another damaging freeze-thaw effect, a subsurface drain to draw water away from the shop foundation could be installed. Also recommended is to improve the overall drainage scheme of the paved areas around the shop building. This could include removing the drain at the disused wash bay and paving it over and repaving other areas so that runoff flows away from high traffic areas where it could otherwise freeze over and become a hazard. There are existing drains in the gravel parking lot area that the new drainage scheme can flow to. The heaving area outside the north entrance of the shop will need to be removed and replaced. The perimeter sidewalks will need to be repaired or replaced along with deteriorating sidewalk aprons.

The following Photographs are provided for as reference only.
