Site work and renovation of a parking garage in Columbia, Missouri. Completed plans call for the renovation of a parking garage; and for site work for a parking garage.

Nabholz Construction is the Construction Manager at Risk (CMR) and is hereby requesting qualifications from companies with expertise designing and installing grouted micropiles for existing structures. This is step one of a two-step process with the intent to engage multiple firms for preconstruction and design and ultimately have a single firm perform the full scope of the project. We anticipate 2-5 firms will be short-listed in this Step 1. Preconstruction services and costs will be negotiated with each short-listed firm for their engagement in the Design and Scope Development Phase of the project. Following completion of the Design and Scope Development Phase, the short-listed firms will be issued a RFP for the full scope of the Grouted Micropile Bid Package. The single firm providing the best value to the owner at conclusion of Step 2 will be selected to complete the scope of work. The project (including scopes beyond this package) will include underpinning approximately ninety-three column foundations using grouted micropiles. This will require the demolition and excavation of the ground floor slab adjacent to all columns. The micropile installation will require the temporary relocation of the current finished space on the ground floor of the parking structure. In addition to underpinning, this project will address all outstanding maintenance repairs in the garage. Repairs will include repairs to double tee connections and bearing pads, partial depth concrete repairs, installation of traffic membrane, sealant replacement and expansion joint replacement. The parking structure will be closed throughout the underpinning and maintenance repair project. The scope of work for this package is specific to any required grouted micropiles and potentially any required pile caps. Other scopes are excluded from this package and will be bid separately (i.e. demolition, concrete restoration, maintenance, etc.).
