What We Do
Rock City Construction Co. (RockCity) holds Tennessee Contractor’s License #2, the oldest active license in the state of Tennessee. Our core competencies are listed below; we have performed successfully under many contract types and delivery systems.
As a general contractor, we provide management of the project and field supervision, typically self-performing approximately 30% of the work, often inclusive of carpentry, concrete, installation of frames, doors, hardware and some specialties. All other trade work is subcontracted to properly licensed and expertly qualified trade contracting firms.
In general contracting, the owner holds a contract with the architect and a separate contract with the general contractor; construction documents are typically prepared before selection of the general contractor. There are several contract types applicable to this owner-contractor relationship including lump sum, cost plus fee and maximum guaranteed cost plus fee.
As construction manager, our team provides extensive pre-construction services during the design phase as required by the contract with the owner, and transitions into construction-phase management that includes most aspects of general contracting except often limiting self-performance to 3% or less.
In construction management, the contract structure between owner and architect and contractor are similar to general contracting, but the contractor is involved earlier in the project, providing pre-construction services during the design phase, and leading the trade bidding process when construction documents are complete. There are several contract types applicable to this owner-contractor relationship including lump sum, cost plus fee and maximum guaranteed cost plus fee.
The design/build delivery method is inherently collaborative; with this method, our team becomes involved in the project at the onset of pre-design or programming. We select the design team and lead the team as the client’s single source of responsibility. In this scenario, the construction team is united with the design team by common goals and constant collaboration, utilizing construction expertise in the design phase.
In design-build, the owner holds one contract – with the design-builder. While the owner may lead or participate in architect selection, the architectural firm holds a contract with the design-builder. Besides differences in contractual relationships, design-build requires much earlier involvement of the contractor than other delivery methods. There are several contract types applicable to this owner-contractor relationship including lump sum, cost plus fee and maximum guaranteed cost plus fee.
Pre-construction as a stand alone service could include budget planning, schedule forecasting, and preliminary value engineering services.
