PROJECT DESCRIPTION
For this design-bid-build firm fixed price contract SCS acted as the general contractor as well as self-performed the following trades; demolition, mechanical piping, ductwork, electrical, and equipment installation.
This project’s scope of work included the installation of a new 80,000 CFM located on the second floor roof which included chilled water coils, steam humidifier, and steam heating coils. In order to support the new unit and entirely new structural steel platform was erected completed with stairs and walk ways around the exterior. Once the unit was installed a new mechanical penthouse was constructed around the AHU to protect the AHU and associated systems from the elements. This project also included the removal and installation of a 21,000 CFM indoor central station AHU. Additional work included the installation of 97 new single coil VAV’s on two entire floors of the main hospital with services to admin areas, patient rooms, CLC, laboratories, and surgery suites. New supply ductwork was installed throughout the two five renovated floors to allow the existing dual duct system to be converted to a supply and return ductwork system. Additional work included the installation of heating hot water piping system to supply heat to the new VAV’s. The heating hot water system was supplied with heat through the installation of a steam to hot water system heat exchanger system which included parrell heat exchangers, parrelll pumps, and HVAC DDC. Work included the removal and replacement of ceiling, installation of new lights, partition walls, drywall, paint, roofing patch and repair, core drilling, fire chaulking, and large scale abatment of ACM pipe insulation and duct mastic. Additional work also included the installation of new DDC controls for all installed equipment including AHUs, pumps, heat exchangers, VAVs, and glycol systems. All new equipment was equipped with VFDs drives to ensure that all equipment will operate at max efficiency given the building loads. Lastly, new fire alarm devices, FACPs, and plumbing was installed to support the new VAVs and AHUs. In all, over 60,000 SF of hospital floor space was renovated.
The experience gained and techniques used in completing this construction project is extremely relevant to the scope and complexity found in this particular construction project. The following is a summary of this project’s relevancy to the proposed RFP: Work in an occupied VA Medical Facility, integration of HVAC systems into a facility, integration of HVAC DDC & BMS systems, removal and replacement of AHUs, installation of new AHUs, temporary air, Phased construction schedule – ensured continuity with existing operations, 3 Phase USACE Quality Control QC which included preparatory, initial, and follow up. Applied EM 385 Safety Program throughout project, chilled water systems, heating hot water systems, steam systems, Installation of ICRA containment and negative ventilation. This project also falls within the relevant price range and is very similar in size and complexity to what we anticipate to see on task orders for this RFP.
In total, SCS self-performance model yielded SCS self performing 90% of the project’s scope of work. The only significant portions of work sub contracted were as follows: HVAC DDC, Roofing, Structural Steel, ACT, abatement, and drywall.
