Our work was installed to NQA-1, ASME N-509, SMACNA, ASME Boiler Code Section IX, and ASME B31.3. The design was performed by Jacobs Engineering. The risks involved a project that had to pass rigorous QA QC requirements in order to pass an NRC level type inspection (which also required extensive record keeping). All specifications and drawings were provided by the designer, and we tracked and worked thru the installation of over 1,500 technical drawings. The cost was tracked by a cost loaded schedule, that maintained a schedule of values. The changes to the project were logged and priced in an expeditious manner. The commissioning was performed thru the shop drawing process, submittal process, QA process, to the pre-functional checklists, to the functional performance test to commissioning, the handover to operations.



Alstom Power Turbomachines

ake Marshall, LLC. performed Mechanical installation for the Alstom Power Turbomachines project in Chattanooga Tennessee, and campus projects relevant to this mega project. We performed off site fabrication and on-site installation of numerous mechanical systems for the facilities. We worked with the clients engineering teams to work out and issues in a timely manner they arose.

 Our staff was as many as 10 office staff, with as many as 185 field craft (counting subcontractors). All craftsmen we trained to perform the work that was required, and had training certificates where required for specific tasks. We had six subcontractors that worked under our direct supervision. We performed our work to a Primavera, man-power loaded schedule. We had a Quality Control Staff that operated and reported to the Quality Assurance Staff that was directed by the client. Our subcontractors were Testing and Balance, Controls, Insulator, Water Treatment, DDC Electrical, and Scaffolding. Our work was installed to SMACNA, ASME Boiler Code Section IX, and ASME B31.3. The design was performed by Larson & Darby Engineering. 

The risks involved a project that had to pass rigorous QA QC requirements in order to pass an LEED Building Gold inspection (which also required extensive record keeping). All specifications and drawings were provided by the designer, and we tracked and worked thru the installation of over 300 technical drawings. The cost was tracked well maintained a schedule of values. The changes to the project were logged and priced in an expeditious manner. The commissioning was performed thru the shop drawing process, submittal process, QA process, to the pre-functional checklists, to the functional performance test to commissioning, the handover to operations, and then an extensive preventative maintenance period.

Wacker Chemie – Polysilicon

Jake Marshall, LLC. performed Mechanical installation for the Wacker Chemie project in Charleston Tennessee, and campus projects relevant to this mega project. We performed off site fabrication of 33,000 pipe spools, and on-site installation of numerous mechanical systems for the facilities. We worked with the clients engineering teams to work out and issues in a timely manner they arose. 

Our staff was as many as 30 office staff, with as many as 360 field craft (counting subcontractors). All craftsmen we trained to perform the work that was required, and had training certificates where required for specific tasks. We had four subcontractors that worked directly for us, and seven subcontractors that worked for the site construction manager that we manager under our direct supervision. We performed our work to a Primavera, cost loaded, man-power loaded schedule that reported daily performance by feet of pipe, insulation wire, and component installation. We had a Quality Control Staff that operated and reported to the Quality Assurance Staff that was directed by the client. Our subcontractors were Testing and Balance, Insulator, Electrical, and Scaffolding. 

Our work was installed to SMACNA, ASME Boiler Code Section IX, NECA, and ASME B31.3. The design was performed by Jacobs Engineering and AEED Engineering. The risks involved a project that had to pass rigorous QA QC requirements in order to pass very high purity sampling of each process system (some to .0000000001 purity %) (of which also required extensive record keeping and extensive management of supervision and commissioning teams). All specifications and drawings were provided by the designer, and we tracked and worked thru the installation of over 23,500 technical drawings. The cost was tracked well maintained a schedule of values. The changes to the project were logged and priced in an expeditious manner. The commissioning was performed thru the shop drawing process, submittal process, QA process, to the pre-functional checklists, to the functional performance test to commissioning, cold commissioning, cold commissioning completion, testing/sampling, hot commissioning, hot commissioning completion, sampling, start-up, the handover to operations, and impurity mitigation.

Memorial Hospital Central Energy Plant, and 7 story Addition

Jake Marshall, LLC. performed the prefabrication and installation of this complex project. Due to critical schedules, and limited space, we performed BIM Modeling and coordination for the project. We worked closely with the clients commissioning agent and the clients engineering firms. 

This project included the installation of 5 large new chillers, their cooling towers and pumps for the new central energy plant. Upon completion of the new central energy plant, we started the process of decommissioning 9 separate mechanical rooms, and changing the cooling load over to the new central plant. This involve over 30 hot-tap tie-ins that were required in order to keep the hospital functioning and without shut-downs. As each of the existing mechanical rooms were decommissioned, we removed their respective chillers, cooling towers, piping, and pumps. Additionally, new generators were installed at the central plant, and after commissioning and load testing, the existing generators were decommissioned and removed. 

At the time that the new central plant was on line and operational, we started the installation of the new 7 story addition to the hospital. This new addition consisted of the installation of 8 mechanical room and their air handling equipment. The project used approx.. 685,000 # of prefabricated ductwork that we had built and staged in our warehouse (all prior to the install).
