LANL PF-10 and PF-11 Diesel Generator
LANL PF-10 and PF-11 Diesel Generator
Client: Los Alamos National Laboratory (LANL)
Location:
Lopez Engineering, Inc. (LEI) was the Prime Consultant and was using the ARES Corporation for Structural Engineering for this project. LEI provided the design for new safety class diesel generator(s) and support systems required to provide back up power to the PF-10 and PF-11 electric fire pumps including housekeeping pads, automatic transfer switches, conduit runs, supports, trench details, diesel fuel storage tank(s), engine cooling system(s), PC-3 calculations, etc. as required. Design includes NQA-1, safety class diesel generator(s), 60 minute fuel supply, automatic transfer switches, engine cooling systems, and other support systems as required to provide backup power to the PF-10 electric fire pump and PF-11 electric fire pump. Work includes on-site walk downs inside the TA-55 protected area.
The LEI Team provided frequent verbal and written communication with Los Alamos National Security (LANS) for this project. Verbal communications consisted of conference calls every other week or more frequently as required by LANS. All formal correspondence was sent under the signature of the LEI and ARES Project Managers and the LEI contract administrator. Informal correspondence (verbal, e-mail, etc.) is recorded and controlled as appropriate. Other correspondence such as meeting minutes, incoming direction, etc., is controlled to ensure appropriate configuration control.
LEI performed Power Studies (Short Circuit, Voltage Drop, Overcurrent Coordination, and Arc Flash) using SKM Power Tools software and sized the engine generator using commercial software. LEI has verified and validated both of the software programs with hand calculations.
This work was Quality Affecting and was being performed in accordance with the LEI Quality Assurance (QA) Program. This QA Program was previously approved when LEI was placed on the LANS Institutional Evaluation Subcontractors List. LEI’s QA Program meets all applicable requirements of DOE O 414.1C, Quality Assurance, as required in the LANS Statement of Work. This QA Program, coupled with our previous experience with the LANL configuration management requirements, ensured proper configuration control and records management.
Submittals consisted of 60%, 90%, 95%, and Final with a two week review period for LANL, which review period produced a formal Design Review Record to which the LEI team responded. Submittals included drawings, specifications, calculations, construction bill of materials (LANL used this as input to prepare their own cost estimate), schedule of special inspection, and test and inspection plan.
