Client: Los Alamos National Laboratory (Triad National Security)

Location: Los Alamos, New Mexico

LEI provides Electrical Design and Quality Assurance Procedures for the Northern New Mexico Architects and Engineering Group (NNMAEG), a Joint Venture design firm with an IDIQ contract for Los Alamos National Laboratory.  

The NNMAEG partnered with Jaynes Corporation for two Design/Build projects for a 144,520 sq. ft, three level parking structure at Technical Area 03 and 140,761 sq. ft, three level parking structure at Technical Area 50 at the Los Alamos National Laboratory.  The project will provide a parking garage within safe/secure walking distance to the NSSB/Otowi TA-03 Area and TA-35, TA-50, and TA-55 areas. 

Over the past three years, LANL has experienced significant growth in terms of overall staff and contractors. The existing supply of parking, both in surface lots and in parking structures, is not adequate for the increased activity at LANL.  

The new parking structure at TA-03 area will provide an additional 467 spaces, which include 435 standard spaces, 6 motorcycle spaces, 11 ADA compliant spaces, 2 ADA Van compliant spaces, 4 HOV spaces, and 9 Electric Vehicle spaces.  The new parking structure at TA-50 area will provide an additional 455 spaces, which include 423 standard spaces, 6 motorcycle spaces, 11 ADA compliant spaces, 2 ADA Van compliant spaces, 4 HOV spaces, and 9 Electric Vehicle spaces.  Electrical Design included provisions and spare capacity for up to 21 additional future Electric Vehicle spaces for each building.

For TA-03 area, LEI performed Site Investigations of existing 15kV ductbank and telecommunication ductbank and manholes, which would need to be relocated to accommodate the new structure.  A sequence of construction was also developed to support relocated an existing chiller.

For TA-50 area, LEI performed Site Investigations of existing 15kV ductbank and telecommunication ductbank, to determine a new point of connection for Power and Telecommunication service.  Due to the project location near a canyon with migratory bird nesting areas, the lighting design utilized full cutoff fixtures mounted at lower heights along building walls overlooking the canyon to minimize lighting trespass.

The new/modified electrical distribution system was modeled using SKM Power Tools for Windows to calculate the fault current, feeder voltage drop, arc flash incidental energy, and the overcurrent protective device coordination. Visual Lighting software was used to calculate photometric reports for normal and egress lighting.  An NFPA 780 Lightning Protection Risk Assessment was also performed for the new structure.

The Construction Drawing set includes Site Plans, Power Plans, Telecommunication Plans Single-Line Diagram, Parking Guidance System Wiring Diagram, Schedules, Trenching Details, Transformer Containment Pad Details, Equipment Elevations.  LEI also completed Construction Specification Sections.

LEI provides Construction Administration to attend construction coordination meetings, review electrical submittals, answer Requests for Information (RFIs), perform periodic Site Observations, and prepared As-Built Record Drawings.
