Westside Purple Line
The Purple Line Subway extension proposes tunneling extension from Wilshire/Western Avenues to West Los Angeles and University of California, Los Angeles (UCLA). DLCE has taken a major role in the development of the project’s utility master plan. This included the relocation of utilities for major utility companies in the City of Los Angeles (Department of Water and Power, gas and electric private companies). Tasked included the preparation of engineering design drawings for all major underground stations. Additionally, our company prepared engineering designs for the following stations: Rodeo Drive, Constellation/Avenue of the Stars and Westwood/UCLA which includes underground boxes structural analysis and design, track alignment, utilities, street reconstruction and CAD automation support.
Eastside Light Rail Line (Phase 1 & Phase 2)
Los Angeles, CA
The Eastside Light Rail Line is a transit corridor connecting Downtown Los Angeles to East Los Angeles communities. Phase 1 of the Eastside project was an light rail extension from downtown Union Station to East Los Angeles/Atlantic Avenue. The Eastside Transit Corridor Phase 2 is a planned transit corridor connecting Downtown Los Angeles by extending the Gold Line in East Los Angeles to San Gabriel Valley cities of Los Angeles County. For Phase 1 of the project, DLCE performed environmental planning and engineering for a number of structures along Washington Boulevard and the State Route 60 alignments. DLCE is continuing the engineering for Phase 2 project including utility identification and third-party coordination with East Los Angeles County corridor cities.
Crenshaw/LAX Light Rail Line
Los Angeles, CA
The Crenshaw/LAX Transit Project is a 8.5 mile long light rail project consisting of one mile underground tunnel, at-grade and cut-and-cover construction. It will serve Crenshaw Boulevard corridor, South Los Angeles and Westchester communities along with the Los Angeles International Airport (LAX). The project consists of 8 stations, a maintenance facility, park-ride lots, traction power substations and the acquisition of rail vehicles and maintenance equipment. The new rail stations will be Expo/Crenshaw, Crenshaw/Martin Luther King, Crenshaw/Vernon (Leimert Park Village), Crenshaw/Slauson, Florence/West, Florence/La Brea, Florence/Hindry and Aviation/Century. DLCE played a key role in providing civil engineering services for track design, street and road improvements at over 12 crossings, grading, drainage utilities, ADA access, parking lots and stations. Our company provided civil engineering support to HNTB, the prime designer on a number of engineering tasks.
Exposition Light Rail Line (Phase 1 & Phase 2)
Los Angeles, CA
The Metro Expo Line connects West Los Angeles by rail to Downtown Los Angeles, Hollywood, the South Bay, Long Beach, Pasadena and dozens of points in between. This light rail project extends 8.6 miles, 12 stations and includes three Park & Ride lots from Downtown Los Angeles (Metro Center at 7th & Flower Streets) to Culver City in West Los Angeles. DLCE’s was responsible redesigning major utility lines and coordinated with the design-build contractor on utility identification pot-holing. Our company took the lead role on producing a majority of engineering plans through 100 percent design levels. DLCE was also responsible for street improvements designs and plans, roadway reconstruction at the rail crossing at: Vermont Avenue, Western Avenue, Crenshaw Boulevard, and Fairfax Avenue. Our staff prepared construction drawings with the latest civil engineering software.
Foothill Gold Line Phase 2A
Los Angeles, CA
The Foothill Gold Line extension is a 8 mile light rail line spanning from the City of Pasadena to the City of Azusa (parallel to the State Route 210 Freeway). The Project begins just east of the existing Metro Gold Line Sierra Madre Villa Station in Pasadena and runs along the former Burlington Northern Foothill Extension which connects the cities of Arcadia, Monrovia, Duarte, Irwindale and Azusa. DLCE’s staff was responsible for the design and development of grade crossing designs and the preparation of California Public Utilities Commission (CPUC) street grade applications. Staff also provided engineering support during the project’s construction phase for a number of structures including: Sierra Made Bridge and a number of retaining walls. DLCE also worked closely with the design-build contractor to oversee the development of the Monrovia rail vehicle storage facility.
Downtown Regional Connector Project
Los Angeles, CA
The Regional Connector is a 1.2 mile transit project in downtown Los Angeles extending from Metro Center station (7th Street/Flower Street) to the historic Little Tokyo district. The Regional Connector will provide an important link the existing Gold Line and Exposition light rail lines. DLCE provided support services for the all underground alignments (tunnel and underground stations) along Flower Street and Hope Street all the way to Alameda Boulevard (Little Tokyo). Prepared and identified all major utilities including: gas, water, power, storm drain, sanitary sewer and communication lines to accommodate relocation.
Red Line Subway (Minimum Operating Segments 1, 2, 3)
Los Angeles, CA
The Red Line was the first subway line servicing Los Angeles County that connects Downtown Los Angeles (Union Station), Hollywood and North Hollywood (NBC Universal). The Red Line, which is one of six lines forming the Metro Rail rapid transit system opened in phases between 1993 and 2000. Together with the Purple Line, these two heavy rail lines combine to form L.A. Metro Rail’s busiest line. Today, combined, both the Red and Purple lines average close to 180,000 boardings per weekday. The Red Line subway system consists of twin tunnels lined with concrete segments excavated using Tunnel Boring Machine (“TBM”) and Earth Pressure Machine (“EPM”) excavation systems. DLCE took a major role for the design of stations along with utility relocation and roadway reconstruction.
Link Union Station & High-Speed Rail Project
The California high-speed rail system will eventually create over 800 miles of rail, with up to 24 stations. DLCE took an active role in the investigation and identification of existing utilities along 30 miles of future track alignment between the cities of Burbank and Anaheim. The utility investigation emphasized its focus at over twenty five grade separations in a number of Los Angeles and Orange County cities. DLCE investigated all potential conflicts with a number of proposed alignments and systems along the High Speed Rail corridor. DLCE engineers worked with a number of utility companies for the preparation of utility reports. This included: Major gas companies, Power (Department of Water and Power, Southern California Edison and numerous cities), the City of Los Angeles Bureau of Engineering, Bureau of Sanitation, the Los Angeles Department of Transportation, County of Los Angeles Flood Control, and telecommunications providers (Verizon, ATT, Sprint, XO Communication, Warner Cable).
