 4LEAF provided Project Management services for Sacramento Regional Transit District’s Downtown-Natomas-Airport (DNA) Minimum Operable Segment 1 (MOS-1). The MOS-1 is the first segment of an approximately 13 mile-long Light Rail Extension that will ultimately connect the existing line to the Sacramento International Airport. The project began at the existing line terminus in Downtown Sacramento and extended along 7th Street between the Alkali Flat Neighborhood and ended at Richards Boulevard between 6th and 7th Streets. The MOS 1 involved the construction of a one-mile extension of the current Light Rail system, the construction of one new station at the terminus, and the potential modification of several existing stations. The project also included trackway, an overhead catenary system (OCS), a Traction Power Substation, railroad signalization, and traffic signalization.

 4LEAF, Inc. provided full service Construction Management and Construction Inspection services for this project that included an important extension of Sacramento's light rail transit (LRT) system. This extension was significant because it links the Light Rail Transit system to Amtrak's Capital Corridor rail services and longer-distance national network trains. The project included construction of an approximately half-mile section from 7th and K Streets to Amtrak's intercity rail passenger station, the overhead catenary system, and three new stations.

 4LEAF was the Inspector of Record (IOR) and assisted with Project Management for the construction of the MUNI Metro East LRV Maintenance & Operations Facility. The Metro East Light Rail Maintenance and Operations Facility is located on a 17 acre site and provides storage and maintenance of Light Rail Vehicles (LRV’s) serving the Third Street Light Rail Line. The goal of this project was to improve the overall Metro delivery system by relieving the overcrowding at Metro Green/Geneva, MUNI’s only other maintenance and repair facility for LRV’s.
This signalized and electrified yard provides storage for 80-100LRVs as well as an automatic train control (ATC) test track. The main shop provides facilities for daily vehicle servicing (inspection, fare extraction, sanding, interior cleaning, and exterior washing), preventive maintenance and running repair (trestle tracks over depressed floors with roof access catwalks), wheel truing, heavy repair (LRV hoisting, de-trucking, and component repair), central stores, and maintenance and transportation worker support facilities. The paint and body shop provides two downdraft booths for prep and painting as well as three tracks for body work and frame straightening.

4LEAF provided inspector of record (IOR) services and assisted with project management for the construction of the new infill Bay Area Rapid Transit (BART) Station and two parking structures at West Dublin/Pleasanton. The new station was the first to be built on an existing BART line and first designed with an integrated transit village. The two parking structures were constructed, one in each city. The structure in West Dublin was a five-story parking structure with 714 stalls and the parking structure in West Pleasanton was five-story and had 470 stalls.
