5th Street / 6th Street Improvement Project

City of Los Angeles, Department of Transportation

Los Angeles County Metropolitan Transportation Authority

Outstanding Bikeways and Trails Project


The 5th Street / 6th Street Improvement project was implemented through a multi-agency partnership between the City of Los Angeles and Los Angeles Metro to reduce congestion, improve mobility & increase safety on local streets/corridors in DTLA. The project installed new part-time dedicated bus lanes on the right side of both 5th and 6th Street between Central Ave and Hope Street, and new protected (Class IV) bicycle lanes on the left side of both 5th Street and 6th Street between Central Ave and Spring Street. The LADOT design team included innovative and much-needed safety features as part of this project, such as cat-tracks through intersections, a wide striped safety buffer on both sides of the bicycle lanes, new high-visibility crosswalks, and unique bikeway transitions at the project limits. The project reallocated a travel lane and off-peak parking lanes to become transit-only lanes during the hours of 7 AM to 7 PM Monday-Friday.


5th Street and 6th Street are one-way streets and together they establish a major east-west transportation corridor through the urban core. This connection links Skid Row, Central City East and the Arts District to the rest of Downtown’s growing active transportation network, and to jobs, resources and high-quality transit such as Metro Rail.


The project was developed through coordinated efforts: 5th and 6th were identified for transit prioritization by a Bus Speed Engineering Working Group authorized by Metro Board & Los Angeles City Council to support implementation of the Metro Los Angeles NextGen Bus Plan; and a community-driven organizing effort led LADOT to prioritize and seek funding for bicycle/active transportation enhancements on these streets. Lastly, LADOT, Metro and StreetsLA (the Bureau of Street Services) worked together closely to improve the road surface condition to ensure a smoother ride for everyone.

SoFi Stadium

SoFi Stadium and Hollywood Park

Outstanding Architectural Engineering Project


Completed in the September of 2020, SoFi Stadium is the home to two NFL teams, the Los Angeles Rams and the Los Angeles Chargers. The stadium seats 70,000 and can be expanded to 100,000 for special events. The 3.1 million-square-foot landmark is an architectural and engineering marvel with innovative engineering and construction solutions. This enormous and complex project, was delivered by multiple prime contractors, designers, engineers, surveyors, and approving agencies, established numerous industry firsts.


Located on the former Hollywood Park racetrack, the stadium is just 500 yards from an active seismic fault. With the site on the flight path to LAX Airport three miles away, the playing field was driven 100 feet into the ground. A record-breaking 100-foot tall mechanically-stabilized earth (MSE) wall creates a moat around the entire stadium, giving it room to safely move during a seismic event. An advanced structural system featuring buckling restrained braces and lock-up devices provides needed lateral strength. SoFi Stadium’s sinuous semi-transparent roof canopy -supported by the largest double cable-net system in the world - rests on a massive asymmetric steel compression ring that is in turn supported atop a system of (38) 150-ft segmental concrete columns outside of the MSE wall. The canopy includes 46 micro-operable openings to help maintain a comfortable environment for fans as an outdoor experience. The canopy columns are supported on a complex soil-isolated foundation system that extending outwardly from the stadium, in some locations extending under the adjacent public roads.


Considered separate from the stadium yet nestled under a portion of the stadium’s roof canopy, is a 6,000-seat performance venue. Surrounding the stadium, a master-planned community will include 2,500 residential units and 25 acres of public parks, and open space. Parts of the remaining area have been set aside for retail, office and residential components, a 6-acre lake amenity.

Broadway Palace Apartments

G.H. Palmer

Outstanding Urban and Land Project


Broadway Palace Apartments is an urban infill mixed-use podium and tower development located at 928 and 1026 S Broadway. The 4.1-acre project spans across two blocks and consists of two buildings, which include 686 apartments with 17 live/work units and over 50,000 SF of retail space. The south building is a seven-story timber structure with three subterranean parking levels while the north building is a combination of a seven-story podium timber structure and an 11-story steel tower with 4-levels of subterranean parking. Together the buildings provide over 800 bicycle spots and over 1,400 parking stalls. The project included an alley vacation, realignment of a public sewer main crossing the site, public street and sidewalk improvements, and subterranean drywell systems located within the building footprints.


The project architect created the design to match the Beaux-Arts architecture of the historic Broadway corridor in Downtown LA. This required the Broadway elevation of the north building to be designed as a mid-rise structure, to match the historic appeal, while the remainder of the building was designed as a low-rise structure. Additionally, the building was designed to maintain public visual access to a culturally significant Banksy street art exhibit on the adjacent building.


This project incorporates the use of innovative stormwater sustainability via interior subterranean drywell systems located within the building envelopes under the subterranean parking levels.

Construction documents were prepared to achieve meet local LID BMP requirements to infiltrate stormwater onsite within building structures that extend from property line to property line. Drywells were successfully located to limit the effect on required parking spaces, accommodate access for maintenance, and accommodate the plumbing engineer’s interior pipe network routing. The drywell pipe routing system within the building was designed to overflow the site BMPs/Drywells to the public street elevation, without the use of pumps when the BMP’s had to be located several subterranean levels below street elevation.


This mixed-use project located on Broadway Avenue, whose design was shaped in large part by the City's Broadway design guide that seeks to maintain the corridor's mid-rise street wall and historic architecture, is the latest installation to the historical, yet blossoming community in Downtown Los Angeles.

A Bridge Home - Sunset - Council District 11

City of Los Angeles - Bureau of Engineering

Outstanding Community Improvement Project


Mayor Eric Garcetti’s “A Bridge Home” plan provides a transitory safe refuge off the streets for individuals experiencing homelessness on the path to permanent supportive housing. The design challenges of providing accommodations for the homelessness on a demanding schedule and limited budget called for design innovations that balanced efficiency with maintaining an environment of dignity and humanity for the users. The Sunset “Bridge Home” Project is a small step in a city-wide effort to combat the large-scale homelessness problem.


The Sunset "Bridge Home" site is an urban-infill project housing 154 occupants located on what was previously an MTA Bus storage facility. The project components consist of a series of prefabricated structures, 60 ft. by 120 ft. tensile membrane "Sprung" structure, 24 ft by 40 ft. residential trailers, a 24 ft. by 80 ft. administration trailer and a 12 ft. by 60 ft. Hygiene trailer. The Sprung structure houses 100 occupants , separating men and women, bifurcated with an open central communal area with ten-foot-high perimeter privacy walls. Two offices for case managers flank either side of the open space at the entries to the respective sides of the men and women. The residential trailers were used for the housing of Transitioned Adult Youth (TAY). a total of 54 beds were allocated to at-risk youth. As a design tool, vibrant colors were incorporated as much as possible, both in the interior and exterior of the facility, primary and secondary gathering spaces balanced efficiency while maintaining an environment of dignity and humanity for the users.

Chevron Cogeneration B-Train Efficiency Upgrade

Chevron El Segundo Refinery

Outstanding Energy Project


The Heat Recovery Steam Generator (HRSG) utilizes discarded heat from the combustion turbine generator’s (CTG) exhaust gas to produce steam for the 850 and 300 psig steam systems. It also provides gas emission controls for the CTG exhaust gasses.

The processed flue gas passes over the High Temperature Economizer (HTEC) tubes where feedwater receives final preheating before entering the HP boiler. The gas continues and passes over the new Low Temperature Economizer (LTEC) tubes where feedwater receives the first pre-heat before being directed to either the MP boiler tube section, or to the HT economizer tubes. This capture of waste heat by the HTEC and LTEC enables additional steam generation (with no additional duty/fuel) which increases Cogeneration efficiency (more steam is generated for the same fuel burned). The estimated duty reduction is ~13 MMBTU/hr or ~7,500 MT CO2 reduced for the same steam generation.

The original LTEC design had 10 rows of tubes in a serpentine design with upper and lower headers. The nature of this design led to large moments where the drains attach to the lower headers and forced the tube bend to accommodate the strain and to yield plastically. Buoyancy instability is present in several rows and was expected to cause plastic deformation in the upper tube bends, particularly during start up and transient conditions. These events led to low-cycle fatigue and tube failures that ultimately led to the decommissioning of the LTEC.

The new, upgraded LTEC design incorporates HRST’s ShockMaster technology and utilizes all up-flow circuits, eliminating the buoyancy instability and inlet-pass thermal shock during both steady-state and transient operating conditions. The HRST design includes no tube bends, acting further to eliminate moments and bending stress at the tube-header connections. The new single-pass panels result in a reduced overall pressure drop and increased reliability will sustain higher efficiency throughout the run of the Cogeneration unit.

Chevron partnered with SoCalGas to participate in the Energy Efficiency Conditional Incentive Program (EECIP) and was one of the leading energy efficiency projects under this program. Furthermore, Chevron is working with the California Air Resources Board (CARB) to submit this project under the Low Carbon Fuel Standard (LCFS) Refinery Investment program.

Crenshaw/LAX Corridor

Los Angeles County Metropolitan Transportation Authority

Outstanding Transportation Project


This project has contributed to the local community in aspects of several different award categories. It sets the stage for the airport's landside access modernization program, such as by building in accommodations for the future Aviation/96th St station that will connect the rail line to the automated people mover between the terminals and the consolidated rental car facility. The underground stations have architectural elements. The project is incorporating future bike lanes. Walsh-Shea Corridor Constructors (WSCC) built several bridges, including one over the 405 freeway. The project has donated to local toy drives and supported local businesses such as Dulan's during construction. This major construction project includes several traction power substations that convert SCE's 16 kV and DWP's 4.8 and 34.5 kV feeds to direct current that will energize the overhead catenary system with 600V DC. The electric trains will operate sustainably without the need for combustion and the associated emissions. The project uses best management practices to protect the environment. The tunnel entrance portals are protected against major floods with grading and sump pumps. The drilling for soldier piles and earth-pressure direction drilling by TBM utilized geotechnical instrumentation to confirm that any settlement was within established limits. It is rejuvenating a boulevard that used to have trolleys.

Its Florence/West Fairview Heights station is within walking distance of a beautiful Inglewood park. It has safely maintained traffic during construction and includes roadway restoration along the alignment. Structural calculations have confirmed that the equipment is safely anchored to pads to withstand earthquakes. Within the megaproject are many smaller projects, such as a pedestrian underpass for the Faithful Central Bible Church. Structural engineering ensured safety for the new bridge passing under the 105 freeway and over Imperial Highway. Quad gates will protect grade crossings in Inglewood against car-train collisions.


The project is spurring urban development along the corridor, including new senior housing south of 54th St. The project includes improvements to the Baldwin Hills mall plaza, including special pavers. The project includes many millions of dollars worth of bringing water meters and fire hydrants into compliance with standards, replacement of several blocks of 24" water main, and new connections for domestic, fire service, and irrigation water services. Each underground station has an oil water separator to treat water before it is released into the City's systems. WSCC has replaced several sewers and cleaned some to the benefit of the City's sanitary system.


Earvin "Magic" Johnson Park Revitalization Phase 1A

Los Angeles County Public Works

Los Angeles County, Department of Parks and Recreation

Outstanding Sustainable Engineering Project


AHBE|MIG, Paul Murdoch Architects (PMA), PACE Advanced Water Engineering and CWE Engineers in collaboration with the Los Angeles County Development Authority (CDA), Los Angeles County Department of Parks and Recreation, and Los Angeles County Public Works (PW)—created a 21st century park that addresses how Southern California might implement the capture and reuse of our stormwater runoff and adds a much-needed amenity to an underserved community.


Earvin "Magic" Johnson (EMJ) Park, the largest open space in South Los Angeles, is an highly complex project and intersects many of today’s environmental, social, and public policies issues. Originally an oil processing site, the Park was bought by the County of Los Angeles as an extremely contaminated site in the middle of one of most politically active communities in the last century - the Willowbrook District of South Los Angeles.

The 120-acre park combines new recreation amenities with green infrastructure. The project includes a new community event center, a lakeside community loop trail with picnic areas and scenic viewpoints, a destination children’s play area, outdoor classrooms, and California Native landscapes.


To minimize potable water use, the Park was re-engineered through collaboration with the CDA and PW to provide a sustainable new water source using a unique stormwater management system to recycle the runoff from the 375-acre watershed. This system captures and treats runoff (dry and wet weather flows) to improve water quality. The stormwater runoff is then directed to a biofiltration area in the form of mitigated wetland surrounding one of the park’s two lakes. The filtered stormwater water fills the lake and is then recirculated to irrigate the Park. In addition, the wetland creates a habitat for birds, insects, and other urban wildlife.
