Many transit systems historically relied on design-bid-build, where a project is designed, competitively bid, and then constructed. While this model offers clear roles and pricing transparency, its sequential process can lead to delays when constructability challenges or unforeseen conditions emerge during construction.

To address these challenges, agencies are increasingly adopting alternative delivery methods such as design-build, construction manager/general contractor (CMGC), progressive design-build (PDB), and public-private partnerships (P3). These approaches bring contractors into the process earlier, allowing teams to identify risks sooner and make more informed decisions.

LA Metro selected PDB as the primary delivery method for the ESFV LRT project. In this model, the design-build team is engaged before the design process is complete and works collaboratively with the owner to refine scope, schedule, and cost as the design advances. The process typically unfolds in two phases: an initial phase focused on design validation and risk management, followed by final design and construction.

For complex urban rail programs, this structure allows for earlier contractor input, improved constructability, and stronger coordination across agencies and stakeholders.

Underground utility conflicts are a frequent challenge in urban rail construction. To reduce this risk, the ESFV LRT effort prioritized EWPs and subsurface investigations during preliminary engineering. LA Metro collaborated with the City of Los Angeles and utility owners to ensure that self-performed improvements, including utility adjustments unrelated to the project, were reviewed by the project team to avoid potential conflicts with future project improvements.

Stations, guideway infrastructure, and utility relocations were advanced to 60% design level, and eight strategic utility relocation packages were developed from concept to final design and construction approval. Investigations using ground penetrating radar, potholing, and trenching helped identify underground infrastructure and reduce uncertainty.

More than 23,000 linear feet of underground power and waterline relocations were advanced early to support construction readiness. As final design advances, the project team anticipates awarding the Phase 2 construction contract in mid-2026, positioning the program to transition fully into major construction activities.

Coordination with agencies, including the City of Los Angeles, Caltrans, Los Angeles Department of Water and Power, Southern California Gas, and various telecommunications providers, was essential throughout this work. LA Metro also established an Integrated Project Management Office (IPMO) to support collaboration among designers, contractors, and agency partners.

Delivering a new rail line along Van Nuys Boulevard requires close coordination with residents and local businesses. LA Metro has prioritized outreach through quarterly construction update meetings, bilingual construction notices, and engagement with more than 40 community organizations.

To support businesses during construction, LA Metro created several programs:

• The Business Solution Center provides advisory services and technical assistance.
• The Business Interruption Fund offers financial support to small businesses affected by construction.
• Eat Shop Play promotes businesses along the alignment through marketing and outreach.

The ESFV LRT effort highlights several lessons for agencies delivering large transit infrastructure programs. Early coordination with utilities, regulatory agencies, and community stakeholders helped confirm requirements and reduce potential delays. Advancing utility relocations early minimized schedule risk, while strong coordination across project partners improved decision-making.

Establishing an IPMO further strengthened collaboration by bringing together LA Metro staff, designers, contractors, and agency representatives in a shared environment.

Early engagement with LA Metro real estate, the PDB contractor, and the design teams to assess permanent and temporary easements as well as property acquisition needs helped expedite access negotiations and collectively identify mitigation measures to minimize impacts to business and property owners.

As cities continue investing in public transportation expansion, the ESFV LRT project demonstrates how alternative project delivery methods in infrastructure, particularly progressive design-build projects, can support stronger collaboration, improve project risk management, and lead to more predictable outcomes.
