Critical Plumbing Infrastructure Built for Complex Construction

AR&B installs commercial plumbing infrastructure with the precision, coordination, and field discipline that complex Bay Area construction projects demand. From Design-Build construction and ground-up development to tenant improvements, retrofits, and infrastructure upgrades, AR&B combines local experience, construction judgment, and disciplined field execution.

For more than 100 years, AR&B has helped build the plumbing infrastructure supporting some of the region’s most demanding commercial environments.

Design-Build Plumbing Construction

AR&B brings engineering coordination, constructability review, prefabrication, and field installation together early in the project. Early collaboration helps identify conflicts, improve installation sequencing, protect the schedule, and create a stronger connection between design intent and field execution.

Complex Commercial Plumbing Systems

Commercial plumbing construction extends far beyond domestic water distribution.

Underground utilities, sanitary waste and vent systems, storm drainage, natural gas, water heating, booster pumps, backflow prevention, and mechanical room infrastructure require careful planning and close coordination across trades.

AR&B provides the project management, field supervision, and installation expertise required to execute these systems in technically demanding environments.

San Francisco Fabrication

AR&B operates a 24,000-square-foot fabrication facility in San Francisco supporting plumbing prefabrication, material staging, and project coordination.

In-house capabilities provide greater control over quality and scheduling while reducing field installation time and dependence on outside fabrication partners.

Built for San Francisco

Dense urban jobsites, aging infrastructure, limited mechanical space, seismic requirements, strict building codes, and occupied buildings create challenges that are difficult to solve from drawings alone.

AR&B brings more than a century of local construction experience to these conditions, helping project teams identify practical solutions before issues reach the field.
