Plumbing systems are essential to health, safety, sanitation, water quality, building reliability, equipment support, and occupant experience.

ASI supports plumbing systems across the full project lifecycle — from early planning and design support through BIM/VDC coordination, preconstruction, procurement, installation, testing, startup, commissioning, turnover, and lifecycle operations.

Our approach looks at plumbing as a complete building system architecture: utility service, water treatment, domestic cold water, domestic hot water, hot water return, sanitary waste, vent piping, storm drainage, gas distribution, medical gas, process piping, specialty waste, fixtures, equipment connections, controls, monitoring, and long-term maintainability.

Plumbing systems are coordinated with applicable adopted codes, project specifications, owner standards, manufacturer requirements, authority having jurisdiction requirements, and licensed design professional direction. Common industry references may include the International Plumbing Code, Uniform Plumbing Code, ASPE design guidance, ASHRAE water management guidance, NFPA 99 for healthcare-related medical gas and vacuum systems, and ASSE/IAPMO professional qualification standards where applicable. The IPC establishes minimum plumbing regulations, the UPC is developed through IAPMO’s ANSI-accredited consensus process, and ASPE identifies its Plumbing Engineering Design Handbook as a core reference for plumbing engineering design practices. 

ASI supports planning, coordination, delivery, and commissioning for a broad range of plumbing systems, including:

Utility water service, meters, backflow prevention, pressure regulation, booster pumps, domestic cold water, domestic hot water, hot water return, mixing valves, water treatment, filtration, softening, point-of-use treatment, and water quality monitoring.

ASI applies a sequential workflow to plumbing systems so that performance, code alignment, constructability, installation, testing, commissioning, and operations are connected early.

Define owner goals, facility type, water demand, drainage requirements, utility points of connection, equipment needs, water quality requirements, pressure zones, temperature requirements, gas demand, specialty systems, budget, schedule, risk, maintainability, and operational expectations.

Review system concepts, design intent, fixture counts, equipment loads, pipe routing, riser strategy, water heating strategy, recirculation approach, drainage layout, venting strategy, gas distribution, backflow requirements, water treatment, specialty systems, access, serviceability, and constructability.

When sealed design documents are required, ASI coordinates with licensed design professionals and strategic engineering partners.

Coordinate plumbing mains, risers, branches, sleeves, penetrations, equipment rooms, fixture carriers, access zones, cleanout locations, drain elevations, roof drain routing, medical gas routing, gas piping, supports, prefabrication opportunities, and clash detection with mechanical, electrical, structural, architectural, fire/life safety, and technology systems.

Develop budgets, estimates, procurement strategies, long-lead equipment plans, phasing, logistics, value analysis, constructability reviews, schedule sequencing, manpower planning, and risk registers.

Coordinate plumbing fixtures, water heaters, boilers, tanks, pumps, interceptors, valves, water treatment equipment, backflow preventers, medical gas components, specialty piping materials, submittals, vendor data, lead times, warranty requirements, startup requirements, and owner standards.

Support or perform installation of piping, fixtures, equipment, hangers, supports, valves, cleanouts, drains, insulation, pumps, tanks, accessories, controls devices, instrumentation, and specialty systems with attention to safety, quality, access, code requirements, and maintainability.

Support pressure testing, leak testing, flow verification, slope verification, fixture testing, backflow testing, flushing, disinfection, water quality verification, gas testing, medical gas verification where applicable, and documentation of test results.

Verify equipment readiness, pump rotation, water heater startup, temperature controls, recirculation performance, booster system operation, alarms, valves, safeties, instrumentation, controls points, and integration with BAS or monitoring platforms where applicable.

Support functional testing, sequence verification, water temperature verification, domestic hot water return performance, pump control verification, alarm testing, leak detection testing, medical gas interface verification where applicable, deficiency tracking, documentation, owner training, and turnover.

Support O&M documentation, preventive maintenance planning, asset data, fixture schedules, valve charts, water management plans, flushing procedures, seasonal review, optimization, modernization planning, and lifecycle improvement. ASHRAE Standard 188 addresses legionellosis risk management for building water systems, including water management program principles, design considerations, documentation, balancing, a

ASI evaluates plumbing systems through the lens of long-term performance, safety, reliability, and maintainability.

Key priorities include:

• Public health and sanitation 
• Water quality 
• Safe potable water delivery 
• Reliable hot water performance 
• Pressure stability 
• Drainage performance 
• Venting performance 
• Backflow protection 
• Water efficiency 
• Leak detection 
• Maintainability and access 
• Fixture performance 
• Equipment reliability 
• Gas system safety 
• Medical gas reliability where applicable 
• Testing and verification readiness 
• Documentation quality 
• Lifecycle cost 
• Operational efficiency

Plumbing systems should be planned, coordinated, installed, tested, verified, commissioned, and operated in alignment with applicable adopted codes, project requirements, owner standards, manufacturer instructions, authority having jurisdiction requirements, and licensed design professional direction.

Relevant industry references may include IPC, UPC, ASPE design references, ASSE standards, ASHRAE water management guidance, NFPA 99 for healthcare facilities, project specifications, and manufacturer installation requirements. Final requirements depend on the project scope, jurisdiction, adopted code cycle, facility type, contract documents, and design professional direction.

ASI’s role is to help align the field, design intent, coordination process, installation requirements, testing plan, commissioning expectations, and operations needs so that plumbing systems are delivered safely, efficiently, and with confidence.

Plumbing systems succeed when planning, design support, coordination, installation, testing, commissioning, and operations are connected early. ASI helps bridge those gaps through practical field experience, BIM/VDC workflows, preconstruction planning, disciplined installation, verification, commissioning readiness, and lifecycle support.

The result: plumbing systems that are coordinated, code-aligned, maintainable, reliable, and ready to perform.
