Job Description

Plumbing and fire protection engineer

Education

Education: B.E. / B.Tech in Mechanical Engineering or equivalent (mandatory). ASPE affiliation, NICET awareness, or fire protection coursework is a plus

Job description

own the wet-side scope of US building projects — domestic water, sanitary and storm drainage, natural gas, and fire suppression systems — from sizing calculations through coordinated construction documents and construction administration. Plumbing design is executed in full; fire protection work centres on system design criteria, sprinkler layouts, and performance specifications, coordinated with the fire protection contractor’s detailed shop drawings and hydraulic calculations

Plumbing Design & Engineering

• Design domestic cold and hot water systems using fixture-unit methodology — pipe sizing, booster pumps, water heater selection, mixing and recirculation provisions
• Design sanitary waste and vent, storm drainage (including overflow provisions), and natural gas piping systems per the applicable plumbing and fuel gas codes.
• Size and specify interceptors, backflow prevention, and water treatment provisions as required by the project and jurisdiction.
• Select and schedule plumbing fixtures and equipment; verify water-efficiency requirements (EPAct, state codes, CALGreen / LEED where applicable).

Fire Protection Design

• Develop fire suppression design criteria — hazard classification, density / area requirements, and water supply analysis — per NFPA 13.
• Prepare sprinkler system layouts, standpipe designs (NFPA 14), and fire pump arrangements (NFPA 20), including underground fire service mains (NFPA 24).
• Understand hydraulic calculation principles and review the fire protection contractor’s shop drawings and calculations against the design intent.
• Coordinate fire protection systems with architecture, structure, and the other MEP disciplines — ceiling coordination, pipe routing, and equipment access.

Construction Documents & BIM

• Produce complete, code-compliant construction document sets in Revit to office standards across SD, DD, CD, and CA phases.
• Coordinate with mechanical and electrical disciplines; resolve clashes and integration issues before drawings are issued, using Navisworks and BIM coordination sessions.
• Draft project-specific specification sections for plumbing and fire suppression systems (MasterFormat Divisions 21 / 22).

Construction Administration

• Own the RFI workflow on your projects — receive, interpret, respond, log, and track to closure, with responses that need minimal revision from the US team.
• Prepare plan check / AHJ comment responses and resolution drawings for US jurisdiction submissions.
• Review vendor submittals and fire protection shop drawings, evaluate substitution requests, and coordinate with vendors and manufacturers’ representatives.
• Assist with change order documentation, participate in punch list development, and review designs for constructability before issue

US/ Client interface

Tool Expected proficiency

Revit (MEP) Mid: advanced — models plumbing and fire protection systems from scratch, coordinated sheets, schedules. Senior: expert — sets model standards, resolves model health issues, reviews others’ work.

AutoCAD Proficient to expert — fast, accurate 2D production to office standards.

Sizing & calc tools Proficient — fixture-unit, storm, and gas sizing via team calculation templates; able to build a structured calculation sheet from scratch.

Hydraulic calc tools Awareness of sprinkler hydraulic calculation software outputs; Senior: reviews contractor calculations at a technical level.

Navisworks Familiar — clash detection and BIM coordination sessions. Senior: leads India-side coordination.

Excel / Bluebeam Strong — calculation workbooks, drawing markups and review sets

Plumbing codes IPC / UPC — sizing, venting, materials, and water supply protection — as the model-code foundation, plus awareness of how states amend them.

Fuel gas IFGC / NFPA 54 — gas pipe sizing and appliance connection requirements.

Fire protection NFPA 13 (sprinklers), 14 (standpipes), 20 (fire pumps), 24 (fire service mains) — design-criteria command; IBC / IFC interface for system requirements.

Primary markets

(added advantage)

California — CPC (Title 24 Part 5) and California Fire Code; Florida — Florida Building Code (Plumbing) and the Florida Fire Prevention Code (NFPA-based); Georgia — state amendments to IPC; New York — NYC Plumbing Code and NYC Fire Code / FDNY requirements. Experience in any of these regimes is an added advantage, not a prerequisite.

Water efficiency EPAct fixture requirements; CALGreen / LEED water credits where applicable.

Specifications Divisions 21 / 22 (MasterFormat) — drafts project-specific sections; Senior authors and approves the full package.
