They possess a unique drive, underpinned by the desire to help improve Africa’s urban development. **ROLE SUMMARY.** The MEP (MECH)  Design Engineer will be a hands-on design professional responsible for the full design lifecycle of mechanical and plumbing systems; from concept design and load calculations through to detailed design, drafting, and the production of construction-ready drawings, specifications, and Bills of Quantities. This is fundamentally a design role. The successful candidate will personally draft drawings, build and develop Revit models, run sizing of mechanical and plumbing system, produce schematics and single-line diagrams, and prepare technical specifications. The role also includes design coordination with architects and structural engineers, design review against codes and standards, and periodic site visits to verify that installations match the issued design intent.  **KEY RESPONSIBILITY** **1)     Mechanical Systems Design** - Produce mechanical design calculations including HVAC heating/cooling load estimation, psychrometric analysis, duct and pipe sizing, pump head computations, and ventilation rate calculations for residential, commercial, and institutional buildings. - Design and draft HVAC layouts (chilled water, VRF/VRV, split and packaged systems), ductwork routes, plant room arrangements, equipment schedules, and mechanical schematics. - Design fire protection systems including wet and dry sprinkler networks, hydrant systems, gaseous suppression for critical rooms, and fire alarm coordination in line with NFPA 13, NFPA 14, NFPA 20, and NFPA 72. - Select equipment, prepare equipment schedules and technical data sheets, and ensure that designs comply with ASHRAE, SMACNA, CIBSE, and the Nigerian Building Code. **2)     Plumbing Design** - Design domestic cold and hot water systems, including booster pump sizing, hot water generation strategy (calorifiers, heat pumps, solar thermal), and water treatment provisions. - Design sanitary drainage, soil and waste stacks, vent systems, grease interceptors, oil separators, and stormwater drainage in compliance with UPC, IPC, and BS EN 12056. - Carry out water demand calculations, fixture unit loads, pipe sizing, and pressure zoning across multi-storey developments. - Design connections to Alaro City’s central utility infrastructure, including potable water, irrigation, sewage, and reclaimed water networks. **3)     Drafting & Production of Drawings** - Personally draft and produce all MEP design drawings; layouts, sections, schematics, single-line diagrams, riser diagrams, equipment schedules, details, and legends; to construction-ready standard. - Build, develop, and maintain Revit MEP models (Mechanical and Plumbing) at the appropriate LOD for each design stage. - Set up sheet sets, title blocks, view templates, annotation standards, and drawing numbering systems aligned with the project’s documentation standards. - Issue drawings at each design stage (concept, schematic, detailed, IFC) with full revision control, transmittals, and supporting drawing registers. - Produce AutoCAD drawings where required for legacy projects, contractor coordination, or 2D-only deliverables. **4)     BIM Coordination & Clash Detection** - Participate in federated model coordination in Revit and Navisworks across architecture, structure, and MEP disciplines. - Run clash detection cycles on the MEP model, resolve hard and soft clashes within the design model, and re-issue updated coordinated drawings. - Maintain Revit templates, families, shared parameters, and view templates for the MEP discipline; develop the library as required for new projects. - Ensure model deliverables meet the agreed BIM standards (ISO 19650 where applicable). **5)    Design Review & Technical Documentation** - Review and check own design output and the design output of junior staff or external sub-consultants for technical accuracy, code compliance, and constructability. - Prepare technical specifications, design basis reports, design narratives, and calculation packages for each project. - Develop and review Bills of Quantities (BOQ) and take-offs from the MEP design, ensuring quantities reconcile with the issued drawings. - Maintain a structured document control system covering drawings, calculations, specifications, and revision history. **6)    Preconstruction Planning** - Provide MEP design input to project programming, packaging strategies, and procurement planning during preconstruction. - Prepare tender documentation including drawings, specifications, BOQs, and technical scopes of work for MEP packages. - Evaluate contractor and subcontractor technical submissions, prequalification responses, and method statements from a design perspective. - Support procurement on long-lead MEP equipment specifications, vendor technical evaluations, and equipment approval processes. **7)   Construction Support & Periodic Site Visits** - Conduct periodic site visits to verify that installations match the issued design intent and to resolve design-related queries that arise during construction. - Review contractor shop drawings, builder’s work drawings, and combined services drawings (CSDs) against the issued design. - Review MEP material submittals, manufacturer data sheets, mock-ups, and product samples against approved specifications. - Respond to Requests for Information (RFIs), issue design clarifications, site instructions, and design change notices as required. - Witness key MEP commissioning activities (pressure tests, insulation resistance tests, balancing) and review commissioning records from a design conformance perspective **8)   Codes, Standards & Compliance** - Ensure all MEP designs comply with applicable codes including NFPA, ASHRAE, CIBSE, IEC, IEEE, BS, EN, UPC, IPC, and the Nigerian Building Code. - Stay current with code revisions, energy efficiency requirements, and sustainability frameworks (LEED, EDGE, BREEAM) ## Requirements **TECHNICAL SKILLS** - **BIM & Modelling:** Hands-on proficiency in Revit MEP (Electrical, Mechanical, Plumbing); must be able to model, annotate, schedule, and produce sheets independently. Navisworks Manage for clash detection.
