Wet Services & Fire Engineer: Civil or Mechanical / Junior to Mid-Senior / Full ECSA 6-Stage Delivery

Execustaff South Africa (Pty) Ltd; Gauteng; On-site; ZAR 900,000 - 1,100,000; Full time

Job summary

Execustaff South Africa (Pty) Ltd seeks an experienced engineer to lead wet services and fire engineering design across multiple building projects. Responsibilities include domestic water systems, wastewater, fire protection, sustainability integration, and ensuring design compliance with SANS and related standards.

Collaboration with architects and multi-disciplinary engineering teams is essential for project success.

Responsibilities

• Wet services design: Domestic hot and cold-water reticulation per SANS 10252-1, including hot water generation design and specification.
• Water supply storage and booster pump station design, including pump selection and pressure management.
• Soil and wastewater pump station design.
• Specification of packaged water and wastewater treatment plant requirements in coordination with process engineers.
• Conditional assessments of existing building services on retrofit and refurbishment engagements.
• Fire engineering design: Fire-water reticulation for hydrants and hose reels per SANS 10400-W.
• Sprinkler systems per SANS 10287 / BS EN 12845 / NFPA 13 as applicable.
• Fire pumps and pressure management; sizing and selection.
• Fire-water storage sizing and basis-of design reporting.
• Fire safety strategies and fire signage in accordance with SANS 10400-T and related codes.
• Integration with detection / alarm (SANS 10139), smoke control, and means-of escape design.
• Fire-compliance assessment within Company's water audit product — code compliant fire reserves, reticulation and pump adequacy, assessed and reported within the audit standard.
• Sustainability integration: Sustainable urban drainage systems (SUDS) — attenuation, storage, infiltration devices, softened conveyance.
• Rainwater and greywater harvesting design.
• Recycling and reuse of HVAC condensate, process water, and stormwater.
• Integration of groundwater (from borehole abstraction) into building-side reticulation.
• Documentation across all six ECSA stages: Inception, briefing, basis-of design, options analysis.; Developed and detailed design, drawings, specifications, BoQs, tender documentation, contractor evaluation.; Construction administration, site inspection, commissioning, performance verification, close-out, O&M manuals.
• Cross-disciplinary coordination: Coordinate with architects, civil and structural engineers, mechanical engineers (HVAC), electrical engineers, process engineers (groundwater / treatment), and (implementation).
• Resolve interface issues; produce clear deliverables for adjacent disciplines.
• Productisation & methodology: Codify your design work into reusable templates and design tools.
• Contribute to aQco's wet services and fire engineering design standards — including the fire-assessment methodology within our audit product.
