Mechanical Design and Estimation Engineer

SUMMARY:
Mechanical Design and Estimation Engineer

POSITION INFO:

Role Purpose

We are seeking a Mechanical Design & Estimation Engineer to join our Estimation Department. The role includes

developing detailed designs and preparing accurate cost estimates for mechanical systems in MEP/EPC projects,

such as HVAC, plumbing, fire protection, and other related mechanical systems. The ideal candidate will combine

strong technical expertise in mechanical engineering with the ability to deliver competitive, compliant, and cost-

effective tender submissions.

The successful candidate will ensure that all mechanical designs and estimates are accurate, aligned with South

African and international codes and standards, and delivered within deadlines to support both bidding success and

project execution.

2. KEY ACCOUNTABILITIES

 Read carefully the project's specifications, identify relevant codes and standards (e.g., SANS, ASHRAE,

ISO, NFPA…) to have a clear understanding of the design inputs and ensure conformity to

requirements.

 Plan and prioritize own work so as to deliver the expected outputs on time, in accordance with

supervisor's guidance.

 Perform load calculations, equipment sizing, and detailed design for HVAC, plumbing, fire protection,

and other related mechanical systems.

 Perform design modelling, prepare accurate calculation notes, and develop detailed designs according

to the related design manual and predefined design concepts, ensuring error-free, timely, and well-

presented deliverables.

 Ensure designs are coordinated with other disciplines (electrical, civil, structural) to eliminate clashes.

 Prepare and update materials take-offs, ensuring design quantities and specifications remain within the

allocated project budget.

 Prepare and review technical drawings, schematics, and as-built documentation; develop as-built

drawings for executed works; and prepare Operation & Maintenance (O&M) manuals while supporting

project teams with technical inputs during execution.

 Communicate professionally through internal correspondence, reports, and meetings, coordinating with

relevant departments to provide technical support or receive direction.

 Conduct internal presentations on technical subjects to enhance presentation skills, prepare for external

presentations, and share knowledge with colleagues.

 Support other departments and guide CAD operators to ensure delivery of high-quality outputs.

 Perform QA/QC activities on own and peers' designs to detect, analyze, and eliminate discrepancies,

while positively accepting feedback and applying lessons learned to continuously improve skills and

prevent recurring mistakes.

 Review tender documents to gain a clear understanding of project type and scope, and discuss relevant

requirements and specifications with the estimation team to ensure conformity during the estimation

process.

 Prepare preliminary designs or pre-dimensioning for bids on time, ensuring compliance with tender

requirements.

 Prepare detailed BOQs to confirm project quantities for pricing.

 Request and evaluate supplier quotations in conjunction with the procurement department, analyze for

compliance, and recommend suitable options.

 Collaborate with relevant departments to compile the complete project offer, ensuring that all technical,

financial, and commercial aspects are accurately integrated, reviewed, and aligned with the tender

requirements and the company's standards before submission.

3. PERFORMANCE INDICATORS

 Ability to identify and apply relevant design codes and standards, including South African (SANS) and

international requirements, ensuring all designs conform to standards, manuals, requirements, and best

engineering practices.

 Quality of work planning/organization.

 Timely execution of assigned tasks.

 Deliver error-free designs, accurate calculation notes, and detailed priced BOQs, ensuring all outputs

are submitted on time.

 Quality of quotations requested, analyzed, and compared for conformity to project specifications.

 Quality and timeliness of inputs provided for the estimation scope, ensuring accurate project costing.

 Participation in compiling the final project offer, ensuring all estimation and technical aspects are

accurate and aligned with tender requirements.

 Contribution to winning competitive tenders through accurate and professional estimation work.

4. QUALIFICATIONS, EXPERIENCE AND SKILLS

 B. Engineering Mechanical degree or equivalent.

 Registration with ECSA as Pr. Eng.

 5 years' experience in design/estimation.

 Strong understanding of engineering standards, including South African (SANS) and relevant

international codes such as ASHRAE, NFPA, and
