QA/QC Supervisor - Silver Hill at Unity Homes

Role purpose:

The QA/QC Supervisor owns quality on the Silver Hill Project, from design review through handover. The role ensures every material, process, and finished element meets the approved drawings, specifications, contract requirements, and applicable Kenyan and international standards.

The postholder builds and runs the Project Quality Plan, leads the QA/QC team, and acts as the project’s authority on inspection, testing, non-conformance, and quality records. The goal is zero-defect handover, minimal rework, and full client confidence.

Key Responsibilities:

Quality planning and systems

• Develop, implement, and maintain the Project Quality Plan (PQP) in line with ISO 9001 and the contract’s quality requirements.
• Prepare Inspection and Test Plans (ITPs), method statements, review procedures, checklists, and quality forms for each work package.
• Define hold and review points.
• Keep quality procedures current as the project moves through each phase.

Quality control and inspection

• Plan and supervise daily site inspections, testing, and verification of works against approved drawings and specifications.
• Oversee material approvals, receiving inspections, and sampling of materials such as concrete, steel, aggregates, blocks, and finishes.
• Coordinate with accredited testing laboratories and review test results (e.g., concrete cube strength, compaction, rebar tensile tests).
• Witness critical activities, including foundations, concrete pours, structural steel, waterproofing, and MEP installations and commissioning.
• Approve or reject work and authorize release of hold points.

Non-conformance and corrective action

• Run the Non-Conformance Report (NCR) process: raise, track, investigate root causes, and verify close-out.
• Drive corrective and preventive actions (CAPA) and lessons learned across teams.
• Escalate systemic quality risks to the project manager early, with proposed solutions.

Audits and compliance

• Plan and lead internal quality audits of site teams, subcontractors, and suppliers.
• Host and support third-party audits.
• Ensure compliance with relevant statutory requirements, building codes, and standards (e.g., KEBS, NCA, and county approvals, Eurocodes, or British Standards as specified).

Supplier and subcontractor quality

• Pre-qualify and evaluate suppliers and subcontractors on quality capability.
• Review subcontractor quality plans and ITPs before work starts.
• Monitor subcontractor performance and enforce quality obligations in their contracts.

Documentation and handover

• Maintain complete, traceable quality records: inspection requests, test certificates, material approvals, NCRs, and calibration records.
• Manage snagging and de-snagging, and certify completion of works.
• Compile quality dossiers, as-built records, O&M manuals, and handover documentation.

Leadership and reporting

• Lead, coach, and appraise the QA/QC team; allocate inspection resources across the site.
• Run quality inductions, toolbox talks, and training for site staff and subcontractors.
• Produce weekly and monthly quality reports and present quality performance at project meetings.
• Work alongside the Health, Safety, and Environment (HSE) team to embed a culture of doing it right the first time.

Qualifications and experience:

• At least 10 years in construction or infrastructure, with 5+ years in a senior QA/QC role on large projects.
