Tender Preparation & Technical Submission Support

• Prepare complete tender submissions including pricing schedules, clarifications, assumptions, risks, and exclusions.
• Support the drafting of technical narratives for tenders across all sectors:
• Residential networks (LV/HV backbone, substations)
• Renewables (33kV solar/BESS/wind connections)
• Industrial & Commercial new connections
• High-power eMobility and fleet depots
• Ensure each tender reflects compliant DNO/IDNO G81 design principles, correct construction methodology, and realistic programme durations.
• Lead tender review meetings with the Estimating Lead, ensuring all risks, opportunities, and commercial sensitivities are understood.
• Participate in tender Q&A processes, coordinating with design and engineering teams for technical responses.

Supplier, OEM & Subcontractor Engagement

• Source and evaluate quotations from HV/LV civil contractors, cable installers, jointers, switchgear and transformer OEMs, metering providers, and specialist subcontractors.
• Ensure all subcontractor and OEM returns align with the specific DNO/IDNO standard specifications issued for each tender.
• Maintain accurate cost libraries and regularly benchmark pricing to ensure competitiveness.
• Build strong working relationships across the supply chain to support pricing accuracy and programme feasibility.

Technical & Regulatory Compliance

• Ensure all costings align to G81 standards, relevant DNO/IDNO engineering specifications, and NERS-accredited methodologies.
• Understand and correctly price contestable vs non‑contestable scope in line with DNO rules.
• Interpret circuit diagrams, protection layouts, substation drawings, cable routing, ducting, and earthing requirements.
• Incorporate CDM implications into estimating (temporary works, HV safety, access constraints, PPE, permits, etc.).
• Validate design inputs to ensure estimates reflect correct cable ratings, load assessments, plant specifications, and site conditions.

Commercial Governance & Tender Handover

• Identify commercial and delivery risks early, highlighting items requiring client clarification or design verification.
• Prepare internal tender handover packs, ensuring operations have a clear understanding of scope, assumptions, and constraints.
• Support post‑tender review and negotiation with clients where required.
• Track tender performance metrics (win/loss analysis, cost accuracy, margin performance) and support continuous improvement.
• Ensure strict adherence to internal governance for tender approval thresholds and sign‑off processes.

Stakeholder Collaboration

• Work collaboratively with design engineers, operations teams, procurement, HSQE, and the commercial function.
• Participate in site visits with project managers, clients, DNOs/IDNOs, and subcontractors to validate estimating assumptions.
• Support client engagement meetings to present tender breakdowns, technical clarifications, or VE proposals.
• Communicate effectively with external stakeholders including IDNOs, DNO technical teams, clients, OEMs, and suppliers throughout the tender lifecycle.
