Core Duties & Responsibilities1. Tender Management & Estimation Analytical Estimating: Produce detailed, first-principle estimates for complex renewable energy projects, ranging from £3m to £10m. Systems Integration: Coordinate with internal Design and Engineering teams to ensure that renewable technology specifications (e.g., GSHP/ ASHP, Solar, District Heating) are accurately costed and buildable. Benchmarking: Utilise historical data and market intelligence to provide accurate cost-planning and benchmarking for emerging green technologies. 2. Commercial Strategy & Risk Mitigation Risk Profiling: Identify and quantify technical, commercial, and environmental risks inherent in decarbonisation projects, developing comprehensive risk registers for board-level review. Value Engineering: Lead value engineering workshops to identify cost-saving opportunities and carbon-reduction alternatives without compromising project integrity or Tier 1 standards. Contractual Analysis: Review and interpret complex contract documents (primarily NEC4 and JCT) to identify commercial obligations and potential liabilities. 3. Procurement & Supply Chain Governance Supply Chain Selection: Manage the enquiry process with a specialist supply chain, ensuring that all sub-contractor quotations are technically compliant and commercially appraised. Market Analysis: Monitor global supply chain fluctuations (specifically in relation to battery components and PV modules) to mitigate price volatility during the tender period. 4.
