Job Title: Estimator – Renewable Energy & Decarbonisation
Location: Bristol / Hybrid
Salary: £70,000 - £80,000 (DoE)
Benefits: Healthcare, Pension, Bonus
Position Overview
On behalf of a leading Tier 1 Main Contractor, we are seeking an Estimator to lead the commercial development of high-value renewable energy and decarbonisation tenders.
This role requires a sophisticated understanding of MEP systems, renewable technologies (GSHP/ ASHP, Solar PV, BESS, Heat Networks), and the complex procurement frameworks typical of large-scale infrastructure projects.
The successful candidate will be responsible for ensuring that all tenders are technically robust, commercially competitive, and fully aligned with the client’s carbon-reduction objectives.
Core Duties & Responsibilities
1. 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. Stakeholder Engagement
* Pre-Construction Liaison: Act as the primary commercial point of contact for clients, consultants, and internal departments during the bid phase.
* Handover Management: Ensure a seamless transition of commercial data from the Pre-Construction phase to the Operations and Surveying teams upon successful contract award.
Candidate Requirement
* Sector Experience: Extensive experience in estimating within a Tier 1 or large-scale specialist contractor environment, specifically within the Renewables or M&E sectors.
* Technical Proficiency: Advanced competency in estimating software (e.g., Candy, Conquest, or Causeway) and a deep understanding of BIM/Digital Construction workflows.
* Communication: Exceptional written and verbal communication skills, with the ability to present complex commercial data to senior stakeholders.
