Mechanical Estimator (Nuclear & Major Projects)

Up to £70,000 + Car Allowance + Comprehensive Benefits Package

Bridgwater | Bristol

An exciting opportunity has arisen for an experienced Mechanical Estimator to join a major engineering delivery team supporting one of the UK’s largest and most significant nuclear infrastructure programmes.

Working on a flagship project within a highly regulated environment, you’ll play a key role in developing robust, commercially competitive tender submissions for complex mechanical building services packages.

Supporting the Hinkley Point C programme doesn’t necessarily mean being based on site every day. Alongside project activities at HPC, the team also operates from offices in Bridgwater and Bristol, offering a level of flexibility not commonly associated with major nuclear projects.

The Role

You will be responsible for the preparation of detailed cost estimates across a range of complex mechanical building services works, supporting tender submissions from initial enquiry through to final commercial review. Operating within a highly regulated project environment, you’ll produce technically robust estimates, assess delivery risks and opportunities, and contribute to the successful tendering of major mechanical packages.

Key Responsibilities

  • Prepare detailed estimates for mechanical building services packages.
  • Review drawings, specifications and tender documentation.
  • Undertake detailed quantity take-offs and pricing exercises.
  • Obtain and evaluate quotations from suppliers and subcontractors.
  • Identify risks, opportunities and value engineering proposals.
  • Develop tender clarifications, assumptions and exclusions.
  • Support tender review and governance processes.
  • Collaborate with operational and commercial teams to develop winning bids.
  • Maintain accurate estimating and tender records throughout the bid lifecycle.

What We’re Looking For

  • Proven experience as a Mechanical Estimator within Building Services, M&E or MEP contracting, ideally delivering projects within the nuclear, energy, infrastructure or other highly regulated sectors.
  • Strong technical knowledge of HVAC, heating and cooling systems, pipework, public health services and associated mechanical plant.
  • Experience preparing estimates for complex construction, engineering or infrastructure projects.
  • Ability to interpret technical drawings and specifications.
  • Strong commercial awareness and attention to detail.
  • Excellent communication and stakeholder management skills.
  • Experience working within major projects, nuclear, defence, energy, power generation or similarly regulated environments would be highly advantageous.
  • Relevant engineering qualifications are desirable.

Package

  • Salary up to £70,000
  • £5,780 Car Allowance
  • Choice of 9-Day Fortnight or Traditional 5-Day Working Week
  • Access to offices in Bridgwater, Bristol and Hinkley Point C
  • 26 Days Annual Leave
  • Private Healthcare
  • Life Assurance (4x Salary)
  • 5.75% Employer Pension Contribution
  • Travel and Lodge Allowances where applicable
