Company Overview

Our client is a well-established civil engineering and groundworks contractor with a turnover of approximately £45 million per annum. The company operates within the groundworks, reinforced concrete (RC) frame, external works, and Section 278 (highway) works sectors.

They are known for delivering high-quality projects across London and the South East, with a sweet spot project size between £6–8 million, and regular smaller packages in the £3–4 million range. On average, the estimating team handles around £10 million of tenders per month.

The business prides itself on maintaining a collaborative, hands-on working environment where knowledge-sharing, mentoring, and teamwork are central to success.


The Estimating Team

The existing estimating department comprises:

  • 2 Senior Estimators with extensive industry experience.
  • 1 Intermediate Estimator (mid-level).
  • 1 Estimating Assistant.

Following recent internal movement, the team is now seeking a new Estimator to work closely with the two Senior Estimators — either a Junior eager to develop their career or a Mid-Level Estimator ready to take on more responsibility.


The Role

The successful candidate will play a key part in preparing accurate and competitive tenders for a range of civil engineering and structural projects. Working under the guidance of Senior Estimators, you will assist in developing cost plans, analysing tender documentation, and ensuring high-quality bid submissions.

This role is ideal for someone who enjoys working within a supportive, team-oriented office, where mentorship and professional development are actively encouraged.

  2. Collaboration & Review
    • Work alongside Senior Estimators to verify quantities, rates, and overall cost accuracy.
    • Participate in tender adjudication meetings and risk assessments with the senior team.
    • Coordinate with engineers, suppliers, and subcontractors to gather competitive quotations.
  3. Technical & Commercial Inputs
    • Build rates using estimating software, incorporating up-to-date material, labour, and plant rates.
    • Ensure all project documentation (BOQs, quotes, programmes) is filed correctly within internal estimating systems.
    • Support senior management in the smooth transition of projects from estimation to delivery.
  4. General Duties
    • Conduct site visits when required to assess conditions or verify information.
    • Contribute to continuous improvement of estimating processes and databases.
    • Treat all tender information as confidential and ensure all bids are submitted exclusively for the company.

Essential:

  • Minimum 1 year of experience in estimating within groundworks, RC frame, or civil engineering sectors (up to 4 years for the mid-level role).
  • Strong technical understanding of construction processes and sequencing.
  • Proficient in Excel and estimating software packages.
  • Excellent numeracy, attention to detail, and organisational skills.
  • Confident communicator with strong interpersonal skills and the ability to work collaboratively.
