Industrial Mechanical Estimator

This is an excellent opportunity for an experienced estimator with a strong background in mechanical building services to join a successful business delivering technically challenging projects across a range of sectors. The Mechanical Estimator will play an important role within the pre-construction function, taking responsibility for the preparation of accurate, competitive and commercially robust tenders. You will be involved throughout the tender process, from the initial review of enquiries and technical documentation through to final submission, tender clarification and handover to the delivery team following contract award.

The successful candidate will have a comprehensive understanding of mechanical building services and be comfortable estimating packages incorporating HVAC, heating, chilled water, ventilation, air conditioning, domestic water, drainage and public health systems .

The Role As Mechanical Estimator, you will work closely with the wider estimating, commercial, design and operational teams to develop competitive tender submissions that accurately reflect the scope, specification, programme and commercial requirements of each project. You will review tender documentation in detail, undertake accurate take-offs, obtain quotations from the supply chain and build comprehensive cost plans covering labour, materials, plant and subcontract packages.

A key part of the position will be identifying potential commercial and technical risks at tender stage while also recognising opportunities for value engineering, alternative specifications and more efficient methods of delivery. You will be expected to manage your own workload across multiple tender opportunities while ensuring submissions are completed accurately and within the required deadlines.

Key Responsibilities Review incoming tender enquiries and establish the full mechanical scope of works. Analyse drawings, specifications, schedules, bills of quantities and other tender documentation. Prepare detailed and accurate estimates for mechanical building services packages. Undertake mechanical quantity take-offs from drawings and specifications. Produce labour, material, plant and subcontractor costings. Prepare bills of quantities and detailed pricing schedules where required. Issue enquiries to suppliers and subcontractors and obtain competitive quotations.

Review and commercially evaluate supplier and subcontractor returns. Ensure quotations received are technically compliant with the tender requirements. Identify exclusions, qualifications, assumptions and areas requiring clarification. Assess project risks and opportunities during the tender process. Identify potential value-engineering opportunities and alternative technical solutions. Liaise with consultants, clients and the internal design team regarding technical queries. Work closely with commercial and operational teams to establish appropriate preliminaries, programme requirements and delivery strategies.

Attend tender review meetings and contribute to internal adjudication processes. Assist with the preparation of tender presentations, clarifications and post-tender negotiations. Maintain accurate estimating records and supporting documentation. Ensure estimates reflect current market rates for labour, materials, plant and subcontract services. Develop and maintain strong relationships with key suppliers and subcontractors. Support the development and maintenance of an effective mechanical supply chain.

Monitor market conditions and pricing trends that could impact future tenders. Provide detailed tender handovers to the commercial and project delivery teams following successful contract awards. Support the wider pre-construction team with cost planning, budgeting and early-stage project assessments where required.
