Operating for over 45 years, King & Moffatt Building Services provide complete Mechanical and Electrical services across all sectors of the construction industry including Industrial, Logistics, Food, Pharmaceutical, Data Centre, Mining, Healthcare, Commercial, Hotel & Leisure, High-End Residential, Public, and Energy.

From design stage to the installation and the ongoing maintenance of their facilities, our valued and highly skilled workforce provide our clients with an efficient, reliable and best in class service.

A Deloitte Best Managed Company Award winner for eight years running, we pride ourselves on being a full building services solutions provider and have successfully delivered multiple large-scale projects in Ireland, the UK & mainland Europe.

• Tender Analysis: Lead the initial review of tender packages, identifying and developing a "Query List" to clarify ambiguities in the mechanical specification. 

• Digital Take-off: Manage and coordinate the measurement of mechanical services (Ductwork, Pipework, Insulation) from 2D PDFs or 3D Revit models. 

• Costing & Pricing: Lead the application of labour norms and material discounts to the "Bill of Quantities," ensuring all ancillaries (valves, brackets, fixings) are included. 

• Subcontractor Enquiries: Identify and manage the distribution of enquiries to specialist trades, such as BMS, Insulation, and Water Treatment, reviewing and critiquing their returns. 

• Plant Selection: Review and critique mechanical plant schedules to ensure specified equipment is "fit for purpose" and identify potential "Value Engineering" alternatives. 

• Site Inspections: Manage and coordinate "Site Walk-arounds" for refurbishment projects to identify existing services and potential installation constraints. 

• Tender Settlement: Provide regular internal updates to the Managing Estimator regarding the "Prime Cost" and potential commercial risks. 

• Handover Documentation: Lead the preparation of the "Tender Handover File" for the Project Team, clearly documenting all "Assumptions and Exclusions." 

• Market Monitoring: Review and critique material price trends (e.g., copper, steel, plastic) to ensure the estimate reflects current market volatility. 

• Stakeholder Engagement: Arrange and chair (where necessary) mid-tender interviews with clients to present the mechanical proposal and technical approach. 

• Lessons Learned: Capture and document feedback from "Post-Project Reviews" to refine labour norms and pricing accuracy for future bids. 

• This list is not exhaustive or exclusive. 

• Experience: 3–7 years’ experience in mechanical estimating within the building services or construction sector. 

• Education: HNC/HND in Mechanical Engineering or Building Services. A background as a time-served Plumber or Pipefitter is highly advantageous. 

• Technical Knowledge: Strong understanding of HVAC systems, BESA ductwork standards (DW/144), and pipework specifications (TR/20). 

• Software Literacy: Proficiency in Trimble Luckins, Ensign, or Cymap. Expert knowledge of Bluebeam Revu for digital measurements is essential. 

• Communication: Exceptional interpersonal skills; able to negotiate with suppliers and explain technical pricing to the commercial team. 

• Attention to Detail: A methodical approach to ensuring no "scope gaps" exist between the mechanical and electrical or civil interfaces.
