Preconstruction Manager – Commercial & Industrial Construction

Irmo, SC (Columbia area) | Full-time


We’re a commercial general contractor with offices in Greenville, Charleston and Irmo. We’re hiring a Preconstruction Manager for our Irmo office.


In this role you’ll set projects up to succeed before anyone breaks ground. You’ll lead estimates from early concept through to final pricing, spot risk early, and hand operations a job they can actually build.


What you’ll do

  • Run several estimates at once, at every stage from conceptual through schematic, DD, GMP, lump sum and hard bid
  • Set the estimate strategy and keep scope and budget aligned from one phase to the next, explaining to clients what changed and why
  • Review drawings, specs and contract documents for gaps, and flag scope and procurement risk early
  • Do detailed quantity takeoffs and check subcontractor and supplier pricing against what you know of the market
  • Get good trade coverage on every bid and find the right trade partners for each job
  • Plan procurement for long-lead materials and equipment
  • Help with schedules, phasing plans and constructability reviews
  • Lead value engineering when a project needs to hit the owner’s budget
  • Write clear estimate clarifications that can stand up as a contract exhibit
  • Keep historical cost data up to date so the next estimate is sharper
  • Attend pre-bid meetings and site walks, and hand off each project cleanly to the operations team
  • Take part in interviews and presentations, and build relationships with owners, architects, engineers, subs and suppliers
  • Mentor estimators and help improve how the department works, including processes and technology


What we’re looking for

  • 3 years as an Estimator or in a similar role, with experience leading estimates and managing preconstruction
  • Commercial or industrial estimating experience
  • Field experience is a big plus
  • A degree in Construction Management, Engineering, Architecture or a related field is preferred
  • Destini Estimating or similar estimating and takeoff software
  • Bluebeam and strong Excel skills
  • Working knowledge of Microsoft Project or Primavera P6
  • A good understanding of building systems, cost drivers, code requirements and LEED
  • You’re organized, you move quickly, and you can handle several deadlines without the quality slipping
  • You’re confident presenting to clients and good at building relationships


What we offer

  • Competitive base salary based on experience
  • Performance-based bonus
  • Medical, dental and vision insurance
  • 401(k) with company match
  • Paid time off and company holidays
  • Support for professional development and continuing education
  • Employee wellness program


Other details

This is mainly an office-based role. You’ll get out for site visits, pre-bid walks and client meetings, and you’ll travel regionally between our three offices. There’s some occasional overnight travel for interviews and industry events.
