Construction Purchasing Administrator

Sopris Homes is a leading custom and production home builder, remodeler, and land developer based in Boulder County, Colorado. We pride ourselves on delivering exceptional quality, transparency, and customer service in every project. Our team values collaboration, attention to detail, and a commitment to building both exceptional projects and lasting relationships.

Please note:

We are hiring for this role directly. We do not work with recruiting agencies or third-party staffing firms and will not respond to solicitations of any kind.

The Construction Purchasing Administrator is responsible for running the purchasing and bidding process that keeps Sopris Homes' projects on schedule and within budget. This role owns the flow of work from bid solicitation through issued purchase order, work order, and change order, and maintains the purchasing records that the construction, design, and accounting teams rely on daily.

This is a detail-driven position. The accuracy of the documents this role produces, and the persistence with which it pursues outstanding bids and pricing, directly determine whether the field has what it needs when it needs it. The Construction Purchasing Administrator is a central part of the project team and is expected to foster strong communication with vendors, subcontractors, and the internal team, maintaining Sopris Homes' high standards for detail, quality, and customer satisfaction.

Prior experience in the construction industry is required.

• Set up new vendors and trade partner agreements, maintain up-to-date records, and onboard new partners according to company standards.
• Solicit, collect, and analyze competitive bids from trade partners for all homebuilding and remodeling tasks.
• Track every outstanding bid request and conduct consistent, professional follow-up by email and phone until a bid is received or the trade partner formally declines.
• Draft and review scopes of work to ensure clarity and completeness, avoiding scope gaps or overlaps.
• Review incoming bids for completeness, verifying inclusions, exclusions, quantities, and unit pricing, and identify where a low number reflects excluded scope rather than competitive pricing.
• Prepare bid comparisons that present competing proposals on a consistent, apples-to-apples basis for review.
• Maintain and update vendor and subcontractor contact lists, trade classifications, and qualification documents.

• Prepare, issue, and track work orders, purchase orders, contracts, and change orders.
• Verify scope language, contract amounts, dates, and accounting codes on every document prior to issuance, and confirm that no values have been carried over in error when a document is prepared from an existing template.
• Ensure contracts and contract documents are complete, accurate, and fully executed prior to the start of new projects.
• Manage revisions and superseded documents so the project file always reflects which version is current and what it replaced.
• Maintain detailed and organized purchasing records within company file-sharing platforms (One Drive, Dropbox, Buildertrend, etc.), following established naming conventions exactly.
• Upload and archive all purchasing documents in relevant systems for easy retrieval and audit readiness.

• Maintain and update bid tabs, budgets, bid logs, and project cost information frequently to reflect actual and projected expenses.
• Record each filed bid and quote contemporaneously, including trade, vendor, quote number, amount, and what it supersedes, so project cost information is never reconstructed from memory.
• Reconcile subcontractor and supplier invoices against committed purchase order, work order and change order amounts, and report and reconcile variances before payment.
• Support cost analysis and value engineering efforts to identify cost‑saving opportunities without compromising quality.
• Track and maintain documentation related to product rebates and incentives from manufacturers and suppliers.
• Monitor material pricing and lead times affecting active projects and communicate cost or schedule risk early.
