How to choose
Start with the work you expect to send out. A small firm handling a few site assessments may need a responsive local driller with a compact crew. A larger firm with overlapping projects may need several rigs, dependable scheduling, and a clear backup plan when equipment is down. Ask how the vendor assigns crews and who handles schedule changes.
Check the contract before comparing proposals. It should spell out mobilization, drilling methods, sample handling, daily logs, delays, site access, and responsibility for utility clearance. Confirm how extra work is approved and documented. Agree on deliverable formats and when field records, boring logs, and lab results are due.
Consider how the vendor's records fit your current workflow. Ask whether logs and coordinates can be delivered in the formats your engineers already use, and whether field data can be reviewed without buying new software. A workable file handoff matters. So does a named contact when data is incomplete or needs correction.
Account for staff time. Find out what training your project managers and engineers need to request work, review logs, and track samples. Ask for a sample report and a brief walkthrough before committing. Request references from firms with similar project types, staffing, and service areas. Speak with the people who schedule work and review deliverables, not only the owner.
Where state or local rules apply, verify that the vendor and its personnel hold the required approvals for the planned work. Confirm who is responsible for permits, notifications, and site-specific requirements. Put those responsibilities in writing.
