Describe the exposure you need
Distinguish a pothole to verify a utility crossing from a trench, foundation exposure or cleanup assignment. Provide the proposed location and dimensions, the purpose of the excavation and available plans. If the final depth is unknown, explain what information you need the contractor to establish rather than presenting a guess as a requirement.
Ask whether the provider offers water excavation, air excavation or both, and why its proposed method fits the work. These terms are sometimes grouped in advertising, but the actual equipment and resulting material-handling arrangements matter. Confirm that the company performs excavation rather than only drain cleaning or pumping waste from existing structures.
Assign utility coordination
Sunshine 811’s process distinguishes its member utility responses from private-facility locating. Before the visit, identify who handles notification, verifies responses and investigates private lines. Give the contractor available records, but let it determine what further verification is needed for its operation. A drawing or paint mark is not a reason to skip the agreed excavation precautions.
Ask who will be present to identify the exposed asset and authorize the next stage. If the purpose is to resolve a conflict for a bore or trench, the surveyor, designer or installing contractor may need a record before the hole is closed. Schedule that handover, not just the vacuum truck.
Check truck positioning and reach
Show the bidder the route from the street to the proposed setup position, including gates, overhead features, soft ground, slopes and restricted areas. Explain whether the truck must remain outside a secure facility or away from a finished driveway. Ask the provider to confirm practical reach and any effect of long hose runs on the work.
For an occupied site, identify traffic movements, delivery windows and emergency access that must remain open. Parking a truck is not the same as providing a suitable work area for its hoses, crew and support equipment. Ask who arranges cones, barriers and any permissions needed to occupy the proposed position.
Understand the charging structure
Request a breakdown of mobilization, crew time, equipment time, travel, water, disposal and any minimum booking. Ask when the clock starts and stops and how off-site disposal trips are charged. Two identical hourly rates can produce different totals if one includes a crew, disposal or travel that the other excludes.
Where the amount of material is uncertain, request an estimate with explicit assumptions and a limit that triggers another approval. For recurring work, ask for daily records showing attendance, tasks completed and disposal trips. The objective is not to eliminate uncertainty but to make it visible enough that you can manage it.
Resolve spoil and water arrangements
Ask where excavated material will be taken, what the price assumes about its condition and what information the contractor needs about possible contamination. Material from a routine utility exposure and material from a potentially contaminated site should not be treated as the same disposal assignment without review. Do not assume it can be discharged into a drain or left on the property.
Clarify water supply, refill trips and site cleanup. Ask whether the contractor supplies everything required or expects an accessible authorized connection. If waste documentation is required by the project, specify the records and responsible party. These arrangements affect both cost and the sequence of the day’s work.
Plan for open holes and the next trade
The excavation may need to remain open for inspection, surveying or installation. State who controls the opening, protects it from public access and decides when it can be backfilled. Ask the contractor to identify what its quote includes for temporary protection and what transfers to the general contractor or property manager.
Backfilling, compaction, pavement replacement and landscaping are not automatically included in vacuum excavation. Define each task and the party responsible for it. If another contractor must arrive immediately after exposure, confirm the schedule and what happens if that crew is delayed. Avoid leaving an open excavation with nobody assigned to its condition.
Record useful findings
For utility verification, request photographs with location references and measurements appropriate to the project. Ask the designer or surveyor what record is needed before the work starts. The operator’s informal description may not be enough for a design decision, especially where several lines cross or the excavation does not reveal the expected asset.
Record unsuccessful exposures as well as successful ones. If the crew reaches an agreed limit without finding the target, the next step might be further locating or a revised investigation rather than continued excavation without approval. Keep the observed conditions separate from assumptions about where a utility continues beyond the opening.
Close out the full assignment
Compare the completed exposures with the original request, including any locations abandoned or changed. Confirm disposal records, cleanup and the status of backfill or temporary protection. Ask the contractor to explain any constraints encountered that another trade needs to know before proceeding.
For an hourly job, review the activity record while the work is still fresh. For a fixed scope, verify that the promised deliverables have been supplied. The useful outcome may be reliable information rather than a large quantity of excavated material. Payment and acceptance should reflect the task you commissioned and the documented limits of what was achieved.
