Define the product and route
Provide a route plan showing the start and end points, approximate length, proposed pipe or conduit, crossings and access constraints. State whether the work is a new installation, a replacement or part of a larger utility project. Ask the responsible designer or utility owner to confirm the product requirements and acceptable route before contractors price construction.
A route drawn for estimating is not necessarily ready for drilling. Ask who supplies the approved profile, installation tolerances and any survey control needed by the project. Record whether design, surveying and as-built documentation belong to the drilling contractor or to another party so the price reflects the actual assignment.
Plan utility investigation before equipment arrives
OSHA’s directional-drilling bulletin emphasizes locating existing utilities and verifying their positions because the bore is not directly visible. Ask how the contractor will combine available records, the state notification process, private locating and physical exposure where needed. A collection of utility drawings is not a complete site verification plan.
Sunshine 811 explains that its member companies do not locate private facilities. Identify private lines on the property and assign responsibility for investigating them. Have the contractor describe how unresolved conflicts, inaccessible crossings or inconsistent marks affect the schedule. Do not treat a booked drilling date as permission to proceed past an unresolved utility question.
Ask what is known about ground conditions
Share geotechnical information and prior excavation records that are available, while clearly identifying their location and age. Ask the bidder which assumptions it is making about the route and how those assumptions affect equipment, tooling and production. Conditions at a nearby project are not proof of conditions throughout this bore.
Request the change procedure for obstructions, unexpected ground or inability to maintain the planned route. A useful proposal distinguishes investigation costs, a revised method and an abandoned attempt. Ask who decides whether to continue, redesign or stop, and what records support a request for additional payment.
Include the entire construction footprint
The drilled section is only part of the work area. Have the contractor identify rig setup, product staging, entry and exit areas, access pits where proposed, support vehicles and the working corridor. Check whether the required space conflicts with deliveries, parking, landscaping, neighboring property or public access.
For roadway, waterway or other controlled crossings, assign responsibility for permissions and coordination with the asset owner. Ask who handles traffic arrangements and reinstatement obligations. Do not assume a trenchless method eliminates surface disturbance or permits. The proposal should describe the footprint it expects to use and the process for approving any expansion.
Discuss drilling-fluid and environmental controls
Ask the bidder to explain its proposed fluid-management and cleanup plan in terms appropriate to the site. Identify who supplies water, contains and removes material, responds to an unexpected surface return and authorizes continuation after a problem. Keep this discussion tied to the route and applicable project requirements rather than accepting a generic assurance that the process is clean.
Where the work approaches sensitive water, drainage or property features, request the responsible designer’s or authority’s conditions before construction pricing is finalized. The contractor should identify the records and notifications it will provide if the planned operation cannot continue as expected. Owners need a decision process, not instructions for operating the drilling equipment.
Compare the installed scope, not just bore footage
Have bids distinguish mobilization, drilling, product supply, fusion or assembly, installation, locating, excavation, testing and restoration. Ask whether pulling a conduit includes installing cable or making a utility connection; often those are separate tasks that must be assigned. Define treatment of unsuccessful or redrilled sections before work starts.
For a lump sum, request the stated assumptions and exclusions. For measured work, agree how length and quantities are determined and who records them. Compare waiting-time charges, additional mobilizations and owner-caused delays. A lower drilling rate can be outweighed by omitted tasks or assumptions that another bidder has already included.
Specify the completion evidence
Ask the asset owner or designer what acceptance records are required for the installed product. These may concern route, depth, testing, continuity, connection work or restoration, depending on the project. Put the actual requirements in the contract rather than relying on a general promise of an as-built.
Agree the format and reference system for the final record. A hand sketch without clear endpoints may be insufficient for future maintenance, while an elaborate survey may be unnecessary for a small defined scope. What matters is that the record serves the owner’s intended use and that its accuracy and limitations are explained.
Coordinate handover to the next contractor
Name the party accepting the installed pipe or conduit and the party completing connections, service commissioning or subsequent excavation. Ask when the bore contractor’s responsibility ends and what protection is needed before the next trade takes over. A completed pull is not the same as an operating utility.
Walk the affected surface areas and compare restoration with the agreed condition. Collect approved changes, installation records and outstanding items before closing the job. For work across several properties or managed assets, identify who signs off each area. A clear handover reduces disputes when a later task reveals a limitation that was already documented during drilling.
