Planning & documentation
Coordinating Existing Utilities at Steel Building Sites
Collect existing utility records, field verification needs, conflict locations, and responsible coordination before steel building excavation or access work.
Define the condition and its scope
Utility coordination includes buried services and overhead conflicts along construction routes.
The site package controls more than the outline of a steel building. Existing grades, drainage paths, utilities, access, soil conditions, and neighboring uses influence what the structural and enclosure teams can detail. Field conditions should be tied to a dated survey or investigation with its stated limits. Describe what is known, what is inferred, and what still needs testing. Give civil, geotechnical, structural, and construction participants the same property and building coordinates before they develop work that cannot easily be moved later.

Gather the inputs before deciding
Collect utility-owner information, available record drawings, prior modifications, and the proposed excavation and delivery routes. Identify approximate locations, missing records, and overhead crossings. Determine applicable locating, verification, and coordination procedures with responsible parties. Keep verified observations distinct from historical documents. Existing records may be useful without being precise enough to authorize excavation or movement of equipment beneath an overhead service.
- Available utility records
- Proposed excavation and access
- Required field verification
- Utility-owner coordination status

Set observable handoff deliverables
An old utility drawing may omit later connections or provide approximate locations only.
| Input | Evidence to keep with it | Review status |
|---|---|---|
| Available utility records | Utility record source and date | Identify reviewer and written decision |
| Proposed excavation and access | Located conflict plan | Identify reviewer and written decision |
| Required field verification | Verification and owner coordination record | Identify reviewer and written decision |
Sequence review and release
Locate utility conflicts on the coordinated site plan and follow required notifications before affected work. Have qualified parties verify conditions using the applicable process. Route confirmed conflicts to civil, structural, and utility representatives for accepted disposition. Update excavation and access instructions and brief field leadership. If an unrecorded service appears, follow the project's stop and response process rather than assuming it is abandoned.
- Locate available utility records in the current record.
- Compare proposed excavation and access with the table's evidence.
- Document the decision: Resolve utility verification and conflicts before dependent excavation or access operations.
Worked project coordination example
A foundation trench crosses a service shown approximately on an old plan. The contractor follows the applicable locating process and coordinates the verified condition with the civil and structural team before proceeding.
Apply the stated release decision to the case: Resolve utility verification and conflicts before dependent excavation or access operations. The responsible team determines acceptance for the actual project and records any condition that still requires resolution.
Keep a closeout record another team can use
Keep utility sources, verification records, located conflicts, owner communications, and accepted changes together. Record actual service alterations in the site handoff and identify remaining coordination obligations. Do not let a relocated route remain only in a contractor's sketch. Future excavation teams need the updated information and its limitations. Preserve the distinction between a mapped service, a verified location, and an accepted construction disposition.
For this issue, include verification and owner coordination record in the handoff. If review remains pending, identify the dependent work and its owner; do not present the record as a completed technical acceptance.
Common questions
Does a record drawing guarantee a utility location?
No. Use required locating and verification procedures for the actual work.
How should available utility records be documented?
Resolve utility verification and conflicts before dependent excavation or access operations. Retain utility record source and date and check that the decision reached the team performing the dependent work.
