Onyx & Iron reviews commercial underground utility scopes with general contractors, developers and property owners. Work is defined around the civil plans, utility requirements, site conditions and construction sequence.
Request a Scope ReviewProvide current civil drawings, specifications, utility schedules and relevant revisions. Identify the systems included, limits of installation, material requirements and any work provided by the owner, utility provider or another contractor.
Trenching, bedding, installation, backfill and related earthwork must be coordinated with existing utilities, access and adjacent construction. Depth, ground conditions, groundwater and required protective measures affect the scope.
Define who obtains approvals, arranges tie-ins or shutdowns, provides testing and coordinates inspections. A proposed schedule must account for the prerequisites and acceptance requirements established for the project.
Clarify surface restoration, paving limits, compaction testing, survey information and closeout documentation. Utilities need to be sequenced with grading, foundation work and concrete placement to avoid covering work before required acceptance.
Send the project address, civil plans, utility specifications, scope limits, current revisions, bid deadline and intended construction schedule. Include known existing utility information and testing or inspection requirements.
Responsibility for each item must be stated in the written scope. Utility-provider requirements, connections, testing, inspections and fees should be reviewed before assuming they are included.
Yes. We can review utility work as part of a civil site package with earthwork and concrete. The proposal should identify the sequence, required inspections and responsibility for making each work area ready.
Known conditions and available records are reviewed before pricing. The proposal should explain assumptions and the process for documenting and authorizing changes if unknown utilities, groundwater, unsuitable material or revised requirements affect the work.
Review our project photography and field footage. For your project, send the location, buyer type, plans and scope, access restrictions, desired schedule and proposed payment terms.
