Technical Review & Project Support

Design checking, technical offer and GTP review, vendor drawing review against the approved specification, inspection and test witnessing, SCADA and interface engineering, and site, commissioning and O&M technical support, so deviations are raised before they become site problems.

What the review covers

Suppliers submit offers, data sheets and drawings that must agree with the specification the project is built to. A review compares what is offered with what is required and records the result in a form the EPC team or owner can act on. It happens at two points: during the bid, when offers are compared and scope gaps priced, and after award, when vendor drawings are checked before they are approved and used for design.

The same work applies to substation equipment, renewable plant and BESS equipment, line materials and HVDC station equipment. Where we prepare or review technical specifications for a client, we do so as its engineering consultant; approval of specifications and documents remains with the party the contract names.

  • Preparation and review of technical specifications
  • Bid-stage offer comparison and technical evaluation
  • GTP review against the specification
  • Vendor drawing review for dimensions, loads and interfaces
  • Review of detailed engineering reports and calculations by others
  • Technical query and comment resolution tracking

Typical review checks

The checks are drawn from the project specification; we do not substitute our own criteria for the approved ones.

CheckTypical question
Ratings and performanceDo rated values meet the specification and system data?
Dimensions and clearancesDo overall dimensions and clearances fit the layout?
Terminal and foundation loadsAre loads and anchor details given for civil design?
InterfacesDo cable entries, earthing points and bushings match the design?
Test dataDo type and routine test reports cover what the specification requires?
DocumentationDo drawing lists and data sheets match the MDL and the specification?
Scope and exclusionsWhat is included, excluded or left to others?

Inspections, audits and test witnessing

Where the contract includes them, we support quality assurance beyond document review: vendor qualification and supplier audits against the project’s criteria, and witnessing of type, routine and factory acceptance tests (FAT). Witness reports compare results with the approved data and record observations for the client.

  • Vendor qualification and supplier audits
  • Type and routine test review
  • Factory acceptance test (FAT) witnessing
  • Inspection and witness reports
  • Third-party inspection support, as contracted

Outputs

Review sheet

A point-by-point record of compliance, deviations and information still required, linked to the document and revision reviewed.

Offer comparison

Technical comparison of offers on a consistent basis, with differences in scope, ratings and exclusions noted.

Witness and audit reports

Where contracted, records of tests witnessed and audits carried out, with observations for the client.

Responsibilities. A review does not transfer responsibility for the supplier’s design. Technical acceptance, approval and commercial evaluation remain with the client, owner or EPC contractor as the contract defines.

Project support

Taken on as each contract defines. None of it is assumed to be part of a detailed engineering package.

As contracted

Construction-stage engineering

Responses to site and vendor queries against the approved design basis, with revised drawings where the answer changes the design.

As contracted

SCADA and interface engineering

Signal lists and mapping sheets that follow the client’s control system design. Control system configuration stays with the system supplier.

As contracted

Commissioning and O&M support

Review of test procedures, witnessing of site tests, commissioning advisory and O&M engineering advisory.

Site, commissioning and O&M support in detail

Send the offer, GTP or drawing set you need reviewed

Share the specification clause list, the supplier documents and the date by which comments are needed. We will confirm the checks we can complete in that time.
