Detailed Engineering & Design
Post-award design criteria, calculations, drawings, schedules, BOQ and comment resolution through to final submission. Our main commercial service.
Detailed Engineering & DesignServices
Engineering Services
Detailed engineering and design is our primary service, with pre-bid engineering as the next engagement. Both apply across six infrastructure sectors, delivered through two core disciplines: electrical, and civil and structural.
By engagement
Engineering services
What we do for a project, from tender to post-award design and site support.
Pre-Bid / Tender Engineering
Specification and MDL review, preliminary SLD and layouts, quantity take-off, offer and GTP comparison, and clarifications for EPC bids.
Pre-Bid / Tender EngineeringEngineering Studies
Earthing, lightning protection, short circuit, load flow, insulation coordination and other studies, each offered on a stated basis.
Engineering StudiesEquipment, GTP & Offer Review
Technical evaluation of supplier offers, GTP and vendor drawing review, and inspection and FAT witness support where contracted.
Equipment, GTP & Offer ReviewSite, Commissioning & O&M Support
Site and vendor query responses, SCADA signal mapping, commissioning advisory and O&M technical support, as contracted.
Site, Commissioning & O&M SupportBy infrastructure
Infrastructure sectors
Where we apply that work. Each sector page sets out scope, inputs, calculations, drawings and interfaces.
Substations & Switchyards
Electrical, civil and structural design for AIS and GIS substations and switchyards: new stations, bay extensions and interconnecting transformer yards.
Substations & Switchyards
Solar, Wind & Hybrid Plants
Plant electrical balance of system, collection networks, plant layout interfaces and grid connection for solar, wind and hybrid projects.
Solar, Wind & Hybrid Plants
Pooling Substations
Pooling and evacuation substations that collect renewable output at 33 kV and step it up to 132 kV, 220 kV or higher for the grid.
Pooling Substations
Battery Energy Storage
BESS sizing, PCS and transformer interfaces, auxiliary systems, protection and SCADA interfaces, and connection to pooling or grid substations.
Battery Energy Storage
Transmission Lines
Line electrical design, single and double circuit tower design, sag-tension and stringing, and tower foundations by soil class.
Transmission Lines
HVDC Engineering
Converter-station engineering, equipment specification and review, and study support for bipole and back-to-back schemes, as contracted.
HVDC EngineeringBy discipline
Engineering disciplines
Electrical and civil/structural are disciplines. Substations, renewable plants, storage, lines and HVDC are the infrastructure they serve.
Electrical Design & Engineering
SLD and key diagrams, AIS/GIS layouts, conductor and busbar calculations, earthing and lightning protection, equipment ratings, auxiliary AC/DC, cables, illumination, and protection and SCADA interfaces where in scope.
Electrical Design & EngineeringCivil & Structural Design & Engineering
Site grading, steel structures, equipment and transformer foundations, oil containment, control and GIS buildings, cable trenches, drainage, roads and fencing, with reinforcement drawings, BBS and quantities.
Civil & Structural Design & EngineeringWays to engage
A complete package
A defined discipline package, such as the electrical or civil design of a substation, taken through to final issue.
An individual calculation or drawing set
Earthing, bus calculations, a foundation design or a tower check, prepared against your design basis.
Review and checking
Vendor drawings, GTPs, offers or an existing design reviewed against the specification.
