Services
Detailed design and engineering is our primary service and pre-bid engineering is our second. Both apply across six infrastructure sectors and are delivered through two core disciplines: electrical, and civil and structural.
By engagement
Detailed design and engineering comes first and pre-bid engineering second. Studies, review and support are taken on as the contract defines.
Complete or partial post-award design for the electrical, civil and structural packages of a project: design criteria, calculations, drawings, schedules, BOQ and comment resolution through to final submission. This is our primary service.
Detailed Design & EngineeringSpecification and MDL review, preliminary SLD and layouts, quantity take-off, offer and GTP comparison, and clarifications, so an EPC bid is priced against stated assumptions. This is our second service.
Pre-Bid EngineeringLoad flow, short-circuit, insulation coordination, harmonics, transients, protection coordination, reactive power and grid interconnection studies, each offered on a stated basis.
Power System & Protection StudiesDesign checking, technical offer and GTP review, vendor drawing review, inspection and FAT witnessing, SCADA and interface engineering, and site, commissioning and O&M technical support, as contracted.
Technical Review & Project SupportBy infrastructure
Where we apply that work. Each sector page sets out scope, inputs, calculations, drawings and interfaces.
Electrical, civil and structural design for air- and gas-insulated substations and switchyards: new stations, bay extensions and interconnecting transformer yards.
AIS/GIS Substations & Switchyards
Solar PV systems, wind-farm electrical infrastructure, collector networks and shared evacuation, with the plant scope as actually contracted.
Solar, Wind & Hybrid Power Projects
Wind and solar pooling substations from collection to the grid interface, with the associated electrical and civil engineering, at 33/220 kV, 220/33 kV and other project voltages.
Pooling Substations & Power Evacuation
Utility-scale BESS sizing and configuration, electrical balance of plant, PCS and transformer interfaces, civil interfaces and grid integration.
Battery Energy Storage Systems (BESS)
Conductor and earth-wire selection, sag-tension and stringing charts, tower design, tower foundations and line-profile engineering.
Overhead Transmission Lines
Supporting engineering for bipolar and back-to-back schemes (service range up to ±512 kV / 2500 MW): AC-side, station and design-interface activities, as contracted.
HVDC SystemsBy discipline
Electrical and civil/structural are disciplines. Substations, renewable plants, storage, lines and HVDC are the infrastructure they serve.
SLD and Erection 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 & EngineeringSite 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 & EngineeringA defined discipline package, such as the electrical or civil design of a substation, taken through to final issue.
Earthing, bus calculations, a foundation design or a tower check, prepared against your design basis.
Vendor drawings, GTPs, offers or an existing design reviewed against the specification.
