Substation and primary design

The problem this solves

Substation projects fail at interfaces: between electrical and civil design, between concept and buildable layout, and between what a specification requires and what a drawing actually shows. Clients need a design package that a network operator will accept and a contractor can build without rework.

Project types we support

• New primary and grid substations, 11 kV to 400 kV
• Substation extensions, replacements and reconfigurations
• AIS and GIS arrangements
• Utility, IDNO and private wire substations

Design, calculation and study work

• Single line diagrams and protection block diagrams
• Electrical clearance assessments to BS EN 61936-1 and operator specifications
• Busbar and bay arrangement design
• Cable route and trench profile design
• Foundation, steelwork and structural design (in-house civil and structural)

Deliverables

• Single line diagrams through to full substation layouts
• General arrangement and section drawings, AIS and GIS
• Electrical clearance assessments to BS EN 61936-1 and operator specifications
• Cable routes and trench profiles
• Civil and structural design packages, independently checked
• Designer risk assessments and CDM 2015 designer information
• Design documentation to DNO and transmission specifications

How this reduces risk

A coordinated electrical, civil and structural design removes the interface gaps that cause site rework, clearance infringements and programme slip. Designs are produced and independently checked against the governing specification, and designer duties under CDM 2015 are discharged as the design develops, so acceptance by the network operator is a review, not a negotiation.

Why appoint Saqib Engineering

Electrical, civil and structural design are produced by one team under one design governance process, with civil and structural work carried out in-house and independently checked. Layouts, foundations and steelwork are coordinated from the first issue rather than reconciled at the end.

Common questions

Do you carry out civil and structural design in-house?

Yes. Foundations, steelwork and substation structures are designed in-house and independently checked, so electrical and civil design are coordinated from the first issue rather than reconciled at handover.

What voltage levels do you design substations for?

We design primary and grid substations from 11 kV to 400 kV, in both air-insulated (AIS) and gas-insulated (GIS) arrangements, for utility, IDNO and private wire networks.

Do you take substation designs through to construction issue?

Yes. We take substations from single line diagram to construction-ready layout, with electrical clearances assessed to BS EN 61936-1 and the operator specification, and designer duties under CDM 2015 discharged as the design develops.
