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
• Busbar and bay arrangement design
• Cable route and trench profile design
• Foundation, steelwork and building 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 NGTS and BS
• Cable routes and trench profiles
• Civil and structural design packages
• 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 checked against the governing specification, 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. That is unusual at this voltage range, and it means layouts, foundations and steelwork are coordinated from the first issue rather than reconciled at the end.
