Utility Diversions for Construction Projects

Gas, water, and electricity diversions delivered under one contract, in one trench, with one traffic management scheme. 25 to 40% cost savings vs separate contractors.

The Process Step by Step

Every utility diversion follows a clear, auditable sequence. Here is exactly what happens at each stage.

1

The Multi-Utility Advantage

When gas, water, and electricity diversions are placed with separate contractors, each contractor opens its own trench, operates its own traffic management scheme, and drives its own design through a separate approval process. This means three mobilisations, three TM schemes, three sets of reinstatement, and three separate programmes running in sequence or in conflict. USP holds NERS, GIRS, and WIRS accreditations, allowing all three utilities to be designed, approved, and installed under one contract, in one trench, with one traffic management scheme. This is the foundation of the 25 to 40% cost saving.

2

Asset Detection and Survey

Before any design work begins, USP carries out a full asset detection survey. Desktop records are obtained from all three network operators. Electromagnetic detection is used to locate buried services, and vacuum excavation is used for physical verification at key points. This prevents design errors that can cause costly redesign after ground investigation, and reduces the risk of service strikes during construction.

3

Diversion Design and Approval

USP prepares the diversion design for all three utilities simultaneously and submits to all three network operators in parallel. This prevents the sequential delay that occurs when designs are submitted separately and each operator waits for the previous one to complete. Coordinated approval means the programme starts from a single design approval milestone rather than three separate ones. USP manages the approval process with each operator and resolves technical comments without escalating to the client.

4

Combined Delivery

Installation is sequenced within a single trench opening, with each utility laid at the correct depth and separation in accordance with the HSG47 guidance and individual network operator specifications. A single traffic management scheme covers the full working area. All three utilities are tested and commissioned simultaneously where the programme allows, and as-built records are produced for all three utilities in a single handover package. USP issues these records to each network operator for asset register update and to the Principal Contractor for the CDM health and safety file.

NERS (electricity), GIRS (gas), and WIRS (water). USP holds all three in-house with no subcontracting.
Asset detection
Electromagnetic survey followed by vacuum excavation for physical verification at key points before design begins.
Design approvals
Submitted to all three network operators in parallel to avoid sequential delay. USP manages technical responses.
As-built records
Produced for all three utilities in a single handover pack, issued to each network operator and to the CDM health and safety file.

Utility Diversions FAQs

Frequently Asked Questions

With separate contractors, each utility opens its own trench, operates its own traffic management scheme, and sends its own design through a separate approval process. Each mobilisation also carries its own fixed costs. By combining all three into one trench, one TM scheme, and one programme, USP typically saves clients 25 to 40% on total civils costs and significantly shortens the programme.
Yes. USP holds NERS (electricity), GIRS (gas), and WIRS (water) accreditations, making us one of the very few multi-utility ICPs in the West Midlands with all three. This means no subcontracting for individual utilities and no gaps in accountability.
Typical savings are 25 to 40% compared with appointing three separate contractors. The saving comes primarily from shared civils (one trench, one backfill, one reinstatement) and shared traffic management. On schemes with complex TM requirements the saving can be higher because TM is often the most expensive single cost on a diversion project.
Each utility has a non-contestable element that must be carried out by the network operator itself. Gas hot taps and pressure tests, electricity cut-ins and energisation, and water pressure testing and chlorination are all coordinated by USP with the relevant network operator. USP manages the programme so all three non-contestable works are scheduled together where possible.
USP produces as-built drawings for all three utility diversions and issues them to each network operator for asset register update. These documents are also required for the CDM health and safety file. Pressure test records, chlorination certificates, and electrical commissioning records are all included in the handover pack.
