Services Infrastructure
IF Infrastructure
The early development of utilities and energy strategies can have very significant benefits on delivery cost and programme, especially with regard early enabling works.


Our dedicated Infrastructure Services team specialise in the planning, design and procurement of utilities and decentralised energy services for major development and transportation projects to help ensure these benefits are achieved. Our specialist team consists of utility professionals with many years’ experience costing, designing and installing utility networks.

We have provided our services on a broad range of  projects to a varied client base, including  major economic and population growth planning projects for Local, Regional and National Governments. In addition we have provided infrastructure services for major London projects including Canary Wharf, the Olympic Park, Greenwich Peninsula and Royal Docks, as well as landowners and regional house-builders across a number of New Towns and Sustainable Urban Extensions.

At pre-development and pre-planning stage, our team works with utility undertakers, on behalf of our clients, to ensure that they produce fully coordinated composite multi-utility designs which are both deliverable and clash-free.

We are then skilled in the planning of phased decentralised energy projects that deliver heat, cooling and hot-water, typically from networked gas led combined heat and power (CHP). Our team design long-term water, wastewater and energy strategies that can be broken into Phased Delivery Strategies which maximise positive cash-flow outcomes for our clients.

Our comprehensive understanding of the utilities market allows us to significantly increase commercial value, reduce programme risk and enable our utility service provider partners to form an integrated part of the Design Team by ensuring that they fully understand a development’s commercial drivers.

Our Utilities Engineers, Contract Managers and Project Managers all have experience of managing the timely installation of new off-site and on-site water, wastewater, gas, electricity and telecommunications infrastructure. This activity includes Early Diversion Works, Enabling Works and Main Contractor activities.

Pre- Planning

  • De-risking development land in terms of existing utilities and utilities capacity constraints; particularly water, wastewater and power
  • Budget costs for utilities disconnections, diversions, new connections, networks extensions and off-site network reinforcement.

Design and Technical 

  • Concept planning and costing of new infrastructure services for iconic buildings and major development masterplans along with  city-wide and regional population/economic growth plans
  • Management of utility undertakers and utility contractors during disconnections, early enabling works, and through all RIBA stages of viability, design and construction, including commissioning, meter management and adoption.


  • Understanding of utility undertaker Deeds, Wayleaves, Leases and Covenants
  • Procurement of new water, gas, electricity and voice-data-video connections from both incumbent and independent utility network operators
  • Value-engineering of utilities’ proposals (from both incumbent and independent network operators)
  • Techno-economic viability of new decentralised energy systems (district energy led by gas CHP or heat pump arrays)
  • Procurement of new decentralised energy systems (district energy led by gas CHP or heat pump arrays)
  • Coordinated design of disparate water, gas, electricity and telecoms infrastructure through iterative dialogue with utility operators
  • Consolidation of outturn utilities costs.

Arborfield Green: Infrastructure

Arborfield Green is a new 2000-home ‘Garden Village’ incorporated into the regeneration of a former MOD Garrison Town, and includes new primary and secondary schools, a commercial centre, neighbourhood centres and a temporary Film Studios.

The client for the scheme is Crest Nicholson Regeneration and the Defence Infrastructure Organisation (DIO). Hilson Moran were initially appointed to support Crest Nicholson Regeneration in their commercial bid to become the DIO’s Development Manager, two years ahead of the outline planning application for this new Garden Village.

The initial workstream comprised of a viability study to understand the risks associated with the procurement of new water, wastewater, gas, electricity, and telecommunication services and to determine any abnormal costs. It also included risks and costs associated with diverting existing underground/overhead services. After Crest Nicholson were awarded the bid we were asked to support the outline planning application; preparing various Planning Statements, support the Design and Access Statement and some of the ES Chapters.

As part of the high-level strategic design team, we were appointed to work with the DIO and their utility supply chain to understand how the phased handover of the two operational barracks could be undertaken. This ultimately required the phased removal of private infrastructure and the phased installation of new public infrastructure whilst retaining critical services to operational MOD infrastructure and retained housing.

As part of the primary infrastructure team we prepared a number of phased strategic infrastructure masterplans, which have also been used in support of land sales to third party developers, and the film studio operator. These infrastructure masterplans were used alongside a bespoke technical specification to take to the independent multi-utility marketplace. We supported all mid-tender and post-tender discussions ahead of the appointment of an independent utilities partner. In addition, a bespoke ‘capital clawback’ mechanism was agreed with one of the incumbent utility undertakers.

We have also secured a number of appointments to undertake enabling works ahead of Reserved Matters applications for development parcels that have subsequently been brought forward. For each of these parcels we have also been commissioned to undertake tender and construction issue coordinated services detail.

Hilson Moran has also been appointed to deliver tender and construction stage design detail for some of the development parcels that have since been sold to third-party developers.

Hale Wharf: Infrastructure

Hale Wharf is a development of 505 residential units across a number of towers up to 19 storeys for Muse Developments and Canals and Rivers Trust trading as Waterside Places. The development is situated on a narrow brownfield island site located between a main river and a navigation channel. Our Infrastructure team undertook a number of exercises as part of the this large and complex project.

Initially, our team undertook a techno-economic viability study to understand District Energy options for the site: As such, we reviewed and advised the advantages of two options: The procurement of a new on site, self-developed energy services vehicle versus connection to a nearby district energy network, via a bridge, operated by a third party energy services special purpose vehicle.

Following this study, we also offered support in negotiating heat supply concession agreements and consumer agreements, as well as negotiation of capital costs, capital contributions and fixed and variable energy tariffs.

Early on, our infrastructure team was tasked with pre-planning viability works, providing a report and continuous advice regarding risks and costs associated with the alteration and diversion of utility services and relocation of existing electricity substations. We considered temporary and permanent solutions to allow site enabling and main construction works, thus ensuring the uninterrupted supply of water and power to a local canal boat community.

Hilson Moran also supported the technical specifications, tender negotiation and award of the enabling works contract. We developed the technical specification and an employer’s requirement document for the separate procurement of an Infrastructure Connections Provider (ICP) contractor to undertake the detail design and build (and subsequent adoption) of all new electricity infrastructure.

Ultimately Hilson Moran has identified technical and commercial risks associated with existing underground and over-ground utilities and the extension/connection of a local privately-owned district heat network that was previously unidentified. We continue to be engaged in the design and coordination of all new services infrastructure including construction-stage detailed coordinated services drawings.

Royal Albert Dock: Infrastructure

The Royal Albert Dock project entails the development of a new 4,000,000 sq ft business district by ABP (London) Investments Ltd in East London located opposite City Airport. With a contract value of £1.7B, a number of Hilson Moran’s design teams have worked on the scheme, including our Infrastructure Group.

Our Infrastructure Services team was engaged very early in the development of the masterplan and a number of pre-planning technical and commercial studies: We were able to take the ‘Hilson Moran Energy Statement’ and develop this into a tangible options study, setting out costs and risks associated with various district energy propositions. These included connections from a nearby off-site facility; an onsite facility developed under a design, build, operate and maintain Concession Agreement; and, interestingly, a developer managed Special Purpose Vehicle. All options were presented with planning, design, phasing, economic, procurement, and governance options and risks.

Our team also developed the design and technical specification for much of the Enabling Works Contract, which included the diversion of services around an existing DLR Station. We developed the design and technical specification for the onsite electrical infrastructure through an ICP; the onsite fibre infrastructure through the ‘Alt-Net’ and fibre ‘Carrier’ market; and developed the off-site electrical procurement strategy (under a LDDC Legacy Agreement) with UK Power Networks.

Hilson Moran developed the coordinated onsite services design, including; sewerage, district heating and district cooling networks, district fire-fighting, potable water, power, voice-data-video and all public realm security and lighting infrastructure; and put this into a fully 3D BIM model in Revit, from which 2D construction drawings were then provided.

Our team also coordinated the design and procurement of a fully connected smart public realm, to capture lighting, lighting control, security, EV Charging, public Wi-Fi and mobile telephony.

Barking Riverside: Infrastructure

Located on the site of the former Barking Power Station (a 180 hectare brownfield site with 2km of river frontage), this development is one of the UK’s largest urban regeneration projects and includes a £263million rail extension within its boundary. The masterplan aims to provide over 10,000 new residential homes (Stages 2, 3 and 4 contain 9,484 new homes, a new District Centre, new Neighbourhood Centres, a Port Quarter, leisure facilities, shops and restaurants; effectively 65,000 m2 of commercial space). The whole development will transform a former industrial part of east London and shift the centre of London eastwards.

Hilson Moran’s specialist utilities team (Infrastructure Services) has undertaken a number of discrete workstreams all relating to utilities and energy infrastructure.

Initially – and innovatively – Hilson Moran was initially asked to develop a temporary power and water strategy in order to limit the expenditure on new connections to the existing network, and limit the need to secure additional off-site power given the need to provide temporary power to;

  • Multiple site offices
  • Multiple welfare facilities
  • Marketing suites
  • Multiple concrete silos and tower crane hubs

Hilson Moran therefore developed a temporary services strategy – both schematically and spatially – so that the whole of the temporary works (particularly the actual building supplies – silos and cranes) could roll north to south and east to west through the site over an initial 5 year and then 15-year build programme. This work was undertaken wholly in conjunction with BRL and their groundworks / temporary works contractors, and taken to the utility undertakers for modification and approval as required. A 2nd iteration of this strategy has just been completed by Hilson Moran and BRL.

Hilson Moran next developed the Utilities Planning Statement in support of the Primary Infrastructure Reserved Matters planning application: This Statement provided details of all the likely alterations to existing utilities infrastructure; and more strategically it provided detail (with evidence from utility undertakers) of the proposed strategy for providing water, heat, power and voice-data-video services to 9,484 new residential dwellings plus associated district and neighbourhood centres, including all public realm.

This Planning Statement also included water and power services for critical infrastructure including – for example – vacuum waste collection, lighting, EV charging, and foul pumping stations.

The utilities planning statement was developed into a Preliminary Infrastructure Appraisal capturing budget costs and risks (financial and programme) associated with the phased delivery of water, power, heat and telecommunications. This included all onsite and off-site risks associated with limited supply capacity and utility investment needs, including the Bilateral Capacity Agreement between SSE and UKPN.

To deliver the Planning Statement and subsequent costs/risks associated with the design and procurement of water, gas, heat, electricity and telecommunications to support 9,484 new homes we had to review water, power and heat requirements at a typical dwelling-level; block-level; parcel-level; district-level and phase-level; and apply diversity at each level in agreement with the incumbent utility undertakers, and each of BRL’s preferred utilities partners (SSE Enterprise, Vital Energi, Envac, Openreach, Virgin and SSE Networks). In addition we had to review landlord needs, electric vehicle charging needs, and future demand-side management/storage need (the district heating network will initially fed by gas CHP).

Barking Riverside Limited has most recently sought from Hilson Moran’s specialist utilities team a series of Design Codes that can be used by the parcel Developer to design the HV and other primary infrastructure within each development parcel. In effect we have broken the site-wide utilities strategies into phases and districts, and for each district provided an HV solution with numbers, locations and technical specifications for each substation in order that the parcel developers can capture the substation needs and ensure that all in-parcel distribution infrastructure would work. For the District Centre these Design Codes are created for high-rise apartments, mid-rise apartments and town-houses for each service type (water, heat, power and telecoms).
