How to Choose the Right Partner for Your Next Civil Project

How to Choose the Right Partner for Your Next Civil Project

Choosing a partner for civil work can feel overwhelming. Big stakes, tight schedules, safety rules, and community pressure create a lot of moving parts. We’ve helped teams navigate choices like this many times, and want to share a clear, practical path that helps project leaders pick a partner who delivers on time, on budget, and with quality. Why partner selection matters Good partners reduce risk. Poor choices create delays, cost overruns, and reputational damage. That’s why an upfront, structured approach saves money and stress later. Use these steps to compare firms honestly and pick a team aligned with goals. Start with clarity: define scope, outcomes, and priorities Before contacting firms, answer three questions together: When scope and priorities stay clear, proposals become comparable. That makes shortlisting easier. Evaluate technical capability and delivery experience Look beyond glossy brochures. Ask for concrete evidence: For example, reading about large-scale urban transformation projects can show how design and delivery teams coordinate on complex sites. Review case studies carefully to understand problem solving under pressure: scope changes, utility clashes, or tricky access. See a recent example of coordinated teams tackling massive transformation here: large-scale urban transformation projects. Check track record: safety, schedule, and claims history Safety and time performance tell a lot. Investigate: Ask previous clients about responsiveness during surprises. Firms that communicate clearly under pressure earn trust. Assess resourcing and supply-chain resilience Availability of equipment, skilled crews, and suppliers often determines success. Verify: Also consider firms with flexible resourcing in nearby regions. They often avoid costly downtime. Sustainability, climate readiness, and long-term performance Regulators and communities expect resilient infrastructure. Prioritize partners who can: For those wanting evidence of strong delivery systems and governance, reviewing project management best practices helps. That gives insight into how teams handle lifecycle risk and asset handover. Explore perspectives on delivery and governance here: project management best practices  Quality assurance, testing, and compliance Quality processes matter from day one. Confirm partner can provide: Good handovers reduce future maintenance drama and cost. Communication, culture, and collaboration style Technical skill won’t save a project from poor teamwork. Use interviews to assess culture: Choose partners who match your communication rhythm. That keeps decisions moving. Commercial clarity: pricing, contracts, and incentives Compare proposals on apples-to-apples basis: Commercial fairness encourages innovation while protecting client interest. Local knowledge versus specialist skills Local firms bring regional know-how, permitting networks, and community relationships. National or international specialists offer niche capabilities and deep technical experience. Often, best outcomes come from blended teams that pair local insight with specialist expertise. When a civil specialty becomes essential—say complex piling or wetland restoration—check specialist portfolios and field references. For instance, when earthworks and drainage form project backbone, firms such as Solve Civil show how specialty providers support robust site delivery. Decision checklist: questions to ask final candidates Before awarding contract, confirm these items: Use scorecards to rate responses objectively. That avoids bias. Onboarding: set partnership up for success After selection, run a short onboarding sprint: Early alignment prevents costlier fixes later. Final thoughts Choosing right civil partner shapes project outcome more than any single technical decision. Focus on clarity of goals, proven delivery, resource resilience, and cultural fit. Use structured interviews, scorecards, and targeted reference checks to remove guesswork. When specialized skills matter, linking with experienced civil specialists helps fill gaps without compromising accountability. For teams wanting examples of specialty delivery on earthworks and drainage, consider how external firms integrate with main contractor teams to boost capacity without losing control. If readers want a printable checklist or a sample interview scorecard, we can share one on request. Our goal remains simple: help project leaders choose partners who build durable infrastructure, protect budgets, and earn community trust.

STRABAG awarded contract by United Utilities to deliver the Haweswater Aqueduct Resilience Programme (HARP)

STRABAG awarded contract by United Utilities to deliver the Haweswater Aqueduct Resilience Programme (HARP)

STRABAG are pleased to announce that they have achieved financial close and have been awarded the contract to deliver the Haweswater Aqueduct Resilience Programme, otherwise known as HARP, for United Utilities. HARP is a major scheme to maintain drinking water supplies across Cumbria, Lancashire and Greater Manchester for future generations. The Haweswater Aqueduct is a 110km pipeline which runs from the Lake District, through Lancashire and into Greater Manchester. Originally constructed between 1933 and 1955, the pipeline needs essential upgrade work and will see the replacement of the existing tunnels sections. The overall estimated project construction costs will be in the region of £3bn. The complex construction and maintenance programme is the first in the UK water sector approved by Ofwat to be delivered through a Direct Procurement for Customers (DPC) model. The infrastructure project will bring a range of economic benefits to the region and will create local jobs and apprenticeship opportunities. STRABAG, alongside its partners Equitix and GLIL Infrastructure, have formed Cascade Infrastructure Ltd, the project company responsible for the project agreement with the client, United Utilities. The contract includes finance, design, build and maintenance of six tunnel sections of the pipeline. STRABAG UK Limited will deliver the full design and construction scope of the project. The build phase is planned to run over nine years followed by a further 25 years of maintenance. STRABAG CEO, Stefan Kratochwill said: “Expanding our presence in the UK and investing in critical water infrastructure is a clear step in delivering on our Strategy 2030. With HARP, we are not only contributing to the long-term resilience of critical infrastructure, but also strengthening our market position in the UK”. STRABAG UK Ltd Managing Director, Simon Wild, added: “The award of the HARP design and construction contract to STRABAG UK Limited recognises the capability and depth of competence we have built up over the past years. We will deliver this critical national infrastructure focussing always on best value, working closely with local communities and creating high quality opportunities for skills development and long-term employment in the North of England. We are immensely proud of the way our teams have collaborated to achieve financial close and look forward to continuing this partnership for years to come on such a significant project.” Louise Beardmore, Chief Executive at United Utilities, said: “Making the North West stronger, greener and healthier is at the heart of everything we do. Today marks a significant step to ensure we have the right infrastructure to provide a resilient water supply to communities right across the region for decades to come and, at the same time, creating hundreds of great quality jobs and delivering on the commitments and promises we have set out.” Additional Information In PR19, Ofwat developed the Direct Procurement for Customers (DPC) approach, building on the success of Thames Tideway Tunnel. DPC involves a water or wastewater company competitively tendering for services in relation to the delivery of certain major infrastructure projects, resulting in the selection of a third-party competitively appointed provider or ‘CAP’ who will design, build, finance, and in some circumstances operate and/or maintain the relevant infrastructure. DPC will result in water companies competitively procuring more aspects of an infrastructure project, including financing for the project. The original 110km pipeline was constructed between 1933 and 1955 by the Manchester Corporation – the then local authority. The renewal programme will see the six tunnel sections replaced.

Bridge Beam installation marks key milestone in Stockton Waterfront construction

Bridge Beam installation marks key milestone in Stockton Waterfront construction

New land bridge to provide level access route through urban park to connect the High Street to the River Tees. Esh Construction has marked a significant milestone in the transformational Stockton Waterfront urban park project with the installation of the precast beams to form a new land bridge being completed. The North of England contractor is carrying out the £23 million urban park on behalf of Stockton-on-Tees Borough Council. The project is a major part of the Council’s blueprint for the regeneration of Stockton over the next 25 years. Upon completion, it will feature a series of green, flexible spaces capable of hosting events and impressive, unique play areas, transforming the High Street and providing uninterrupted access to the riverside. With paving works progressing at pace along Finkle Square in the upper park, works to connect the High Street to the River Tees via a new land bridge and Millennium Bridge, have taken a significant step forward. A total of 47 prestressed concrete bridge beams have been installed with support from reinforced concrete specialists BEMAC Construction, to form the land bridge above the A1305 Riverside Road carriageway. The beams, which were manufactured by Shay Murtagh Precast Ltd in the Republic of Ireland, include 45 standard units measuring 21.5 metres in length and weighing 17 tonnes, alongside two edge beams which weigh 35 tonnes each. David Player, Contracts Manager at Esh Construction, said: “The bridge beam installation is a key milestone in the Stockton Waterfront project and a testament to the collaborative planning and engineering expertise of all involved. “With the beams in place, we can now move forward with casting the bridge deck and progressing the next phase of public realm works that will bring the land bridge to life.” A 200-tonne crane was used to lift the 47 beams into position over four days, with the heaviest lift taking place at an 11-metre radius. Ahead of the installation, Esh Construction’s project team visited Shay Murtagh’s manufacturing facility in County Westmeath to inspect the cast beams, review the quality assurance process, and ensure compliance with project specifications. Working closely with the specialist precast concrete provider, robust plans were then implemented to ensure safe delivery of the product in line with the installation schedule. Steve Lowe, Chief Structural Engineer at Shay Murtagh Precast Ltd, explained that the beams for this project are environmentally advanced with concrete using 40% GGBS replacement of Portland cement making them a significantly carbon efficient option. He added: “It was great to bring our technical expertise to this project and support Esh Construction in the beam and bridge deck installations, which will enable the next construction phase of the development of the land bridge and support the urban park’s progress for Stockton-on-Tees Borough Council.” With the beams forming the base for the 55-metre-wide land bridge above the realigned Riverside Road, the next phase of works will involve pouring 170m3 of concrete to cast the bridge deck, followed by the installation of 163m2 of porphyry paving, 420m2 of resin and 75m2 of granite paving to create a seamless public realm open space. The project will create an iconic, nationally recognisable new public space for the Borough’s residents and visitors and is part of Council ambitions to make Stockton-on-Tees a place of choice for people to live, work and visit. Councillor Richard Eglington, Cabinet Member for Regeneration and Housing at Stockton-on-Tees Borough Council, said: “It’s very exciting to see the progress of the transformation of the Stockton Waterfront site taking place and this important milestone helps make the vision of reconnecting the High Street to the river more of a reality. “The scale of change will also be felt across the entire Borough. Stockton Waterfront is set to be the catalyst for further regeneration work across Central Stockton and North Thornaby and we are looking to build on this success to create a thriving place for our communities and businesses.” In the coming months, residents and visitors will see marked changes on the site as works commence to install the amphitheatre and landscaping elements across the lower park, while construction of a new play park in the upper park is also set to begin. Procured via North East Procurement Organisation (NEPO), Esh is working with design partners Ryder Architecture and Billinghurst George & Partners to deliver the project.

Transpennine Route Upgrade receives electrification works

Transpennine Route Upgrade receives electrification works

The Transpennine Route Upgrade (TRU) has reached a significant milestone, following five consecutive weekends of intensive engineering work between Leeds and York to advance electrification of the line. As part of the ongoing upgrades, engineers have now installed 7.5 kilometres of overhead line equipment (OLE) wiring between Micklefield and Church Fenton. This latest progress builds on earlier mast installation and is key to delivering faster, greener rail journeys across the north of England. The electrification work in this stretch brings the project a step closer to connecting electric passenger services between York and Church Fenton, due to launch in the coming months. This follows the successful introduction of electric services between Manchester Victoria and Stalybridge in 2024. In Cross Gates, major infrastructure improvements were also completed, including the safe demolition and replacement of the Station Road bridge, clearing the way for future OLE installation in the area. Elsewhere, around 750 metres of track have been renewed between Killingbeck and Cross Gates, supporting smoother and more reliable services. A new track crossover was installed to improve operational flexibility, enabling trains to switch lines and maintain service continuity during future construction phases. Adam Sellers, senior sponsor for TRU, said: “This latest series of upgrades has taken us a step closer to the electrification of the route between York and Manchester. Wiring is now in place in the Barkston Ash area, whilst Cross Gates station can now facilitate the installation of OLE masts. “Work to deliver cleaner, greener services throughout this area will continue throughout the year, whilst attention also turns to the introduction of electric passenger services nearby, which is another huge milestone for the programme.” Building, Design & Construction Magazine | The Choice of Industry Professionals

Balfour Beatty VINCI completes slide of the ‘East Deck’ for HS2’s M6 South Viaduct

Balfour Beatty VINCI completes slide of the ‘East Deck’ for HS2’s M6 South Viaduct

Balfour Beatty VINCI has successfully slid the first part of a major 320-metre-long viaduct into position that will carry high speed trains across the M6 near Birmingham Airport. The first stage of the project – delivered this weekend – saw the ‘East Deck’ of the M6 South viaduct slid 119m out over a slip road adjacent to the motorway. To reduce disruption for motorists, the viaduct deck is being assembled to one side and slid across the motorway over three weekends, with each part pushed out before later sections are added behind them. This multi-stage process means that the weight of the deck will increase with each push from 1,3000 tonnes this weekend, to 3,290 for the final slide. These subsequent slides will take the deck out over the main M6 carriageway and then finally the M6-M42 link roads. The weight includes pre-cast concrete deck slabs on top of the steel structure. Launching the viaduct with the deck units already in place further reduces the number of closures of the motorway. The East Deck will carry two tracks taking trains towards London while an adjacent ‘West Deck’ will carry a further two tracks for services heading to Birmingham and further north. This will be assembled and slid out next year using the same technique. Russell Luckhurst, the Balfour Beatty VINCI’s engineer leading the delivery of the works, said:“This complex viaduct spanning the M6 motorway and adjoining slip roads is really beginning to take shape, now we’ve successfully moved the first section into place. “It’s a huge achievement for the dedicated project team who’ve worked tirelessly over the past three years to reach this point. We’re now focussed on delivering the next phase, which includes two further launches later in the year.” Liam Kenney, HS2 Ltd’s Senior Project Manager said:“It’s great to see the first section of the East Deck in position over the weekend. Once complete, these twin viaducts will carry high speed trains over the M6 helping to improve journeys and free up space on the existing rail network for more freight and local services. “I’d like to thank everyone who is worked so hard to deliver the first slide safely and efficiently opening the road to traffic 11 hours early. The complex operation is being led by Balfour Beatty VINCI, supported by specialist steelwork company Victor Buyck Steel Construction (VBSC). The team are working closely with National Highways and other key local stakeholders including the NEC and Birmingham Airport. Victoria Lazenby, National Highways Regional Director for the Midlands, said:“We know that any work on our roads affects drivers and local communities and always try to keep that disruption to a minimum. So we are delighted by the innovation shown by HS2 and BBV in this complex engineering feat to reduce the impact on road users. “We will continue to work very closely with HS2 to ensure minimum disruption on our roads and are grateful to people for their patience while this major infrastructure scheme is delivered.”  The viaduct section was moved using a series of winches, known as strand jacks, at an average speed of twelve metres per hour, sliding across non-stick pads to reduce friction – a material usually found to the surface of a household frying pan.  A 36-metre-long temporary launch nose was installed to the front of the structure, to guide the viaduct on its launching path and reduce the weight of the cantilevered section. The viaduct, and the launch nose, will remain in its current position while the next section is assembled. The viaduct is restrained temporarily by equipment located on the piers and the abutments. Each viaduct span is formed of a hollow double-box structure made of weathering steel. This kind of steel boasts a natural protective layer of oxidisation which gives it a characteristic ‘rusty’ appearance and reduces maintenance by eliminating the need for regular repainting. Four pairs of concrete piers support the viaducts with tallest one 9.9m in height. A 4.5m high parapet will be provided on the side facing the Chelmsely Wood to reduce noise and disturbance from passing trains. The structural design has been carried out by Balfour Beatty VINCI’s Design Joint Venture, made up of Mott MacDonald and SYSTRA. Tom Dutton, Senior Design Co-ordinator for the Mott MacDonald SYSTRA DJV, said:   “The launch of the first deck of the two-deck M6 Motorway South Viaduct marks an exciting milestone following years of dedicated design work. We have seen the design take shape as the foundations, piers, and abutments were constructed, and now the moment has arrived for the deck to be launched.   “The launch design is a fantastic example of collaboration between Mott MacDonald SYSTRA DJV colleagues in the UK and France, BBV, and their steelwork and launching contractor, Victor Buyck Steel Construction. Together, we have addressed the complex challenges of the temporary works and the fabrication of the steel diaphragm—not to mention the feat of launching the viaduct decks over the M6 motorway itself. “This achievement is a testament to our collective effort and a fantastic milestone for the immediate team and the whole project.” Building, Design & Construction Magazine | The Choice of Industry Professionals
