Development Infrastructure

Our Development Infrastructure team specialises in civil engineering, supporting clients across all stages of a project – from initial concept through to delivery and support on site – turning development visions into reality.

Sweco’s Development Infrastructure team has earnt an excellent reputation in the delivery of all civil engineering services. Our team consists of 10 driven people with over 120 years’ experience in the industry who are all instrumental in the delivery of our services. We work across a broad range of development and infrastructure sectors, including residential, water, energy, commercial, logistics and urban realm.

By combining technical expertise with a practical understanding of planning and construction, we help our clients de-risk projects, add value through intelligent design and deliver sustainable infrastructure solutions that perform well long-term. Our focus is on building strong relationships and working collaboratively with our clients to achieve their project goals, so that our clients become long-term trusted partners.

Our core development infrastructure civils expertise

With specialists across all areas of civils, we support clients across complex environments from residential, energy, commercial and public realm, applying long‑trusted technical expertise in delivery. We have worked with an extensive list of clients from all sectors and locations and are looking to extend our services outreach.

Ground, Land & Site Engineering

We unlock the development potential by reviewing ground investigation, levels and constraints that shape a site. From early feasibility through to detailed design, de-risk sites, optimise earthworks and create efficient buildable platforms for development.

  • Site appraisal, feasibility and constraints plans
  • Ground investigation report reviews
  • Earthworks, cut/fill optimisation and levels strategies

Water, Drainage & Flood Resilience

We help clients manage water as a resource and a risk, delivering compliant, sustainable drainage solutions and robust flood risk strategies. Our work supports planning approvals, protects assets and communities and builds resilience.

  • Surface water, foul and combined drainage systems
  • Sustainable Drainage Systems (SuDS) and blue‑green infrastructure
  • Flood risk assessment and mitigation (fluvial, tidal, surface water)
  • Drainage strategy
  • Hydraulic modelling and exceedance routing
  • Culverts, channels, outfalls and hydraulic structures
  • Climate resilience, flood adaptation and drought mitigation
  • S104 and S102 agreements

Access & Movement Infrastructure

We design safe, efficient and adoptable infrastructure, support placemaking and satisfy highways authorities to ensure a smooth adoption process. We understand the requirements sought from highways authorities, particularly the importance of intertwining active travel and SuDS into constrained proposals.

  • Highways and local road design from feasibility through to construction
  • Junctions, roundabout and access strategies
  • Pavement design and lifecycle asset management
  • Active travel and public realm infrastructure
  • Construction traffic management and logistics
  • S278 and S38 agreements

Utilities, Below‑Ground Infrastructure & Interfaces

We plan, coordinate and design utility infrastructure to ensure developments are deliverable, serviceable and future-ready. By managing interfaces and constraints early, we reduce risk, avoid clashes and support efficient construction.

  • Below‑ground services coordination and clash avoidance
  • Utilities diversion, protection and connection strategies
  • Cable corridors, ducting and trenching design

 Delivery, Buildability & Lifecycle Performance

We bring a delivery mindset to design, ensuring that civil engineering solutions are practical to build, safe to construct and value engineered. Our involvement from concept to handover helps control cost, risk and programme.

  • Constructability reviews and value engineering
  • As-built condition assessments
  • Whole‑life performance and maintainability planning
  • Early Contractor Involvement

Sustainable development infrastructure

The delivery of sustainable development is one of the key challenges for the 21st Century. Sweco’s engineers play an important role in key sustainability aspects such as SUDS and optimising use of site materials to reduce the need for importation and off-site disposal.

Our transport planning team, who balance the need for vehicular access with national and local policy requirements to limit parking and promote non car ‘active travel’ modes (public transport, cycling and walking), act as an integral part of a comprehensive Access Strategy.

Sweco also has significant capability in the urban energy and renewable energy sectors and can provide feasibility advice, detailed design and construction support services for low energy and renewable technologies such as Wind Power, Solar PV, Combined Heat and Power (CHP), District Heating (DH), Biomass, waste-to-energy plants and Anaerobic Digestion.

Together with our clients and the collective knowledge of our engineers, consultants and other specialists, we co-create solutions to address urbanisation, capture the power of digitalisation, and make our societies more sustainable.​ With international multi-disciplinary teams, we can call on the right insight and technical capability at the right time from across Buildings, Infrastructure, Advisory & Planning and Compliance.​
