Walsh is a leading London based civil, structural and geotechnical engineering consultancy focused on providing elegant, buildable solutions to complex engineering problems.
With over 130 staff and projects of over £800m in value, Walsh has been at the forefront of the construction industry for over 30 years and grown to become one of the UK’s leading practices.
Walsh applies lean design principles to every project, helping client to achieve the optimum economic and sustainable solution without inhibiting the architectural vision. We collaborate closely with the wider design team, taking a holistic approach and proactively seek to de-risk developments at every turn.
Our clients include the largest UK developers who value us for our honest pricing model which provides them cost surety and our fees are often recouped many times over with the savings our designs deliver.
Find out moreWalsh has delivered a wide variety of schemes from residential, commercial and mixed use ,to specialist areas like retail, student accommodation, build-to-rent, science and industry, healthcare and more. With expertise spanning the full range of development types, our multi-disciplinary engineers can bring their experience of best practise and innovation in one sector and apply it to another. This helps our clients minimise risk, reduce cost and shorten programme whilst maximising value and improving sustainability.
View AllWalsh works with many of the largest well-known homebuilders in the UK. Our private residential experience spans bespoke one-off projects to £450m+ developments that are amongst some of the most challenging and constrained site in the country. We optioneer schemes at an early stage to recommend the best and most sustainable methods of construction including foundation, buildability and safety aspects whilst delivering the detailed design stage using a collaborative approach,
Walsh has delivered engineering solutions for millions of square feet of commercial space over the last 30+ years. Whether these commercial buildings are to be located in urban environments or at regional business parks, we understand the dynamics that are reshaping our cities and workplaces. We design to meet the economic, human health and sustainability requirements of occupiers today whilst considering the potential needs of future occupiers.
Walsh has been at the forefront of Design for Manufacture and Assembly (DfMA) and innovative techniques using MMC for many years. On turnkey projects, like the Mace ‘Rising Factory’, Walsh has designed systems that allow multiple floors to be built in just a few days and saved months on the programme. Walsh has completed schemes in Concrete Frame, Modular HRS RC Frame, Full Volumetric Frame, Precast Frame, CLT and Steel Concrete Hybrid Frame.
Our attention to detail and ability to deliver on time has made Walsh the “go-to” engineers of choice in the UK for purpose built student accommodation. Walsh has successfully delivered the engineering consultancy that has facilitated more than 50 PBSA developments providing nearly 30,000 student beds with many more in planning or under construction. Our value-added approach on these projects has provided significant environmental, programme and financial benefits to our clients.
Sustainability is in our DNA and we have our own ambitious goals to achieve Net Zero as a business and with our designs. With innovative in-house monitoring tools, Walsh clients have seen on average reductions of 10-20% total embodied carbon, with some of our flagship work achieving 60-70% reductions compared with baseline figures.
Find Out MoreWalsh offers Geotechnical engineering and Geoenvironmental engineering consultancy focused on sustainable, buildable solutions for our clients from project inception through to completion.
Our Geotechnical engineering team has a combined experience of over 35 years, delivering complex geotechnical and contaminated land developments in London and around the UK. Geotechnical services can be commissioned as standalone studies or as a seamless extension to the wider civil engineering and structural engineering services offered by Walsh.
This major office development in Stratford provides over 300,000 square feet of commercial space and consists of a 14 storey office block over a ground floor amenity space above a 7m deep basement. Working on a heavily constrained site, Walsh designed a lightweight structural solution to speed up construction and a an embodied carbon footprint 20% below industry good practice. This earned the development a BREEEAM Excellent rating.
Walsh were uniquely placed to design an innovative range of both concrete and steel solutions and advise on the ground remediation of this former gasworks site. Walsh were able to develop a standard frame system across the residential sites on this prestigious multiple phase mixed use development using long span P.T flat slab construction that allowed flexibility for apartment layouts and resulted in a regular open column grid in the low level commercial spaces.
Phase 2 of Westfield London is an extension to the existing shopping centre. Part of the works was to create a linking mall between the two phases. Substantial reworking of the existing structure was required including the partial demolition and re-support of a large concrete core. Walsh designed a complex steel frame, using 15,000 tonnes of steel to span the roads and central line infrastructure including heavy plate girders, trusses and hanging structures.
Currently under construction this building sets new benchmarks in purpose built student accommodation. The development features three towers, one of which stretches to 46 stories, and will be Europe’s largest student PassivHaus scheme. The building is situated under the flight path into London City Airport so there were strict constraints on height which Walsh facilitated by designing thin floor slabs. This reduced the height, minimised weight and helped reduce foundation costs.
Walsh leveraged the power of integrated geotechnical and structural engineering to approach the foundation design for Calders Wharf from a new angle, using our experience of building over other railway assets in London to value engineer the development. We proposed the use of a ‘compensated raft’ approach, constructing a sacrificial basement to offset the weight of the building. Net loadings and tunnel displacements were reduced to agreed limits through an extensive and detailed liaison process with the DLR.
This private rented sector (PRS) scheme consists of 482 homes, commercial and retail space and features 32 and 35 storey towers. NO6 and NO8 were built using innovative MMC techniques which were designed in partnership with Mace. This allowed whole floors to be built in just a few days. Walsh took a proactive approach the value engineering and identified several key savings across the development, the most significant of which was to change the piling and reduce the tower core sizes.
We are delighted to have been shortlisted in the Structural Awards 2023 for our work on 9 Millbank. 9 Millbank is a luxury residential led mixed-use development which was a hybrid refurbishment, reuse and rebuild project on a historical and complex site.
