Dining Extension, Manor School York

A new-build 2-storey infill to a circular internal courtyard within an existing secondary school building.  The new build comprised a steel frame with the roof designed to support plant. The intricate steelwork design around a supported hub and spoke arrangement meant the steelwork member lengths could be reduced for transport through the school to the site. 

3D Modelling of the existing structure was undertaken as part of the structural alterations, and the use of Revit software helped with coordination with the Design Team. 

Ampleforth Monastery

This £4m refurbishment of the existing Monastery has involved significant internal reconfiguration to update and modernise the Monks living quarters. The structural work has including numerous new openings through the historic walls, repairs to the stonework, roof repairs and the provision of a new footbridge. The works were completed in May 2019.

We have also undertaken several other projects at Ampleforth College including repair work to Ampleforth Abbey Church, repairs to historic ceilings and an inspection of the masonry arched bridge crossing the adjacent highway.  

Pascal Building, St Peter’s School, York


The new 2/3 storey, £3m, building provides new teaching spaces for the Maths and Modern Foreign Languages departments. The works involved demolition of existing buildings and the construction of a new steel framed structure supported on shallow concrete foundations. The lower ground floor teaching and plantroom areas are susceptible to flooding in extreme conditions and are detailed accordingly. This was our first project for the School, but more have followed. 

The building won the York Design Award in the Large Community (over £500k) category at the Awards ceremony at York University on the 24th June 2019.

New Boathouse, St Peter’s School

The existing school boathouse is close to the riverbank (where else!) but it regularly floods when the River Ouse is high and during the last major flood many of the boats were damaged. 

The new boathouse provides a larger space with an elevated floor level to ensure that only a major flood will affect the building. The new steel framed structure is however still built on the flood plain, so we have designed a “wash through” void below the floor slab to maintain the flood storage volumes. 

 The new structure is supported on piled foundation driven through the alluvial river deposits into the underlying gravels and clays.

Clarges, Piccadilly, London

The Clarges development in London overlooks St James Park and provide luxury apartments over 8 floors and across four distinct buildings. The bespoke external concrete cladding comprises fluted column section and interlocking spandrels.  
Our role was to undertake the structural design of concrete units for both temporary and permanent loads and included the design of steel bracketry fixed to the main structural frame to laterally restrain the panels.
 
Other recently completed projects include; 
  • The Molecular Sciences Research Hub at Imperial College, London. 
  • The Westgate Retail development in Oxford.
  • Building D1/D2 at the Wood Wharf development in Canary Wharf.
  • The Biochemistry Building at Oxford University.

Clifton Dining Room, St Peter’s School

The new building provides a kitchen and dining hall for Clifton Primary School. The main dining space is formed with steel “scissor tied” trusses and a glazed façade. 3D modelling of the space, using Revit, allowed early visualisation of the structure and coordination of the services for the heavily serviced kitchen roof space. The building has been in use for a full term now and is proving a big hit with Parents, Staff and Children alike. Recently we have completed an associated project to extend the playground and sports facilities for the School and provide an outdoor structure to provide solar shading and a framework for planting.

Hull Hospitals – Modular Wards

Like all Healthcare Trust’s Hull and East Yorkshire Hospitals are hungry for space and they  have responded to this need by providing numerous new clinical spaces within modular buildings. Not too glamorous for the structural engineer, you might think, but in one instance a new ward was provided at roof level on an existing 4 storey 1960’s block. This involved investigation and assessment of the existing concrete frame and foundations not to mention a huge mobile crane to install modular units onto a bespoke grillage of steelwork, to transfer the vertical loadings back to the original concrete columns.  

Another project to provide modular units at first floor level on an elevated steel frame seemed easier by comparison although the steelwork spans were not insignificant.

Hull Hospitals – Extensions to the ED

This phased project involved alterations to the existing 1960’s building, a couple of new extensions and provision of the, often quite complicated, pendent support structures. The project was completed in a number of phases over the course of a few years. Inevitably we have also undertaken a number of other smaller surveys and schemes for the Trust, everything from a simple opening through a wall to a local reconfiguration of the site roads. The finishing touch to the ED Entrance was a new lobby and external canopy.



Whitwell Grange

This project is further phase of development for a former Client on their rural site close to Castle Howard, north of York. The current phase involves the demolition of an existing barn and the construction of a new build replica, which neatly incorporates an extra floor, providing much needed office space. The new, two storey, tied steel portal frame has been clad in natural stone with the fenestration arrangement and masonry details replicated from the original barn.

The project was modelled in REVIT and coordinated via IFC exchange with the Architects ArchiCAD models.

New Dwelling, York

This new house will occupy a prime riverside site close to the centre of York. This challenging site has a mix of constraints, not least a flood defence wall, passing through it. We have led the negotiations with the Environment Agency to gain approval to increase the height of the flood wall whilst also coordinating the new piled foundations and the steel-framed superstructure which straddle the flood wall. This is another project where our REVIT modelling has been invaluable and has allowed the structure to be fully coordinated with the Architects ArchiCAD model. We hope to see our Client enjoying the riverside views later in 2020.

CT Scanners, Harrogate Hospitals

A new Client for us in 2019 but so far, we are looking at 6 new schemes ranging in value from £0.5m to £3.5m. The projects involve department alterations, courtyard infills and updates of equipment with a mix of new buildings and internal reconfigurations. It’s great to be in the investigations stage again, familiarising ourselves with the existing buildings which, typical for a hospital site, have been extended and altered many times already. Great to be working with a new Client team and with Gilling Dod Architects and DKP on the QS side.

New Tottenham Hotspur Stadium

We provided specialist advice to Buro Happold for the design of post-tensioned structures on the new, award winning, Tottenham Hotspur stadium in London. We assisted in the scheme design of the PT floor and advised on key details, slab thicknesses, joint locations, constructional issues and interfaces with the steel structures and contributed to the performance specification for the PT design works. We then assisted in the assessment and review of the specialist contractors design submissions. We have now completed a number of similar commissions and have significant expertise in using finite element analysis to model complex structural arrangements.

The Stadium won The Supreme Award for Structural Engineering in the IStructE Structural Awards 2019.

New Entrance Building – Hull Royal Infirmary

The project at Hull Royal Infirmary comprises construction of a new 3 storey extension to the front of the main tower block, and relocation of the paediatric unit to the second floor of the tower block. The new extension will provide a new entrance to improve patient flow, retail space, a chapel, restaurant and public areas. The upper floor will include parent’s accommodation, scope wash facilities and plant space. 

TrubyStevenson has provided Civil and Structural Engineering services, using Revit 3D modelling software to enable close collaboration with Race Cottam Architects, and Mott Macdonald M&E Engineers. The structure has a steel frame construction with long-span floors over the public open spaces and raking columns to the façade.

New Apartments, Scarborough

We have provided the structural engineering services on this new build residential project in the centre of Scarborough. The accommodation comprises 10 self-contained apartments over three levels. The structure comprises a steel frame built of a concrete raft foundation and incorporates parking structures within the footprint of the building. Work commenced in late 2019 and will complete in 2020.

Elephant Road, London

A high-rise residential development near Elephant and Castle London provides luxury apartments over 16 floors and across four distinct buildings. The bespoke external concrete cladding comprises punched window panel which are formed off-site, complete with the fully glazed windows.

Our role was to undertake the structural design of concrete units for both temporary and permanent loads and included the design of steel bracketry, fixed to the main structural frame, to vertically support and laterally restrain the panels.

New Critical Care Unit, Barnsley Hospital

Part refurbishment of the ground floor of the original multi-storey building, and a new-build extension within an internal courtyard to form a new CCU Department at Barnsley Hospital. 

The new build comprised a steel frame with a concrete roof to support plant. Modelling and analysis of the surrounding existing structure was undertaken as part of the alterations and to allow for new equipment. 
The site had many restrictions including challenges with access, and also difficult ground conditions due to adjacent basements. 

The use of Revit software helped with coordination with the Design Team.

Other current projects include:


  • Refurbishment of School buildings in Northallerton
  • Alterations and refurbishment to form Veterinary Care facilities
  • Expert Assessment of Post-tensioned transfer structures
  • Residential alterations and extension to private dwellings
  • Alterations to the Renal Ward at Bradford Royal Infirmary
