Slim. elegant balcony design 9th January 2013

Happy New Year! We have recently completed the structural engineering design of a new build house, which in common with many of our projects had particular quirks in the design. The property is to be 2 storey, with a 'ship' style balcony wrapped around the gable and part side elevation. A large span glazed door opens through the gable end, beneath the balcony. The Client's requirement was to minimise the depth of the balcony floor plate but at the same time minimise the ... more...

Loft Conversion 26th October 2012

I have just completed the design of a loft conversion for a bungalow with traditional timber gang-nail fink trusses. A feature of gang-nail fink trusses are the slender sloping rafter and ceiling joist elements. As soon as the truss action is removed (the truss internals have to be removed so as to create habitable space) the sloping rafters and ceiling joists immediately become inadequate to support roof and floor/ceiling loads. New structure therefore has to be inserted in order to ensure... more...

Supermarket Extension 19th October 2012

Work is now well underway on phase 1 of a supermarket extension that we are involved with. Phase 1 comprises demolition of existing outbuildings and construction of a warehouse, whilst phases 2 and 3 will involve internal alterations to the existing shop floor and back of house? Sounds simple? Not so! The site is bounded on 3 sides by existing structures, some of which are retaining walls and are on the verge of instability. The new site levels mean that these structures will be undermine... more...

Investigations into Existing Basement Water Ingress 14th August 2012

We have been appointed to undertake intrusive investigations and load testing at a substantial domestic property in Suffolk. The existing structure includes a single storey basement, which suffers from extreme damp and water ingress, the source of which is not immediately apparent. Our investigations have determined the source of the water ingress and provided recommendations for protecting the basement from further ingress. The existing ground floor slab (built over the basement) has suf... more...

Indoor Swimming Pool for Private Client 18th June 2012

We have recently completed the design and detail of a new swimming pool for a private Client in Suffolk. The swimming pool structure itself is formed as a reinforced concrete box, with hollow concrete blockwork acting as permanent shuttering. The roof, being similar to a saw tooth roof, has been designed as a combination of steelwork and timber, with restraint against roof spread being provided by cantilever buttresses and internal moment resisting frames, all elegantly detailed such that the ... more...

Structural Engineering Design at Holiday Park 11th May 2012

We have been appointed to provide structural engineering design services for a development at a holiday leisure park in Lincolnshire. The development will involve the construction of a new swimming pool, reception and shop. An existing steel portal framed 'grain shed' is to be re-used in the development, with strengthening measures designed as required. It is likely that there is a high water table on the site, meaning that anti-flotation measures will be required in the design ... more...

Design of Highway Retaining Wall 3rd May 2012

We have recently completed the design of a retaining wall, which is retaining public highway. The wall is located in the London Borough of Merton. The service we have provided has included the production of an AIP (Approval in Principal) document for design of the retaining wall, the approval of which has been obtained from the local Highway Authority. We have also designed the temporary works necessary to support the public highway whilst the permanent retaining wall is constructed, which ... more...

We are delighted to have been appointed to provide structural engineering advice in respect of a luxury penthouse refurbishment and roof top extension in the heart of London. The Developer is undertaking the work on an under-tenancy agreement to our Client. Our services require us to liaise closely with the Developer's project team in order to ensure that our Client's interests are safeguarded. The penthouse is located at the top of a 6 storey steel framed building that dates fr... more...

Conversion of Listed Barn 10th February 2012

We have recently completed the structural engineering design for a conversion of a listed timber framed barn which has required some intricate structural engineering and detailing. One of the principal challenges has been to provide support to new roof construction immediately above the existing roof (the timber rafters, ridge etc. of which are to be retained) without loading the existing roof. This has been achieved by the insertion of a 'slim' steel frame into the building, which... more...

Goodwood Festival of Speed 6th February 2012

John Cutlack of Capita Symonds visited the East Anglian branch of the Institution of Structural Engineers earlier this evening to deliver a presentation on the structural engineering involved with the enormous sculptures that are constructed every year for the Goodwood Festival of Speed. It was fascinating to hear the processes involved in arriving at the finished article, each sculpture being an exemplary case of structural engineering at its elegant best. Lotus are the sponsors for the... more...

Design of Tied Pyramid Roof 30th January 2012

On the face of it, a simple single storey domestic rear extension but complicated by a vaulted ceiling, a glazed gable on the end elevation and a hipped end at the junction with the existing building. Add to this the requirement to avoid unsightly (and expensive) steel framing then the challenge of preventing roof spread becomes significant. The challenge has been overcome by designing the roof as a 'tied pyramid', with a dormer on one face forming the new gable end elevation. The... more...

Structural Steelwork Design / Foundations in Root Protection Zones 16th December 2011

We have recently completed the design of structural steelwork framing for a large extension to a property overlooking Thorpe St Andrew in Norwich. The works involve partial demolition of the existing cut rafter roof and subsequent replacement with an extended vaulted roof. Utilising 3d modelling we have managed to design efficient steelwork framing that abuts the existing cut rafter roof but does not load it, meaning that the existing roof does not require strengthening to support the new cons... more...

Retro- Strengthened Floor Pit 15th November 2011

A project for which we did the structural engineering has just completed on site. The project was to strengthen an existing floor pit (5m x 3m x 3m deep) constructed in an industrial facility, such that it was able to support significant vertical and lateral loading from mechanical plant to be located within and above the pit. The design had to consider the implications of support to adjacent construction, also vibrations arising from operation of the mechanical equipment. The solution involv... more...

Institution of Structural Engineers 8th November 2011

John Nolan, the President elect of the Institution of Structural Engineers, was in Norfolk last night. He gave a presentation entitled 'Some Thoughts on Big Sheds', which was fascinating. Big sheds refers to distribution centres getting close to 1,000,000 square feet in area! I was also very honoured to receive the Chairman's medal, signifying that I take up the reigns (in December 2011) of Chairman of the East Anglian branch of the IStructE.... more...

Commercial Balustrade (for Art Gallery) 18th October 2011

We've just completed a design for a balustrade, to suit retail loadings. A key part of the design was proving the axial compression capacity of a combined steel and beech handrail, the steel element being a flat plate inserted and screwed into a rebate formed in the underside of the circular beech handrail. The screw fixings not only transfer compression but they also serve in helping to prevent buckling of the beech handrail.... more...
