< Back Brett Aggregates - North Sea Terminal Europe's largest Radial Conveyor. Brett Aggregates are the UK’s largest independent building materials group, handling over 5m tonnes of aggregate and producing up to a million cubic metres of concrete every year. As part of their development plans to their Ready Mixed Concrete & Screed site in Cliffe , they required the design and fabrication of a new radial conveyor, the size of which would place it amongst the largest in Europe. SGL were appointed as the structural designer working in tandem with the fabricator Atherton Material Handling (AMH). A working concept was drawn up between parties which was then input into a Finite Element Model (FEM) by SGL. Our talented and experienced engineers drew upon their knowledge to optimise the concept design, bringing down material weight significantly from that of the first concept. A mixture of tension only cross bracing and compression/tension bracing was employed, along with a central triangular braced tower which allowed the 67m conveyor to cantilever approximately 23m. Detailed wind analysis was performed on the structure due to the dynamic nature of the conveyor being that it is not ordinarily fixed to a foundation. Various loading assessments were carried out to represent the dynamic loading patterns the structure will likely experience throughout its design life, ensuring safe and consistent performance under all foreseeable scenarios.

< Back Construction Supervision Rate £80/hr Contact Us Now About Construction Supervision services are provided to clients both large and small, whether they are domestic or commercial. We work with a number of commercial clients on multiple projects, acting as their subcontracted structural engineering expert to provide on site assistance to contractors during their works on a daily or weekly basis. Our aim is to directly assist with issues which arise during the prestart and construction phases so that these may be quickly and safely resolved with expert guidance to mitigate the risk of errors, project delays and associated unexpected costs. We are able to provide ad-hoc support in person on site or remotely via telephone, conference call or email. Typically we would complete a project from start to finish with an appointed Project Engineer. The appointed Project Engineer would also have access to an experienced team of in house design engineers to assist with any calculations, drawings or reports which may need to be generated.

< Back Structural Fire Design Rate £70/hr Contact Us Now About Fire design of structures ensures their safe predictable performance in the event of a foreseeable fire scenario. The level of fire design depends upon a number of factors and is often determined by carrying out a fire risk assessment. Typically, requirements are set out according to Eurocode with respect to time. Based on the requirements, a structural engineers first job is to determine the most suitable material and appropriate methods of fire protection to critical elements. The design is then undertaken according to the relevant parts of either EC2, 6 or 9. In the past, fire design was not always considered and this has resulted in terrible consequences such as the great fire of London in 1666 which resulted in the avoidable destruction of over 132,000 homes. More recently, examples of how serious the threat of fire can be to a building and its occupants are the Bradford City Stadium fire of 1985, the collapse of The World Trade Center Twin Towers in 2001 and Grenfell Tower in 2017.

< Back Seismic Engineering Rate £80/hr Contact Us Now About Seismic Engineering is not often thought of as immediately relevant within the UK construction industry. However, Britain typically sees an earthquake of magnitude 4 or above which is considered significant on the Richter Scale approximately once every four years or less. As such, structures of high importance and sensitivity may be required to meet the design requirements of Eurocode 8 “Design of Structures for Earthquake Resistance. General Rules, Seismic Actions and Rules for Buildings”. Such structures may include nuclear facilities, tunnels, bridges and sky scrapers to name a few. Seismic acceleration may be defined as the acceleration of the ground due to seismic activity, whereby the ground its self moves and accelerates. This movement can occur both laterally and vertically. The effects of bidirectional acceleration may also be additive as well as destructive. The effects of seismic acceleration can have devastating consequences to a structure which is not adequately designed to mitigate this. It can ultimately lead to complete collapse as was seen during the catastrophic events of the Christchurch Earthquake in 2011. Various methods exist to mitigate the risk of damage from a seismic event and it is the engineers responsibility to determine the most suitable system in combination with the clients requirements. Some examples are: Tuned Mass Dampers, Foundation Isolators, Plastic Hinges and Chevron Bracing as well as Hydraulic Dampers. Each one of these methods aims to mitigate the effects of seismic movement by nullifying the response of the structure, either via energy absorption through damping or altering the frequency response of the structure although these two methods are not mutually exclusive and are often used in combination to provide the most effective cost efficient solution. At SGL we are experienced in seismic design of structures both within and outside the UK. Our team are experienced designing on and offshore structures subject to seismic design loads. In addition to structures, SGL are also experienced in the seismic design of none structural items such as ME&P service support systems to ensure their safe and consistent operation during and following a seismic event in accordance with Section 4.3.5 of BS EN 1998-1:2004 +A1:2013.

< Back Structural Monitoring Rate £70/hr Contact Us Now About Structural Monitoring is provided in order to monitor a suspected defect within a property or structure to determine whether or not the defect is static or progressive. An example of monitoring would be where cracking has been found in a property which is believed to be due to subsidence of the foundations. Subsidence is the movement of soil beneath a foundation which causes the structure above to move unexpectedly; subsidence can occur for a number of reasons and can often be very serious although this is not always the case. For the engineer to determine whether or not subsidence is ongoing and therefore likely to be more of a serious problem, monitoring can be used. It is useful to know whether subsidence is likely historic or ongoing as it can have serious implications on the scope of any remedial works which may be necessary to stabilise a property. Similarly, monitoring can be used to assess the crack propagation in concrete or steel when subject to dynamic or fatigue loading conditions. This may be useful particularly on older structures where the material grades and susceptibility to defects are not known with certainty. Project Gallery Previous Next

< Back Lu's Place Cafe A New & Vibrant Venue Nestled in the Holme Valley. Lu’s Place is a new and vibrant venue located in the Holme Valley. SGL were appointed as the civil and structural designer for the project to develop a new multi-function venue on what was at the time a brown field site with a host of complex underlying challenges. Lu’s place its self forms one of three buildings on the site which were designed in house. The site is located on a hillside which had previously been levelled with made ground, with a steep embankment to the valley below. It was not possible to stabilise the ground by grading due to several trees on site with Tree Protection Orders (TPO’s). Various options of geotextile soil stabilisation were reviewed as well as soil nailing techniques and traditional retaining structures, although none were viable due to the complex site constraints. The solution came in the form of a ground beam inter-linked piled retaining wall which resulted in minimal environmental impact while providing stability to the site. Due to the challenging geotechnical conditions, ground beams & piles were used to form the foundations of the buildings. The superstructures were required to be two storey open plan buildings with the ability to be clad according to their clients’ needs with large uninterrupted openings for glazing, bifold doors and access. This design requirement was achieved by employing the use of efficient steelwork portal frames. Further geotechnical challenges existed in the form of contaminated land with VOC’s present. The risks of gaseous VOC contamination within the buildings was mitigated with the use of ventilation voids at foundation level, coupled with barrier membranes. These measures were coordinated with the Architect JG-D to ensure the visual appearance of the structures remained in keeping with the client’s expectations. Project Gallery Previous Next
