< Back Civil Infrastructure We routinely carry out design and inspection works on civil infrastructure, supporting clients & principle designers. A key part of our business is providing civil infrastructure design to clients and supporting large infrastructure projects throughout the UK and beyond. Whether it be waterways, waste management facilities, bridges or transport installations we are skilled and able to assist with your project. Our in house team of experts are skilled in the design of steelwork and reinforced concrete, including modern techniques used to increase the performance of these materials such as through means of composite action, post tensioning and cable staying. We have a wealth of experience across our company which allows us to deliver on infrastructure projects, whether that be as the principle designer or as a subcontractor delivering part of the overall scheme. In recent years we have actively played a role in the design of elements of HS2 as well as improvements to St Pancras station and design works for Yorkshire Water waste water treatment plants as well as many more.

< 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 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 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 Earth Retaining Structures Rate £70/hr Contact Us Now About Earth retaining structures are engineered to retain soil & rock. They are typically used to accommodate changes in grade as well as to provide access or throughways and to buttress the toe of slopes. Many older walls may be constructed with the intention to retain earth, but without proper design these will almost always result in failure given enough time. Often, failure of an inadequately designed retaining wall will happen abruptly and sometimes with little warning which is why it is crucial to ensure a proper design is established. Retaining structures can take many forms depending on their intended purpose and finish required. Where a vertical drop is required to maximise space available on the lower level, a reinforced concrete retaining wall may be the best option. Conversely, where a slope is to form part of a wider landscape and may be visible, often gabion baskets or a geogrid structure may be preferable as these can often have a more natural visual appearance as well as being cheaper and potentially more sustainable. At SGL we are experienced in the design of all types of earth retaining structures and we would gladly provide our expert guidance in helping you determine which might be the best option for you.

< Back Building Service Supports Our building services team have worked on a large range of projects both large and small. We can provide a unique service including seismic and fire design of support systems as well as suspended equipment in nuclear facilities. SGL have supported hundreds of multi million pound Mechanical, Electrical & Plumbing (ME&P) installations across the UK and Europe over the last 20+ years. We specialise in providing fast turn around efficient service support designs to our clients. By engaging with the ME&P contractor early in the design process we are able to offer our guidance and expertise to influence the design and layout of the installations to ensure they are carried out in the most cost effective and efficient way. This proactive approach results in cost and time savings, as well as often resulting in a more simplistic design, thereby reducing the risk of unforeseen complications. We specialise in fire design of service supports as well as seismic design. Fire design often involves an element of testing to be carried out where light weight support systems such as Unistrut or similar are to be used. Seismic design is usually determined based on the performance requirements of the building as set out in the client specification in accordance with EC8. Typically, services are restrained from seismic loading by way of cable braced systems or rigid bracing; sometimes isolation & movement joints may also be used or required. Ground mounted equipment is often restrained by the use of “snubbers” or “bumpers” to limit movement of equipment. Previous Next
