Structural Beam Design for the home or office.

We can provide structural calculations for steel, timber and glu-lam beams and frame systems. Our engineers have a combined experience of over 50 years of structural engineering experience.

If you are looking to remodel your home or work space where a structural opening is required between two rooms, create an extension or new build property it is likely that you will need an engineer to assess the structural requirements . The trend at the moment is to remodel your home or commercial premises usually to an open plan layout. To do this often, you will require calculations to justify the removal of walls and replacement with a structural member. We provide a simple fast and cost-effective service, including a site visit with a price per beam costing. This allows you to easily budget the costs before our visit please contact the office on 01225 789307 to receive our full T&C’s and book in a visit.

Dropped Kerb Applications & Highways Planning Conditions

We provide drawings and applications for basic Civil Engineering works such as dropped kerb applications and planning highways conditions such as to alter access etc. New developments and many householders often seek to install a new vehicle access from the public highway. This usually involves installing lower kerbstones with the pavement reconstructed at a new gradient. Drop kerb applications include both the physical lowering of the kerb and permission to allow a vehicle to cross the public footway which otherwise an offence under common law. As the applicant the cost of applying and construction of the dropped kerb is usually paid for by you.


Why do I need to apply for a dropped kerb?

Because you do not own the pavement outside of your house and do not have the right to drive over it, additional dropped kerbs can be seen as increasing highway safety risks. Only a fully designed proposal for a new access should be put forward as it is estimated around 60% of all dropped kerb applications are rejected. Many of these are rejected because a client has chosen to make the application themselves without the services of an engineering consultant.

Soakaway Calculations to BRE 365, drainage strategy & Trial Pit Excavations

Percolation Tests/Soakaway Tests determine whether the ground is suitable for soakaways and sceptic tanks and are becoming increasingly common in planning application conditions. Western Building Consultants can provide an excavation and trial pit service to determine if using the natural strata can work to effectively drain the development.


How do Soakaways work?

Soakaways work by storing the immediate surface water run-off allowing natural dissipation and attenuation. Surface water has been historically disposed of through public sewers or watercourses. Due to flooding issues the government and local authorities such as BANES have discounted the traditional piped approach to draining sites and are replacing them with SUDS (Sustainable Urban Drainage Systems).

How do you calculate if the Soakaway will work?

To work out a soakaways size and suitability we need to carry out an onsite percolation test. A trial pit is excavated to represent the soakaway and the time taken for the water level to fall from 75% to 25% repeatedly is used to calculate the Soil Infiltration Rate (m/sec). Utilising this approach, we are then able to carry out an offsite Soakaway calculation demonstrating the type of Soakaway and size requirements.


If your development needs a soakaway design or any other of our engineering services, please get in contact with our Cardiff office on 02922679366 or email [email protected].

Applications to Welsh Water or other local Water Authorities to build over/near sewers

If you are carrying out an extension or new build property in Cardiff and wish to build over a sewer, you need to get a build over agreement. You may also require an application if you are planning to build footing near to an existing sewer. Welsh Water will not always allow you to build over a sewer so it is important that you employ a consultant such as Western Building Consultants to give you the best chance of engineering a solution that will be acceptable to your local water authority.

Whether you need an agreement to build near a sewer depends on a number of issues, such as depth of the sewer, the diameter/type of sewer and the number of properties it serves. It can sometimes be prudent to instruct us to carry out a consultation or instruct a CCTV survey of the drainage system prior to designing the project as it might not be possible to design an extension or house over the existing pipework.

As sewers are frequently located running along the back of houses, build over agreements are usually needed for extensions. In fact, we estimated that when the sewers for adoption regulations were introduced 90% of our householder projects required consent.

Sometimes it is not possible to build over a sewer and the drainage may need to be altered (called a sewer diversion). Sewer diversions are generally quite expensive and must be carried out by licensed contractors. The water authority will generally require the sewer to be tested on completion and a bond held for a period of time to rectify any issues with the new drain. Western Building Consultants have negotiated several of these types of diversion and produced the drainage drawings to accompany the request for diversion. These must be designed to an adoptable standard and it is important that a competent engineer is appointed to specify them.

If you need help with any of the aforementioned services, please contact Western Building Consultants on 02922679366 or email [email protected].

Cost Conscious, Value for Money & Fixed Fees

Cost Conscious, Value for Money & Fixed Fees

Whilst offering exceptional value for money we also bring a positive, approachable, pragmatic, realistic and well rounded attitude to your project. You will feel at ease discussing issues with your project, our pragmatic approach to design and refurbishment means that we can often deliver built in VALUE. One example of this is recognising where cost savings can be made in the design without compromising the overall scheme and offering a higher standard of technical specification over many of our competitors, this reduces the need for outside engineering input and ultimately saves you money in fees. We are grounded which means that we can deliver a build in a cost conscious manner in order to make sure our projects are buildable.

Well Networked with Local Knowledge

Well Networked with Local Knowledge

Where we do not have the in house skills to tackle an element of a project we are well networked locally to utilise outside consultants that we have built up relationships with over many years. You will get the best of local knowledge and be introduced to like minded trusted suppliers with excellent professional services.

One Stop Shop

One Stop Shop

We can provide the majority of services required for a small project in house, making us practically a one stop shop. Having most services in house means that we are often fully accountable for the professional services on your project, this ensures simplicity, communication and efficiency. By utilising a multi-disciplinary approach we are able to keep professional costs for the project extremely competitive and hassle free, essentially you only pay for one set of overheads.

Unparalleled Technical Knowledge

Unparalleled Technical Knowledge

We have unparalleled technical knowledge and produce comprehensive architectural designs and surveys. You will be getting market-leading technical advice that has been approached with imaginative problem-solving techniques. This helps us to identify potential problems with a build before they arise.

Our knowledge adds value, an example of this is that most architects do not provide any advice on the structure of a building during the building regulations approval stage, relying on a structural engineer to produce all work relating to the super structure. At Western Building Consultants we provide structural advice on many areas, such as timber design for floors and roofs, limiting the scope of the engineers work and saving you money.

Large Team of Surveyors

Large Team of Surveyors

Having a large team of surveyors means that your project is unlikely to be held up due to other circumstances, there will always be at least two surveyors familiar with the project therefore continuity and a personal service will be retained. On larger schemes a bigger team will be assembled with the required specialist knowledge to fully support your project.
