About Structural Engineers

What is the role of a structural engineer?​
Structural engineers support you in the evaluation or design of your residential or commercial building project. 
Is a structural engineer the same as an architect?
Whilst an architect focuses mainly on the design, look and layout of a property; a structural engineer performs design checks, using structural tools, to ensure that the proposed works are structurally sound. 
Do I also need an architect?
​If you are planning an extension, loft conversion, full internal remodelling or a new build then you will need to hire an architect. If your project is limited to removal of one or a few walls within your property then you may only need a structural engineer.
Who submits the building control application?
​Usually this is done by the architect.
Do I need Planning permission?
​We would recommend you seek the advice of your local council.
What is a structural survey?
​Structural surveys, also known as structural inspections, assess structural defects and the general condition of a building or structure. A structural consultant might be looking at the feasibility of proposed alterations and extensions or perhaps undertaking an inspection for insurance purposes following a fire, flood or building collapse. Structural engineers also give advice on works needed to comply with Building Regulations. 
​
Structural inspections and surveys are normally limited to structural elements only i.e. we do not cover electrics, plumbing, fixtures and fittings, or finishes. Unfortunately, Essex Structural Engineers does not offer Structural Home Surveys for pre-purchasing a property.

Do I need a structural engineer for my home project?
If you are planning to make internal alterations, such as knocking down a chimney breast or a wall, or you’re planning to add an extension, you will need to hire a structural engineer.

If you are changing the structure of a building in any way, you will need a structural engineer. Doing so, without proper structural calculations, could be catastrophic. If you are making changes to load-bearing walls or removing chimney breasts you will need accurate beam calculations to ensure the structural integrity of your building. This also applies to changes to floors, roofs or foundations. Our role is to ensure that the structure and foundation of your building continues to be structurally sound.
​
Whenever a new build is being planned, you’ll need to hire the services of a structural engineer.
How much does a structural engineer cost?
​Fees for structural engineers are calculated on a time basis. It depends upon the complexity of the project and how much time is required to create drawings, calculations and reports, as well as visiting the property. We can usually advise you the full cost of our structural engineering services in advance.
What is a Party Wall Agreement?
Your building works may fall under the Party Wall Act 1996. We would recommend that you speak to a party wall surveyor, if you are:
  • building a wall up to or across the boundary with a neighbouring property
  • undertaking work to an existing wall
  • excavating near a neighbouring building
When should we start talking to builders?
​Our advice is to wait until planning permission is achieved and then develop the drawings in more detail in terms of construction and specification. Once these construction drawings are finalised, you are then in a better position to get accurate quotes from a builder.
When is the best time to send drawings to builders for costing?
​The best time would be once the final drawings are produced for building regulations and construction purposes. By waiting until this stage, the builders can quote by referring to the information from the drawings and provide you with an accurate cost for the works. The builder will also be in a better position to determine how long the build will take (start and finish dates) and offer contract and payment terms based on the information to hand, once they have a clear idea of what the project entails.

Are you insured?
​If the works are carried out in accordance with our drawings and specifications, all of our design work is covered by our Professional Indemnity Insurance. Please note that if your builder doesn’t carry out the work in accordance with our drawings, we will not be responsible.
Do you produce safe designs, accurate drawings and calculations?
Yes, each design is tailor made to meet your project’s requirements. Our drawings and structural calculations are based upon information gathered following a site inspection. We take into account building regulations and Construction, Design and Management Regulations. All of our engineers take health and safety responsibilities very seriously.
Do you provide architectural design services?
No, we do not provide architectural design services, but we are happy to recommend an architectural firm, if required.
Do you answer building control queries?
​
​Yes, we answer building control queries as part of our fee. We have 100% building regulations approval.

The Process

What are the next steps after I employ a structural engineer?
​A site inspection will take place first. We will then speak with you and your architect to finalise the project brief and then supply you with a full design package. Once this is signed off construction can begin. Our structural engineers will provide support through to project completion. 
Will you carry out a site visit for my project?
​Yes, unless notified otherwise. It is good practice to carry out a site inspection and collect as much information as possible about the project to provide the best possible design solution. It also helps avoid any unknowns that could lead to costly amendments further down the line.
​How long will it take to get my report, drawings or calculations?
​As a guide, we aim to issue structural reports within 5 working days following an inspection. For home alterations and simple commercial projects, we normally issue drawings and calculations within 10-15 days following your instruction and receipt of your architectural drawings. We can notify you of our turnaround times when you speak with us.
What happens once the structural calculations have been completed?
Simple – you and your architect or builder will present the structural calculations to the designated Building Control Authorities for approval.
When can building work start?
​You can start building as soon as you have the complete design package, planning permission, party wall agreement (if applicable), freeholder consent (if applicable), finance, building control. Please check with your local authority as to whether other requirements are needed.
Can we alter the drawings whilst construction is in progress?
​If you require any amendments to the drawings, please contact us immediately. This could impact the structural integrity of the building. Additional fees to resolve the changes may incur.
