Structural Surveys and Reports

We offer a range of surveys and reports to meet your project’s requirements. See below to find out more about the main services we can provide.

What does our package include?

Structural surveys are undertaken in order to report on structural defects such as cracks in walls, damage caused by water or subsidence / movement of foundations etc. The initial report will usually be based on a visual inspection of the associated area of concern. If further intrusive investigations are required to identify the cause and condition of the defect/s, we will also advise on this.

Our packages include the following, but not limited to:-

  • Site inspection, usually a visual survey unless dictated otherwise.
  • Verbal advice and discussion during the visit.
  • Written report by a chartered or near chartered engineer.
  • Email and phone support for queries related to the technical report.

Additional items:-

  • Further inspections to view opening up works, if required.
  • Further inspections to sign off work undertaken (by request only).
  • Further supplementary reports.

Our reports usually include a description of the structural defects and the suspected causes, suggestions on how to remediate and estimated costs associated to fix (by request). We can also provide recommendations on further investigations if required, such as trial pits or CCTV surveys which may be required to conclude our findings.

Cracks in walls, ceilings and floors are caused by a number of different reasons. Depending on the size, exact location and frequency of the cracks, the risks associated can vary substantially. Hairline cracks to a new ceiling below a timber roof can often be caused by the thermal expansion and contraction of the timber over time, as its natural moisture content fluctuates and may have no significant structural concern. Whereas larger vertical cracking to a masonry gable wall can sometimes indicate movement of the walls below, or the pulling away of wall from insufficient tying of the structure. Cracks with ongoing movement may pose a larger risk than historical cracks that have settled and remain stationary.

Subsidence or movement of foundations can often cause cracking and structural damage to the building above. There are often a variety of causes for these movements and the investigation and remediation can vary based on the cause and associated risk. Washing away of fine particles in the soil or having foundations cast onto poor ground can lead to localised movements. Tree roots have a tendency to penetrate through weaknesses in foundations and can lead to ongoing problems if not dealt with effectively.

Selling property with known or visible structural defects can not only put off prospective buyers but also lead to requirements for structural surveys to be undertaken before mortgage lenders release their funds.

Building Survey Reports

Building surveys cover all aspects of the building fabric such as insulation, heating, electricity, gas, drainage etc, whereas a structural survey is limited to the structural elements of the building.

Our packages include the following, but not limited to:-

  • Site inspection, usually a visual survey unless dictated otherwise.
  • Verbal advice and discussion during the visit.
  • Written report by a chartered or near chartered engineer.
  • Email and phone support for queries related to the technical report.

Additional items

  • Further inspections to view opening up works, if required.
  • Further inspections to sign off work undertaken (by request only).
  • Further supplementary reports.

Basement Impact Assessment Reports

Many local authorities within Greater London and its suburbs require a basement impact assessment (BIA) report as part of the planning permission application. This is required to review the impacts on flooding, surrounding structures and the local geology to ensure any known risks are mitigated.

The geological strata typically found within London is of clay formation and is prone to seasonal shrink and swell leading to subsidence and heave. In exaggerated cases this can lead to movement of the foundations and ultimately the superstructure above. The specific ground conditions within the vicinity of the property should be taken into consideration to assess any potential issues during or after the construction of a new basement.

Another key area of the assessment report is to understand and record the proximity of the development to public footpaths and buildings. Any works undertaken must be fully hazard and risk assessed.

One of the most undesirable factors in the construction of a new basement is the presence of groundwater. Understanding the surrounding soil and water table is key to a successful project. If a high water table is present but is known in advance of the commencement of the construction, suitable measures can be put in place to control this from affecting the project and the surrounding area.

Full BIA requirements can vary between each local authority and between each particular project but usually includes the following:-

  • Site inspection visit to review requirements specific to project,
  • Description of Existing Structure,
  • Ground conditions/geology,
  • Research into British Geological Survey maps & borehole data in surrounding area,
  • Potential ground movements to adjoining properties,
  • Assessment of Party Wall Matters,
  • Temporary construction works and methodology,
  • Indicative programme of works,
  • Control of noise, dust and vibration statement,
  • Flood risk assessment,
  • Drainage review,
  • Trees impact review.

Method Statements

Depending on the scope of works and complexity of the project, method statements can be provided to outline the approach to construction management. Typically, method statements outline the proposed works and how they will be carried out to ensure that construction is carried out safely and efficiently with minimal adverse impacts. Throughout construction the method statement will be constantly reviewed and any changes or improvements will be re-submitted and approved by the relevant parties.

Method statements are required to review the associated hazards and risks when undertaking construction works. This is necessary for temporary works in order to avoid compromising the structural integrity of the building as well as the adjacent properties. Construction method statements may be required under the guidelines of the party wall notice or for submission to local authorities prior to permission being granted for the proposed works.

Items typically covered within a method statement include (but not limited to):-

  • Hazard and risk assessments with mitigation measures
  • Health and safety of workers, environment and public
  • Design philosophy review
  • Construction sequence
  • Temporary works methodology review

Feasibility Studies and Reports

Feasibility studies are carried out during the early stages of a project to assess its viability with regards to technical, economical, legal, operational and scheduling (TELOS) factors. This can be particularly important when renovating existing properties as the changes that are made should not jeopardize the structural integrity of the building.

When considering the condition of existing buildings, the five factors noted above should be taken into account. Firstly, if there are any significant structural defects it should be decided if the building should be demolished or repaired. Following this we can assess design requests such as the proposal to add or remove floors, walls or columns etc.

This will depend on many design factors and parameters and there is definitely no one set answer. For example a solution to reduce beam weight might be done by choosing two lighter beams instead of one beam or by changing architectural layout and inserting a column somewhere along the span of the beam or by changing the structural layout of the beams, etc. The options can be endless so best to discuss specific requirement with the project engineer with open mind that each project is different and solutions can vary from project to another.

If construction work is proposed in a project, involving altering the existing structure, adding significant loads or building a new structure, then you will need a structural engineer. If you are unsure whether the alterations are structural (such as whether a wall is load bearing or if removing a chimney has structural implications) then you will also need advice from a structural engineer.
