Structural Engineer's Inspections And Investigations
Structural Inspection, Structural Safety Inspections, Structural Investigations Chartered Engineer's Reports throughout
North and West London
When estimating the fee for a structural inspection or structural investigation only limited information about the extent of investigation and reporting is known.  A concise structural inspection will generally be suitable for the purchase or sale of a property where a structural engineer's report has be requested by a surveyor.  To cater for more serious or extensive defects our fee rises in multiples of £40 with a cap agreed at the time an inspection is instructed.  The cap will depend on the nature and size of the property or structure and the known defects.  The cap will normally not be reached.  We have a flexible fee structure and are happy to discuss individual situations in order to limit or share the risk of the reporting cost as apprpropriate.

This white rot was found in the floor of a Victorian Church.  Decay had been developing slowly over a number of years but accelerated as a result of laying a carpet which prevented the natural ventilation through the floor boards, and an increase in the level of damp present in the atmosphere and stone foundations caused by blocked drains.  This floor had to be completely replaced and remaining spores killed.
This Victorian brick culvert runs beneath a private home.  The arched roof had become defective in three places.  Bricks had become overstressed during building work.  Joints had washed away from an exposed section due to percolation of rainwater onto the roof of the culvert and over the years the mortar was washed out leaving the bricks intact but loose and close to the point of failure.  The section in the picture had no supporting brickwork below the earth and could have failed at any time.
This defective brick arch lintel is in a Georgian town house.  The mortar joints in the brick arch have become overloaded and cracked as a result of excessive deflection of a timber wall plate carrying floor joists across the window head.  The lintel was not replaced but pinned to the brickwork over to become an integral part of a much larger arch.
Diagonal cracking in brickwork as seen here is typical of movement caused by subsidence.

 Concise Structural Engineer's Inspection
 Cracks in brickwork may be caused by one or more of a number of causes.  A vertical crack, especially close to a corner or junction may be the result of expansion followed by shrinking that results from thermal movement caused by the suns heat and winter chill.

This Georgian farmhouse had been empty for twelve years and was unsafe and derelict.  Subsidence coupled with construction flaws had resulted in structural movement of the rear wing causing the roof to collapse and water to penetrate and rot the timbers.  Following the inspection strategies were developed to fully restore the house as a modern home.



This crows foot support at the base of hip rafters is typical of traditional roof construction.  If water penetrates through the roof covering due to the weight of the roof causing the eaves to spread outwards then rot can set in.  Thisd will often be accompanied by masonry cracks and slippage of bricks.  This example was found during a structural inspection of a Georgian town house in Central London. 



Victorian construction flourished with the ability to mass produce ornamental features formed in moulds.  What may appear to be solid stone may in fact be a hollow moulding supported by a cast iron frame.  If cracks form in the outer case then the cast iron will deteriorate and expand as rust develops forcing off part of the casing.  This example was found during a structural inspection of a building that started out as an Edwardian dining club in central London.


The concise structural inspection consists of three main elements
The first element
A chartered engineer will make a general assessment of the whole property with regard to age, construction materials and overall condition. 
The second element
A detailed visual examination of the known defects - in particular cracks in brickwork, leaking roofs, damp or rotting timber.  At this time, if ground movement or subsidence is suspected we will assess the proximity and possible influence of significant trees and drains. 
The third element
The final part of the inspection is that of checking for the presence of structural movement or cracks in brickwork that may not have been previously noticed but are often associated with the observed defects. 
The report
A concise report will be prepared to record the observations, appraise the structural condition, and recommend essential and urgent action.  In addition recommendations are included with regard to time scales and importance of less urgent work.

Structural Engineer's Safety Inspection


We carry out Structural Safety Inspections either to assure the ongoing safe operation of safety barriers, escape stairs etc.  We may also advise on emergency or planned action where there is risk of injury from structures with known serious structural problems.

We will provide a certificate of safety signed by a chartered engineer that states any conditions that may need to be fulfilled and makes a recommendation for the frequency of future inspection.
Site Visit and Structural Engineer's Advice
There will be occasions when advice is needed before embarking on a project, or when something unexpected is found during works.  A report would be issued on completion as a record of the findings and recommendations.  The cost for this would normally be about £40.00 less than the cost for our concise inspection report.
Comprehensive Structural Engineer's Inspection
A comprehensive structural inspection is needed when structural repairs or strengthening are to be carried out in conjunction with structural refurbishment or alteration.
This type of inspection is concerned  with the strength and adaptability of the structural members and not just their condition.
This requires more observations and a much more detailed report that discusses the various options  that could be pursued and rules out those that are unlikely to be beneficial.

Structural Engineer's Investigations
Investigations consist of in depth searches for information not available by visual means. 
This may involve uncovering foundations or roof structure to examine hidden defects.  It may require floor boards to be lifted, plaster to be removed from walls and samples may be taken for laboratory testing to determine their condition or structural characteristics.
