Key Stage Visits

Early in the development the visit is best undertaken with the various trade supervisors so that any defects identified can be discussed to improve their understanding and knowledge.  

It also allows the supervisors time to discuss aspects of construction where the defect has occurred due to the impact that the work carried out by another trade has had on the following trades.  The sequencing or method of work can then be changed to the advantage of both trades.

Cavity barrier

Checks on cavity fire barriers can be undertaken to ensure that they are under compression so that the fire cannot by-pass them.  Often the cavity barrier may be in place but the continuity of the cavity barrier is broken allowing the fire to pass through it.  Done early these checks allow any issues to be highlighted and corrected.

Later in the development periodic visits would normally be carried out without the trades being present as it is a check to ensure that any lessons learnt at the beginning of the development have been addressed.  It is helpful if the periodic visit  

The stage visits highlight carrying out monthly visits work may be in progress so a judgement is made if a defect is likely to occur.  


When carrying out a key stage visit, work should be complete by all trades to a specific point. The work should be snagged by the trade supervisor and accepted by the site management. This allows an accurate reflection of any defects to be documented.

If possible, 2 or 3 plots should be viewed as different teams of the same trade may have carried out the work on the plot.  Often plots are of different configurations or locations such as being on the top floor or actual n the roof space.  There is then the potential for different defects to arise.


Where time allows other work can be viewed that is being undertaken.

Unless otherwise requested, the visit would take around 3 hours and the draft report would be with you within 6 hours and the detailed report within 72 hours.


The visit would consist of advising where compliance with the Building Regulations and NHBC Standards are not met for that stage of work.  If a different remit is provided, details such as drawings, specification and material details to assist with the accuracy of the report, would need to be sent a week before the visit.  Please contact us for more details
