with London Clay (and similarly overconsolidated clays) at shallow depths. Note that the sample disturbance
component is dependant on the method of sampling and any subsequent recompaction. The above plots show
this to be 100kPa which is the value suggested by the BRE on the basis of their limited number of tests on
recompacted samples. This may or may not be appropriate in this instance and judgement should be exercised.

Our assessment of the drainage system is based on our visual inspection and on
information collated at the time of the survey. Where assumptions have been made
these are based on our experience and do not constitute any form of guarantee, nor
do we guarantee that further deterioration will not occur following this survey.
CCTV video records will be stored for a period of 3 months from date of inspection
and then destroyed.

General Terms and Conditions
1
On site parking is a prerequisite of any drain repair contract. This quotation is to the addressee only and should not be
forwarded unless prior agreement is obtained from CET Structures Ltd. Every effort will be made to match existing surfaces
however, there will be evidence of excavation works in certain circumstances.
2
The rates do not include for excavation of surfaces other than soft ground or concrete < 100mm thick; reinstatement other
than concrete <100mm thick; internal excavations; reinstatement >750mm in width; excavation of depths greater than 1.2m;
reinforced concrete.
3
CET`s standard soakaway that is priced on the agreed alliance schedule of drainage rates is constructed to dimensions
specified in the NHBC Guidelines for small soakaways. The soakaway is generally located 5m from any foundations (should
site constraints permit) and is constructed to provide adequate short term surface water storage and percolation into
surrounding ground. This small 1m3 soakaway is usually of sufficient capacity to accommodate average rainfall from an
average surface area of roof space, however in extreme weather conditions and /or larger than average roof surface area
feeding the soakaway, surcharging may occur.Alternative designs and prices are available at a cost along with percolation
testing. Certain ground conditions may not be suitable for soakaway design due to low permeability and this information is
not always readily available.
Notes
For excavation and reinstatement of any steps, will be done on day work rate.
With a minimum of 4 hours. Materials at cost plus 25%.
Any obstacles, shubs & plants that are located in the working area will need to be
removed by others to allow for these works
The decking will need to be removed/replaced by others to allow for the works
No allowance has been made for the removal/replacement of the boundary fence
