How should pipes in trenches be described?

The EduTech Q&A

There are two methods to measure service pipes in trenches:

Method A - earthworks to be measured in the earthworks trade

Method B - reads in the Standard System as follows:

Pipe trenches (method “B”)

Where expedient pipe trenches may be included in the descriptions of the pipe or group of pipes and separated into successive total depths in increments of 1m, in which case descriptions shal

l include excavation, bedding, backfilling and compaction and disposal of surplus material

Excavations in material of a more difficult character shall be suitably classified and given in cubic meters as extra over, in which case the width of the excavations shall be determined as described in method "A"

In the model bills there are only 2 items:

1.  ?mm Pipes laid in trenches (trenches elsewhere)

2.  ?mm Pipes laid in and including trenches not exceeding 1m deep

Is it required to mention all the items included, as specified above, in the description in the BOQ or will the item in the Model Bill as item 2 above be good enough?
