A wide ranging and up-to-date review of experience of tunnelling contracts, particularly those for sewerage and drainage tunnels.

In recognition of the importance of site investigation for ground engineering works, and

the need for site (ground) investigation specialists to be aware of the contractual

significance of their results and interpretations, the writer began work in the early 1980s

on two areas of the subject: first, a survey of UK tunnelling contracts and associated site

investigation costs, and, second, a review of the place of site investigation in tunnelling

contracts. The impetus for the work stemmed largely from the major tunnelling activity in

the north-east of England and particularly on the Tyneside Sewerage Scheme which is

now substantially completed. The former work was reported* and circulated to those

companies that had responded to the request for information, and was also made available

to other enquirers. A significant feature of the analyses was the manner in which all the

cost data on tunnelling contracts and their site investigations were recalculated to a

common base date, so allowing realistic conclusions to be drawn as to the cost

effectiveness of the investigations. Statistical packages were used to resolve trends

between geological, geotechnical, geometrical and cost data. Several earlier, quite short,

and unpublished versions of the latter review were produced as a private initiative and

circulated in a limited manner within the industry. The project was then put on the ‘back

burner’ until in late 1989 when, realising that many site investigations for tunnelling

works were being conducted without a firm understanding of the contractual problems

which could ensue, the writer decided to revise and considerably expand the text.
