Sub-contractors and Suppliers
11.1 Introduction
On any large construction project it is not uncommon for the majority of the works
to be performed by sub-contractors. Indeed it is not unheard of for all the works to
be sub-contracted by the main contractor. In turn, many sub-contractors will them-
selves engage sub-sub-contractors. he principles regarding the formation of a build-
ing contract, considered in Chapter 3, apply equally to sub-contracts. Similarly, many
of the issues considered in Chapters 4 and 5 will apply in a sub-contract situation.
This chapter will deal with the types of sub-contractor and the relationship between
employer, main contractor and sub-contractor, and finally will outline some of the
issues which frequently arise in practice.
