This article examines two related questions: 1. How does an engineer get paid for work done where there is no contract with the client? 2. Where a client invites tenders from various engineers for a particular project, does the client have any obligation to consider all tenders received? Ian R. Yule

The inelastic local buckling behaviour of cold-formed profiled steel sheets in the compression zone of a profiled composite beam is studied herein. The method considers a profiled composite beam in bending using a modflcation of the semi-analytical inelastic finite strip method. An inelastic constitutive relationship for cold-formed steel is used in the formulation of the clamped strip stiffness and stability matrices. A computer program incorporating material non-linearity has been developed that produces a new form of eigenvalue problem. A parametric study is undertaken for variables that influence the local buckling behaviour. Slenderness limits are derived that can be used for the rigid plastic design of cold-formed steel sheeting in profiled composite beams. B. Uy and Professor M.A. Bradford

This paper gives background information on the development of the NHBC Standard for building near trees - Chapter 4.2. It then reviews the recently published guidance, in Chapter 4.2 (1992), for heave precautions to foundations on shrinkable clay soils. Rev F.J. Atkins, R.W. Johnson and J.S. Barrett
