Mr M. K. Hurst (M) I was very interested to read of the application of post-tensioned slabs to a major building in the UK, never having really understood why the method has lacked popularity there. It is a routine form of construction in Australia, the USA, the Far East, and South Africa, where its economy has been recognised for many years. I have just completed the design of a building in Botswana, using slab post-tensioning technology from South Africa. In that building the slab was 200 mm thick with a column spacing of 6.3 m in each direction. This was a cheaper solution than the alternative in reinforced concrete.
Disputes in the construction industry abound, and there are a number of procedures to resolve them as an alternative to arbitration and litigation. The best known form of alternative dispute resolution (ADR) is mediation which is attracting interest as a real alternative to more traditional methods. It has been widely used since the early 1980s in the USA where it originated. It involves using a third party as mediator, acceptable to the disputants between whom mutual understanding to resolve the dispute is not possible. A. Jawad
Structural engineers appointed as the engineer on civil engineering contracts have sought to maintain a fair and independent approach to differences that arise on site. The quasi-arbitral duties called for in those contracts can no longer be performed. In order to ensure the early resolution of disputes and thereby save the parties‘ costs, it is essential to introduce a form of mediation that provides for the regular intervention of neutral persons to assist in the resolution of disputes during the course of the works. Three processes are advocated - a board of three members for large and complex projects; an advisor for the less complex; and a mediator on call where retention throughout the works is not justified by the cost. The procedures are incorporated into the contract conditions, and the board or individuals are appointed at the outset of the contract. K. Severn and P.L. Campbell
