The Structural Engineer, Volume 74, Issue 5, 1996
It is becoming evident that a significant proportion of both public and private construction projects are adopting the design-and-build (D & B) construction procurement route. Whilst several advantages have been attributed to the D & B method, a number of disadvantages have also been ascribed to it. Concurrent engineering, an innovative product development paradigm that has emerged within the manufacturing industry, although popular within that sector, is still little known in the construction industry. However, the D & B method of construction procurement presents some similarities with the activities in manufacturing processes. This paper examines the traditional approach to product development as well as the concurrent engineering approach, showing its principles and goals, and its benefits over the traditional approach. It also discusses design function deployment, (DFD), a concurrent engineering design system, which provides a platform for the implementation of concurrent engineering. The paper concludes with the presentation of a new concurrent engineering model for D & B projects. N.F.O. Evbuomwan and C.J. Anumba
Following a brief description of the Kings Langley and Berkhamsted Bypass schemes, the design and analysis of the Ridgeway Footbridge is considered. Matters relating to the structural form, vibration and compression elements design are discussed, as are buildability and issues relating to the bearings at the springings. S.B. Willoughby
This excursus is in the form of a presentation made by Norman Jacobs, OBE, Chairman of the Football Licensing Authority, at the second seminar on 4 December 1995, which further discussed the report Temporary demountable structures, published by the Institution in October 1995. In my time, I have been, with varying degrees of success, a railway station porter, a street market trader, a soldier and a lawyer, but I have never been any sort of an engineer. Indeed, I rather suspect that I came by my invitation to participate here today not because of my past careers but more because of my present job as Chairman of the Football Licensing Authority, a body stemming from Lord Justice Taylor’s Report following the Hillsborough disaster in 1989. That report, with its 76 recommendations, is transforming the stadia where football is played and thereby the very face of our national game. Put in the context of what we are about today, I would suggest that those recommendations comprise a compendium of safety guidance which, within its immediate context and probably far beyond, will stand out as a reference point and safety landmark for years to come. Unfortunately, the trigger for that guidance was a disaster which claimed 96 lives, whilst the guidance document at the root of today’s seminar was prompted by the collapse, in 1992, of a demountable structure in Bastia, Corsica, causing 17 deaths and over 2000 injuries, followed in 1994 by the failure of another such structure at a pop concert at Earls Court involving 1100 spectators. All these cases highlighted the need for guidance. N. Jacobs
