V.4Appendix 4.17.1 - p.lAmendments No. V-2/85 (July)IntroductionTHE ADVISORY COMMITTEE ON THE APPEARANCE OFBRIDGES AND ASSOCIATED STRUCTURES(Reproduced from LWB Technical Circular No. 7/84)1.1 The appearance of bridges and associated structuresfrom time to time arouses public criticism.1.2 Most designers under normal circumstances produceorderly and disciplined designs that are at leastunobtrusive and inoffensive. Occasionally, usually asthe result of inexperience leading a designer toconsider the engineering aspects of his design to theexclusion of its finished appearance, an ugly orobtrusive bridge is produced. This is often becausethe design has not been considered critically from thepoint of view of appearance at an early enough stage.1.3 The Advisory Committee on the Appearance of Bridges andAssociated Structures (ACABAS) has been set up with thepurpose of ensuring that such designs do not escapecritical examination until too late.1.4 The existence of ACABAS is expected to increase theimportance of final appearance as a criterion fordesign, and is intended also to stimulate interest inthe appearance of bridges.Scope of ACABAS2.1 The activities of ACABAS are intended to be directedprimarily towards bridges and other structuresassociated with the public highway system. The adviceof ACABAS may, however, be sought on any bridge orassociated structure which will be exposed to thepublic view.
