Informal Discussion * o the Engineering Management Group f Site cost control Introduced by M. G. Paterson, B.Sc., A.M.I.C.E. Senior Civil Engineer Sir Robert McAlpine & Sons Ltd Reported by S . Erskine-Murray, BSc., A.M.I.C.E. In his Introductory Note, Mr Paterson pointed out thechange inspeed of construction from the relatively slow operations of the past to the need for maximum utilization of plant and labour in order to complete construction in much shorter times than previously had been considered either practical or economic...

Proc. h t n Cio. Engrs, Part 1, 1977.62, NOV.,623-642 Construction finance and cost escalation The various financial aspectsof construction work are described in relation to project evaluation and contract finance. The problems arising from cost escalation are shown to undermine the validityofsome traditionalandcurrentprocedures.Simulation techniques are used to quantify and support the analysis. After a brief analysis of the scale of inflation and the associated problems, first part the Paperthe most comin the of monly used financial criteria for project appraisal are described and their application is demonstrated...

Bridge management policy using cost analysis J. de Brito,MASc, PhD, and F. A . Branco, MASc, PhD, Agr Structural deterioration and lackof functionality have led to important investments in bridgerehabilitation in past years. Bridge management systems that initially presented only technical activities are now developing decision criteria to help the rationalization of decisions for bridge maintenance and rehabilitation. This Paper presents a global cost analysis for use as a decision criterion within a bridge management system. It makes it possible to calculate all the costs of a bridge, fromits design to itsdemolition/replacement, including the functional costs and the benefits associated with its service life...

7460 Cost optimization of pipe sewerage systems The Paper describes a method of writing factors considered in sewerage design of cost (dig plus pipe), gradient, length and cost function is developed, which is used mathematical expressions for the various foul water networks. The four factors are loading, and cost and loading. A general to minimize overall network costs. Notation cost factor for pipe ij diameter of pipe ij minimum allowed trench depth at node average trench depth between nodes i and j friction factor in Darcy's equation acceleration due to gravity frictional head loss along pipe associated head at node ground elevation at node length of pipe ij hydraulic gradient between nodes i and j total load of nodes in square i flow velocity along pipe average load of nodes i and j equivalent pipe surface roughness square B in grid reference system Introduction At present, the solution to many design problems involves the repeated application of analysis to slightly modified networks...

Proc. Instn Cio. Engrs, Part 1, 1984,76, Aug., 822-825 INFORMALDISCUSSION STRUCTURAL ENGINEERING GROUP Whole life cost of construction Introducers T. HUGHES, FRICS* C. J. F. P. JONES, PhD, BSc, MSc, FICEt Reporter C. Chenery, BSc, MICE, MIWEf Environmental costs and those charges associated with in-service construcuse of tion projects were seldom adequately totalled with initial capital expenditure to derive an overall monetary commitment, because designers and clients failed to appreciate their significance. The whole life cost of construction in a conventional sense, Dr Jones suggested, should include such factors as initial construction cost, operating, maintenance and repair charges and an allowance for demolition, but the perceptionof these costswas often a matter ofjudgement...

Proc. Instn Civ. Engrs, Part 1, 1978, 64, May, 347-351 8064 DISCUSSION Construction finance and cost escalation J. G. PERRY & P A. THOMPSON . Dr N. M. L. Barnes, Martin Barnes and Partners I should like to offer some comments on the section of the Paper dealing with contract price adjustment formulae. The Authors conclude that no non-adjustable element should be used. 67. When the Baxter and Osborne formulae were introduced it was suggested that the non-adjustable element (then 15%) was intended to leave contractors carrying a reduced but significant part of the inflation risk...
