The job of the estimator is explained in detail at every key stage, from early cost studies, through the preparation of the estimate, to the creation of budgets for successful tenders. Each step is illustrated with examples and notes, and appropriate technical documentation.
Over recent years there have been significant developments in construction management, notably new procurement methods, greater emphasis on innovation and partnering, a greater reliance on cost planning as a methodology, and new developments in both industry and governmental reports and guidance.
This new and updated edition of a well-established textbook addresses each of these developments in turn, placing them firmly in the context of a thorough and easy to understand introduction to the roles of the estimator in preparing and winning tenders.
Practical approach to estimating from the contractor's point of view
Fully up-to-date with new procurement methods
Many examples of estimators' notes and documents

Commentary and worked examples to
EN 1993-1-5 "Plated structural elements"
The objective of this commentary is to present the scientific background to the rules. The mechanical models behind the rules are presented and references to source documents are given. All such models include simplifications, which have to be justified by calibration of the rules against test results. Several models for each failure mode have been checked with calibrations according to Annex D of EN 1990 and the ones included in EN 1993-1-5 are those giving the lowest scatter and the most uniform safety. The procedure for calibration will be summarised in section 1.2. It should be noted that EN 1993-1-5, being a generic code, does not suggest partial factor values. According to the Eurocode system these values depend on the specific application and should be given by application parts e.g. for buildings in EN 1993-1-1 and bridges in EN 1993-2.

Design rules for lateral torsional buckling of channel sections EC3 & DIN
(image edited)
info:
Channel sections are widely used in practice as beams. However, design rules for eccentrically loaded (not through shear centre) beams with channel cross-sections are not available in Eurocode 3. In this paper five proposed design rules are summarised, explained and their validity is checked by Finite Element analyses. The design rules yield ultimate loads that are compared to ultimate loads from geometrical and material nonlinear analyses of imperfect (GMNIA) beams with channel cross-sections. A parameter study is performed by varying the dimensions of the cross-section, the span length to section height ratio of the beams, the type of loading and the point of load application but is limited to load application through the web of the channels. Based on one of the proposed design rules, this study has led to a new design rule which conforms to Eurocode 3. This is a 10 pages article (a chapter).

Handbook of Thermal Analysis of Construction Materials
Info:
Authors: Vangipuram Seshachar Ramachandran, Ralph M. Paroli
Edition: Illustrated
Publisher: William Andrew, 2003
ISBN: 0815514875, 9780815514879
Length: 680 pages
Pdf: 6.57 Mb
This comprehensive book containing essential information on the applicability of thermal analysis techniques to evaluate inorganic and organic materials in construction technology should serve as a useful reference for the scientist, engineer, construction technologist, architect, manufacturer, and user of construction materials, standard-writing bodies, and analytical chemists. The material scientists at the National Research Council of Canada have established one of the best thermal analysis laboratories in the world. Various types of thermal analysis techniques have been applied successfully to the investigation of inorganic and organic construction materials. These studies have provided important information on the characterization of raw as well as finished materials, quality control, quantitative estimation, interrelationships between physical, chemical, mechanical, and durability characteristics. Information on the application of thermal analysis to construction materials is dispersed in literature and hence the IRC scientists embarked on producing a handbook, the first of its kind, incorporating the latest knowledge available in this field of activity. Almost all important construction materials have been included.
