ABSTRACT
The need to monitor progress for building projects is reviewed. It is then recognised that variations will occur during the course of the project. The nature of construction work therefore requires the form of contract to allow for these variations. A case study is presented for a project and types of variation classified. Interviews with the planning team research how variations are monitored during the construction stage. Models are then given for guidance to planning engineers when monitoring variations. Model one deals with contractually based variations and includes communication, information preparation and contractual requirements. Model two shows how to account for additions or reductions to programme activities. The calculation of activity durations are noted in relation to their component parts and work already completed. Following the recommendations gives a working method for planning and progressing variations to building project activities.
Le besoin de contrôler l’avancement des projects de construction est reeexamine. Il est alors accepte que des variations apparaitront au cours de la realisation du project. La nature des travaux de construction exige done une form de contrat appropriee qui prend en consideration de telles variations. Une etude de cas, concernant un projet et des types de variations classees, est presentee. Des entretiens avec l’equipe de programmation ont pour but d’examiner les procedures de controle de ces variations durant le processus de construction. Des modeles guides sont alors presentes aux techniciens des equipes de programmation pour les aider dans le controle des variations. Les recommandations proposees offrent une methode de travail dans le domaine de la programmation des variations et de l’avancement des activities du project de construction.
