Many factors such as unforeseeable events, managerial or financial problems of Contractor, insufficient technical capacity of Engineer&#039 / s site team and so on may lead to delays in construction projects. Proper analysis of compensability and quantum of a delay event is very important. Any delay analysis application can be considered as a result of the combination of contract documents, scheduler, record keeping mechanism at site, communication among project participants, delay analyst and delay analysis methodology. The main purpose of this study is to analyze the shortcomings frequently encountered in implementation of delay analysis applications and propose an integrated solution which synthesizes the solution methods for each. For this purpose seventeen (17) shortcomings were identified and solution methods were suggested for each. Moreover, these shortcomings were attributed to the previously identified elements of delay analysis applications such as contract documents, scheduler etc. Furthermore, an integrated approach is developed which synthesizes the suggested solution methods at different stages of delay analysis applications in order to obtain accurate and reliable results. In order to test the validity of the proposed integrated approach on a real project, a resource and cost loaded construction schedule with approximately four thousand (4000) activities is created by using Primavera software which is currently being used to monitor &quot / Construction of One Reception Center and One Removal Center Project in Erzurum&quot / . In the case study, the necessary events are created in order to be able to compare the results of the proposed integrated approach and the likely result of erroneous delay analysis applications. It was apparently figured out that the proposed integrated approach has yielded accurate and reliable results and a comparison table was prepared showing the difference between the results of the proposed integrated approach and the likely result of an erroneous application.

Les modèles du contrat FIDIC sont parmi les conditions de référence les plus couramment utilisées dans les projets internationaux. Le contrat FIDIC est calqué sur des conceptions juridiques enracinées dans le système de Common Law. Cependant, il y a une augmentation dans l’utilisation des modèles FIDIC dans les systèmes du code civil. Ainsi, les employeurs, les entrepreneurs, les organismes de financement internationaux, les ingénieurs, les avocats et les parties prenantes des projets, utilisant les modèles FIDIC dans les systèmes du code civil, doivent comprendre l'interprétation des dispositions FIDIC dans le contexte du droit civil. Dans cette recherche, l’application des provisions concernant le temps et le paiement supplémentaires sous l’auspice d’un contrat FIDIC (CONS) sera étudiée dans le contexte du droit civil, avec une attention particulière pour l’application spéciale de telles provisions sur le droit civil Egyptien. Les ressemblances et différences entre les provisions concernant le temps et le paiement supplémentaire sous l’auspice d’un contrat FIDIC (CONS) et le droit civil Egyptien seront identifiées. Des recommandations concernant les provisions concernées seront faites quant aux modifications à apporter soit au Code civil Egyptien soit au modèle FIDIC (CONS), selon le cas. Cette recherche vise à illuminer les employeurs, les ingénieurs et les entrepreneurs concluant des projets fondés sur le modèle FIDIC (CONS) et ayant élu le droit Egyptien en tant que loi applicable; gérer correctement les délais, retards et risques entraînant des paiements supplémentaires dans les contrats de construction. Cela devrait permettre de minimiser, autant que possible, les litiges associés aux retards et aux demandes de prorogation de délai et/ou du paiement supplémentaire. Étant donné que la plupart des systèmes juridiques du Moyen-Orient sont fondés sur les principes du droit civil et sont fortement influencés par le droit civil Egyptien, il est envisagé que cette recherche soutienne l'administration effective et efficace des contrats de construction dans la région. / The FIDIC forms of contract are one of the most commonly used standard conditions of contract in international projects. The FIDIC is based on legal concepts rooted in the Common Law system. However, there is an increase use of the FIDIC in Civil Law jurisdictions. Thus, employers, contractors, international financing organizations, engineers, lawyers and stakeholders of projects, using FIDIC in Civil Law jurisdictions, need to understand the interpretation of the FIDIC provisions against a Civil Law background. In this research, the application of time and additional payment provisions of the FIDIC (CONS) will be studied in the context of the Civil Law, with special application on the Egyptian Civil Law. Similarities and differences between the relevant provisions of time and additional payment under the FIDIC (CONS) and the Egyptian Civil Law will be recognised. Recommendations will be yielded as to amendments to be made either to the Egyptian Civil Code or to the FIDIC (CONS), as the case may be, in relation to the provisions at issue. It is envisaged that this research would help employers, engineers and contractors, entering into projects based on the FIDIC (CONS) and with the Egyptian Civil Law as the applicable law, properly manage time provisions, delays and risks leading to additional payment in the construction contracts. This should help minimize, as much as possible, disputes associated with and/or resulting from the delays and claims for extension of time and/or additional payment. Since most of the legal systems of the Middle East are founded upon Civil Law principles, and are most heavily influenced by the Egyptian Civil Law, it is envisaged that this research would support effective and efficient contract administration of construction projects among the region.

Delay and disruption (DD) to contractors’ progress, often resulting in time and cost overruns, are a major source of claims and disputes in the construction industry. At the heart of the matter in dispute is often the question of the extent of each contracting party’s responsibility for the delayed project completion and extra cost incurred. Various methodologies have been developed over the years as aids to answering this question. Whilst much has been written about DD, there is limited information on the extent of use of these methodologies in practice. The research reported in this thesis was initiated to investigate these issues in the UK, towards developing a framework for improving DD analysis. The methodology adopted in undertaking this research was the mixed method approach involving first, a detailed review of the relevant literature, followed by an industry-wide survey on the use of these methodologies and associated problems. Following this, interviews were conducted to investigate the identified problems in more depth. The data collected were analysed, with the aid of SPSS and Excel, using a variety of statistical methods including descriptive statistics analysis, relative index analysis, Kendall’s concordance and factor analysis. The key finding was that DD analysis methodologies reported in the literature as having major weaknesses are the most widely used in practice mainly due to deficiencies in programming and record keeping practice. To facilitate the use of more reliable methodologies, which ensure more successful claims resolution with fewer chances of disputes, a framework has been developed comprising of: (i) best practice recommendations for promoting better record-keeping and programming practice and; (ii) a model for assisting analysts in their selection of appropriate delay analysis methodology for any claims situation. This model was validated by means of experts’ review via a survey and the findings obtained suggest that the model is valuable and suitable for use in practice. Finally, areas for further research were identified.
