The construction industry is considered one of the largest industries in the world and in Syria, and one of the fastest growing, most costly and most complex industries due to the multiplicity of parties involved in it, its abundance, the different specializations, and the divergence and multiplicity of the objectives of its participants. Engineering projects are characterized by a special and unique nature, which includes their large time span, high cost, and the large number of contract clauses. In addition to the change in the requirements of the owner during the implementation phase and his request for additional works, as well as errors in the preliminary study submitted or its lack, in addition to the fact that it is an industry that takes place on the work site and not in factories, which results in its being affected by the site conditions and climatic conditions. The previous factors and others lead to the emergence of claims between the parties involved in the contract in order to maintain the profitability of the project and compensate for the damage caused. This research defines the contractor's claims accurately and presents their causes, types and classifications. This study presents a simplified model for managing contractor claims in construction projects in general. In particular, it focuses and elaborates on two of the main points in claims management, namely: The first point: the method of submitting claims within the binding time limits, accompanied by the necessary documents that prove the occurrence of the incident, the subject of the claim, and the contractual bases on which the claim is based. The second point: the financial and temporal analysis of the claims, detailing the analysis methodology to be adopted, explaining the analysis methods, and how to choose the appropriate method according to the nature of the project, documents, time programs, and available reports. It also presents a questionnaire study of a random sample of workers in the construction industry in Syria to indicate the extent of their knowledge of claims and their awareness of their causes, types and sources of origin. This research presented an integrated model for a contractor submitting two claims, one of which is temporal and financial, and the other is temporal only, to the owner through supervision, for a private sector project in Syria. The procedures followed in submitting were monitored and then the method of dealing with these claims was evaluated, pointing out the defects, errors and weaknesses in the contractor's handling of claims, and suggesting the best method for submitting claims later and in accordance with theoretical references. This study presented a number of recommendations that, if adopted and adopted, help to overcome the difficulties and obstacles that impede the correct application and make the best use of claims in projects. Recommendations are made to legislators to amend the laws governing contracts in Syria to keep pace with the development taking place in the world in the event that they are adopted, which will reflect positively on the construction industry in terms of quality, cost and time, and on the demand of qualified contractors to apply for public sector tenders.

The research includes an analytical study using the finite element method for the reinforced concrete beams containing holes in the body. These tested trophies have a rectangular cross-section and without additional armament in the area of the hole, and two patterns (patterned and simple support) were studied. As for the holes, they are rectangular in shape with variable dimensions, where prizes with one hole and prizes with two holes were chosen.
