Top priority to manage construction projects is given to the planning and scheduling in order to keep the project duration, which is one of the most important factors in construction management. However, recently most of public construction projects especially for civil projects are delays and preventive research, many efforts were made concerning construction delays and preventive management methods. But analysis of delay causation, which is a main key to solve the problems is not done, yet. Therefore, in this research causation delays are analyzed by characteristics of construction projects, which are type of projects, type of contracts, project participants, and general condition. As a result of the analysis, delay causation are proved to be different by characteristics of the projects. The research results will be used for prevention of time extension and dispute resolution.

Since the cases of time extension have continuously transpired in the public construction project, the potential of economical loss and claims is increasing because the concerned parties such as an owner or a contractor have not properly performed their own responsibility for time extension. One of the main reasons is that the present planning and scheduling do not support the method to apportion the proper responsibility to the right party. This problem has repeatedly led to time extension and made it difficult for the concerned parties to perform the responsibility for time extension. In order to overcome this problem, a framework of delay administration is required as the method to apportion the proper responsibility to the right party. To solve this problem, this paper aimed to develop the conceptual model and prototype system as the practical method to administrate delay causation. Furthermore, the verification result for the reliability and applicability throughout the case studies on real construction projects shows that the conceptual model and prototype system developed would help efficiently to administrate the delay causation.

If project time extension were required in the construction projects, either liquidated damages or extension costs should be applied according to causation of the schedule delays. However, in actual cases it is not applied so far according to the contract conditions. The reason why this situation happened Is that function of the present planning and scheduling is not working feasibly. The CPM schedule could not provide a proper solution for apportioning responsibility for the schedule delays. This situation could be considered as breach of contract and will cause potential disputes for schedule delay. Therefore, in this research process based contract administration model for construction delay claim is proposed to prevent schedule delay and solve the claims. The model is based on pro-active management for causation of delay to provide apportionment of responsibility and written evidences.

Glutaric aciduria(type 1) is characterized clinically by progressive dystonia and dyskinesia in childhood, pathologically by degeneration of caudate and putamen, biochemically by tissue deficiency of glutaryl-CoA dehydrogenase(GCDH), and is transmitted as an autosomal recessive traits. Mutations of the GCDH gene on chromosome 19 have been implicated in the causation of glutaric aciduria(type 1). Macrocephaly in infancy and crossing of percentiles for head circumference are real clues to early diagnosis. Acute neuroregression of dystonia following an initial phase of normal or almost normal development is a common mode of presentation, at times preceded by seizures. We experienced a case of glutaric aciduria(type 1) in a 13-month old girl. She was admitted due to development delay and choreoasthetoid movememt that developed after generalized tonic-clonic type seizures. She was diagnosed as having glutaric aciduria(type 1) based on brain MRI and urine organic acid analysis finding.

In Count case, the owners claimed from the charterers the amount of their loss resulting from the delay to the Count caused by the blockage of the channel due to stranding of the Pongola on the ground that this loss resulted from breach by the charterers of the safe port provisions. The Claim was referred to arbitration and dealt with on written submission. In a reasoned award, the arbitrators upheld the owners' claim. The charterers seek an order reversing the award or remitting it to the arbitrators for further consideration : (1) That the tribunal was wrong to find that the port of Beira was unsafe and that in consequence the charterers were liable to the owners in damages for detention. (2) That the tribunal was wrong to find that the port was unsafe in the abstract by reference to the fact that two other vessels had grounded there. (3) Having held that the Count was delayed for a little over four days by the fact that, after the charterers had nominated the port, the Pongola had grounded in the access channel, the tribunal should have held that the port was not prospectively unsafe. On the that the grounding the Pongola was caused by the characteristics which made the port an unsafe port to nominate for the Count. The court was held that it was not an independent event which broke the chain of causation between the breach of contract and the owner's loss. For those reasons, the court was upheld the arbitrator's award.
