This study aims to propose a set of improvement devices for construction dispute resolution clause of public improvement project in Korea. To do so, the study addresses the system and procedure of construction dispute resolution in domestic and overseas, and reviews precedent cases, specifically focused of a selective arbitration case. In public sector's initiated contracts, the absence of c)aim procedure clause is unable to response to the claims in timely manner, and the ambiguity of clause o( selective arbitration make it difficult to resolve a dispute by arbitration. Thus, in this study alternative dispute resolutions are explored as a way to resolve various construction disputes of public-initiated project in developed countries.

A simulation technique can be used to analyze performance measures and support decision makings in manufacturing systems considering operational uncertainty and complexity. The simulation requires an input modeling procedure to reflect the target system's characteristics. However, data collection to build a simulation is quite limited when a target system includes manual productions with a lot of operational time such as construction equipment assembly lines. This study proposes a procedure for simulation input modeling using video data when it is difficult to collect enough input data to fit a probability distribution. We conducted a video-data analysis and specify input distributions for the simulation. Based on the proposed procedure, simulation experiments were conducted to evaluate key performance measures of the target system. We also expect that the proposed procedure may help simulation-based decision makings when obtaining input data for a simulation modeling is quite challenging.

Investigation results on shear connections design procedure which is conducted in Korea show that there are many communication problems between structural engineer and detailer, and there are unnecessary work procedures. To solve conventional connection design procedure problems, improved shear connection design procedure is suggested. Most of suggested design procedure is controlled by structure engineer, and the introduction of connections standardization makes computer aided design possible. Standardized connection details are satisfied with structural safety and constructability, and it improves design efficiency. Many problems which are caused by conventional design procedure are fundamentally blocked by using suggested design procedure.

We consider a postal transportation planning in the transportation network of the form of hub and spoke. Given mail sorting centers and an exchange center, available vehicles and amount of mails to be transported between mail sorting centers, postal transportation planning is to make a transportation plan without violating various restrictions. The objective is to minimize the total transportation cost. To solve the problem, a tabu search algorithm is Proposed. The algorithm is composed of a route construction procedure and a route improvement procedure to improve a solution obtained by the route construction procedure using a tabu search. Computational results show that the proposed algorithm can solve practically sized problems within a reasonable time and the quality of the solution is acceptable.

The governmental attitude toward private investment and financing for infrastructure projects has changed from the initial prohibition to the current encouragement in China, which has been embodied in the legal documents and administrative process. However, the problem of identification, bidding, and approval procedure for privately financed infrastructure projects has been observed in policies and administrative measures promulgated by different or even the same government branches, which is prohibitive factors for smooth project implementation. After analysis of the identification, bidding, and approval process of infrastructure projects, the authors proposed a simplified and alternative procedure and clarified the key points of relevant project documents.

Various approaches have been used in crack preparations and each of the approaches has advantages and disadvantages. Although the routing method has been widely used and seems to be the best approach among the approaches, it is not a complete solution for crack preparation. This paper compares and evaluates a pneumatic crack cleaning device (CCD) developed by Robotics and Intelligent Construction Automation group at Georgia Tech, over existing devices. Surveys were conducted to discover factors that affect the performance of crack/joint preparation work. Then, data for such information were collected via field tests for devices such as router, heat lancer, air blower and CCD. Performed field test results and follow-up interviews demonstrated that the utilization of CCD has potential to offer improvements in productivity, safety, and maintenance cost. An analytic hierarchical procedure (AHP) and economic analyses were conducted. The AHP analysis considered three factors including safety, quality and productivity while the economic analyses examined the alternatives in various ways. The results indicated that the CCD was ranked first and second for the AHP analysis and economic analysis, respectively. In conclusion, the field tests and results revealed that the utilization of CCD achieved satisfactorily in performance, quality, safety and control, and showed that it has high potential in crack cleaning practice.

If the construction delays are occurred during the project execution, the contractual parties should inquire the delay causes and the contractual obligation. Due to the compensation of damages, the interested parties and the contractual parties are placed on the adverse situation. For reasonable of the claim and dispute, the contractual parties are needed the objective and systematic procedure method to analyze the delay. The purpose of this study is to propose a formal process model considering the case of construction delay-claims.

Field instrumentation has been important part of construction management in embankment on soft ground. Most of all, well organized plan, instrumentation, maintenance, analysis and feed-back to the construction procedure are the key to the successful construction. In this paper, We review problems of field instrumentation has been performed at road construction on soft ground. And then, several proposals to improve field instrumentation and management are suggested

The paper presents a multifactor modelling of construction processes. There are three phases of the proposed extended procedure. Tools for these phases from chronometric test to verifying of the assumed model are indicated. Apart from the classic verification activities the method of artificial neural networks has been successfully applied. The paper presents the usage of these tools to model the process of assembly of structural corrugated steel plate structures.

A construction project with a total construction cost of over 10 billion KRW should be evaluated whether construction works are appropriately executed. The evaluation is carried out on quality management, process management, construction management, safety management, environmental management. The implementation period is within 60 days after completion of construction of the construction, from the time when the construction rate of the construction work has progressed by more than 90% to the construction cost. However, the participating construction engineers should prepare the evaluation within the period according to the evaluation criteria, but there are difficulties in preparation for the evaluation due to the reasons such as the change of engineers in charge and loss of data. Therefore, this study proposes the procedure of construction evaluation and adjusts timing of construction evaluation.
