In the many construction marketplaces in Japan, number of participants per bid has gradually decreased over the long term. Especially in the Tokyo metropolitan area, the number of single-bids has gradually increased. And that exposed some competition policy issues. The Tokyo Metropolitan Government had tried to cancel some single-bids in one-year period start from June 2017, but it had been abandoned due to the industry’s opposition and interference of public works projects by that measure etc. Large number of bid result data for building works over 20 years mainly for public building works in the Kanto region were analyzed.

In recent years, the management environment of the local homebuilders has been changing. There have been demands that they should grasp the reality of cost management. However, it has hardly ever been examined, because their methods are tacit knowledge in their business. This paper aims to understand the actual conditions of cost management in the homebuilders through the examination of the actual data on the cost management in the small scale building works. First, we obtained the documents on the cost of building works concerned. Secondly, we input the necessary information into a spread sheet program. Finally, we analyzed the change of the amount of all expenses in the itemized statements of contract price presented to the clients.

This is an estimation of the life cycle cost (LCC) of Japanese wooden detached houses. From a questionnaire research, we calculated the survival probability of various part of a house and remaining rate. The years of 50% remaining rate is taken as a standard repair interval to make a simulation model of life cycle refurbishment of a house. The refurbishment cost was estimated from interviews to the professionals or the analysis of real cases. Applying them to the simulation model, LCC of 30 year life is estimated to be 2.16 times of new construction cost, and that of 60 year life is 3.25 times.

This study aims to raise the employment rate for people with disabilities. It quantifies the monetary value of improvement effect, introduces universal design to existing buildings, and provides basic data for facility management planning. Twelve buildings owned by Company T have been investigated to evaluate universal design by applying the Comprehensive Assessment Systems of Universal Design Achievements (CASUDA) method developed by Sawada et al.

Various numbers of bidders exists in public building and/or construction works. Practically in Japan, exceedingly 10 bidders are participating in one bid. It is conceivable that number of bidders in one bid affects certain amount of influence on the competition. With using Friedman's model or Gates' model, which are known as maximum expected value models, the more the numbers of bidders increase, the more it becomes competitive, and the bidders have motive to present lower prices. Authors have tried to confirm the fact statistically with using recently released bidding results data of MLIT (the Ministry of Land, Infrastructure and Transport). In many cases, the ratios of bid price against ceiling price which are estimated by owner side engineers are confirmed decreasing as the number of bidders increases.
