## 2 Promoting the Utilization and Adoption of New Technology for Public Works

(1) New Technology Utilization System for Public Works

In order to actively utilize promising new technology developed by private sector businesses, a “new technology utilization system for public works” that utilizes the New Technology Information System (NETIS) is under operation. Up to now, there were 21 recommended technologies and 47 runner-up recommended technologies chosen as innovative new technologies that will further raise the level of technology concerning public works. Also, to promote efficiency of maintenance and management in the field, for the adoption of new technology in the field and the promotion of further technological development, NETIS is leveraged to set technical themes to use and evaluate the submitted technologies in the field.

## (2) Supporting the Utilization of New Technology

In order to promote the utilization of new technology in public works and other areas, utilization is evaluated at every design stage, and technology that provides great utilization benefits are designated by the ordering party when the construction is contracted. Also, for new technology that the contract ordering office is actively considering, a provisional unit price that helps with streamlining the contracting process was created for seven technologies from FY2012 to FY2014.

## 1 Improving Costing Technology for Public Works

For the purpose of ensuring the transparency of public works, various price data standards are made public. In FY2014, a rate revision was made for the administrative expenses based on “Revised quality assurance law” to secure reasonable profits, to be applicable from April 2015. The trial of the “Construction package type cost estimation formula” to improve the efficiency of estimation was started from FY2012, and then extended to FY2013. In response to the no-bidder/over-budget issue of recent years, the overhead cost correction for road maintenance projects in large urban areas and costing formulas that allows the reflection of the bidder’s estimates in expected pricing is being implemented on trial basis.

Additionally, the civil engineering work standard percentage was set along with the provision for the civil engineering work estimation points and estimation standards and in FY2014, taking into consideration the change in economic and social environment, the revision of percentage reviewed by the construction division corresponding to small-scale construction for the percentage for maintenance and repair as well as the revision of percentage reflecting the improvement in the construction efficiency based on the latest construction realities were executed.

Also, for construction machinery depreciation costs, field studies were carried out for the construction machinery owned by the contractors and the base value, maintenance and management costs, and operation costs were assessed and revisions are being implemented.

### .2 CIM and BIM Initiatives

A three-dimensional model is introduced from the planning, research, and design stages of public works, and it is also linked and developed at each stage of subsequent construction, maintenance, and management so that by sharing information among all the concerned parties of the project, the construction productivity system is made more efficient and sophisticated, while initiatives are being carried out to introduce CIM (Construction Information Modeling) for the improvement of quality assurance and environmental performance of public works, as well as to reduce lifecycle costs. A trial of 11 direct control businesses from all over the country was started from FY2012 as a model business, and its effect and issues are being verified. From FY2014, in conjunction with the trial, the examination for the CIM introduction and promotion is being advanced from the aspects of both system and technology through the cooperation of industry, academia and government.

From FY2010, BIM introduction is being trialled in 3 businesses, to verify the effect and issues of BIM (Building Information Modeling) introduction which can integrate and unify building information as well as visualize design content for the Government building projects. In addition, "Guidelines about Development and Use of BIM models in Government
