1. 　 Introduction

LCDM is:General concept of data sharing and system collaboration all through the construction lifecycle, not only execution process, but also maintenance process of completed objects.

*LCDM: Life Cycle Data Management

Goals are:To develop specification of data standards and information infrastructure, on which standardized data are registered, updated, and made effective use of, in order to promote data standards and make information investment efficient.

2. Current Issues of Information Sharing

•Digitalization of paper base does not make business restructuring go a long way.•IT development and standardization are dealt with separately in different fields, so that data linking is not smooth.
