CALS/EC has been promoted for 17 years since 1996 by MLIT and JACIC.

Electronic delivery couldn’t catch up with ICT and social environment.

And systems were tied up in many strict standards, and each phase

became independent, and an information sharing was not possible.

CIM was aimed at IPD and IFC model of the thought of BIM as

innovation of a new construction production system in 2011 by MLIT.

Pilot implementation began as kickoff by JACIC seminar in 2012.

MLIT had 11 trials of the design projects in 2012.

In 2013, seven cases are going to be tried as a construction project.

Recommendation of CIM For the innovation of the construction production system.

A) In construction site, we mobilize all the ICT such as 3D

models and carry out model construction.

B) we circulate by data for the idea from maintenance.

C) Each engineer reforms consciousness and uses the ICT

forward.

2. Method of Concurrently shared product model

Conditions and resource, environment

1) Conditions

a. Utilization scene is clarified, and it is a main premise to be the useful model.

b. Not a model to make in the short term, but in the long term is necessary.

2) Viewpoint

We must pay attention to PM, QCDSE, PDQ, SCM/DCM, risk and finance.

Work flow

a. BIM related information collection

b. IPD, understanding of BIM, inspection

c. IPD, quotation

We are divided into two of the next specifically in the long term.

Point of view

In conformity with IPD, project management need a communication

tool supporting knowledge management.

In addition, it is important to cooperate keeping the relations and

take load for a previous phase .

Therefore, we would perform the risk management of the project

appropriately.

It is possible to prevent rework because actual operation contractor

makes a construction plan with a designer from the early time.

Based on these factors, we can shorten term of works and reduce

cost and improve quality, and accomplish improvement of the

productivity.

Here is that CIM learns from BIM. However, BIM is only a tool of

IPD.

I. Short term correspondence (Trial construction)

It’s important to make 3D model early, and also make useful

educational system. At first approach from seeds-oriented is realistic.

Proof procedure is as follows. ① For the first phase, making a compatibility map every business processes

② The plural presentation by the same process

③ Trial, and proof ④ Effect inspection ⑤ Optimization of the process

⑥ Compatibility confirmation between processes

⑦ Extraction, rearranging of effect inspection and the problem

⑧Sophistication ⑨Phase optimization

II. Medium-and-long term correspondence We plan a three-dimensional shape model, unified DB based on an international

standardization, the CIM base model corresponding to the compatibility of the

common ground concerned every medium-and-long term for domain.

examination procedure is as follows.

① Rearranging, examination of data models such as BIM

② Construction sector (Kind of construction; Domain)

③ Setting of the profit utilization scene, effect assumption

④ PM element about each model are risk, process, multiplication, simulation

⑤ Development of a concept, the outside, and the internal schema

⑥ Development of each data model, and unification

⑦ Construction (unification of each base) of the general country base

⑧ Examination and maintenance of the light and shade model

What we plan teaming including orderer designer, actual contractor and supplier in

an early stage, we can disperse the risk of the defects by learning IPD of AIA.

Method by being structured of collection, accumulation, analysis,

utilization

On the common infrastructure, platform, concurrent processing and

parallel processing which exchange of plural work shares large-

capacity (Volume) (Variety) of Big Data by high-speed processing in

real-time (Velocity).

A. Unified Modeling CIM DB

We suggest information service about CIM in JACIC.

B. CIM Integrated Database

The CIM server which will be the platform of the CIM model

assumes non-structure data a basic database, and the non-structure

data include structure data. About LCC (life-cycle Cost) of data, we

consider TCO (Total Cost Ownership) from outbreak to the disposal.

Figure is a plan of the images of the CIM unification database.

2.2 CIM model structure

The technical problem rearranging in the CIM model

In the case of integration and the visualization of the 3D structure, we unify each

part model with the 3D model adding unification with the attribute information.


13

Fusion with existing data and new data, structure of being structured and non-

structured model

We let various forms and old and new data fuse as Big Data on a precision and

particle size.

Properties of matter, an attribute: Multiplication (amount calculation), simulation

A process model, difference in construction plan amount calculation technique,

quantity of soil coordinates method average section method voccel model, surface

model

The use in various scenes where a design leads to construction, maintenance, a

plan (newly), update

Geometry shape information (x, y, z:) Three-dimensional) + time (Time,

delivery:) The concurrent use of process, five dimensions of procurement speed)

+ cost (multiplication, the volume) = models, attribute information (materials),

process, process, geography space, role information, mutual related information

2.3 Each domain model, common resource

Unification on the three-dimensional platform

Effectiveness and the problem of Infrastructure Modeler soft on

the three-dimensional platform

•Cooperation — We unified models from plural data sources and

perform confirmation and a plan of the application procedure

•Maintenance — Using an intelligent industry model, we maintain

more reliable attribute information.

3. RESULTS

We investigated element data and attribute item on specification of

both model and software to confirm validity of the precision of model.

From these findings we found out that software with double precision

of the input and output and calculation columns was most. We show

rearranging of the data precision in Table .

Based on these results, we arranged the indication to road cross-

section data and alignment data exchange standard, and examined item

of specifications and guidelines, and arranged it as LOD.

Depending on a use, it is necessary to raise data precision than LOD3.

In addition, it is necessary to display precision quality about the LOD

of three-dimensional data.

As LOD for CIM in lifecycle infrastructure model, Figure is shown.
