VDI 3805 Processes to describe as IDM

Transcription

1 Processes to describe as IDM 1. What are the Processes initiated by? The Information Delivery Manual (IDM) aims to provide an integrated reference for processes and data required by BIM. It identifies the discrete processes undertaken within building construction, the required for their execution and the results of these activities. It will specify: where does a process fit and why is it relevant who are the actors creating, consuming and benefitting from the which is created and consumed how should the exchange be supported by software solutions is a German standard for data exchange of catalogue-data of AEC industry between manufacturers and CAE-systems for planning and calculation of plants in building services. It is the goal to bring to the level of an international standard. This will be done by modelling elements of by existing standards whenever possible. Nevertheless, it is expected that the core of will become a new ISO-standard, embedded in a number of already existing ISO-standards. One first step is to describe all the processes which are initiated by as IDMs. initiates several processes in planning of building services plants. These processes have to be described verbally before they can be described in form of one or more IDMs.

2 Processes to describe as IDM (Status ) 2 The following figure gives an overview about the processes which are addressed in this document. The white boxes denote process steps or subprocesses, and the blue boxes denote data which have been created in the previous step and are fed into the next step. Manufacturer, Service provider Collection Aquisition Software 1 Collecting of technical and geometric 1.1 Update and harmonize existing 1.2 Collecting and transforming into Certification centre Conformity-Test-Software 1.3 Conformance Test and Certification of Service provider Planner, Calculators Distribution Software CAE-System BIM data with embedded 2 Providing and updating Files 2.1 Providing 2.2 Updating 3 Using Files 3.1 Requesting data 3.2 Allocating data 3.3 Selecting 3.4 Embedding of into Plant Model 3.5 Embedding of Plant Model into BIM Building Construction Manager, Facility Manager Management Software Extracted 3.6 Extracting from BIM Process 1: Collecting of technical and geometric Process-Step 1.1: Update and harmonize existing In most cases, even within a single manufacturing company, the basic data for paper catalogues will be fetched from various sources which provide data in many differently structured forms. One reason for that is various lines have been started in over the history, and they often produce their own data in their own structure. In many cases technical data exists only in paper-drawings and paper diagraphs. The initial task of a manufacturer is to update and harmonise this raw catalogue data in collaboration with support and the involved -engineers. 1.1 Update and harmonise existing Product support, collecting of data needs Manufacturer's support and engineers updated and the Process is preparing the possibility for the following processes to be supported by software.

3 Processes to describe as IDM (Status ) 3 Process-Step 1.2: Collecting and transforming into Product catalogue data must be transformed into the format. This process requires efforts by manufacturers and. Software to generate complete including technical and geometrical data is available. The result of these efforts is one or more. 1.2 Collecting and Transforming into VDI 3805 At is a standardised machine-readable data format the There exists software to generate in userdialog complete VDI 3805 Process-Step 1.3: Conformance Test and Certification of Users of data need reliable data for their CAE-systems. Therefore, the generated data must be tested in a conformance test for: Readability Integrity Elaboration Correctness Completeness The result of these tests is a certificate. It will be written in the data file with a checksum code. 1.3: Conformance Test and certification of To get useful VDI 3805 Tested with certification the There exists a testsoftware for VDI 3805

4 Processes to describe as IDM (Status ) 4 Process 2: Providing and updating Files Process-Step 2.1: Providing 2.1 Providing There are two usual ways to provide : Manufacturers provide them on their own website Certificated from different manufacturers are provided on a neutral website, managed by an independent alliance To get data Tested with certification the There exist many manufacturerwebsites as well as neutral websites for Process-Step 2.2: Updating 2.2 Updating At least once in a year, the of a manufacturer need to be updated with data from new lines or changed s. to change and to complement the technical and geometric data. To get actualised Manufacturers or Updated the

5 Processes to describe as IDM (Status ) 5 Process 3: Using Process-Step 3.1: Requesting Planners and calculators with CAE-systems can browse the internet and search for data. Special data search programs can help them. 3.1 Allocating the To find in the web Location of Search-Software solutions Process-Step 3.2: Allocating Planners and calculators with CAE-systems can download from manufactures websites or websites of neutral communities. for automatic provision of newest updated. 3.2 Allocating the To allocate for the own CAE-systems Allocated Process-Step 3.3: Selecting Planners and calculators with CAE-systems have to select s from. Therefore CAE-systems provide individual solutions for selecting s. 3.3 Selecting Products the from VDI 3805 To get data for the selected to layout and to calculate it interfaces

6 Processes to describe as IDM (Status ) 6 Process-Step 3.4: Embedding of into a Plant Model 3.4 Embedding of into Plant Model Planners and calculators with CAE-systems embed selected s from data into their plant model provided by their own CAE-system. After embedding, the CAE-system plant model contains all the technical and geometrical data of the plant components to calculate, to simulate and to display it. In connection with a CAE-building model, all necessary interference checks are possible. To get data for the selected to layout and to calculate it the interfaces Process-Step 3.5: Embedding of Model into BIM 3.4 Embedding of Plant Model into BIM BIM (Building model) can manage building data generated by many different participants of a building's planning and construction. data of the implemented s has to be embedded into BIM for later use in plant models, when existing plants have to be enlarged or replaced. CAE-Systems can guarantee the completeness of the data of one. This can be tested by the same testing software as described in 1.3. At users of BIM models To manage data of the selected the BIM interfaces are available Process-Step 3.6: Extracting Model from BIM 3.5 Extracting from BIM data of the implemented s embedded into BIM can be used when existing plants have to be enlarged or replaced. CAE-Systems can extract data from a BIM model and use it in their internal plant models. At users of BIM models and VDI 3805 data To get data of the embedded to re-layout and to recalculate it the BIM interfaces and interfaces
