Ireland BIM

 

[1]

The document introducing BIM to the Irish public procurement system was a document published in 2015 and updated in 2019 under the name PGN 03/15 BIM. [2] The published instructions by the Department of Finance of Ireland are a short description for administration and BIM starters: requirements, instructions and actions. Here are the most important quotes from this document: The purpose of this guidance is to introduce BIM to departments and to explain why the government adopts it by delivering relevant infrastructure projects. In addition, the guidelines are intended to inform the Construction Centers of Procurement Expertise (CoPEs) and the supplier construction industry on how to use BIM during the procurement, delivery and operation of these projects. Adopting BIM will enable intelligent construction decisions, methodologies, safer working conditions, greater energy efficiency and a critical focus on the entire lifetime of equipment (or assets). Equally important are the benefits to the economy through better buildings and infrastructure provided by the government. The UK government has estimated savings for the UK construction industry and its customers £ 2 billion a year thanks to the widespread adoption of BIM 1. BIM is therefore an important tool for the government in delivering cost savings in its infrastructure projects.

BIM Maturity Definition

Level 0 Unmanaged 2D CAD, with data exchanged on paper or electronically on paper.

Level 1 Managed CAD in 2D or 3D format using BS1192: 2007 2, with data shared through a collaborative tool such as Web-based Shared Data Environment (CDE) with a standardized approach to data structure and format. No commercial data integration, finance or cost management packages.

Level 2 (BIM Level 2 required by April 2016) A managed 3D environment where each discipline creates its own models and all project information is electronically shared with CDE. Commercial data managed by Enterprise Resource Planning software (ERP) and integrated with BIM via proprietary interface or custom software. May use 4D construct sequencing and / or 5D cost information.

Level 3 (BIM Level 3 via TBC) Fully integrated collaborative model sharing process between the project team in a web-enabled BIM hub, compliant with the Industry Foundation Classes (IFC) open data standard. It will use 4D design sequencing, 5D cost and 6D design life cycle management information.

Delivery stage BIM requirements

(RIBA stage 0) Start Ending the BIM performance test

(RIBA steps 0-3) Provision Develop employer information requirements. BIM assessment of consultants and contractors. Execution plans

(RIBA steps 1-5) Delivery Develop a Project Information Model (PIM). Implementation of cooperation within the framework of shared data Environment.

(RIBA Stage 6) Communicate How PIM Built translated into Asset Information Model (AIM). Taking possession of the AIM.

(RIBA stage 7) Operation - In Use Design Assessment Maintain AIM

In order to assist SRO in implementing BIM, the following factors should be considered in agreement with CoPE: • Is the value of the construction project greater than the EU Threshold for Construction Works? • If not, does the Department want to pilot BIM on a lower value project? • Will BIM deliver project savings? To determine this, a BIM performance test should be completed at the commissioning stage. • If BIM is to be implemented, does the Department need to invest BIM Equipment, Software, and Staff Training? • Has the Department's property management function been consulted from the earliest stages of the project? • What are the EIR and key outputs for the BIM model in each of the design and delivery phases? • How will the Department access the BIM model during design, delivery and handover, and how will a secure CDE be established? • How will AIM be stored and available to the Department as described below? • Learn from implementing BIM in your project to be captured during project evaluation

BS1192: 2007 also covers file naming standards and conventions, naming layers, and project coordination. This should be understood as a best practice guideline for managing information about a construction project. The adoption of its recommendations throughout the construction industry are aimed at instilling efficiency in information management across the entire sector.

BIM PAS1192-2 (...) PIM "As Built" (...) The Information Model (AIM)

PAS1192-3 provides guidelines for managing AIM. The focus is on the operating phase of an asset, regardless of whether the main works acquired through the transfer of ownership or already existing in the asset portfolio have been put into operation.

AS1192-3 can also be applied to developing information during design and construction. Therefore, PAS1192-3 should be taken into account when developing the EIR

BS1192-4: 2014 is a code of practice for the framework for embedding information in BIM models. The embedded information is known as Building Operations Building Information Exchange (COBie) data. It is important to organize this data in BIM models to ensure that the information best matches the needs of the Department / CoPE at a key stage of the project assessment and / or asset management project.

EIR provides potential suppliers with the minimum information required by the Department / CoPE to achieve the BIM goals for the project. The EIR from the Baseline Form on which the Potential BIM Preparation Plan (BEP) is prepared, suppliers in turn provide departments with a benchmark for tendering and an assessment of the key work phase.

The pre-contractual BEP is prepared on behalf of ICT or IST by the Economic Operator. Before entering into a contract, the BEP should demonstrate the team's ability, ability and competence to apply BIM to the project and how the EIR complies with it.

The Supply Chain Assessment process informs the Contractor of the strengths and weaknesses of the BIM capability in his team. This allows the team to properly plan the EIR delivery. The Supply Chain Assessment process informs the team's BEP by developing its Task Information Delivery Plan (TIDP) and Master Information Delivery Plan (MIDP). CoPEs should reserve the right to examine the Supply Chain Assessment Forms prior to awarding the contract

EIR Data and Master Production Delivery Table (MPDT) 8 as part of the mail The award of a BEP contract becomes a contractual requirement by including it in the contract via the CIC BIM protocol.

CDE has been formally recognized by BS1192: 2007, which promotes its use and provides a data management structure. This is explained graphically in Fig. 3 below. BS1192: 2007 is a key requirement to achieve BIM maturity level 2 and above.

The CIC BIM protocol is a contractual document that guarantees that there is an obligation on the parties to provide certain elements of their works and services using BIM models. The protocol was developed for use on BIM Level 2 projects through an annex to the project contract. Conditions The protocol will apply from start to finish to all subcontracts under the project. Customer advisers and / or CoPE project managers should ensure that the CIC BIM protocol is included with the selected tenderer's contract and its contract terms and conditions apply throughout the supply chain of the subcontracting team

Project Information Model (PIM) delivery Upon award, a PIM will be developed by ICT or IST. Its development must follow the process defined by the CoPE in the EIR, in particular MPDT (…). The models will be produced by each discipline and grouped into a coordinated model developed by a lead team member as defined in BEP. Customized models and related information will be shared with the Department / CoPE and other team members at CDE.

AIM is a product of the CDE process and includes the "published" portion of the CDE containing the federated models, graphical and non-graphical documents and metadata to archive and extract data.

Key Assessment Points (data dips) in the BIM delivery process are required 3D digital models, 2D electronic information, and COBie data for presentation for Department / CoPE approval. File formats required by the Department / CoPE, Expected Level of Details (LOD) and Level of Information (LOI) for each drop in key milestones data should be reported in the EIR. Obtain 2D electronic information from a 3D digital or supply chain model that is coordinated with and electronically linked to the BIM model. CoPEs should become familiar with the LOD / LOI standards outlined in PAS1192-2 BIM Design and the NBS BIM Toolkit. The purpose of AIM is to be the single source of approved and approved information about an asset. Its data and geometry describes the resource, spaces and related items, and resource performance data, such as specifications, operation and maintenance manuals, and health and safety information.

Departments / CoPEs should review in their post-project assessments (PPE) how the AIM provided by ICT / IST can best be used within their assets and facility management strategies. The PPE arrangements should be used to inform the EIR of the Department's next infrastructure project. During the operational phase of the asset's lifecycle, the target should be updated to include all maintenance and repair work. This work may be undertaken by the IST during the defect period and / or Subsequently the departmental resource management teams (trigger - see PAS1192: 3)
