BUILDING INFORMATION MODELING (BIM) SPECIFICATIONS

1. Introduction LREDC is successfully applying BUILDING INFORMATION MODELING (BIM) technologies to monitor quality, time and costs; to mitigate PROJECT risks; and to support site logistics planning throughout the PROJECT. A BUILDING INFORMATION MODEL is a three dimensional representation in electronic format of building elements representing solid objects sections, elevations, plans, renders, 3D walkthroughs, specifications, details and technical information and materials embedded in the model , With true to scale spatial relationships and dimensions. A BUILDING INFORMATION MODEL to be useful for its intended purposes should include as much of the available information as possible. Other intended BIM uses are:

• Design approval including design coordination and clash detection analysis

• Construction and Site Management including but not limited to progress monitoring, cost control, site and logistics planning (e.g. optimizing logistic roads layout, security accesses and coordination of dewatering routes), reporting of testing and commissioning activities

• Close-out Documentation handover to be used for information handover to CGIS and other local authorities, and to prepare operation and maintenance of assets

The model shall be extended by CONTRACTOR to include any and all activities directly or indirectly related to design, construction and documentation of the PROJECT as LREDC may from time to time request. CONTRACTOR shall provide federated and fully coordinated BUILDING INFORMATION MODELS representing the latest available drawings at specific PROJECT milestones, developed to an agreed and acceptable Level of Development (LOD). Non-graphical information shall be tailored to allow seamless import into LREDC’s PROJECT database – the LREDC Data Store. All BIM milestones are conditions for approval of CONTRACTOR’S invoices.

2. Definitions

• BUILDING INFORMATION MODELING (BIM). A managed process, involving the recording, exchange and application of pre-defined, trusted, structured digital data; representing physical, functional and spatial characteristics of a facility. BIM is a general concept and not a specific software application.



• BUILDING INFORMATION MODEL. A BUILDING INFORMATION MODEL is a digital representation of the PROJECT, or a portion of the PROJECT, and is referred to in this DOCUMENT as the “Model”. Additional information is assigned to MODEL ELEMENTs.

• MODEL ELEMENT. A MODEL ELEMENT is a portion of the Model representing a component, system or assembly within a building or building site.

• DOCUMENT. A written or printed paper, item or computer data file containing information for use in the briefing, design, construction, operation, maintenance or decommissioning of a construction PROJECT, including but not limited to correspondence, drawings, schedules, specifications, photos, calculations, spreadsheets. DOCUMENTS are created and stored for the PROJECT in digital form.

• PROJECT. As used throughout this instrument, “PROJECT” means the PROJECT identified in the CONTRACT as the construction of Transfer Packages CP01-C1, C2 and C3.

• LREDC DATA STORE. PROJECT-wide SQL database containing Digital Data linked to MODEL ELEMENTs through Unique Identification Attributes (UIA). The LREDC DATA STORE contains information required to monitor and streamline Design, Construction and Operation.

• LEVEL OF DEVELOPMENT. The Level of Development (LOD) describes the minimum dimensional, spatial, quantitative, qualitative, and other data included in a MODEL ELEMENT.

• LOD 200. The MODEL ELEMENT is graphically represented within the Model as a generic system, object, or assembly with approximate quantities, size, shape, location, and orientation. Non-graphical information may also be attached to the MODEL ELEMENT.

• LOD 300. The MODEL ELEMENT is graphically represented within the Model as a specific system, object or assembly in terms of quantity, size, shape, location, and orientation. Non-graphical information may also be attached to the MODEL ELEMENT.

• LOD 350. The MODEL ELEMENT is graphically represented within the Model as a specific system, object, or assembly in terms of quantity, size, shape, orientation, location and interfaces with other building systems. Non-graphical information may also be attached to the MODEL ELEMENT.

• LOD 400. The MODEL ELEMENT is graphically represented within the Model as a specific system, object or assembly in terms of size, shape, location, quantity, orientation and interfaces with detailing, fabrication, assembly, and installation information. Non-graphical information may also be attached to the MODEL ELEMENT.



• LOD 500. The MODEL ELEMENT is a field verified representation in terms of size, shape, location, quantity, and orientation. Non-graphical information may also be attached to the MODEL ELEMENT.
