SECTION F: BIM REQUIREMENTS

REALITY CAPTURE (LASER SCANNING / 360 PHOTOS)

The planned practice to use reality capture devices such as laser scanning, 360 photography, or drone photogrammetry to document existing conditions or as-built conditions for the purposes of construction coordination.

PHASE: OPERATE

RECORD DESIGN BIM

The Design Team members shall conform their Design-Intent Models with all the information that is released by the Design Team throughout the course of the design and construction processes. This would include but not be limited to all Addenda, Bulletins, Supplemental Sketches (ASIs), Construction Change Directives (CCDs) and Change Orders (COs) per the Project Deliverables. This deliverable will be expected to be handed over to the Owner at Substantial Completion.

AS-BUILT FEDERATED MODEL HANDOVER

Compiling of all final Record Design Models plus As-Built Trade Contractor models into one final Federated Model.

AS-BUILT TRADE PARTNER MODELS & DRAWINGS HANDOVER

As-Built Modeling: the final as-coordinated and as-built verified representation of Trade Contractor models.

☒ Misc. Metals Model (MMC) ☒ Low Voltage Security Models (SEC)

2. BID SCHEDULE, PACKAGES AND WORK CATEGORIES

The disciplines noted below are required to provide 3D BIM content, adhere, and perform to the specifications set forth in this BExP. *Note: Work Categories (WCs) listed below marked with an ‘X’ and marked with an asterisk (*) are not required to provide 3D model content. However, these WCs are required to coordinate traditional 2D shop drawings with 3D model content provided by the Engineer of Record and McCarthy to ensure no impacts to field coordination at a minimum. Trade Contractor performing work for these Work Categories may opt to provide 3D model content to ensure proper coordination as part of their base bid at no additional cost to the project.*

3. MODEL CONTENT – LEVEL OF DEVELOPMENT (LOD) DEFINITIONS BIMForum AGC LOD Specification 2019

Models and Model elements created by/with all Model Element Authors (MEAs), Level of Development (LOD) and any specific attributes important to the project are to adhere to and be documented using the current BIMForum’s AGC LOD Specification 2019 that can be found at http://bimforum.org/lod/

LEVEL OF DEVELOPMENT vs. LEVEL OF DETAIL

LOD is sometimes interpreted as Level of Detail rather than Level of Development. This Specification uses the concept of Level of Development. There are important differences. Level of Detail is essentially how much detail is included in the model element. Level of Development is the degree to which the element’s geometry and attached information has been thought through – the degree to which project team members may rely on the information when

using the model.

In essence, Level of Detail can be thought of as input to the element, while Level of Development is reliable output.

LEVEL of DEVELOPMENT DEFINITIONS PER PHASE

AIA Level of Development (LOD) Definitions are as follows (also refer to the referenced AGC LOD Document):

LOD 100 – Compatible with Conceptual/Schematic Design Phase

The Model Element may be graphically represented in the Model with a symbol or other generic representation but does not satisfy the requirements for LOD 200. Information related to the Model Element (i.e. cost per square foot, tonnage of HVAC, etc.) can be derived from other Model Elements. BIMForum Interpretation: LOD 100 elements are not geometric representations. Examples are information attached to other model elements or symbols showing the existence of a component but not its shape, size, or precise location. Any information derived from LOD 100 elements must be considered approximate.

LOD 200 – Compatible with Design Development Phase

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-graphic information may also be attached to the Model Element. BIMForum interpretation: At this LOD elements are generic placeholders. They may be recognizable as the components they represent, or they may be volumes for space reservation. Any information derived from LOD 200 elements must be considered approximate.

LOD 300 – Compatible with Construction Document Phase

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-graphic information may also be attached to the Model Element. BIMForum interpretation: The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension callouts. The project origin is defined and the element is located accurately with respect to the project origin.

LOD 350 – Compatible with Construction Document/Bidding/Procurement Phase

The Model Element is graphically represented within the Model as a specific system, object, or assembly in terms of quantity, size, shape, location, orientation, and interfaces with other building systems. Non-graphic information may also be attached to the Model Element. BIMForum interpretation: Parts necessary for coordination of the element with nearby or attached elements are modeled. These parts will include such items as supports and connections. The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension callouts.

LOD 400 – Compatible with Construction Coordination/Fabrication Phase

The Model Element is graphically represented within the Model as a specific system, object, or assembly in terms of size, shape, location, quantity, and orientation with detailing, fabrication, assembly, and installation information. Nongraphic information may also be attached to the Model Element. BIMForum interpretation: An LOD 400 element is modeled at sufficient detail and accuracy for fabrication of the represented component. The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension callouts.

LOD 500 – Compatible with Record Models, As-Built Models for Closeout/Handover Phase

BIMForum interpretation: Since LOD 500 relates to field verification and is not an indication of progression to a higher level of model element geometry or non-graphic information, the BIMForum LOD Specification does not define or illustrate it. The below definition of LOD 500 is specific to McCarthy’s expectations after 100% Construction Documents and post-Trade Coordination sign-off for model maintenance:

1). LOD 500A relative to Maintaining Record Design-Intent Models:

Representative of the Record Design-Intent Models being maintained with any official changes to the Work, through Substantial Completion. Field Verification of the Record Design-Intent is not a direct requirement of
