AECO Markets Benefit from BIM Parameter Data Exchange for Revit Model Deliverables with Real-time API Access to CSI Standards

APRIL 7, 2021, SANTA MONICA, CA – With building information modeling (BIM) workflows increasingly dominating the design, estimating,  construction and facility management processes, BIM professionals need easy and immediate access to libraries and organizing principles. To satisfy this need, CDV Systems (CDV) and The Construction Specifications Institute (CSI) have announced a product integration connecting CSI’s widely-adopted construction industry organizing principles with cloud-based BIM libraries.

CDV Systems and 26 Degrees Software created COLLECTUS®, a remote BIM management product providing architecture, engineering, construction, and owner (AECO) firms and institutions a complete and fully functioning Autodesk® Revit® standards library accessible in the cloud.

The integration of the Crosswalk® gated webservice into Collectus addresses a serious challenge for the AECO industry– the lack of an automatic workflow to convert Revit asset parameter data from one set of CSI organizing principles to another.  While architects and engineers (AE) typically create Revit files using MasterFormat® organizing principles to manage the classifications of assets in their models, contractors receiving an AE’s models may prefer using UniFormat® organizing principles, and facility owners may prefer receiving their as-built Revit models using OmniClass® organizing principles.

Thanks to the Collectus and Crosswalk integration, Collectus users will have access to a direct link to Crosswalk from within the Revit model. This feature automatically converts MasterFormat asset parameter data for all Revit system and type family assets into UniFormat and OmniClass parameter data. All 18,000+ family asset content in the Collectus Revit library are based on using Masterformat organizing principles. Collectus users can now update all family MasterFormat parameter data within their models to Uniformat and OmniClass parameter data with a single click.   

“We could not be more excited to work with CSI in this dynamic new way”, says Cyril Verley, Founder and President of CDV Systems. “Using Crosswalk within Collectus, our clients can now deliver their Revit project models from design, to estimating, procurement, construction, compliance, to final as-builts without any time wasted converting classification data from one format to another. Since the connection is always live, any industry classification changes made by CSI are directly available within Collectus ensuring their classification data is always accurate, while dramatically reducing time spent on classification translations.”

“This use case is exactly what we built Crosswalk for,” noted Mark Dorsey, CEO of CSI, “Crosswalk brings the organization of construction information into the 21st century, enabling  the vision and development of built environment entrepreneurs like COLLECTUS,” he added.


Crosswalk® is the first API to network CSI’s MasterFormat®, Uniformat®, and OmniClass® organizing principles with the world’s building professionals, construction technology platforms, and data flows. Created by the Construction Information Network, Crosswalk is the digital engine for the AECO community, driving plans, protocols, and performance across the lifecycle of a construction project.

Crosswalk was created by The Construction Specifications Institute, Inc. a national not-for-profit association of more than 7,000 members dedicated to improving the communication of construction information throughout continuous development and transformation of standards and formats, education and certification of professionals to improve project delivery processes. CSI members work tirelessly to effectively communicate the designers’ vision, the material producers’ solutions and the constructors’ techniques to create outstanding facilities that meet facility owners’ objectives.
