SpecifiedBy is now part of CausewayOne
We've updated our name and branding as the first step towards product data interoperability and the Golden Thread across the CausewayOne platform.
The features you rely on stay the same
For now, you can continue to use the www.specifiedby.com domain to access the same product data and search functionality.
Why the change?
CausewayOne is a construction operations platform used by 1,000's of contractors to design, win, manage and deliver projects.
CausewayOne Product Explorer will develop further to bring a central interoperable product data layer to all our contractor applications; by removing data siloes across parties & applications we can work towards a safer and more efficient industry.
