Download our free sample specifications and schedules to see how NBS Chorus can help you.
Specifications for architecture, engineering, landscape, and the built environment give construction teams a detailed overview of the project work, required performance, and product selections. NBS Chorus is designed to make it easy for you to collate the data you need to produce robust specifications that power your projects and contains thousands of pre-written clauses and technical guidance referencing construction standards, making it quicker and easier to assemble your specification, saving you time and reducing risk.
With the help of our partners, we have put together a range of sample specifications for each discipline in both Uniclass 2015 and CAWS format.
We have also provided sample schedules, to demonstrate the client, planning and regulatory reports you can produce using the Schedules feature in NBS Chorus.
