NBS Chorus for Small Works is a package created specifically for architects, engineers and designers who write specifications for smaller works and projects.
It includes all of the powerful features available with a subscription to NBS Chorus but with the choice of two new specially-selected libraries of content in a cost-effective package for small works.
Ultimately using NBS Chorus can help you to deliver more billable work, to a higher standard, with less risk to your practice.
Access focused specification content for smaller or less technically complex projects, with dedicated libraries for architectural or conventional mechanical and electrical work.
Each library brings together relevant systems, products, work sections and supporting guidance, helping you create clear, proportionate specifications without navigating content you are unlikely to need.
Content is updated regularly to the latest regulations and standards, giving you peace of mind and reducing the risk of things going wrong. Chorus helps you to maintain the golden thread of information for your projects, creating an accurate and up-to-date digital record.
Use the same specification writing, collaboration and coordination tools available in NBS Chorus, with content tailored to the scale and complexity of your projects.

"NBS Chorus is the future. It's quick and easy to use and has all of the functionality I need. The fact that you can edit the spec in Revit is very powerful as it reduced the chances of contradictory information in the model or specification...and it bridges the gap between Mac and PC, which could be the holy grail!"
Owner & Architect, J Foster Architects
"My favourite thing about Chorus is the ability to have multiple users making instant updates while developing models and the specification simultaneously. This is a must in the current era of the building industry".
Rider Levett Bucknall
NBS Chorus for Small Works is a specification-writing package for architects, engineers and designers working on smaller or less technically complex projects. It combines NBS Chorus functionality with a focused selection of specification content.
It is suitable for straightforward projects that do not have extensive specialist requirements. Examples include residential projects, refurbishments, small new builds, teaching blocks, student accommodation and relatively simple retail or industrial units.
There two content libraries available to choose from, including:
The CAWs library for architectural projects, which includes:
All 118 minor works work sections from NBS Building.
28 intermediate work sections that are most used or critical for small projects.
Minor works preliminaries.
A Uniclass library for building services projects, which contains mechanical and electrical systems and products used on smaller, conventional building services projects. It is a range of systems typically found in most mechanical and electrical installations, with support for low-carbon and renewable technologies.
It is designed for architects, engineers and designers who regularly prepare specifications for smaller projects. This can include sole practitioners, smaller practices and project teams within larger organisations.
NBS Chorus supports model and specification coordination through its wider platform features. Availability may depend on your subscription, so this should be confirmed against the current plans and features.
Pricing depends on the subscription, content library and number of users required. Contact NBS for a quotation based on your organisation and project needs.
Not necessarily. Suitability is primarily determined by the scope and technical complexity of the project. A relatively large building may still be appropriate where the construction and specification requirements are straightforward.
