NMS updates

The National Master Specification (NMS) is the most comprehensive master specification in Canada serving as an easy-to-use framework for writing construction project specifications. To maintain their relevance, NRC publishes a series of updates on a quarterly basis. The following represents the latest set of updates.

NMS summary of updates 2017-01

The 2017–01 NMS includes a new section that focuses on removal and salvage of construction materials and forming a preliminary component to other selective demolition activities. It also covers updated sections related to deconstruction of structures, removal of construction materials, removal of underground storage tanks, conservation treatment of period masonry and stone, as well as sections for cast-in-place concrete, wood treatment and rough carpentry. As a significant enhancement to the data set, descriptions are now provided for each NMS section. The descriptions will help users find appropriate sections, and will be searchable on NRC’s website, and within some of the third party software tools.

NMS summary of updates 2016-01

A series of corrections were made as part a of a general quality assurance review. Thousands of punctuation and spelling changes were made to improve consistency and ensure Canadian spelling throughout, for example 'colour' rather than 'color', 'fibre' rather than 'fiber'.

Enhancements were also made to align with SectionFormat™, such as listing standards under a heading of Reference standards. For consistency in tab levels, Abbreviations, Definitions and Referemce standards were all promoted to top-level article titles. Other changes were made to reflect specification writing language such as changing the requirement to submit (rather than provide) engineer sealed drawings.

There are over one hundred references to Codes Canada 2015 throughout. Each was reviewed and updated to the 2015 editions. There are a few exceptions related to seismic design that require additional review before updating code references are updated.

A few sections were renumbered or re-titled to align with MasterFormat® and a more extensive adjustment will be released on the next NMS publication.
