WHAT THE NSS IS
The National Site Standard is an evidence-based governance framework for construction sites and training environments.
It sets clear expectations for the conditions, behaviours, reporting routes and leadership accountability that shape day-to-day workforce experience. It is designed to help organisations move beyond good intentions and demonstrate, through evidence, that better standards are understood, implemented and maintained.
NSS focuses on the barriers that affect women entering, remaining and progressing in construction. In doing so, it helps create safer, more professional and better-performing environments for everyone.
THE INDUSTRY CHALLENGE
Construction cannot meet future demand without attracting and retaining more people.
The sector continues to face skills shortages, early attrition and an underrepresentation of women, particularly in site-based roles. Recruitment alone will not fix this. The environments people enter must be consistent, inclusive, well-managed and capable of supporting long-term progression.
NSS provides the structure, evidence and assurance needed to improve workforce standards across sites, projects, supply chains and learning environments.
Over 240,000
extra construction workers are needed by 2029.
Around 35%

Up to 750,000
construction retirements are expected between 2021 and 2036.
47%
of construction workers leave the industry within the first 5 years
14%
of the industry's workforce are female with just 2% of site-based personnel being female.
