Technical Bulletins

In 2019, the Committee completed a review of the Manitoba Technical Bulletins with the Manitoba Association of Architects. These are available for review and printing. In addition, the WCA Standard Practices Committee has several documents that are NOT endorsed by other professional organizations at this time, but which are nonetheless important for the industry.

Manitoba Technical Bulletins Series

More than 30 years ago, WCA and the Manitoba Association of Architects began developing standard Technical Bulletins to provide clarification and guidance on construction issues.

New PB #4 – Bid Irrevocability Period During Persistent Material Price Volatility
