Good Building Practices Guideline Is Intended to Illustrate Those Differences

kNK5 Z?m1Z Government of Nunavut Nunavut Kavamanga Gouvernement du Nunavut Good Building Practices Guideline Second Edition December 2005 FOREWORD Building in the North is indeed different than building in more temperate climates. The Good Building Practices Guideline is intended to illustrate those differences. It is aimed at providing architects, engineers, building contractors, suppliers, facility administrators and operators with a comprehensive set of guidelines for building in the North. The Good Building Practices Guideline assumes an advisory role, while renewing the challenge to builders to be innovative in applying the practices. Builders are encouraged to present alternatives to the suggestions detailed in the Good Building Practices Guideline, or to present new or innovative ways of resolving technical problems or of reducing building life-cycle costs. The Good Building Practices Guideline incorporates years of experience in northern construction practices. The Good Building Practices Guideline was refined through input from architectural and engineering consultants, building contractors, suppliers, facility operators, Community and Government Services and client department staff, who worked together to achieve a consensus regarding northern building practices that are appropriate, economic and realistic. Simple, straightforward examples are used to illustrate and validate the practices. The guidelines are not intended to replace mandatory codes or regulations, but to supplement the National Building Code of Canada, specifically where the GN believes that: • More stringent practices should be applied relative to those of the National Building Code of Canada or the local municipality • Code requirements should be clarified • Its experience has demonstrated that conditions particular to remote northern communities require an approach different from typical Canadian building industry practice • Its proven preferences for specific products, systems or methods should be employed We are confident that all northern builders will find the Good Building Practices Guideline to be an indispensable guidebook, and challenge users to contribute towards its improvement in the next edition. Tom Rich Deputy Minister Community and Government Services ACKNOWLEDGEMENTS In preparing the Good Building Practices Guideline (Second Edition), the Technical Services Division of the Department of Community and Government Services, Government of the Nunavut, has drawn upon the assistance of numerous individuals from within the Department and from private sector agencies. Many of them contributed technical writing and comments to this guidebook. The Good Building Practices Guideline became a reality because of their participation. We would like to express our appreciation to the many northern architectural and engineering firms, including AD Williams Engineering, Park Sanders Adam Vikse Architects, Ferguson Simek Clark Engineers and Architects, Pin-Matthews Architects, and Thorn Engineering for their important contributions to the production of this document. Our thanks also extends to the Arctic Energy Alliance and Envirovest Energy Ventures Inc. for providing beneficial information related to energy-saving initiatives for the Government of Nunavut. Community and Government Services in-house technical and administrative staffs have played a key role in contributing to and coordinating the development of this guidebook. We also wish to recognize community and Government Services Regional staff for critiquing this guidebook.

Over time, certain products or approaches to construction have proven successful and have been adopted by property developers, design consultants and builders working in Nunavut. It is hoped that your comments and opinions will lead to further revisions and additions that will keep the document current and relevant. Criteria for Good Building Practices Guideline These technical guidelines do not replace any mandatory Codes or Regulations. Rather, they cover the following areas: a) Where more stringent requirements should apply than the National Building Code of Canada or local municipal requirements b) Where there is a need to augment or clarify a code requirement c) Where conditions peculiar to a remote northern community require an approach different from typical Canadian building industry practice d) Where specific products, systems or methods have been developed and have been found to be superior for northern conditions Detailed studies or reference materials are provided in the Appendix or noted within GBPG for interest only, and unless otherwise stated, do not constitute a part of the GBPG. Application of Guidelines The GBPG has been prepared as suggested guidelines for obtaining good value and quality buildings. The GBPG may be applicable for renovations to existing buildings, tenant improvements in leased facilities, or utility buildings. These guidelines come from studying buildings typical of the majority of buildings found in most communities in the Nunavut, that is small-scale low-rise structures designed to accommodate people. The GBPG may be less applicable to unusual or highly specialized buildings, or unusually large buildings. Development of the Good Building Practices Guideline The GBPG incorporates collected observations obtained from builders, designers, building operators and users. A substantial portion of the information was collected by staff of the Technical Services Division and Regional Project Management, in consultation with other stakeholders in the construction industry. Revisions Periodic reviews will be undertaken to reconfirm, revise or update the content of the Good Building Practices Guideline. Your comments and suggestions are invited.

Buildings should be designed specifically for the northern climate and other physical parameters of the site, as well as for the minimum capital cost consistent with lowest
