QCS 2014 Introduction Page 1
INTRODUCTION
The purpose of the technical regulation QS 27/2014 [Qatar Construction Specifications 2014 (QCS-
2014)] is to provide technical guidance in connection with the execution of constructions in the State of
Qatar. Such guidance includes the establishment of the minimum acceptable material quality and
workmanship for those kinds of work which commonly occur in engineered projects in the State of
Qatar.
Qatar Construction Specifications 2014 (QCS 2014) supersedes Qatar National Construction
Standards 2010 (QCS 2010) in all respects.
While working earnestly to benefit from new engineering developments, Laboratories and
Standardisation Affairs in the Ministry of Environment requests that all those undertaking works
projects in the State of Qatar to implement the specifications contained herein.
We welcome any observations, suggestions or additions for future issues.
QCS 2014 Document History Page 1
DOCUMENT HISTORY
The purpose of the Document History is to record changes to Qatar Construction Specifications. In the
event of a revision to the technical regulation, Laboratories and Standardisation Affairs in the Ministry
of Environment will issue the amended pages and re-issue the Document History.
The Document History pages should contain a description of the change, the issue reference and the
date of issue as noted below. The updated Document History should replace the superseded history
and the revised pages of the technical regulation should be placed in the appropriate position in the
technical regulation.
The technical regulation QS 27/2007 [Qatar National Construction Standards 2007 (QCS 2007)]
replaces Qatar Construction Specification 2002 (QCS 2002) and it supersedes in all respects.
The technical regulation QS 27/2010 [Qatar Construction Specifications 2010 (QCS 2010)]
replaces the technical regulation QS 27/2007 [Qatar National Construction Standards 2007
(QCS 2007)] and it supersedes in all respects.
Further, the technical regulation QS 27/2014 [Qatar Construction Specifications 2014 (QCS
2014)] replaces the technical regulation QS 27/2010 [Qatar Construction Specifications 2010
(QCS 2010)] and it supersedes in all respects.
