INTRODUCTION
BENEFITS
Easy to use User friendly guides to assist
Speed in taking off Only by inserting dimensions (nos, length, width &
height) quantites such as excavation, concrete work,blinding and formwork are automatically calculated
Schedules given assist the user in taking off in a
systematic manner
This measurement schedule has been developed to be
used as a tool to facilitate QS staff in taking off quantities
of excavation, concrete, reinforcement and formwork infoundation and RC structure
