1) The document introduces a new checklist for inspecting concrete plants that has been added to the QCS 2014 standards. 2) The checklist covers six main areas: factory conditions, raw material requirements, water and admixture requirements, batching plant requirements, laboratory requirements, and delivery ticket requirements. 3) The goal of the new checklist is to improve quality, transparency, and efficiency of inspections by providing inspectors and manufacturers a standardized list of quality criteria to evaluate during inspections.

Introduction.
QCS new and previous versions focuses on the concrete plant quality ,
the new version QCS 2014 part no. 7 in section no.5 has been amended
with a check list for concrete plants inspection , the chapter title also has
been changed to "Concrete Plants" instead of “ Batching Plant ", the new
title will be inclusive to all matters related to concrete plant .
The new amendment has been establish of trust and transparency among
governmental parties and manufacturers , and also to encourage
manufacturers to conduct self-audit their factories to improve quality,
through checking all the quality required points in the provided check list.

The benefit of new amendment.
 New to QCS.
 Focused on concrete plants.
 Transparency among manufacturers and governmental parties.
 Speed up the completion of inspection stage.
 Minimum requirements of quality specifications for concrete plants.

5. 5
Scope of inspection for concrete plants
at QCS 2014.
Inspection is the most important step to get the
conformity certificate or any certificate of concrete
plant .
The inspectors team mission is to visit the factory to
make sure that the following points are complying with
QCS 2014.
 Factory.
 Materials storage.
 Production lines .
 Laboratory .
 Product storage.
The National Committee has approved a list of
inspection steps, to improve the quality .
