PROJECT OVERVIEW
The project Vicem Management and Transaction Building at land plot 10E6_ Cau Giay new
urban area_Cau giay district, Ha noi city, conducted by employer Vietnam Cement Industry
Corporatin. The construction has 31 over ground floors and with the height of 139.6m, and total area
around 8450m2, construction area 2800m2 and total floor area 81060m2.
The main purpose of quality control schedule is providing personnel procedures, processing,
installation, maintainance, which shall be executed in the contract. To insure progress rate, material
quality to meet employer’s requirements, all factories and facilities, equipment are used and
maintained by professional and qualified engineers, technician. Regarding to new updated
equipment, machine, we have support from overseas specialists, manufarer’s technical staffs to
operate smoothly and efficienctly
We shall carry out period quality examination to insure that the installation of aluminium system
follows design, execution is conducted effectively. Besides, correct system installation shall support
the whole Phi kha’s system which helps employer have a exactly understanding about certain and
unavoidable in the area.
2
EXECUTION SECTION OF CONSTRUCTION
The work shall be divided into 5 sections:
1. Doors, windowns, glass aluminium walls
2. Stone walls
3
IMPORTANT NOTES AND DEFINITIONS
Quality control staff have examined the design drawign, specification of project and checked all
detail notes. They have already known the list of section needed for inspectation
4
Quality control ( QC )
All procedures and solutions shall be conducted carefully and efficiently to obtain and maintain
quality of each work section, so regular inspectation for those procedures, solutions, specifications is
needed to make employer satisfied with the work quality.
The main tasks are seeking, forecasting to eliminate causes which can lead to negative effect on
work quality, so quality criteria must be strictly applied at the start until completion time.

Quality assurance (QA)
Quality assurance is preventation from quality control problems by means. The efforts of quality
control is determined and directed by planned goals based on strick requirements for system
execution
This is related to procedure evaluation and checking ability to gain high quality outcome,
including documents approving that quality is good.

DETAILED PROCESS OF QUALITY CONTROL
Input material control
I.1 At processing factory
All materials which are used for glass wall and cladding system shall be recorded into receiving
minutes. Transportation of materials such as aluminium, glue, glass, mattress, structure glue, sticky
plasstic, machine and other equipment to fatory shall be inspected. Inspectation shall be conducted
anytime for all materials, and reports shall be made based on requests. Quality control engineers
shall record all materials which have different specification from requirements, design drawing of
construction, also report and classify into 2 categories: accepted and unaccepted materials
I.2 At the Site
