Introduction.
Construction Materials Testing Laboratory Civil
Works Organisation was found by the renowned scientist Dr. Abdul Qadeer
Khan, NI & BAR, HI and ever since it is functioning under the sponsorship of
Khan Research Laboratories, Kahuta. This Laboratory is an integral part of
Civil Works Organisation which over the years has established its credibility
and attained the technical and administrative maturity. Construction Materials
Testing Laboratory, Civil Works Organisation is equipped with the most
modern and sophisticated machines and not only it has been very
successfully providing the quality control support to Civil Works Organisation
in execution of its projects but services are also offered to all leading
construction firms in the country. The utilization of this facility for provision of
skilled/technical manpower, with a view to combating the unemployment with
in the country and create chances for the youth to be absorbed abroad, was
the brain child of
Dr. Abdul Qadeer Khan, NI & BAR, HI. His personal
interest in the matter, therefore lead to the start of Construction Materials
Technician Courses in this Laboratory. This now is a regular feature and this
Laboratory is serving as the full fledged training institute for imparting training
in materials testing procedures.
2.
Objectives. The objectives of the course are:a. To impart the requisite theoretical knowledge and provide the basic
skill/practical experience to make the young trainees proficient in
material testing procedures.
b. To produce skilled manpower and provide trained laboratory
technicians to agencies engaged in engineering practices.
c. To contribute towards overall development of the country and
create chances for the unemployed youth to be absorbed abroad.
3.
Courses. Two Construction Materials Technician courses are
conducted at Construction Materials Testing Laboratory Civil Works
Organisation during the year. Course during first half of the year is tentatively
scheduled to commence in first week of April and course during second half of
the year is tentatively scheduled to commence in first week of October. This
however is subject to minor adjustment of the dates in accordance with the
prevailing situation. Course during first half of the year is purely meant for the
1
Matriculate level candidates. Candidates with qualification of secondary
school certificate with science subjects are eligible to apply. Course during
second half of the year is purely meant for the candidates with education level
as F.Sc and above including the graduate engineers (Civil Engineering) and
diploma holders.
4.
Organisation. Training team comprises of highly qualified and
experienced instructors and laboratory staff. Individual and personalized
attention to each student is the hall mark of this institution. Training is practical
oriented and maximum time is dedicated to the practical/field work. However
theory is taught in sufficient details for the conceptual comprehension.
5.
Block Training. Training is imparted in the following fields in the
form of lectures/demonstration/practical.
a. Soils
b. Aggregates
c. Cement
d. Concrete
e. Bituminous Materials
f. Steel.
