Construction
is one of the most complex industries due to its heavy influence in lots of
elements and involvement with many parties such as the Owner, the Consultant,
and the Contractor etc.. This leads to the difficulty in managing the quality
of product in construction. Since clients are becoming more and more demanding
on the product quality, construction companies in this high competitive market
are now striving to improve the quality management aspect as much as
possible. There is no doubt that apart
from the traditional relationship, quality has become one of the key factors in
the survival and success of construction companies.
In
Viet Nam nowadays, there are many issues related to the quality of construction
project. Therefore, one being able build a quality management system for a
particular project will certainly gain a competitive advantage over the
competitors and meet the client’s expectation accordingly.
Recently, there
have been a lot of foreigner investors come to Vietnam and invested in the
development of international schools with high quality facilities to attract
potential parents and satisfy their expectation. Unfortunately in some cases,
the investors cannot get what quality they were guaranteed due to the following
problems:
1. Project delayed
2. Poor
coordination between Contractor and Sub-contractors
3. Miscommunication
among participants’ parties
4. Poor
management in terms of scheduling, planning, controlling, etc.
5. Low quality
in finishing work.
Mr.
Nguyen An Vi Nghia made a case study which objectives were to: (i) study owner
project management for managing quality performance starting from design,
construction and handover; (ii) discuss strengths and weaknesses; (iii) propose
recommendations; (iv) highlight lessons learnt; and (v) develop a Quality
Management System framework.
Conclusion
The following conclusions were drawn after accomplishing the objectives:
Objective
1: The purpose of this study is considered and analysed the way the owner
managed the quality performance of school project from the design stage to
handover construction stage. The author found out that the way the owner
managed the quality of project was not good enough, and there were many serious
problems remained.
Objective
2: Strengths and weaknesses
Some
major strengths of project were identified such as:
1.
Standardized information by owner such as colour, size of function rooms,
furniture arrangement, design brief, draft design, etc.
2.
Owner has the technical team, who able to support with the design and
construction work.
3.
The school is a simple building for construction.
4. The owner is an expert in school operation and they have run many
schools before.
However,
some major weaknesses and sources of the problems were also identified such as:
1.
The owner’s requirements and expectation were unclear from the beginning. Owner
was the source of problem
2.
The designer did not conduct a land survey before designing. Designer was the
source of problem
3.
Tender document was insufficient and inconsistent. Owner, designer and
appraiser was the source of problem
4.
Project members did not know clearly about the project’s objectives. Owner was
the source of problem
5.
Unrealistic schedule. Owner was the source of problem
6.
Unclear responsibilities and scope of works in the contract. Owner was the
source of problem
7.
Owner did not test and commission before signing off the handover letter. Owner
was the source of problem
8.
Owner did not prepare any form or check list for inspection. Owner was the
source of problem.
Objective
3: Recommendations
In
order to solve and to prevent the problems, the author proposed the following:
1.
The owner needs to provide clear requirements and expectation in the beginning
of each step
2.
The owner needs to request designers to go to the land site to study the land
condition and the design should be suitable with land condition.
3.
The owner should provide sufficient tender document for bidding and make sure
that the contractor’s proposals followed the template. By this way, it will be
easier for the owner to compare “Apple to Apple”.
4.
Before the start of the construction, the owner should organize the meeting to
brief all project members about project’s goal and their expectation for the
project
5.
The owner needs to have a good master schedule to ensure that the construction
work has sufficient time for proper construction. They need to recognize that
“if we have unrealistic time, we will not have good quality product.
6.
Besides providing clear requirements and expectation, the owner also needs to
write down clearly the responsibility and scope of works of other parties
related to project.
7.
The owner needs to conduct the testing and commissioning of the whole school
before signing off the handover letter. For efficiency of the testing and
commissioning step, the owner needs to appoint people who have fully knowledge
for testing and commissioning parts.
8.
To save the inspection time and more efficiency inspection, the owner needs to
prepare the check list and tools related to the work they want to inspect.
Objective iv: Highlight Lessons learned
Below are some of the works owner needs to prevent and some works they
need to maintain and improve:
1. Prevent changes.
2. Prevent contractor to construct the work without site engineer’s
supervision
3. Prevent construction’s finishing stage in rainy season.
4. Prevent or reduce the construction works during studying time.
5. Prevent unrealistic duration for construction fixed by owner.
6. Provide the design brief and draft design as requirements of project’s
concept design.
7. Provide the furniture manual is required for project’s concept design.
The owner hired a professional foreign consultant company for concept design
and hired a local consultant company for basic and detailed design. This was a
good idea since it saved the design cost. However, the owner needs to manage
their communication with each other and control them accordingly.
8. The owner in-house project team was appointed as the project
management team. However, the allocation of team members should be more
sufficient since the personnel are trained properly to manage the construction
project.
Objective v: Develop a quality management system framework
The owner can use that QMSF for their future projects in term quality
approaching. After studying the above factors, the author found that the
problems related to communication, unclear requirements and unreasonable
schedule were the most common problems occurred in school project. And that was
also the main caused for project delayed and not good quality as well.
To support the theories in this study, the Quality Management in
Construction Project eBook was the main source for theoretical and management
tool to manage the quality in construction.
Besides some studies as mentioned above, the report still has some
limited and did not study clearly the following parts:
1. Financial source is the most important for construction project and it
affects directly to the quality of product.
2. How to manage the contractor and sub-contractors in term of quality
3. How to manage the quality of work in construction site
4. The applicability of the proposed solution in reality.
5. Managing the contract in terms of consultant and construction
6. The situation of this study is from the owner’s view. Thus, the study
just studies some factors related to the owner’s view only.
Recommendations
In general, to prevent problems occurred; the owner should follow some
recommendation as blow:
1. More careful in feasibility study
2. Clear
requirements from initial step of project.
3. Clear
consultant’s responsibilities and write down clearly their scope of works into
the contract.
4. Get user
involves in the beginning of project to prevent the changes and not usage. It
is a waste of time and money.
5. The owner is
developing more and more school projects. Thus, they should standardize all
school facilities, brand and design requirements from the design step to
handover step so that the quality of school project will be getting better and
better.
6. Try to manage
the time schedule and plans to avoid the unreasonable time schedule. It is one
of the major factors that affect the quality of project.
7. Applying the
tools to measure the quality of product.
Design process
1. Applying
quality management system framework
2. Applying
QA/QC for design process
3. In the tender
requirement, the owner needs to specify that the contractors’ proposals must
follow exactly 100% of the owner’s BOQ (including format, content and
specification). In case the contractor has some comments or further proposals,
they should put it in an appendix of proposal. The BOQ’s specification needs to
specify the materials, brands and sources of equipments. To study the
contractors’ proposals, the owner needs to have professional people who have
fully knowledge to check and compare the contractors’ proposals and make sure
the comparison is “Apple to Apple”.
Construction process
1. Applying Construction Quality Assessment System (CONQUAS) for quality
assessment.
2. Using QA/QC for construction process
3. Using some tool to measure quality as CONQUAS
4. Preparing and using check list for construction inspection.
5. Nowadays, almost people prefer has good quality for their project and
they have recognized that high quality and more investment will go together.
Thus, CONQUAS method will be used more in the future, because it is very useful
for quality assessment. Regarding to some of recommendation for construction
process, I would like to recommend that owner should use Quality Management
System Framework as proposed in Chapter 3 (please refer 3.8 of Chapter 3) for
whole project as standardize and consistent for their school system overall of
the world. Besides, Owner applies CONQUAS method for quality assessment
Abstract
In construction project, the scenario of
each project is not the same. Only if small thing goes wrong in construction
phase, nonconforming work is very difficult for us to repair or take remedial
action and in some cases it is impossible to get fixed. Furthermore, quality
management is affected by many elements such as manpower, technique, unforeseen
weather etc. Therefore, construction phase is very difficult to determine the
expected quality.
Besides, scope of the work, cost and
time of delivery are also important characteristics of quality. Quality in
construction project is not only the quality of product, technique and
equipment used in construction but the total management approach from the
beginning of project to completion stage. The quality of construction depends
mainly upon the control and monitor of construction, which are the primary
responsibilities of the contractor.
This report has been analysed based on a
real school project in Viet Nam and discussed clearly about project performance
from the beginning step to the very end. And then, it also proposes solutions
on how to get better performance for any cases especially school project.
Regarding to the practice process, the report has
also built the quality management system framework to serve as a management
model for developing school projects in Viet Nam.
