Abstract
Normally, completion
project within requirements about time, cost and quality is the major targets
of every projects. Construction timely can be regarded is one of three critical
factors to evaluate the success of construction project. The construction
project can not considered successfully if it was not on time and delay.
However, almost of construction project in Vietnam have face with this problem.
In these current years, Vietnamese construction industry has seen an alarming
increase in delay. Especially in high-rise building project, this problem has
become one of the most serious problems.
The study is
conducted by using quantitative research. The survey of this study was
implemented in three big cities in Vietnam – Ho Chi Minh, Can Tho and Hue city.
Firstly, the main purpose of this study is identified the important causes lead
to the delays in high-rise building project in Vietnam. After that, this study
will find the correlation between causes and effects of delay to evaluate the
impact of delays causes to project. Moreover, another purpose of this study is
finding the successful factor, which can be applied to avoid and minimize delay
in high-rise building projects.
Executive summary
Rationale
of research
This research has been conducted to study delay issues in High –rise
building construction projects in Vietnam.
Objectives
of study
To
study the causes of delays in building construction project in Vietnam and the
effects of delays in high-rise building projects to suggest successful factors
that can be applied to avoid and minimize delays in high-rise building project
in Vietnam.
Methodology
The
framework of methodology is to investigate activities of project which are
designed by questionnaires that are performed by project managements teams of
owner, construction and consultant companies in Vietnam. Methods concern the
techniques which are available (for data collection, analysis method, etc.) and
those which are actually in use in a research project. In general, plan will
assure that the process base on features of literature review and the
objectives of study.
Findings
and conclusion
This time, construction delay is the serious problems
for Vietnamese construction industry. Especially in high-rise building projects
in Vietnam, they have seen an alarming increase in delay problem. There are
many efforts, which are underway to resolve this problem. However, this problem
in Vietnam is still serious. It is not only popular but also its effects are
high severity. Thus, a study about delays in high-rise building project in
Vietnam is necessary. The finding of this study will be summarized below.
Causes
of delays in high-rise building project in Vietnam
Firstly, three
ranking by three main parties of project was conduct to find out the important
causes of delays based on the view of three groups. The results of these
ranking were used, According to result, these correlation is strong at 0.01
significant level, that means there are 99% confident that the viewpoint of
three main parties about delay causes are highly agreement.
Because of the
agreement among three main parties, the ranking based on all respondents, who
come from three main parties will be acceptable.
Top ten of delay
causes, which have high frequency of occurrence are: (1) Rising price of
material, (2) Financial problem of owner, (3) Lack of high technology
equipment, (5) Payment problem, (6) Unskilled workers, (7) Financial problem of
contractor, (8) Change others by owner, (8) Lack of capability of contractor,
(10) Lack of detail and unclear information in drawing and design document.
Ten most severity
causes of delay including: (1) Rising price of material, (2) Lack of capability
of contractor, (3) poor experience of contractor, (4) Financial problems of
owner, (5) Financial problems of contractor, (6) Improper construction method
implemented by contractor, (7) Insufficient data collection and survey before
design, (8) Unskilled workers, (9) Lack of labor, (10) Delay work caused by
subcontractor.
The important causes
of delay were identified by important index, which was accounted based on the
frequency and severity of each cause in the list of delay causes. According to
the result of this study, top ten of important causes of delay in high-rise
building in Vietnam are: (1) Rising price of material, (2) Financial problem of
owner, (3) Contractor lack of capability, (4) Financial problem of contractor,
(5) Delays work caused by subcontractor, (6) Unskilled worker, (7) Contractor
poor experience, (8) Delay payment problem, (9) owner change orders, (10)
Slowness decision making.
Effects of delays in high-rise
building project in Vietnam.
Almost
groups of causes have correlation with six effects of delay. All most the
relationship between causes and effects of delay are the moderate correlations
(the correlation coefficient from 0.3 to 0.7). However, the causes that created
by the special character of project are not related with effects of delay. All
correlation between this group with effects of delay is weak (correlation
coefficient is lower than 0.3). Groups of causes, which created by owner and
contractor, are the causes have strongest correlation with effect of delays.

Avoid and minimize delays in
high-rise building project in Vietnam.
In
these current years, Vietnamese construction industry has seen an alarming
increase in delays in construction projects. Especially in high-rise building
project, this problem is more general and serious. Therefore, finding the way
to avoid and minimize delays in high-rise building is a necessary mission, and
many efforts are underway to find the solution. In this study, one of major
purposes is find out the important factor, which can be applied to avoid and
minimize delay According to the results, tops ten important factors can apply
to avoid and minimize delays in high-rise building project in Vietnam are: (1) Ensure adequate and available source of finance until
project completion, (2) Competent project manager, (3) Selection of a competent
and reliable consultant to carry out the work, (4) Comprehensive contract
documentation, (5) Perform a preconstruction planning of project tasks and
resource needs, (6) Frequent progress meeting, (7) Adopting a new approach to
contract award procedure by giving less weight to prices and more weight to the
capabilities and past performance of contractors, (8) Contingency plan, (9)
Multidisciplinary/competent project team, (10) Ensure timely delivery of
materials.
