Based on the reports from the local media, most projects which
first applied in Vietnam and performed by Vietnamese organization were delayed,
had cost overrun or not financially vital due to lack of appropriate cost
management approach. Nguyen Sinh Khang made a case study which was expected to
provide the respective project owner especially the company which is performing
the first underground oil storage cavern project in Vietnam with sound cost management
approach. The objectives of the were to:
1. study the issues in cost management of construction
project especially of underground oil storage cavern project in Vietnam
2. provide recommendations on how the problems can be
managed and the frame work for owner’s project cost management approach
covering whole span of the project from pre-contact stage to post-contract
stage
Conclusions
For the project especially for the large-scale and complex
project like underground oil storage cavern, the cost overrun shall occur due
to three reasons such as: incomplete and inadequate drawings and specifications,
the Owner’s change to project requirements and changes from Contractor. In
spite of the efforts made by Owner, Owner’s Consultants and Contractors, there
are considerable factors that made cost overrun inevitable and numbers of the
factors are out of their responsibility and ability.
The followings are the Owner’s common factors that cause the
problem in cost management of the project:
1. Lack of management policy on report and control
practices;
2. Improper estimating techniques and/or standards leading
to impractical budget;
3. Fault sequence commencement and completion of activities
and/or events;
4. Unexpected material cost escalation;
5. Poor scope of work definition or inadequate WBS (Work
Breakdown Structure)
6. Selecting Contractor with the lowest tender price;
7. Improper planning system resulting in ineffective action
or cost;
8. Improper comparison of
actual cost and planned cost;
9. Unexpected and unplanned technical issues;
10. Delays and disruption resulting prolongation cost.
The conclusions of this study are as follows:
1. For Owner’s Cost management of pre-contract stage:
i. The Owner normally selects Consultant or Contractor who
proposes lowest bid regardless of experience, quality or expertise;
ii. Scope of work of Consultant or Contractor is poorly planned
and defined;
iii. Low accuracy is inherent in the approved cost estimate;
iv. Tight approved budget is included in the overall scheme;
v. Value engineering (VE) is not carried out during design
phases especially in the initial phase of the project.
2. For Owner’s procurement strategies:
i. Traditional method of procurement based on the clear
separation of design and construction is deployed.
ii. Price-based, lump-sum and specification contract in
which Contractor is required to estimate the quantities and subsequently to calculate
tender sum based on the owner’s drawings and specifications is deployed.
iii. Risk access is not carried out for decision making
especially in selection of project delivery system.
3. For Owner’s Cost management of post-contract stage:
i. Owner’s cost-management and
monitoring procedure lacks the following
characteristics:
ii. Cost is not forecasted before decision making ;
iii. Cost-recording system is not cost-effective to operate;
iv. Actual cost is not subject to variance analysis;
v. Time and quality do not implicate in the cost.
vi. Change management – Valuing variations:
vii. The proper recording system for changes is not
established and applied;
viii. Traditional method of valuing variation which is based
the valuation on the rates or prices specified in Bill of Quantity (BofQ) or
schedule. Normally, those rates or prices were quoted at the time of tender.
ix. Changes to the project arise due to:
a. Inadequate briefing from the owner;
b. Inconsistent and late instruction from the Owners;
c. Incomplete design;
d. Lack of careful planning at design stage;
e. Lack of coordination of specialist design work;
f. Late clarification of complex details;
x. Claim management:
xi. The delay claims on extension of time and cost of
prolongation from Contractor is not solved effectively and in amicable way.
xii. The Contractor often submits the claims due to the main
following reasons :
a. Inadequate time and planning before project commencement;
b. Inviting the tender on incomplete drawings;
c. Introducing extensive changes to the project;
d. Inadequate site investigation – deep basement; pilling,
earthwork, tunneling or unforeseen ground condition;
e. Extensive changes to contract standard form;
f. Owner’s inference with the timing and sequence of
construction.
Recommendation for management improvement
For the project with the similar condition as one in the
case study, the recommendations are as follows:
1. Value-for-money mechanism should be in place to evaluate
quality and price of the bid.
2. For any contract, the scope of work should be clearly
defined.
3. Proper methods with the different degree of accuracy for
each stage of the project shall be used.
4. The budget should be used positively to ensure that the
design stays within the scope of the original scheme.
5. The factors to be considered during cost estimate shall
be:
a. Land acquisition including
legal fees;
b. Owner’s organization cost
allocated to the project;
c. Site investigation;
d. Insurances;
e. Consultant’s fees including
engineering;
f. Equipment procurement and
installation;
g. Construction cost;
h.Taxes;
i. Contingencies and risks;
j. Financing and legal cost.
6. Comprehensive value management (VM) should be in place
all the time.
7. Design and Build shall be deployed.
8. Price-based bill of quantity (BofQ) with milestone
payments is applied.
9. Sound risk management procedures should be in place all
the time to access the risks so that unacceptable risks could be transferred to
relevant Contractor or Insurer by contractual commitment. Who-life costing
technique could be used where possible.
10. Costs should be forecasted before decisions are made to
allow consideration of all possible actions;
11. Cost-recording system should be simple and
cost-effective to operate;
12. Actual costs should be subject to variance analysis to
determine the reasons for any deviation leading to cost overrun;
13. The costs implication of time and quality should be
incorporated into the decision making process.
14. Parties should keep comprehensive and detail records of
the factors relevant to the variation.
15. Change consequences shall be mitigated by:
a. Setting up clear project
objectives;
b. Timely change instructions;
c. Practically-completed design;
d. Adequate planning at design
stage;
e. Adequate coordination of
specialist design work;
f. Timely clarification of
complex details.
16. The variation valuation procedure in which the parties
need to have skilled negotiation and be prepared to adopt a give-and-take
attitude in order to bring a satisfactory claim settlement.
17. Parties should keep comprehensive and detail records of
the factors relevant to the variation.
18. The variation valuation procedure in which the parties
need to have skilled negotiation and be prepared to adopt a give-and-take
attitude in order to bring a satisfactory claim settlement.
19. Owner’s project management team should be equipped with
knowledge of construction technology, construction law, term and conditions of
the contract, contract administration, project-planning system and negotiation
skill.
20. The following actions shall be required to avoid the
claims:
a. Adequate plan made by competent Owner’s engineer and/or
Consultant;
b. Availability of verified and completed drawings and
specifications prior to bid;
c. Minimize and eliminate the unnecessary changes to the
project;
d. Application of Value Engineering and/or Whole-life
Costing and/or Risk Access techniques to analysis the changes to project;
e. Comprehensive site investigation in which the scope of
site investigation shall be given by Consultant or Engineer who use site
investigation data for engineering works;
f. Usages of relevant contract standard form set forth by
recognized organization such as FIDIC, ICI ..etc.
g. Relevant Coordination procedure between Owner and
Contractor.
Abstract
As the same context of the projects which were first applied
technology, construction methods or project size in the developed countries,
the project of this kind or the likes in Vietnam cannot meet or exceed the
stakeholder expectations due to many unforeseen reasons.
The role of the organization performing project of this kind
of project is of great importance because its performance could bring the
success or failure to these projects. In Vietnam, the regular phenomenon is
that project planning and control of this kind of project is always under
expectation due to the lack of project management competence from the
organization performing project especially lack of appropriate cost management
approach. Those shall have bad consequences to the direct or indirect
stakeholders. Therefore, to be equipped with the most adaptable project
planning and control system for this kind of project is required by and from
the organization performing project and project team member also.
As mentioned above, the need of workable cost management
approach for the project of this kind is critical. This report shall therefore
address this development by underlining, prioritizing and specializing some
aspects of owner’s construction project cost management approach and shall give
some recommendations on or suggest some guidelines for this kind of project and
specific project as descriptions in case study.
