for Integrated Cost and Schedule Performance Control
Youngsoo Jung, A.M.ASCE1; and Seunghee Kang2
Abstract: Though the progress of construction projects is most often used as a critical index for effective project management, the
method, structure, data, and accuracy of detailed progress measurement may vary depending on specific characteristics of a project. This
situation can lead to misinterpretation of the project status, especially under a multiproject management environment. It is also a daunting
task for the inexperienced engineers to formulate and monitor the project-specific work packages. At the same time, maintaining very
detailed and highly accurate progress information requires excessive managerial efforts. In order to address this issue, this study proposes
the concept of standard progress measurement package. Issues for standardization of the work breakdown structure that can embody
distinct characteristics of different construction projects are investigated. The proposed methodology facilitates automated formulating of
work packages by using a historical database and also automates the gathering of progress information through the use of standardized
methods and tools. A case-study project is evaluated in order to examine the practicability of the proposed system.

Cost, schedule, and quality are the three major indicators for construction project performance. Accordingly, integration of cost
and schedule control systems has been an issue of great concern
for researchers and practitioners as these two important control
systems are closely interrelated, sharing numerous common data
?Rasdorf and Abudayyeh 1991; Jung and Gibson 1999; Jung and
Woo 2004? in their controlling processes.
In recent efforts to systemize construction management
processes, standard methods and procedures coupled with information technology have been widely adapted. The earned value
management system ?EVMS?, which integrates cost and schedule
control, is a good example. Two important features of EVMS are
the combination of two different construction business functions
?i.e., cost and schedule? into a unified perspective and the provision of highly detailed standard methods and procedures so as to
compulsorily maintain data integrity among many different
project participants ?Jung and Woo 2001?.
The progress ?or earned value? is key information in the integrated cost and schedule control as it provides a baseline for
comparison with the planned schedule and/or actual costs. However, the method, structure, data, and accuracy of detailed

progress measurements may vary depending on the characteristics
of a project, organization, or location. Regardless of the variation
in the methods utilized, in terms of accuracy, ideally the progress
data should be analyzed and maintained in a highly detailed form.
Nevertheless, the excessive workload required to manipulate very
detailed progress data is also a critical issue ?Deng and Hung
1998; Rasdorf and Abudayyeh 1991; Jung and Woo 2004? for
effective cost and schedule control.
No previous research or professional practice has comprehensively addressed the issues of standard progress measurement
methodology in terms of its practicability, accuracy, efficiency,
and potentiality for automation. In this context, the purpose of
this study is to develop an effective progress measurement system
utilizing standard progress measurement packages ?SPMPs?, as
depicted in Fig. 1. A prime objective of developing SPMPs is to
identify manageable work packages with reliable progress measurement ?enhancing accuracy?.
Even though those are not addressed in detail, this study also
discusses applying standard measures and procedures to as many
projects as possible so as to attain a corporate-wide index ?making
standards?, facilitating the process of work breakdown structure
?WBS? formulation by using a prestructured historical database
?alleviating workload?, and accommodating self-evolving features
of standard packages by analyzing the changes of managerial
policy under an ever-changing business environment ?sustaining
A case study is used throughout this paper in order to illustrate
and examine the proposed methodology. The case-project is a
research center constructed by a case-company. The research center is basically comprised of an eleven-story office building ?two
stories underground and nine stories above ground? and a laboratory. Specifics of the project include: 17,087 m2 of total floor
area, 19-month project duration. A general contractor’s viewpoint
as a case-company is applied in this case-study, and the architectural work alone is analyzed excluding earthwork, mechanical,

and electrical. Details of the case-project are summarized in
Table 1.
Progress Measurement in Construction
By definition, “progress” refers to the “advance toward a specific
end.” The degree of “advance” for a construction project can be
determined in many different ways. In their study for measuring
construction productivity, Thomas and Mathews ?1986? assert
that the “progress in terms of work unit completed” and “the
associated cost in terms of man-hours or dollars” are typically
tracked in order to measure productivity. For the purpose of construction payment, progress can be explained as the “percentages
of direct cost incurred plus a portion of overhead and profit”
?Stokes 1978?. From the viewpoints of cost engineers or scheduling engineers, somewhat different considerations for progress
may also be inferred.
Nevertheless, the most commonly perceived concept of
progress implies the “work completed” and the “associated cost.”
Therefore, progress in this study is defined as the “actual work
completed in terms of budgeted cost.” This definition is identical
to the meaning of “earned value,” or budgeted cost for work
performed ?BCWP? in EVMS.
Progress in Earned Value Management
Benefits from integrating cost and schedule control ?EVMS? have
been asserted by numerous researchers and practitioners since this
idea was first promoted in the 1960s. The basic concept utilizes
the focal point for the integration of scope, cost, and scheduling
?Rasdorf and Abudayyeh 1991; Fleming and Koppleman 1996?.
According to a document of the American National Standard
Institute ?ANSI? for EVMS, a “control account” ?CA? as the focal
point acts for “a management control point at which budgets and
actual costs are accumulated and compared to earned value for
management control purposes” ?EIA 1998?.
The progress ?earned value, or BCWP? is used as a baseline to
which the planned schedule ?budgeted cost for work scheduled,
BCWS? and the actual cost ?actual cost of work performed,
ACWP? are compared in order to measure the schedule
performance and cost performance, respectively. The results of
performance variances and indices are used for further analysis,
including estimating cost at completion, identifying latent risks,
and replanning for remaining work packages.
The level of progress measurement packages is a critical issue
in terms of the “workload” ?i.e., manageability? required to maintain the control system and the “accuracy” of the packages ?Jung
et al. 2001?. In other words, it is ideal if very detailed progress
data can be gathered and analyzed for any project. However, this
situation may require an excess of managerial effort with limited
usage of the data. At the same time, it is very likely that less
detailed packages would provide more inaccurate information. In
order to address this issue, the level of detail for progress measurement should be carefully selected as a trade-off between the
workload and accuracy, incorporating strategy, objectives, and
management policy of construction projects.
Progress Measurement Workload
The most significant part of workload is collecting and maintaining data that is generated throughout the project life cycle. In
particular, EVMS requires more complex data structures and additional management efforts as it integrates two different aspects
of business functions ?cost and schedule?.
Therefore, optimizing ?or minimizing? the workload is the
critical success factor for practical implementation. This optimization can be achieved ?1? by automating data acquisition; ?2? by
reengineering the cost and scheduling control processes; and/or
?3? by adjusting the level of details ?Jung 2005?.
Automating data acquisition can be obtained by applying such
data acquisition technologies as RFID, GPS, or 3D laser scanning
?Navon 2005? or by electronically interconnecting databases from
relevant business functions ?e.g., material management or daily
work report?. However, utilizing IT is less specific to a project or
a company. Rather, it is industry-specific, as similar tools and
methods can be generally applicable to any type of project ?P1 in
Fig. 1?. On the contrary, the scheme of reengineering varies extensively depending on the organization ?Jung et al. 2000?. Practical solutions are very different for each company, as they are
organization-specific ?P2 in Fig. 1?. Finally, adjusting the level of
detail is a project-specific issue ?P3 in Fig. 1?. Basically, the level
of detail is determined by the managerial requirements of each
project. However, common characteristics within the same type of
facilities in a company can be identified in order to effectively
utilize the standardized methods.
The three schemes discussed previously should be deliberated
in a comprehensive manner, because they complement each other.
However, this paper focuses on “adjusting the level of details” by
using standardized progress measurement packages that can alleviate the workload for initial WBS formulation ?planning?, data
entries ?controlling?, and historical data retrieval ?reusing?. This
usage is depicted as U1, U2, and U3 in Fig. 1.
Progress Measurement Accuracy
Several different progress measurement methods are developed
and used in construction projects. Definitions and classifications
may vary slightly. This study utilizes three major types of measurement methods categorized by Thomas and Mathews ?1986?:
estimated percent complete method, earned value method, and
physical measurement method. As listed in Table 2, each method
has strengths and weaknesses.
Among these three measurement methods, the earned value
method may utilize various techniques for different type of work
packages. Fleming and Koppleman ?1996? specify seven techniques including percent complete estimate, weighted milestones,
fixed formula by task, percent complete and milestone gates,
earned standards, apportioned relationships to discrete work, and
level of effort. Note that Fleming and Koppleman categorize “percent complete estimate” as one of the earned value techniques
whereas Thomas and Mathews ?1986? separate it, as described in
Table 2.
Standards Making
Standardization of WBS or CA seems extremely difficult in practice, because each construction project is unique and has different
managerial requirements. However, this standardization would
significantly contribute to reduce the workload and enhance the
accuracy of the progress measurement if properly applied.
In their research exploring a process model of standardization
in the information and communication technology ?ICT? industry,
Fomin et al. ?2003? define three recursive activities of “design
?creating and choosing design alternatives?, sense-making ?attach-

ing meaning to design alternatives?, and negotiation ?agreeing between designs, fixing the actor network?,” which can be a good
point of departure for construction WBS standardization.
Managerial similarity within a specific type of construction
project ?e.g., office buildings? or within a company makes it
possible to develop reasonable standard progress measurement
packages ?“design”?. An ever-changing business environment and
construction technology may require seamless modification of the
standards ?“sense-making”?. Finally, the standards must incorporate conflicting interests between different projects and different
actors ?“negotiation”?. Again, conflicting interests simultaneously
occur between the workload and accuracy in terms of
Standard Progress Measurement Package
In order to incorporate different interests ?the workload, accuracy,
and standards issues discussed previously?, the SPMP proposed in
this study pursues corporate-wide standard packages which are
self-evolving. Major features of the proposed methodology are
illustrated in the following, and the conceptual components are
depicted in Fig. 2 and Table 3.
Alleviating Workload
A work package or a CA is typically composed of two major
properties ?e.g., first-floor concrete work?; one is the classification
of commodity breakdown ?budget accounts?, and the other is arrangement of physical breakdown ?locators, e.g., facility, space,
or element?. Therefore, a small increase in the number of CAs or
budget accounts ?BAs? under integrated control systems can
cause enormous expansion of workloads. In addition, physical
breakdown is generally more project specific than commodity
breakdown ?Jung and Woo 2004?.
In order to effectively address this issue, this paper defines a
progress measurement package ?PMP? as “a major work package
composed of assigned budget accounts.” A PMP with a physical
breakdown ?a locator? is then defined as a “PMP activity,” which
is used as an activity for the CPM schedule or as a CA for EVMS.
For example, a commodity group of budget accounts ?e.g., concrete, reinforcing bars, and forms? constitutes a PMP ?e.g., con-

from the predefined standard PMPs in order to reduce the workload. A flexible WBS concept ?Jung and Woo 2004? is adopted to

widely adapted in the case-study.
