ESTIMATORS,
SCHEDULERS, AND COST ENGINEERS THEIR FUTURE ROLES IN PROJECT CONTROL
Gary B.
Gehrig |
INTRODUCTION
As
the economics of developing nations move further into the post-industrial era,
the human element of the "Work Force - Year 2000" plays an even more
important role in their progress and the competitiveness of the United States.
To continue to make a productive contribution to the cost effectiveness of the
economy, the amount of education and knowledge needed by the U.S. employee will
be greater. The U.S. Department of Labor predicts that for the first time in
history, the majority of the all new jobs will require post secondary education.
If
the U.S. economy is to grow rapidly and the American companies are to reassert
their world leadership, the educational standards in the nation's schools must
be raised dramatically.
Before
any projection can be made as to the future roles of the estimator, scheduler,
and cost.engineer, the industry in which they perform their duties should be
analyzed to determine the perceptions of the industry about the contribution
project controls makes in the construction process. Many experienced and
concerned constructors have contributed to this analysis and their assistance is
greatly appreciated.
CONSTRUCTION INDUSTRY FINDINGS ON
PROJECT CONTROL
Organization.
The
organizational structure of the company defines an orderly communication
network. The most efficient structure appears to be a strong matrix organization
with maximum authority being given to the project manager and less control being
assumed by the administrative manager. Companies are finding that a "Task
Force" organization with the project team being geographically located in
the same area has been very effective. Success of the task force depends on the
amount of responsibility and accountability each team member is assigned and
ultimately assumes. This organization gives the project manager the greatest
amount of authority, facilitates timely communication and builds team unity.
The
additional of an "Engineering Planner" to the engineering group
assigned to the team to act as a liaison between team departments has potential
for success. Engineers are more receptive to project controls because the
planner is one of them.
Progress Measurement
Engineering
progress has always been difficult to measure in that significant conceptual
engineering precedes calculations and drawings. Most engineering progress is now
mgasured by count of deliverable end items. Better control has been achieved by
adding progressing of procurement activities, modeling and cost/schedule
activities to project control. Studies have shown that drawings and
specifications constitutes about 55% of the engineering work and procurement
activities makes up about 25% of the engineering effort. Constructors have
developed effective procurement measuring systems tied to the work package
structure.
Schedules
Schedules
contribute to a good definition of the scope of work in the engineering,
procurement and construction phases of the project. The schedule gives something
to measure progress against. Effective scheduling control occurs when the
project team uses a hierarchy of schedule from level 1 to level 4, short
interval schedules and three week rolling schedules.
Project
Control System
Project
control systems typically used in the industry are designed as reporting tool
for management. The importance of timely information to the project team has
been largely overlooked. Many upper management people feel that field management
does not need to know job statistics. Japanese firms have taken a different
approach. They consistently push quality data down to the production level to
educate the work force, while American firms normally aggregate information
upwards in the organization.
Project
team members need data on a daily basis so that an accurate plan of action can
be made and problem ares can be dealt with while in the formative stage. A
project control system that helps is better accepted.
Project
control systems need to standardized on all projects within a company. The
tendency still prevails in the industry to permit the project manager to
organize the project to his system and desires.
Project
control systems are designed for large projects. The systems must be designed to
handle small projects efficiently.
CONSTRUCTION INDUSTRY INSTITUTE RESEARCH
Aerospace Industry
Versus Construction Industry
A
Construction Industry Institute (CII) research project investigated the
"New Frontiers" of project control in a study designed to uncover new
and experimental concepts of project control being used by CII member companies,
aerospace firms and computer companies. Because of the confidentiality of all
three industries, the researchers encountered many barriers to learning what is
in the future. In spite of the resistance, the following concepts were
identified.

Innovative Concepts
in Project Control
1.
Researchers found that Computer Aided Design and Drafting (CADD) is having a
significant spin-off effect on project control applications. Procurement
management systems, material management systems, computerized estimating systems
and design project control systems are being developed and tested in many
companies.
2.
CADD has the potential to adapt, to other project systems through the use of
object -oriented databases. A Line Item Status System (LISS) is an example of an
interactive database system used to track and status released work products. The
ability of CADD to capture quantities of materials allows CADD to become an
integral part of the control system in design as well as in construction. If a
project had an estimated 50000 cubic yards of concrete and the engineer had
designed 25000 cubic yards, the design of that activity would be 50% complete.
The potential for integrating a quality-based control system with CADD is
evident.
Software and Hardware
Vendors
1.
The current movement by the vendors is toward integrating small computers into
overall project management systems. The user friendly nature of small machines
has contributed to this movement. Small computers are becoming adept at
interfacing with the large main frames. This networking supports the team
approach and improves communication flow by allowing many people to access a
common data base. Computer vendors emphasize the hardware and software aspects
and integration; however, they do not consider the organizational or human
aspects of the construction industry.
Construction
Industry Institute Members The researchers found no evidence of an
organizational effort to advance the state of practice in either owner or
constructor companies. What effort that was being done was on small projects at
the project level. No-corporate programs to improve project management
techniques were identified. Most innovations appeared to be driven by an attempt
to adapt to the changing nature of the industry rather than an attempt to take
advantage of new technology.
MAJOR NEEDS AND TRENDS IN PROJECT CONTROL
1.
There is a need for less number crunching and more number analyzing. It was
found that more time is spent on gathering and processing data than on analyzing
data. Too much time is spent on measuring deliverable end items that constitute,
only 60 to 70 percent of the total project work. Project control needs to
measure the other 30 to 40 percent of the work. The need to build better
histories is evident.
2.
There is too much emphasis on the project control system and not enough on the
people using the system. People are the key to a successful project. The system
should be designed to provide information to the design engineers, estimators,
procurement, construction, etc. - not only to upper management.
Cross
training of the project team members in all disciplines on the team has
advantages. As each team member cycles through project controls, they learn of
the value of the system and better adapt it to their daily activities.
3.
Communication is a key factor in the effectiveness of project control. It
provides a frame work to develop a project plan and establish control by
assigning responsibilities to the right individuals at the right time.
4.
Include a measure of quality control in the project control process. Most
systems use only time and cost performance; however, cost , schedule, and
quality are also goals of the project. A quality performance index would
indicate both the frequency and severity of design errors and omissions and
would support the idea of quality at production levels. To accomplish the
measurement of quality a measure of quality or severity of nonconformance is
needed along with reasonable goals for quality. It is recognized that
institution hurdles and resistance to change must be over come to implement this
concept of quality control. The industry has not given much definition to this
concept, but it is appealing.
OWNER AND CONSTRUCTOR
VIEWS ON PROJECT CONTROLS.
To
determine the future roles of the estimators, schedulers and cost engineers, the
industry must turn to the current views of users of construction and to the
constructors. The CII study revealed the following views which need to be
studied for future research, training and implementation. This list is also a
summary of some of the major points of the previous discussion.
Organization
1.
A task force is the most common type of project organization. 2.
There is an increasing emphasis being place on educating project personnel
in project controls and on decentralizing project control groups. 3.
Project control systems are not designed to support the working level. 4.
Project managers control the support given to project control. 5.
Contractors are expending a similar amount of time and effort on project
control activities. 6.
"Up-front" planning is a major key to a successful project. 7.
Scheduling philosophy is similar but methodology varies. 8.
There is a decline in the value placed upon CPM scheduling. 9.
Progress measurement is similar but with different philosophy. 10.
Vendor data and vendor drawings are often a stumbling block to engineering
production and construction activities. 11.
There is a trend to controlling work by work packages or groups. 12.
Short interval scheduling is an effective tool to control schedules. 13.
Project control systems need to be designed to handle the small jobs as
well as the large ones and also need to be standardized. 14.
Small computers are the next, technological step in project control. 15.
Changes are the most troublesome aspects for project control. 16.
People - not systems - are the key to a successful project. 17.
The perception of the role to be played by the owner in project control is
similar but the application of the role varies dramatically. 18.
The amount of up-front planning and information provided by the owner in
the bid package differs dramatically from firm to firm. 19.
There is a trend to break projects into several smaller projects. 20.
Most owners concentrate on schedules but schedule requirements differ. 21.
The owner needs key people in project control to have a successful
project. |
PRESENT STATE OF THE
ART IN CII COST/SCHEDULE TASK FORCE COMPANIES
The
CII Cost/Schedule task force consists of 16 member whose corporate job titles
include Manager of Estimating, Manager of Project Controls, Manager of Planning
and Scheduling and Director of Construction Management. At a December 1988
meeting of the CII Cost/ Schedule task force the members were asked the
following questions.
1.
What kind of person will be needed in the future in project controls?
2.
What roles will the estimators, schedulers and cost engineers fill or play in
the future?
The
members of the task force recognized the increased competition coming from the
Japanese construction companies and. thought that any discussion of the future
should look at what the competition is doing to be successful. The Japanese are
goal oriented, they plan in detail, at the end of the day they plan for the next
day, and they involve the foreman in the planning. Quality control is critical
to their philosophy. The task force members concluded that the Japanese are
taking our concepts and using them. The American companies know about the
concepts but are not using them.
Bobby
McMakin stated that in foreign countries a initial entry person is expected to
work at the first line supervisor position before being brought into project
controls. One of the problems in our industry is that the college graduates all
want to be managers. They are not content to do initial entry work. Therefore,
future project control people must be more flexible and better trained.
Richard
Mayes suggested that future project control people will have to be more high
technology
literate. The use of computers is an absolute requirement. His company is not
looking for the one dimension specialist, but for the multi-talented
professional.
When
Jodie Caldwell assumed the position of Manager of Project Controls at Gilbert
Commonwealth, everyone was a specialist and the estimating and scheduling
functions were very centralized. All new hires into project controls are cross
trained in all aspects of project controls so that they can interrelate to the
needs and roles of the other team members. This training takes about 18 to 24
months to complete.
Dow
Chemical was using the cross training approach for all new hires according to
Stan Nethery. They had marginal success because his division did, not get a fair
share of the good trainees. After training the people moved to a new area of Dow
or left the company.
A
serious problem exists in the industry according to Jerry Davis and Tom Wilson.
The industry perceives estimators, planners and schedulers as second class
citizens. Jerry's biggest disappointment in his career as an estimator was not
being accepted as part of the team. He was never asked to attend meetings and
never part of the inter circle. Shell Oil Company is moving in the direction of
replacing employee estimators with contract estimators. Tom Wilson has seen
similar trends at ALCOA as the estimating department continues to shrink in
size.
Rust
Engineering ,has placed the cost engineer in the field where they feel he is
most effective. The cost engineer is part of the PM team and works closely with
the project manager. The project is subdivided in to accounts and the team is
responsible for the accounts. The cost engineer provides the PM with detailed
reports. and the rest of the team gets summary reports for their accounts. Only
about one third of the task force companies have their cost engineers in the
field.
General
comments of the task force members were recorded as listed below.

THE ESTIMATOR
The
estimator is one of the key players in a project control system and one
individual who will experience a major impact on his role from the changes
currently taking place in the industry. As researchers study the changing role
of the estimator, they need to simultaneously study the other players on the
team. However, before we start writing a new job description of the team, it is
important to review the definition of an estimator and keep a perspective of the
central role of the estimator in the process. The following is abstracted from a
description of "The Estimator" as published in the Journal of the
American Society of Professional Estimators.
"The
estimator must be able to visualize what is not apparent, and for this he
requires imagination. He must be able to think in abstract terms. He translates
graphic and verbal information into probable costs in the light of experience.
This is not a direct and mechanical process; it is creative and demands a high
level of concentration and mental effort. Estimating requires common sense and
an ability to work for a goal that is not always achieved."
Attempts
have been made in the past to model the estimating process and construction
costs. These models used the techniques such as multiple linear regression
analysis and other statistical methods to predict constructor costs. Such models
failed in their development because they did not take into account the skill of
the estimator. The present attitude is that the estimating process is a
combination of data, technique, calculation, analysis and judgement. It is a
combination of the mechanical process coupled with aspects of professional
judgement. Because the judgement factor is very subjective and the judgement
process is not well understood, it will be difficult to transfer the judgement
to an expert system or other computer system.
The
use of the computer has been a tremendous facilitator in the estimating process.
It has removed much of the drudgery work and allowed the estimator time to do
thorough estimate reviews.
Where
is the threat to the estimator and other player son the team? There is no doubt
that expert systems will impact the profession. Can it be used to benefit the
project control profession rather than replace it? Some proponents feel that
expert systems will provide the client with the estimating expertise needed to
conduct business. Others believe that computers will have difficulty duplicating
the creativity of the estimator.
The
estimator has already responded to the changes brought on by the contractual
arrangements and cost engineering systems. The profession has seen estimating
departments getting smaller and in many cases, disappearing. But the individual
estimator will be around for the foreseeable future. To do this, the estimator
must be more creative and flexible. They will need to be experts in detailed
analysis and forecasting of resources. They must be knowledgeable and prepared
to provide input at all phases of the project. They will need to understand the
money aspects of their company. In short, estimators must gain the skills to be
fully functioning middle managers in the construction industry.
CONCLUSION
Cost
effectiveness in the construction industry calls for the purposeful and
intelligent application of conventional wisdom, for using good new ideas
whatever their source and for developing and applying basic new ways of thinking
about construction. The cost effectiveness can be controlled and major savings
achieved If top management gives it the same attention and direction applied to
production, marketing and other mainstream functions.
Future
construction cost effectiveness depends on the people, their training,
upgrading, supervision, motivation, involvement, commitment, the proper use of
their skills and the practices and conditions that control the performance of
their job. The future roles of the estimator, scheduler, and cost engineer
depend on the direction the construction industry takes in these changing times.
Unfortunately, the industry has not clearly defined it's goals and objectives
for the next decade and continues to be a reactive industry. Therefore, the
roles of the team players will continue to determined by reaction to outside
forces on the industry.
