CONSTRUCTION
SUBCONTRACTING AS AN EDUCATIONAL TOPIC
John Mouton and Hal Johnston California Polytechnic State University San
Luis Obispo, California |
The
evolution of subcontracting has had a substantial impact on the
construction process. An increasing portion of building construction
projects are contracted to specialty, trade contractors. As a group,
subcontractors contribute significantly to the capital risk, resources,
managerial effort, and business expertise supporting the largest
industry in the country. Collegiate construction programs should address subcontracting issues to increase the awareness of students to the impact of and opportunities in subcontracting. The reference material used in
most courses is oriented to the general contracting sector without
explanation of key operational and managerial differences found in
subcontracting. A prime example is emphasis on project management
considerations (ie., scheduling) as compared to multi-project management
methodology. The paper addresses the
opportunity to include subcontract management topics in existing courses
in lieu of establishing a separate course. Key Words: Specialty
Contractors Subcontractors, Multi-Project Management, General
Contractor-Subcontractor Relations, Curriculum
Planning Course Development |
As
construction educators, there are four specific questions to be answered in
regard to Construction Subcontracting as an Educational Topic.
First:
Is subcontracting a significant factor in the building industry?
Second:
Do management techniques and decision processes in speciality subcontracting
differ from those applied in general contracting?
Third:
How do General Contractor - Subcontractor relations influence the success of bid
proposals, project time and quality, and the associated project risks?
Fourth:
Are these topics given adequate attention in the current curriculum and courses?
The
intent of this paper is to provide a summary statement to facilitate the
reader's answers to the first three questions and to suggest opportunities to
develop an appropriate curriculum response to the fourth.
EVOLUTION
OF SUBCONTRACTING
A
review of the evolution of speciality subcontracting sheds light on many current
issues. If there was an original impetus to subcontracting, it was the movement
from generalized to specialized construction craft trades. With the anticipated
improvement in worker skill, productivity, and product quality came the complex
question of effective and cost efficient utilization of these speciality skilled
craftsmen.
Given
the apparent and actual improbability that a General Contractor would sustain an
adequate amount of specific skilled craft work (eg., painting, masonry) on a
year-round basis, the more skilled workmen found better opportunities with
companies that specialized in their specific work area. The trend toward more
subcontracted work accelerated as the technical development of building
materials and methods escalated the requirement for craft skill and knowledge.
Quality control and labor management problems on construction projects became
less complicated for general contractors utilizing specialty trade
subcontractors in lieu fo furnishing all craft labor themselves.
A
cause and effect of this evolution has been a redistribution of the project
risk. Utilizing a subcontract bid and resulting contract, the General Contractor
fixes the cost of an in-place segment of work at the time of the project buy-out
with the specialty subcontractor responsible for cost overruns.
One
indication of the influence of subcontracting is to look at the cost breakdown
of typical building projects. While some Construction Management and General
Construction firms do subcontract 100% of the technical trade work, the
subcontracted amount seldom decreases below 50%. Depending on the type and
complexity of the project and the capability of the General Contractor, the
subcontracted portion of the total contract (including general conditions and
contractors fee) is typically 65% to 80%. The size and volume of these firms has
also increased. They now rank with the largest building contractors (Figure 1.)
and as a segment of the industry, they have larger volumes and numbers of
employee than many of the "General" catagories. (Table 1.)
Table

listing of top specialty subcontractors, when compared to their listing of
top building contractors, indicates that at least the top three in each category
(Mechanical, Electrical, Structural Steel, Etc.) had an annual contract
volume that would have placed them in the top fifty list of the building
contractors. |
PROFILE
OF SPECIALTY CONTRACTORS:
As
a general rule, students view their future role in the construction industry as
that of General Contractor or Construction Manager. This perception is , of
course, fostered by the predominance of General Contracting firms involved in
on-campus employment recruiting, the slant of many of the text and course
reference materials, the support of particular industry associations, and the
prior experience of many faculty.
A
potential conclusion could be that many students do not recognize the
significant role of speciality contractors nor the the explicit differences in
managerial style and application required of those subcontractors. In many
instances, they are also unaware of the tremendous opportunities that exist for
graduate constructors in specialty construction areas.
The
management of resources and project coordination efforts for most specialty
subcontractors are significantly different than the comparable tasks in a
General Contractor's operation. Many specialty contractors will contract
directly with Owner on a single contract basis or as one of a number of multiple
prime contractors on a given project. These relationships result in different
methods of project coordination and interface. The specialty contractor must
respond to these differences engaging in a role that combines the managerial
characteristics of the typical General Contractor and the typical Subcontractor.
Manpower
utilization and distribution over a number of projects is a dynamic problem for
specialty subcontractor managers. Their potential for solutions differ greatly
from the resource management alternatives available to a General Contractor. A
well prepared Specialty Subcontractor's project manager will anticipate problems
and potential conflicts and supply appropriate managerial and technical
experience in a pro-active manner to assure the performance of others upon whom
he or she relies. As an example advanced analysis of the actual project
status/project progress provides the forward looking specialty contractor,
multi-project manager with a reliable source of information for company wide
resource planning, allocation and control.
The
Subcontractor's procurement and management of material and equipment involves
the collection and preparation of a number of submittals that must be processed
through the General Contractor and Architect/Engineer's organizations prior to
order. The contractual relationship may inhibit the Specialty Subcontractor's
leverage in this process. Attentive, well educated subcontractor project
managers will enhance their firm's managerial position by requesting, receiving,
and documenting submittal procedure process and approval time commitments at the
pre-construction conference. A missed opportunity can have detrimental results
impacting the Subcontractor's project schedule and profitability.
It
might be beneficial to consider some of the project coordination issues facing a
mechanical project manager. Often, their work includes second tier
subcontractors (eg., ductwork, controls); writing and managing of specific
performance contracts is essential. Crews are often cycle on then off the
project. As an example,
the plumber will complete the under-slab and site piping later returning for the
above slab rough-in and finally returning to install fixtures and trim out. Of
course, demands on other projects often necessitate that the individual phases
will be accomplished by different crews resulting in increased coordination
problems including completion of as-built drawings. Labor leveling is complex if
achievable.
Code
issues and inspection requirements are other areas of concern for the
subcontractor's project manager. The performance specification often establishes
acceptance as operational success which is not determined until the final days
of the project. Problems are frequent and response time limited. Prior planning
and appropriate resource allocation are essential to satisfactory project
completion.
Equipment
procurement involves a number of suppliers relying on a multitude of submittals.
Given that crews work mostly with small pieces and small tools, the handling and
setting of major equipment is complex in that it is short in duration with a .
significant resource demand.
The
Subcontractor's typical source of work is the General Contractors that assume
responsibility for complete construction of the project. At any point in time,
the subcontractor is providing specialty construction services to a number of
General Contractors with varying expertise in subcontract development,
subcontractor management and relations; project management, coordination, and
control; and project cash-flow reliability. Additionally, a regional
Subcontractor will repeatedly, and often on simultaneous projects, contract with
the same General Contractor. Decisions on individual projects are often
influenced by the objective of sustaining an on-going relationship. Both the
short-term (project) and long-term (future contracts) relationships with the
General Contractors are essential to the success of all specialty
subcontractors.
It
could be observed that the Specialty Subcontractor has less control of his/her
own destiny than does the General Contractor, but that need not be true. These
and a large number of other issues occurring on a number of simultaneous
projects with fluctuating schedules and various managerial approaches is a
complex arena in which the prepared Subcontract project manager achieve success
and the ill-prepared struggle to survive.
GENERAL
CONTRACTOR-SUBCONTRACTOR RELATIONS
Construction
Claims Monthly states "No issues are of broader concern to the construction
industry than the issues arising out the relationship between prime contractors
and their subcontractors." [1]
In
education, we include significant depth and breadth of coverage of the General
Contractor-Owner relationship, Architect-General Contractor relationship, labor
relations, and organizational behavior with less than complete address of the
significant issues in General Contractor-Subcontractor Relations. As General
Contractors, our alumni are dependent upon their subcontractors for the
successful completion of their projects. It is a certainty that the project
personnel have far more involvement with, and their success will be more
dependent upon, the Specialty Subcontractors that with the Owner, Architect, or
labor groups.
Negotiations
between the General Contractor and Subcontractor are ongoing throughout the
duration of the project. Issues include job staffing, sequence of work, quality
and quantity of work in place, interface with other work, schedules and progress
projections, progress payments, and change management. Successful negotiators
are knowledgeable and ever aware of the other sides' needs, desires,
requirements, and position. The General Contractor who understands the technical
and managerial problems of the Specialty Contractor is in a position to motivate
as well as respond to the true needs of the subcontractor resulting in an
increased probability of meeting the critical responsibility of delivering a
quality project on time.
Major
specialty contractor associations identify prompt payment, actually lack
thereof, as the principle problem faced by subcontractors. Bid shopping and
ineffective change management resulting in non-compensatable extra work are also
major concerns. The managerial opportunities and ethical issues involved in
these critical General Contractor-Subcontractor relationship factors should not
be ignored in the education and training of the future industry leaders.
"Unless
the subcontract states otherwise, the prime contractor has a duty to schedule
work so that subcontractors will no be delayed in the performance of their work
or forced to perform work out of
sequence" [2] Delay and disruption claims by subcontractors are increasing
and courts, experienced through contractor's delay claims against owners are
validating the specialty contractors claims.
Many
specialty contractors (eg. finishing trades ) continually find themselves in an
acceleration mode on a number of their projects. The cost (overtime) impact
and/or quality issues (larger crews with less skilled craftsman) of acceleration
can be damaging to both reputation and profitability. While it is not always
possible to bid the anticipated overtime or acceleration and be competitive, it
is possible for subcontractors to favor general contractors with better managed
projects when bidding. This consideration is recognized by specialty and general
contractors alike.
The
student or graduate who perceives the answer to technical and managerial
questions to be "we'll subcontract that", has not been adequately
prepared. Subcontracting work without understanding the technical aspects and
coordination implications places ones destiny in the hands of others. In
technical and managerial courses, the potential problems and anticipated
position(s) of the subcontractor can and should be included as a foundation for
the future success of the student(s).
SUBCONTRACTING
TOPICS IN EXISTING COURSES
Well
established collegiate construction programs often experience difficulty in
attempting to incorporate additional course work in the curriculum. Given
general education requirements, the limited number of elective courses, and the
breadth of construction topics considered essential, the consideration to add a
new course must answer the question: what can/will be eliminated?
The
authors of this paper anticipate that curriculum planners and construction
educators will find it more expedient and potentially more effective to expand
current course coverage to include subcontract issues in lieu of concentrating
that information into a single new course. It is recommended that a subcontract
topic outline be developed and compared to existing course content. The topics
can then be assigned on a programmatic basis expanding the student's preparation
to engage in the complexity of Subcontractor -General Contractor relations.
The
following suggestions are based on topical rather than course breakdown in an
attempt to facilitate curriculum planning and
development
given the individual construction programs course strategy.
Technical
Courses:
Given
that many of the technical areas of project execution are typically
subcontracted, courses that address those topics can easily and appropriately
include subcontract issues. Most construction curriculum separate the building
systems, including Plumbing, H.V.A.C., and Electrical, into a course series. The
courses are often classified as technical emphasizing design and operational
topics while ignoring the subcontractor's project coordination issues and
installation methods. The courses should include a focus on the materials,
methods, sequence, and technical interface phase.
These
systems and other (i.e. , curtainwall, roofing) subcontracted items have a
substantial impact on the initial and life-cycle cost of the project. Value
engineering applications and constructability studies that are technically based
and economically derived can be included; the students will develop a relevant
decision process that will serve their professional needs as a negotiating
conduit between the Owner's Architect/Engineer and the Specialty Subcontractor.
The
technical execution of the specialty work will always interface with other work
performed by both the General Contractor and other Subcontractors. The
discussion of required methods provides an ideal opportunity to address schedule
interface from a sequence, duration, and resource allocation standpoint.
Projects
developed in each course should be expanded beyond the typical technical
design-operation questions to include cost and resources estimates, schedules
with crew durations identifying potential pre-assembly work, and scope of work
(for contracts) statements.
Project
Management Courses
The
management of building construction projects includes the management of
subcontracted work by the General Contractor and the management of individual
areas of work by the Specialty Subcontractor. The managerial success of the
project is, to a large degree, dependent on the interface and abilities of a
multitude of managerial decisions executed by and influencing a number of
managers. Coordination of these effort are key elements to be considered in
construction education.
Simulations
and case studies are often included in project management courses. These
educational methods provide a prime opportunity to include subcontract
management problems. Role playing on both sides allow the students to experience
some of the complexity the actual relationship that exists between the
subcontractor and the general contractor.
Change
management and the impact of Owner-Contractor and Contractor-Subcontractor
contract terms and conditions are important considerations in project
management. Likewise the progress payments application and payment distribution
process is critical to a successful General Contractor-Subcontractor
relationship.
In
subcontracting, resource allocation and scheduling is usually a multi-project
task. Likewise, many project managers in General Contracting and Construction
Management firms are involved in multiple projects. Problems developed for
single project application (eg. schedule crashing) can and should be expanded in
scope and complexity address the a specialty subcontractors position on a
multiple project basis. The role of the specialty contractor's project manager
should be one focus of the project management course.
A
well-rounded student will realize the interdisciplinary nature of the industry
and recognize the benefit of a comprehensive understanding of the skills,
abilities and perception required to succeed in speciality subcontracting. It is
valid and valuable to include Specialty Subcontractor project and multi-project
management topic in addition to coverage of the General Contractor's management
of Specialty Subcontractors. Understanding the concerns and methods of the
Subcontractor's project manager will enhance the success of all future builders.
Scheduling Courses
An
examination of the content of a scheduling course might reveal that the
subcontract activities are viewed as a given. Other than mention of the
subcontractor's participation in the development of the schedule and the
necessity for crashing subcontract activities, the scheduling and time
management issues regarding subcontracting are often ignored.
A
review of a realistic construction schedule will reveal both critical and
low-float subcontract activities. There is no doubt that the subcontractors will
influence the project time management. Likewise, the schedule creates certain
obligations on the part of the General Contractor to the Subcontractor. This
topic should receive adequate attention. "The prime contractor has a duty
to schedule work so that the subcontractors will not be delayed in the
performance of their work or forced to perform work out of sequence." [3]
The
scheduling of subcontracted work is essential in establishing an accurate,
accomplishable schedule. While the sequence of the activities may appear
obvious, there are often many factors in specialty contracted work that
substantially impact the project that are not obvious to the casual observer.
The duration estimates for subcontracted activities are critical. The scope of
the work and manpower requirements must be clear and the subcontractor must
commit to furnish the resources when required if the project schedule is to
succeed.
In
many circumstances, the Prime Subcontractor's work is scheduled as a single
activity. Many bar chart show no indication of the impact of key subcontract
work items on other activities or project milestones. Schedule slippage analysis
and/or acceleration decisions must address the total impact on the time and cost
parameters of the project; incomplete planning information will result in
incomplete decisions.
A
schedule that includes the true relationship of subcontract work item activities
to other project activities will facilitate project decisions that will be both
timely and accurate. Required tests and inspections, including subcontracted
work, should be milestones in schedule development. Schedule analysis exercises
should include subcontract activity evaluation.
An
exercise in multi-project labor leveling will provide the students with a
firsthand experience of the resource problems faced by a Specialty
Subcontractor. Material management of long lead items usually involve
subcontractors and can be included in the labor leveling problems to increase
the complexity. In any event, actual manhour requirements for key subcontract
activities and standard crew sizes should be used in duration estimate
exercises.
Scheduling
courses that utilize computer applications can easily accommodate the proposed
exercises. As the computer has become the standard and very useful tool in the
scheduling process, it has also implied a standard for resolution of disputes.
"The widespread use of computerized scheduling techniques has provided new
opportunities in project management and claims analysis including claims of
delay and/or disruptions by the specialty subcontractors." [4]
"Slow
performance by a subcontractor will not excuse the prime's late completion of a
project". [5] Project time management education must provide a
comprehensive address of the coordination of subcontract activities.
Quantity
takeoff and Cost estimating Courses
It
may or may not be feasible to include all specialty contractor work items in the
quantity determination process of the estimating courses. Most courses
ordinarily include the take-off of some items that are typically the
responsibility of a Specialty Subcontractor. The technical courses provide an
excellent opportunity to quantify the work prepared in design assignments that
have typically been intended to demonstrate technical competence.
The
solicitation, receiving, and follow-up of subcontract bids should be a topic of
all cost estimating classes. From the decision to subcontract through the write
up of the scope of work, the student estimator must understand both sides of the
Subcontractor-General Contractor pre-contract phase. The doctrine of
"promissory estoppel" and reasonable reliance to the conflicts
resulting from "bid shopping" should be included in this estimating
education.
It
is, however, most beneficial to have students "price" a (given)
quantity of specialty work to develop a concept of the value of various
components of the project. One method might be to have individual students
responsible for the pricing of different trades resulting in this
"bid" to themselves and other student-general contractors on a
competitive basis against the other student(s) assigned the same trade.
As
a result of the evolution toward subcontracting, the General Contractor's
subcontract bid evaluation and analysis process has an impact on the potential
for project success. An underfunded and/or overloaded subcontractor may not be
able to adequately staff the project with skilled workmen and essential
resources to provide the quality expected nor to meet the time requirements.
Contracts
Courses
While
most construction curriculums contain substantial coverage of the forms and
legal implication of Owner-General Contractor contracts and General Conditions,
the writing of appropriate terms and conditions for General
Contractor-Subcontractor contracts are not addressed in the same depth. The
inclusion of the issues surrounding the subcontracts in courses including legal
and contractual obligation topics is appropriate.
A
contract issued by a General Contractor imposes an legal obligation upon the
contractor to avoid ambiguity and to provide a clear description of the
obligations of the contractor. To often, students perceive that the 16 Divisions
of CSI facilitate the division of work to the specialty contractors. "It is
well established that project owners have no obligation to arrange their
specifications in such a way as to facilitate subcontracting. The prime
contractor has sole responsibility for dividing the work among its subs.
Therefore, there is no substitute for a prime contractor's careful evaluation of
the entire set of plans and specifications prior to allocating work among
subcontractors. If there are any gaps or omissions, it will be the prime's
responsibility to take care of them." [6]
Contract
clauses addressing the, General Contractor's obligation regarding the
relationship of payment to subcontractors to payment by the owner are critical.
"Condition precedent" payment clauses must be understood by both
parties to the General Contractor-Subcontractor agreements.
Changes
and claims are other sensitive issues. The contractor often develops a
"flow down" clause that includes rights and recovery dependent on the
contractor's subsequent claim against the Owner. Recognizing the importance of
the Owner-Contractor relationship, a potential conflict of interest in
supporting the claim can be detrimental to the subcontractor.
From
the subcontractors position, a clear understanding of all contract terms,
wording and potential for negotiations of conditions including hold harmless and
indemnity, flow-down clauses, payment and retention terms, warranties and call
backs, schedule of work, delays and liquidated damages, lien and bond rights,
and of course scope of work including any contingent or pre-conditioned bids.
The American Subcontractors Association's manual "Winning the Battle of
Subcontract Forms" is an excellent reference for educators in need of in
depth information.
Negotiation
and coordination for changes in the project (change management),
schedule/delay/acceleration, and termination are important to both general and
specialty subcontractors. Education exercises that provide application of
decision principles will benefit the student as either future contractors or
subcontractor.
Learning
Needs and Opportunities
All
students entering the building industry will be involved in specialty
subcontractor relationships either as a General Contractor or as a Specialty
Subcontractor. In many circumstances, their initial and possible long range
success will depend upon their ability to handle the situations arising out of
those relationships.
The
number of Speciality Subcontractors far exceeds the number of General Contractor
and Construction Management firms. The graduates of ASC member schools have
typically been employed by the general construction sector while the specialty
contractor group has had to develop managerial staff either through the trades
or from engineering, or non-technical college graduates. One conclusion might be
that the ASC graduate may find a better long-range employment opportunity in a
specialty contracting firm.
CONCLUSION
Project
Management in the building industry is, to a large degree, subcontract
management. A review of text and reference materials provides little, if any,
address of subcontract issues. Given that the success of the project relies on
the performance of subcontractors, then certainly the critical issues in General
Contractor-Subcontractor relationships and potential conflicts merit course
coverage.
There
are two distinct issues in evaluating the education requirement regarding
subcontract management. The first is the management of subcontractors and
subcontracted work by the General Contractor. The second is the managerial
techniques applied and problems incurred by the Subcontractor in the execution
of the contracted work.
The
Authors suggest that coverage of the role and requirements of the Subcontractor
from both the technical and managerial perspectives are essential responses to
both issues. The impact of subcontractor decisions and performance will
influence the success of all graduates entering the construction industry.
Future general and specialty contractors will benefit from a comprehensive
education.
It
is imperative that educators take advantage of the opportunities that are
available in existing courses to provide an adequate understanding of
subcontracting issues from the Specialty Contractor's position. It is easy to
overlook the fact that the pertinent
issues in General Contractor-Subcontractor relations are viewed and approached
differently from each side of the relationship. Expanding coverage of these
perspectives and approaches will better prepare the student to enter the
building industry.
