and Legal Perspective

ABSTRACT
Based on recent experience in construction litigation, it appeal’s that much confusion
exists regarding written instructions used by contractors during the course of a project.
A variety of written instructions are typically available, including: the applicable build¬
ing code, industry standards, and manufacturer’s instructions. On larger projects, plans
and specifications may be prepared by an architect, engineer, or roof consultant. If the
completed project becomes the subject of litigation, the written instructions are care¬
fully reviewed and compared with the as-built conditions to determine compliance.
This process is a primary element of nearly all construction litigation cases.
The first part of this paper will: 1) present the methods used during a forensic engi¬
neering investigation to determine if the completed work is consistent with written
instructions, 2) describe the use and interpretation of building codes, industry stan¬
dards, and manufacturers’ instructions and how to resolve discrepancies that may exist
between them; and 3) provide numerous examples of lessons learned from construc¬
tion litigation cases.
The second part of this paper will: 1) discuss the role of the forensic consultant in con¬
struction litigation, 2) provide insight regarding the legal interpretation of various
forms of written instructions and describe their legal hierarchy, 3) describe examples
of interpretations made in construction litigation cases; and 4) offer suggestions on
standards of care to reduce exposure to liability.

Background
It has been reported that the
first set of instructions provided
to a contractor were those of
God’s instructions to Noah
regarding the construction of the
ark. If Noah had failed to comply
with God’s instructions (and
Noah resided in the United
States), he would likely be named
in a deficient construction law¬
suit. Enter the forensic engineer –
to determine who was responsible
for the non-compliance and the
extent of associated damages.
The scenario described above
would have been easier to sort
out than projects constructed in
the 21st century. Today’s projects
are subject to instructions provid¬
ed by more than one source.
These instructions include, but
may not always be limited to, the
following:
• The building code;
• Manufacturers’ instruc¬
tions; and
• Industry standards.
Figure 1
Larger projects may also include plans and/or speci¬
fications prepared by a design professional such as an
architect, engineer or roof consultant. Additionally, con¬
tract documents may define the scope of work to be car¬
ried out by the general contractor or subcontractors. The
flowchart below describes the general hierarchy of the
instructions available to a modem contractor.
Hodgin and McCutchen—73
Obviously, the construction world is not this straight
forward. Discrepancies exist. A general discussion of
each set of instructions is provided below.
THE INSTRUCTIONS
Building Code
The construction industry has been making attempts
to consolidate the numerous building codes used in the
United States into one code [International Building Code
(IBC)]. This task is far from complete and could be the
topic for an entirely different paper. This paper, however,
focuses on construction litigation. Projects currently in
litigation were typically completed prior to the adoption
of the IBC and are most often (but not always) subject to
one of the following building codes:
• Standard Building Code (SBCCI)
• National Building Code (BOCA)
• Uniform Building Code (ICBO)
• One and Two Family Dwelling Code (CABO)
The map shown below was adapted from the RCI
Building Codes & Standards Reference Guide. The map
shown is not current; however, it serves to illustrate the
geographic distribution of building code influence from
an earlier date. Note that some states had not adopted a
model building code at the time the map was assembled.
The building code (regardless of which one may
apply) provides the bare mini¬
mum requirements that a con¬
tractor must meet. In many
cases, stricter requirements
may apply. The building code
represents a base set of
instructions. The building
code references numerous
consensus standards that are
incorporated into the building
code just as if they were
physically contained therein.
Examples of typical standards
referenced by building codes
include:
1) Other building codes
(i.e. gas, mechanical,
and plumbing codes,
and the National
Electrical Code), col¬
lectively referred to as
the “technical codes”;
2) Material and/or installation standards [i.e.,
American Society for Testing and Materials
(ASTM), American National Standards Institute
(ANSI)]; and
3) Industry references [i.e. American Society of
Civil Engineers (ASCE), Engineered Wood
Association (APA), Cedar Shake and Shingle
Bureau (CSSB), and Truss Plate Institute (TPI)].
A complete list of all reference standards is included
in each building code. A contractor should be familiar
with all of the standards that apply to his work.
Manufacturers’ Instructions
When published instructions are available from a
manufacturer, they should always be consulted. The con¬
tractor should clearly understand the instructions provid¬
ed by the manufacturer. More importantly, the project
supervisor and laborers employed by the contractor
should have the same understanding of the instructions
and be prepared to follow them during the course of the
construction project.
If a design professional is involved with a project, it
is important to determine if any discrepancies exist
between the manufacturer’s instructions and the plans
and/or specifications prepared by the design professional.
In most cases, the plans and specifications will supersede
Hodgin and McCutchen—74
the manufacturer’s instructions. This is particularly true
when a manufacturer provides generic details and more
specific detail is required from a design professional.
Industry Standards
All contractors should be familiar with standards
within their respective industry. Industry standards serve
as a generic “baseline” for workmanship when more spe¬
cific manufacturer instructions are not available. That is
not to say that industry standards should only be refer¬
enced in those circumstances. Rather, a contractor should
always follow industry standards unless more specific
instructions are available.
What constitutes an industry standard? In simple
terms, an industry standard should: 1) represent the
industry as a whole and 2) provide accepted and objec¬
tive information regarding workmanship. Is the NRCA
Roofing and Waterproofing Manual an industry standard?
Some experts argue that it is not. The argument is based
on the idea that the information is being provided by a
contractor-driven organization and does not represent the
roofing industry as a whole (the first requirement). While
I have not had the opportunity to memorize all of the
information in this (now four-volume) manual, I am not
aware of any information that is not generally accepted
and objective (the second requirement). In my experi¬
ence, arguments such as these are typically made by
experts with special interests. For example, someone rep¬
resenting a manufacturer could argue that the NRCA
Manual does not represent an industry standard (if it is
inconsistent with the manufacturer’s instructions). If one
represents a contractor, this is a much more difficult
argument.
Plans and/or Specifications
A design professional is often required on larger pro¬
jects. For purposes of this paper, the design professional
would likely be an engineer, architect, or roof consultant.
The design professional may be required to produce a set
of plans and/or specifications. These instructions should
be consistent with all other instructions provided to the
contractor, but should provide more detail where neces¬
sary. For this reason, the instructions provided by the
design professional typically supersede all other instruc¬
tions.
If discrepancies exist between the instructions pro¬
vided to the contractor, they should be brought to the
attention of the design professional for clarification. All
clarifications or changes should be clearly documented in
writing. A one-page letter clarifying an issue can be valu¬
able evidence in a construction litigation case.
Contract Documents
In addition to the instructions described above, con¬
tract documents may also provide instructions to a con¬
tractor. Typically, these contracts (such as standard AIA
agreements) include a list of project documents (instruc¬
tions) to be followed by the contractoiyContract docu¬
ments also typically define the scope of the work, the
project schedule, and the payment schedule.
FORENSICS 101
The forensic engineer (or some other expert retained
by an attorney to validate the claims of a property owner,
contractor, subcontractor, manufacturer, etc.) must deter¬
mine which set of instructions apply to the subject con¬
struction project. The date of the construction permit is
typically used to determine the applicable building code.
In the absence of the building permit, the dates of the
project drawings (if available), the date of construction,
and the Certificate of Occupancy (C.O.) date(s) are use¬
ful in determining the applicable building code. A quick
call to the overseeing municipality should be made to
verify the applicable building code and to obtain a copy
of the adopting ordinance.
During the course of a comprehensive survey of the
subject property, dates of manufacture should be docu¬
mented (i.e., roofing products, APA-rated panels, win¬
dows, doors, etc.). These dates can help determine what
(if any) instructions were available to the contractor
regarding the installation or application of a particular
building product. It is important to determine that these
instructions [manufacturer and/or industry standard(s)] were available to the contractor at or before the date of
construction.
Any other instructions, such as project plans, specifi¬
cations, and contracts, should be reviewed for adequacy,
completeness, and detail. The plans and specifications
should be compared with as-built details (visual observa¬
tions) to determine the extent of inconsistency (or com¬
pliance).
If the project instructions are not followed, the foren¬
sic engineer must determine the consequence of the noncompliance,
the actions necessary to correct the situation,
and the cost to perform the repairs. Unless a forensic
expert has specific experience regarding construction
costs, this opinion is better provided by a qualified local
contractor. The results of this information can be summa-

rized in a table similar to the sample shown in Figure 3.
This table provides a useful format to summarize the
issues of a particular construction project. A summary
such as this can also serve as a guide when answering
questions in a deposition, particularly when accompanied
by all of the referenced documents. Once the forensic
experts have identified the issues, it is up to the construc¬
tion litigation attorneys to present and argue the position
of his/her client.
PART II – LEGAL
Background
While the first set of instructions provided to a con¬
tractor may have been God’s instructions to Noah regard¬
ing the construction of the ark, the instructions were
probably two-fold:
1. Noah, build the ark (or how long can you tread
water?).
2. Build the ark correctly, and in conformity with the
appropriate building codes and industry standards
so that it doesn’t sink and everyone drowns!
The failure to follow the first set of instructions
would have simply resulted in no one left living and,
therefore, no plaintiffs. Once Noah, the contractor, under¬
took the construction of the ark, the duties therein arose
to follow the appropriate implicit and explicit instruc¬
tions dealing with the International Ark Building Code,
the manufacturer’s instructions dealing with the appropri¬
ate boat construction and industry standards for ark con¬
struction (it must float for 40 days!)
Instructions
The contractor needs to both follow the instructions
provided by the manufacturers and experts acquainted
with the project, and must give appropriate instructions
to ensure compliance with industry standards and build¬
ing codes for both his employees and for his subcontrac¬
tors.
We have presented a flow of information, action, and
reaction that will be a construction defect lawsuit. For
simplicity’s sake, we have designated the party that
would be the plaintiff as Acme Homeowners’
Association (“Association”). Acme HOA was incorporat¬
ed to administer the affairs of Acme Horizontal Property
Regime (Acme Condominium).
Do Construction Problems Exist?
In a typical condominium development in the State
of South Carolina, the control of the board of directors
passes from the developer’s appointed representatives to
the independently elected board of directors at some
point through the developmental scheme. As soon as this
homeowner-elected board of directors takes power, it is
our contention that it has some due diligence to investi¬
gate financial and physical plant matters related to the
property of the regime. The regime could easily have
been in existence for many years while a phased develop¬
ment scheme was put in place for the project with the
developer in charge of the board of directors. As such,
there has been no independent authority to review the
financial and physical plant issues for an extended period
of time.
Hodgin and McCutchen—76
The Association should undertake some initial prop¬
erty inspection and inspect closely the records and
reports of required maintenance and repairs for the
Association. In the coastal region of South Carolina,
there are constant problems with water penetration into
structures. If the board has reason to believe that it may
have construction-related deficiencies and problems, it
should hire a third party expert to undertake destructive
testing to try to determine the existence, scope, and
nature of the construction deficiencies and associated and
resulting damage that may exist at the property. There are
a number of ways in which the board of directors and
independently employed management can initially dis¬
cern the possible need for repair and reconstruction
investigation issues.
In any event, once the board of directors and the
Association have notice of issues that warrant further
investigation, it is imperative that action be taken. Most
states have both Statutes of Limitation and Statutes of
Repose dealing with time frame limitations in which
actions can be brought for construction defects and defi¬
ciencies. The first step is to hire a competent, indepen¬
dent professional to undertake destructive testing to
determine the existence and scope of construction defi¬
ciencies at the project.
What Are the Nature and Extent of the Problems?
The expert is retained and coordinates destructive
investigative testing for the property under the control of
the Association. Such investigation should be widespread
and the expert should be authorized to undertake all nec¬
essary investigation to establish the existence or nonexis¬
tence of deficient construction and the resulting conse¬
quences at the project. It is imperative that a qualified
expert be retained who can thoroughly support the results
and findings ascertained and be prepared to testify in
deposition and trial at a later date. It is most helpful
when the retained expert provides detailed observations
and narratives and substantiates all opinions and observa¬
tions by thorough photographic support. Each opinion or
observation should be supported by photographic evi¬
dence and the expert should provide substantiation for
the violation of building codes, industry standards, and
the like.
The results of the investigation by the expert and his
report are the blueprint and instructions by which the
Association takes action against the parties responsible
for the defects and deficiencies.
Now what?
The expert delivers his narrative report and profes¬
sional opinion with photographic backup. What should
the board do? The board of directors is imputed with the
responsibility to administer the affairs of the Association
for the best interests of the owners. All boards have all
such statutory and case law standards as may exist in a
particular state which apply to eleemosynary (non-profit)
corporations. Further, the board is imputed with certain
fiduciary standards which would be widely applicable to
most such eleemosynary corporations.
The Association hires an attorney to evaluate the
Association’s position. If warranted, the attorney brings
an action against the principal parties involved with the
development, construction, and oversight of the regime
property. Here, we focus upon the contractor and its role
in the process.
The contractor is hired by the developer to construct
the project. A written contract will contain the specifics
on the contractor’s duties and responsibilities. Contracts
will control the relationships by, between, and among the
developer, the contractor, and the design professional.
However, for the purposes of this discussion, our focus is
on the contractor.
Many of the general theories of negligence and
breaches of implied warranties that could be applicable
to the contractor arise out of the alleged failure to follow
instructions, be that explicit instructions by the manufac¬
turer and/or explicit or implicit instructions that relate to
building codes and industry standards. Some general
allegations are as follows:
1. In failing to provide for the proper construction of
the project.
2. By deviating from the plans and specifications as
designed.
3. In failing to employ practices and methods of con¬
struction and construction oversight conforming to
normal, customary, and ordinary standards of the
construction industry.
4. By allowing the installation of, or installing mate¬
rials and products not in accordance with the pro¬
jects plans and specifications.
5. In failing to provide for proper supervision and
oversight of employees, agents, and subcontractors
and/or trades in order to ensure that all work pro¬
ceeded and was completed in accordance with the
project plans and specifications and also in confor-
Hodgin and McCutchen—77
mity with customary and ordinary industry stan¬
dards, code requirements, and good construction
practices.
The complaint initiates that action by the Association
to address the construction deficiencies and defects aris¬
ing out of – among other items – the contractor’s failure
to follow instructions or standards.
Development of the Case
As the lawsuit progresses, additional investigative
work and destructive testing will be undertaken by the
retained expert to further substantiate and corroborate the
positions taken by the expert at the initiation of the
process. The other parties in the action will retain experts
who will review all presented materials of the
Association’s expert and find alternatives for repair with¬
in the scope of industry standards and building codes.
This process includes the ongoing exchange of written
materials between counsel for the various parties, as well
as depositions for specific review of not only the position
of the expert for the Association, but also the positions of
the experts for all other parties in the action, including
the contractor.
The instructions and standards for the contractor will
be intensely debated by the various parties in that there
are not always hard and fast rules, but there are also
somewhat flexible instructions and standards. This por¬
tion of a lawsuit takes many months and elicits every
prospective position possible from the various experts
retained by the parties as to the proper methods used in
the construction of the project. Once all discovery has
been completed, the case now moves towards a resolu¬
tion.
How Does It End?
A construction defect case will generally end by res¬
olution through mediation, arbitration, or a trial of the
case. It will only reach this point for a prospective favor¬
able resolution with solid facts and strong experts.
Mediation involves all parties sitting down with the aid
of a mediator who attempts to bring parties to a point of
resolution with compromises by all those who have
involvement in the case. In that there is no perfect posi¬
tion, the parties must be willing to compromise and
understand the strengths and weaknesses of all positions
presented. By so doing, the mediator can draw parties
toward some point of resolution where no one is fully
happy and no one is fully mad. Mediation is just that: it
is the art of compromise to reach a resolution based on a
complete understanding of the strengths and weaknesses
of the case.
Arbitration is the second alternative for case resolu¬
tion. An arbitrator hears a case much as a judge would
and renders a decision based on the presentation of evi¬
dence and material. The conduct of an arbitration is
much like the trial of the case, with looser evidentiary
rulings and no jury. Generally, an arbitrator’s award is
final in the case from which no appeal can be had.
If other methods are unsuccessful, the case may go to
a trial, which in the State of South Carolina would be in
the Circuit Court. At the conclusion of the case, the deci¬
sion as to its outcome would, of course, be in the hands
of a jury.
Lessons to be Learned
Follow the instructions, including industry standards
and building codes, and the workmanship should not be
subject to an action for construction deficiencies (or it
should at least be easily defended). Do not follow the
instructions, and more often than not, the parties aggriev¬
ed by the failure to follow those will bring action and
seek financial recovery to cure the defects.
The choice is clear. The contractor should closely
review the job and submit contract proposals that ade¬
quately allow for adherence to instructions and standards.
If the contract is underbid, the contractor inevitably must
try to cut comers. Instructions are not followed and stan¬
dards not adhered to and problems and deficiencies are
discerned. The result: a lawsuit is filed. Do it right (fol¬
low the instructions) the first time!
