A properly designed inspection checklist form can demonstrate
due diligence in complying with regulations, manufacturer’s instructions, and
workmanship standards. You can use it to set expectations for what needs to go right, and
once completed it can serve as a record of what actually happened.
The trade contractor’s crew supervisor should use an
inspection checklist to perform inspections on every job. If the trade has several phases
of work on a home, prepare a separate inspection form for each one. In addition, the
builder can use a copy of the same forms while performing quality reviews.
ISO 9000, the internationally recognized quality control
standard, sets requirements necessary to assure conformance to specifications. The ISO
9000 approach not only assures that specifications are met but also confirms that all the
elements of a reliable construction process are in place.
Jobsite Installation Record provides basic information
about job location, start date, and the type of product or system that is to be installed.
Job Readiness questions verify there are no adverse
conditions that impact quality and the job is suitable for work to begin. This should
include availability of installation instructions and adequacy of work performed by
previous trades, as well as building or environmental conditions that can affect quality.
Use of Materials should be documented. When materials
affect quality, the inspection form should capture specific information on primary as well
as secondary materials when they make a difference to the completed job.
Installation Inspection questions verify that product
manufacturer’s specifications are followed and that workmanship meets expectations.
Examine manufacturer’s installation instructions, NER product evaluation reports,
codes, and regulations to identify key requirements that need to be followed for
performance and durability. Supplement this with provisions for the needs of the following
trades and your own expectations. Whenever inspection questions verify conformance to
dimensional specifications, actual measurements should be recorded. Also verify the use of
specific equipment or tools if they affect quality results.
Problems Found should be recorded, even if they are
corrected. When the problem results in a deviation from specifications, note the
deviation.
Job Complete sign-off should be done by the
responsible craftsman after verifying satisfaction with workmanship and that the work is
complete to specification. List any remaining repair items to be completed.
I encourage you to collaborate with your trade contractors
and product manufacturers to prepare inspection checklists for each of your trades. The
jobsite inspection checklist is an important element of a builder’s quality control
system to help you build problem-free, durable homes.
