LEAK INVESTIGATION AND DETECTION 13.17
The remedial action plan should outline the repairs necessary, listing all systems and
materials necessary. Often the assistance gathered from the manufacturers, distributors,
and representatives in the investigation stage is used to create a guide specification for the
remedial repairs. The remedial plan should be very specific, outlining the actual envelope
renovations and the required materials and systems necessary in these renovations.
The plan might include only written descriptions in the form of guide specifications that
can be completed with “in-house staff” or used as a basis for receiving bids and proposals
from waterproofing and roofing contractors. Scaled drawings might be necessary if the
action plan is complicated, to ensure that the work is completed properly.
The firms offering assistance in the investigation stage are likely to offer to prepare
these documents for their clients, especially if their products are included in the remedial
action plan. Should a contractor not involved in the investigation stage desire to substitute
methods, systems, or products, these should be carefully reviewed to ensure they meet the
intent of the original action plan and can successfully provide the protection required.
Chapter 8, Remedial Waterproofing, can be used as a resource in planning a remedial
action plan. Chapter 16 provides a list of manufacturers that also can provide assistance in
both the investigation and remedial planning stages. Chapter 15 provides a series of guide
specifications that can be consolidated into the specifications for materials or systems used
in the repair procedures.

CORRECTIVE MEASURES IMPLEMENTATION

Once a remedial action plan has been completed, it should be implemented as soon as pos-
sible to prevent further damage to the envelope. Building owners should carefully review
the proposal received, to correct the situation if outside assistance is required. Consultants
and material distributors can be helpful in preparing the bid and proposal documents for a
remedial action plan.
Selecting incompetent or inexperienced contractors might prevent the work from
being completed properly or even create additional problems through damage to sur-
rounding portions of the envelope. Chapter 12 provides a standard qualification format
that can assist in selecting qualified contractors to complete the repairs. This form
should be requested from every potential source for completing the required fieldwork.
Once potential bidders have been “short-listed” by reviewing the qualifications of
potential offerers, a bid package must be prepared to ensure that all contractors are bidding
on the identical scope of work. Otherwise, the building owner might find themselves com-
paring “apples to oranges,” and not being able to accurately compare the proposals and
prices. A general outline of a proposal package should include
● A general description of the scope of work that includes the results the owner expects
after the work is completed.
● Insurance and bonding requirements for the contractors.
● Outline of who will supervise the contractor’s work, such as in-house staff or outside
consultants, including their rights to inspect and reject work and approve payment
applications.
