3-5.1 Demolish (Risk). The government is in a generally favorable position to
manage risk relative to cost, time, and environmental hazards. The government is in
somewhat of a less favorable position to manage risk relative to contractor
performance. The government assumes risk and liability for differing conditions
encountered during demolition. The government can reduce the probability of differing
conditions through a thorough survey of the building and an accurate description of
conditions in the contract documents. The government is exposed to time and cost
impacts relative to differing project conditions resulting in contract changes. If a
demolition project is performed in accordance with prevailing safety and environmental
standards, there is typically no risk to the public.
3-5.2 Recycle (Risk). A recycling program may delay subsequent activities such as
the ability to use the site. Unless sufficient liquidated damage provisions are included in
the contract, the government assumes indirect effects of deficient contract performance.
There is typically no risk to the public if a demolition project is performed in accordance
with prevailing safety and environmental standards. There is possible exposure to the
hazards of asbestos and/or lead if contaminated materials are released to the public
through recycling or reuse. The government should require a contractor to monitor and
control release of contaminated materials into recycled material feedstock.
3-5.3 Recover (Risk). The government assumes the risk and liability for differing
conditions encountered during recovery and removal. The contractor assumes the risk
of recovery expenses and the value of recovered materials. Transferring this risk holds
the government harmless, but at a reduced income due to contingencies. There is
possible exposure to the hazards of asbestos and/or lead if contaminated materials are
released to the public through recovery and reuse.
3-5.4 Deconstruct (Risk). Personal injury liability is an issue when deconstructing a
building since manual labor is used to perform most of the work. The probability of
jobsite hazards can be reduced through the administration of a safety management
program and adherence to safety and health regulations. With deconstruction, there is a
risk of encountering unforeseen conditions. The government can transfer the risk of
differing conditions, but at a significant price due to inflated contractor contingencies.
IMPLEMENTATION. Solicitations for traditional demolition contracts are
generally in the form of a Request for Proposal (RFP). The lowest qualified bidder is
generally selected as the contractor. A typical demolition RFP requires contractors to
submit such information as qualifications and description of the proposing organization,
a list of sub-contractors, a project schedule, and a list of completed projects and
references. Since the method of demolition is irrelevant, no plan or proposal beyond a
schedule is usually required. Where UFGS 01572 Construction and Demolition Waste
Management is included in the contract documents, a waste plan is required that
encourages reuse and recycling, and explicit requirements can be added.
To achieve higher rates of recovery, building material reuse and recovery must be part
of the project planning and contracting process. A typical demolition contract, however,
