MODEL SPECIFICATION – HYDRAULICALLY-DRIVEN PUSH PIER SYSTEMS
Chapter 3
Hydraulically-Driven Push Piers
MODEL SPECIFICATION FOR
PUSH PIER FOUNDATIONS
COMPRESSION APPLICATIONS
1
SCOPE
1.1 The work consists of designing, furnishing and installing push piers and load transfer devices
used to support compressive loads according to the project Plans and these specifications.
1.2 The parties and contract terms referred to in this specification are as follows:
1.2.1 The Owner is the person or entity that owns the facility or will own the facility once it
is completed. The Owner may have contractual agreements with, and be represented
by, other parties such as engineers, architects, or contractors that perform services
under the direction of the Owner. Where Owner is used in this specification, it refers
to the Owner or the Owner’s contracted representatives separate from the Installing
Contractor.
1.2.2 The Pier Designer is the individual or firm generally hired by the Installing Contractor to
design the push piers.
1.2.3 The Installing Contractor installs and tests (if necessary) the push piers, and possibly
performs other tasks associated with the project.
1.2.4 The Plans refer to the contract documents; including but not limited to the drawings and
specifications for the project.
1.3 The work may include push pier load testing.
1.4 The Owner will be responsible for obtaining any right-of-way or easement access permits
necessary for the push pier installation.
1.5 Unless otherwise noted, the Installing Contractor shall provide all labor, tools, equipment and
materials necessary to accomplish the work.
1.6 The Owner will provide suitable access to the construction site for the Installing Contractor’s
personnel and equipment.
1.7 Unless specifically noted otherwise in the contract documents, the Owner will remove and
replace any structures, utilities, pavements, landscaping, or other surficial improvements in the
work area as necessary to facilitate the work.
1.8 The Owner will be responsible for overall construction oversight to preclude the development of
unsafe conditions.
1.9 Unless specifically noted otherwise in the contract documents, the Owner will be responsible for
a horizontal field survey of the push pier locations prior to push pier installation and an elevation
survey to determine final structural lift subsequent to push pier installation (if necessary).
1.10 The work does not include any post-construction monitoring of pier performance unless
specifically noted otherwise in the contract documents.
