Chapter 3

Hydraulically-Driven Push Piers

MODEL SPECIFICATION FOR

PUSH PIER FOUNDATIONS

COMPRESSION APPLICATIONS

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.
