MODEL SPECIFICATION FOR
HELICAL PILE FOUNDATIONS
COMPRESSION APPLICATIONS
1
SCOPE
1.1 The work consists of designing, furnishing and installing helical piles 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 Pile Designer is the individual or firm generally hired by the Installing Contractor to
design the helical piles.
1.2.3 The Installing Contractor installs and tests (if necessary) the helical piles, 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 helical pile load testing.
1.4 The Owner will be responsible for obtaining any right-of-way or easement access permits
necessary for the helical pile 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 The Owner will be responsible for a horizontal field survey of the helical pile locations prior to
helical pile installation and an elevation survey to determine pile shaft cutoff height subsequent
to helical pile installation.
1.10 The work does not include any post-construction monitoring of pile performance unless
specifically noted otherwise in the contract documents.
