SCOPE
1.1 The work consists of designing, furnishing and installing helical anchors and load transfer
devices used to support tension 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 Anchor Designer is the individual or firm generally hired by the Installing Contractor
to design the helical anchors.
1.2.3 The Installing Contractor installs and tests (if necessary) the helical anchors, 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 anchor load testing.
1.4 The Owner will be responsible for obtaining any right-of-way or easement access permits
necessary for the helical anchor 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 anchor locations prior to
helical anchor installation and a post installation survey to determine anchor shaft cutoff lengths
(if necessary).
1.10 The work does not include any post-construction monitoring of anchor performance unless
specifically noted otherwise in the contract documents.
