Pile Foundations Scope of Work
Contractors will utilize pressure treated timber foundations for all bridges unless otherwise noted. The following information includes installation method descriptions and
standard associated unit costs:
Typical Piling Installation Method:
Contractors will utilizes a vibratory hammer to drive timber piling for foundations to contracted depth or until refusal.
1. Contracted Depth: Please see “Item A.I - Bridge Description”.
2. Typical Depths:
∙ 10’ or until refusal for Pedestrian/Golf Cart/Light Vehicular
∙ 16’ or until refusal for Vehicular
- Customized Depths: Additional depths might be included in the scope at the request of the client, based on
review of third party provided geotechnical information. Customized depths do not typically alleviate
piling clauses, instead they increase upfront cost in hopes of limiting change orders in the field.
Alternative Piling Installation Notification:
In the event contractor encounters a need for Alternative Piling Installation Methods, the client will be notified with the
discovered field conditions and an approval request to proceed. No additional work will commence without client
approval, therefore, response to requests with immediacy is necessary to avoid downtime.
Alternative Piling Installation Methods:
Alternative Piling Installation Methods utilize various supplemental equipment, materials, and labor, to achieve
appropriate in ground installation of timber piling as verified by EOR. Methods and Materials are dictated by soil
conditions encountered that prevent or prohibit Typical Piling Installation Methods from meeting contracted depth or
refusal requirements. Typical conditions & alternative methods are as follows:
1. Hard or Rocky Substrates: Alternate installation methods may include concrete footers, drilling, foundation
redesign, or a combination of methods, as well as associated materials & labor. Unit Costs are required for:
∙ Auguring/Drilling including all setup/breakdown time:
∙ Concrete footer pricing will be determined by size.
2. Soft or Sandy Substrates: Alternate installation methods may include longer piling, sister piling, splicing, or
a combination of methods, as well as associated materials & labor.
∙ Longer Piling & Sister Piling:
∙ Pedestrian: (from ground) and (from raft/scaffolding) per foot of piling installed
∙ Vehicular: (from ground) and (from raft/scaffolding) per foot of piling installed
∙ Prevailing Wage: (from ground) and (from raft/scaffolding) per foot of piling installed
∙ Splicing:
∙ From Ground:
∙ From Raft/Scaffolding:
∙ Freight: If required, costs are forwarded to client/ client notified ahead of time
Piling Documentation:
All piling installations are tracked via pile logs, that are evaluated by the EOR for Design Conformance. Pile Logs are
signed & sealed by the EOR and included in the close-out documents.
Geotechnical Data:
Geotechnical information, such as soils reports, flow rates,
and other site specific reports, are helpful in obtaining an approximate depth of piling needed for capacity per project.
The client can procure geotechnical services to supply information to prior to the Design and Engineering so that
the information can be incorporated into the design. Soils tests are conducted to a minimum of
50’ to 100’ deep or until refusal, based on stability of the soil. All soil tests/borings are completed as close to the
location of the proposed piling as possible.
Soil Testing and Piling Installation:
Soil testing allows for preparation of expectations for design,
materials, and construction methods to achieve the best-case scenario for an effective scope and anticipating
probable outcomes once construction begins. All piling will be minimally driven to the insertion rate that will supply the
needed capacity (determined through calculations in the engineering phase of the project). The final depth will be
determined in the field during construction of the project.
Engineering Details Scope of Work
Contractor will accommodate standard provisions and
parameters as they pertain to the project including shop drawings and engineering calculations necessary to
verify the structural integrity and loading capacity, such as, the intended live loads and dead loads of structural
components of contractor designs. This contract is limited to the scope of work as described in “Item A”. The following
