Ground Screws for Decking & Boardwalks
Purpose of this page. Decks and boardwalks need foundation decisions that account for pedestrian loading, lateral stability, wet or waterfront exposure, timber or steel interfaces and sensitive ground. It explains the engineering and procurement route without treating a catalog example as an approved project model.
Application decision context
Water levels, scour, soft layers, frost, seasonal movement, public access and handrail loads can control the foundation. Reducing excavation may benefit a sensitive site, but installation access, disturbance, durability and permitting still need a project assessment.
Required project inputs
- Deck or boardwalk layout, reactions and lateral-load path
- Soil profile, water level, scour, frost and settlement conditions
- Timber or steel beam connection and adjustment requirements
- Corrosion exposure, material compatibility and inspection access
- Environmental permit, equipment access and construction sequence
Configuration and interface route
Pile length, helix and head detail follow the ground and structural reactions. Beam saddles, caps or brackets need drainage, bolt access and compatible materials. Bracing or frame action may be required where slender supports carry lateral or handrail loads.
Manufacturing and verification plan
Proof or production tests, installation records and level surveys follow the project plan. Coating, material and head fabrication records support durability control. Inspection access and replaceable details are planned where water, debris or vegetation can hide corrosion or movement.
Installation, logistics and site coordination
Light equipment and modular construction can reduce disturbance where access allows, but load limits, platforms and environmental controls must be defined. Components are sequenced to maintain stability. Removal and ground restoration are planned if reversibility is a project goal.
Design and supply boundaries
- Waterfront use requires scour and durability review
- Coating thickness alone does not define service life
- Handrail and crowd loads need a lateral-load path
- Environmental permission and access may control feasibility
Documents to define before release
- Layout, reactions and lateral-stability basis
- Ground, water, scour and frost information
- Pile and beam-interface drawings
- Installation, test and survey records
- Material and corrosion-protection records
- Inspection, maintenance and removal plan
The Product Data Center shows how this application connects to the product family and configuration route. Public catalogs support orientation only. The approved calculation, drawing, bill of material, quotation, ITP and contract define the supplied scope. Use the Evidence Center to request the records applicable to the actual order.
Ground Screw Pile Technical Data Template
Use this template to define a project-specific pile schedule. Dimensions shown in a catalog are indicative until the reactions, ground, durability and connection requirements have been reviewed.
Required design inputs
- Compression, uplift, shear and moment reactions
- Geotechnical profile, groundwater, frost and obstructions
- Pile-head interface, tolerances and supported-system geometry
- Design life, soil/atmospheric corrosivity and inspection access
- Installation equipment, test locations and acceptance plan
Decision boundaries
- Not selected from soil description alone
- Installation torque is a control only where a project-specific relationship is approved
- Capacity requires design and the agreed verification method
- Coating and sacrificial thickness follow the exposure and design-life assessment
