The Project Challenge
Every structure location brings a different set of foundation requirements.
New transmission infrastructure can pass through changing ground conditions, access constraints and different construction environments. Foundation requirements therefore need to respond to the conditions at each structure location rather than relying on one standard solution.
The engineering approach must consider the ground, tower reactions, access, services, working space, plant requirements and the practical sequence of construction.
What Needs to Be Understood
Good foundation decisions start with the right project information.
Each of these areas can influence the foundation approach, and they need to be understood together before a solution is developed.
Ground & Site Conditions
Available ground investigation information, geology, groundwater, site variability and working-platform requirements can influence foundation selection and construction planning.
Tower & Structural Requirements
Tower reactions, foundation geometry, interfaces and performance requirements need to be understood together when developing the foundation approach.
Access & Construction Constraints
Access routes, working areas, excavation requirements, services, plant movements and construction sequencing can affect how foundation works are delivered.
Project Interfaces
Survey information, setting out, earthing, stubs, cast-in items, temporary works and other project interfaces need to remain coordinated throughout delivery.
Our Support
Engineering connected with practical site delivery.
Foundation Development
Review project information and develop foundation approaches around ground conditions, tower requirements and constructability.
Setting Out & Site Control
Establish foundation positions, reference information and survey control, with engineering checks completed before construction begins.
Construction Support
Provide engineering and site support during excavation, piling or drilling where required, reinforcement, stubs, cast-in items, earthing interfaces and concrete operations.
Verification & Handover
Coordinate construction checks, engineering hold points, survey information and quality records through to as-built information and project close-out.
From Design to Construction
The foundation solution must be technically sound and practical to construct.
Foundation development needs to consider both engineering performance and how the works will be delivered on site. Ground conditions, access, plant, interfaces and construction methodology can all influence the final approach.
Ground conditions
Available ground information, groundwater and variability between locations inform the foundation approach, engineering assumptions and construction risks that need to be managed.
Tower reactions
Compression, uplift, shear and overturning demands from each tower need to be transferred safely into the ground through an appropriate foundation arrangement.
Access and working space
Access routes, working areas and space for plant and materials can influence which foundation option is practical at each location.
Excavation / drilling requirements
The excavation or drilling method, ground stability and groundwater control need to be considered early so the foundation can be constructed as designed.
Reinforcement, stubs and interfaces
Reinforcement, tower stubs, cast-in items and earthing connections need to be coordinated so that each interface is correctly set before concrete is placed.
Concrete, verification and records
Concrete placement, testing, inspection and survey checks create the quality record needed to verify the completed foundation against the design intent.
Typical Project Journey
From site information to completed foundation.
Site & Project Information
Review ground, survey, access and interface information for each structure location.
Foundation Development
Develop the foundation approach around ground conditions, tower reactions and constructability.
Setting Out & Readiness
Confirm setting out, survey control, access and pre-construction checks before work starts.
Foundation Construction
Carry out excavation, piling or drilling where required, reinforcement, interfaces and concrete operations.
Verification & Quality Records
Record inspections, tests, hold points and survey checks as the works progress.
Handover & As-Built Information
Compile as-built, quality and close-out information for project handover.
Project Outputs
Engineering information carried through the project.
Depending on the agreed scope, AI Engineering can provide information that keeps design intent, site activity and project records connected from early development through to handover.
Outputs are agreed for each project and provided where relevant to the project scope.
