Understanding Structure Construction
The structure is only one part of the construction sequence.
Successful tower and pole installation depends on more than lifting the structure into position. Access, setting out, working areas, assembly, lifting methodology, temporary arrangements, outage interfaces and associated components all need to align with the approved project information.
How Tower & Pole Construction Works
From site preparation to an erected and checked structure.
Prepare the Site
Review access, structure location, working area, plant, materials, lifting requirements and approved construction information.
Assemble the Structure
Tower sections or pole structures are assembled with the required steelwork, crossarms, stays and associated components.
Controlled Erection
The structure is erected in accordance with the approved methodology, lifting arrangements and project sequence.
Complete & Verify
Final steelwork, earthing, stays, interfaces and construction checks are completed as required by the project.
Structure Types
Different structures require different construction sequences.
Steel Lattice Towers
Assembly and staged erection of overhead-line tower structures, including works planned around the applicable project and outage requirements.
Wood Pole Structures
Setting out, preparation, erection and completion of wood-pole structures with their associated steelwork and construction components.
H-Pole & Terminal Structures
Multi-pole structures incorporating steelwork, crossarms, stays, earthing and associated terminal interfaces where included within the project scope.
Construction Considerations
The details around the lift matter as much as the lift itself.
Access & Working Area
Access routes, structure locations, working areas and plant requirements are considered before erection activities begin.
Setting Out
Structure and associated reference positions are established from the approved project information where required.
Assembly & Steelwork
Tower or pole components, crossarms, stays and associated steelwork are assembled in the required construction sequence.
Lifting & Erection
Lifting operations and structure erection are carried out to the approved methodology and project controls.
Outage & Network Interfaces
Activities are coordinated around the network conditions, permits and outage requirements applicable to the works.
Quality & Completion Checks
Construction checks, hold points and relevant records support completion and handover.
Simple Process Flow
How does a structure move from project information to completed construction?
- Approved Project Information
- Site & Access Preparation
- Structure Assembly
- Controlled Erection
- Associated Steelwork / Earthing / Interfaces
- Checks & Handover
What AI Engineering Does
Practical structure construction support from preparation through erection.
AI Engineering works with the approved project information and construction methodology to coordinate the site requirements, structure assembly, erection activities and associated completion works required within the agreed scope.
- Site and construction preparation
- Structure and steelwork assembly
- Controlled erection activities
- Associated stays and structural components
- Earthing and interfaces where included
- Construction checks and records
Where It Fits in Construction
Connecting the foundation or pole location with the line works that follow.
Tower and pole construction forms the physical link between the prepared foundation or pole location and the later conductor, OPGW and interface activities. The structure needs to be assembled, erected and completed in the correct sequence so that subsequent line works can proceed from a controlled and verified starting point.
Project Outputs
Records that support construction and handover.
Exact records and outputs depend on the agreed scope, client requirements and structure type.
Construction RAMS
Task-specific method statements and risk-control information applicable to the agreed works.
Setting Out / Site Records
Relevant location, preparation and site engineering records where required.
Lifting & Erection Records
Project-specific erection or lifting records where these form part of the agreed documentation.
Structure & Steelwork Checks
Construction checks associated with assembled and erected structural components.
Earthing / Interface Records
Relevant earthing or interface information where included within the project scope.
Completion & Handover Information
Project-specific completion and construction records prepared for handover.
