Bascule Bridge and Moveable Bridge Construction Risk Assessment — Generated Instantly for £29
Describe the moveable bridge project — waterway crossing, foundation method, counterweight and drive system. We generate a fully written, UK-compliant risk assessment covering working over water, excavation, lifting operations and mechanical hazards in minutes.
Used by civil engineering contractors, structural steel erectors and waterway construction specialists across the UK
🌉 Building a bascule bridge over a canal with foundation excavation? Mention the waterway, excavation depth, counterweight type and lifting method — we'll include working over water, temporary works and LOLER-compliant lifting controls specific to your project.
Legal requirements for bascule and moveable bridge construction
The Construction (Design and Management) Regulations 2015 apply to bascule bridge construction as a notifiable civil engineering project, requiring a principal designer and principal contractor to coordinate health and safety across excavation, structural steel, and mechanical installation phases. Regulation 4 requires clients to ensure suitable arrangements are made for managing the project safely from design through to completion.
Working over or adjacent to a canal introduces drowning risk, which must be controlled under the general duties of the Health and Safety at Work etc. Act 1974. A written risk assessment must demonstrate how you will prevent falls into water, provide rescue equipment, and liaise with the navigation authority to manage boat traffic during construction — this is expected by principal contractors, the client and HSE inspectors alike.
Foundation excavation near a watercourse must comply with the excavation provisions under CDM 2015 and account for groundwater ingress, bank stability and temporary works design. Lifting the bridge deck, steelwork and counterweight is subject to the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), which requires a documented lift plan, competent supervision and thorough examination of lifting equipment.
Confirming that anyone entering the site holds a valid understanding of these duties, along with a suitable and sufficient risk assessment, is a legal requirement under the Management of Health and Safety at Work Regulations 1999 before work commences.
How it works
1. Describe the project
Tell us the bridge type, waterway crossed, foundation method, excavation depth, counterweight arrangement and lifting equipment involved. Mention if the canal remains navigable and whether workers will access confined spaces below deck.
2. Let the app take the strain
Anyrisks produces a fully written, UK-compliant risk assessment referencing CDM 2015, LOLER 1998 and the Work at Height Regulations 2005 as relevant to your bridge project.
3. Instant download and use
Download as PDF and Word. Include it in your project's construction phase plan, share it with the principal designer, or file it for site compliance. £29, no subscription.
What it covers
Every bascule bridge risk assessment is written in full — covering all civil, structural and mechanical hazards specific to your project.
Working over and adjacent to open water — drowning prevention
Foundation excavation collapse and temporary works support
Groundwater ingress and dewatering during excavation
Piling and caisson operations near the watercourse
Counterweight installation — crushing and entrapment hazards
Hydraulic and electro-mechanical drive system hazards
Lifting operations under LOLER 1998 — deck and steelwork
Confined space entry — counterweight pits and below-deck chambers
Working at height on towers, decks and abutments
Navigation authority liaison and boat traffic management
Structural steel erection and temporary bracing
Manual handling of bearings, hydraulic units and fixings
Plant and vehicle movement on a constrained waterside site
Emergency and rescue planning for man overboard scenarios
Works for
From new-build bascule bridges to refurbishment of historic moveable structures, Anyrisks covers every stage of the works.
What customers say
"We're building a bascule bridge over a canal in Wales and the risk assessment covered the foundation excavation right through to the counterweight lift. Nothing generic about it."
Rhys Owen
Civil engineering site manager, Newport
"Working over live navigation is a headache to document properly. This picked up on drowning prevention and the navigation authority liaison without me having to spell it out."
David Fenwick
Structural steel contractor, Yorkshire
"The lift plan section referencing LOLER for the deck and counterweight was exactly what our principal contractor asked for. Saved us hours drafting from scratch."
Anita Sharma
Bridge engineer, Bristol

Frequently asked questions
What is a bascule bridge and why does it need a specialist risk assessment?
A bascule bridge is a moveable bridge that pivots on a horizontal axis using a counterweight to raise the deck, commonly built over canals and navigable waterways. Construction involves working over water, heavy counterweight mechanisms, deep foundation excavation and hydraulic or electro-mechanical drive systems, which together create hazards not covered by a general construction risk assessment.
Does this cover working over a canal or navigable waterway?
Yes — describe the waterway, whether it remains navigable during works, and whether scaffolding, pontoons or temporary works platforms will be used over water. The assessment will include drowning prevention, rescue planning and Canal & River Trust or navigation authority liaison requirements.
What regulations apply to bascule bridge construction?
The Construction (Design and Management) Regulations 2015 apply to the whole project, requiring a principal designer and principal contractor where there is more than one contractor. The Work at Height Regulations 2005 apply to deck and tower work, and the Confined Spaces Regulations 1997 apply where workers enter counterweight pits, culverts or below-deck chambers.
Does it cover the foundation and excavation works?
Yes — mention the foundation type (piled, pad, caisson) and excavation depth near the waterway. The assessment will address excavation collapse, groundwater ingress, temporary works support and proximity to the watercourse under the Construction (Design and Management) Regulations 2015.
Can it cover the counterweight and mechanical/hydraulic systems?
Yes — describe the counterweight arrangement (cast iron, concrete or steel) and whether the drive is hydraulic, electric or manual. The assessment will cover crushing hazards during installation, testing of the lifting mechanism, and compliance with the Provision and Use of Work Equipment Regulations 1998 (PUWER).
Is this suitable for a project in Wales specifically?
Yes — Anyrisks assessments apply UK-wide legislation, which is the same across England and Wales for construction health and safety. Mention the specific location and waterway and any Welsh-language or Natural Resources Wales requirements will be reflected in the assessment where relevant.
Does it include lifting operations for the bridge deck and counterweight?
Yes — mention the lifting method (crane, gantry, jacking system) and the assessment will reference the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), covering lift planning, exclusion zones and competent person sign-off.
How long does it take to generate?
Under 2 minutes. Describe the bridge type, waterway, foundation method and mechanical systems involved, and Anyrisks produces a complete, regulation-referenced risk assessment instantly, ready to download as PDF and Word.
