Temporary Works Design for Fall Restraint System in Hull

Client: Sword Construction UK Ltd

Location: A63 Castle Street

Project overview

Amrose Associates was appointed as temporary works designer to develop a fall restraint system to support a road scheme in Hull where National Highways is creating a new junction, lowering the level of the A63 Castle Street to create a split-level junction.

During the works, operatives would need to work close to an exposed edge next to an existing capping beam. To carry out these activities safely and in line with UK standards, a temporary fall restraint system was needed that could be installed, tested and managed within a live construction site.

Our role

We delivered the full temporary works design for the fall restraint system, supporting Sword Construction through design development, risk assessment and site implementation.

The design included a 15-metre temporary horizontal lifeline, set up as a fall restraint system to prevent operatives from reaching the edge, rather than relying on fall arrest. The system was tailored to the site layout, with clear limits and controls for safe use:

  • General Arrangement drawings were produced to show the system layout, anchor points, clearances, exclusion zones and expected line movement under load. These formed part of the temporary works documentation and supported safe installation and day-to-day use.
  • Key system limits were clearly defined, including a maximum user weight of 200kg and controls on the number of users at any one time.
  • A Design Risk Assessment was also provided, identifying key risks such as misuse, overloading, ground conditions and inspection requirements, along with appropriate control measures.
  • The design was developed in line with BS EN 795 and BS 5975-1:2024, ensuring it could be managed safely within the project’s temporary works procedures.

Our approach

The fall restraint system was designed as a managed engineering solution. The focus was on preventing operatives from reaching the edge, rather than relying on interrupting a fall once it had happened.

The design approach included:

  • A clear distinction between fall restraint and fall arrest
  • Defined exclusion zones and clearance requirements, based on predicted line movement under load
  • Integration with the contractor’s Safe System of Work, inspection regime and permit-to-load procedures
  • On-site testing to confirm design assumptions and verify the operational 15-metre span

This approach meant the system could be safely installed, managed and used with confidence in real site conditions.

Outcome

The temporary works design allowed Sword Construction to carry out works safely next to an exposed edge, without adding unnecessary complexity or delays to the programme.

The fall restraint system provided a clear, compliant solution that could be confidently installed, used and managed on site. Working-at-height risks were controlled through practical engineering design, supported by clear documentation and straightforward site controls.

This project highlights Amrose Associates’ ability to deliver temporary works designs that are technically robust and fully workable on site.
