Station Scaffold Design

Temporary Works Design

Project Commenced: October 2020

Project Completed: December 2020

Client: Network Rail

 

About the Project

As part of the CAPEX framework, BCM Construction were engaged by Network Rail to undertake refurbishment works of various station buildings in the South East region. These works included repointing and painting of facades, works to existing gutters and works to canopy rooves and dagger boards. To undertake these works in a safe manner, for both operatives and the general public, scaffold access platforms were proposed, wrapping around the station buildings. 

BCM Construction looked to Equate Design to provide the Design Assurance to ensure that the specialist scaffold designs were safe and complied with Network Rail Standards, particularly where erected on open platforms. 

Within this remit, Equate design undertook the role of Civils Design CRE, liaising between the scaffold designers and construction teams, and coordinating and compiling the F002 and F003 Temporary Works submissions in accordance with NR/L2/CIV/003. 

The Challenge 

Whilst a competent scaffold designer is capable of producing a design for a scaffold that is fit for purpose in terms of access provision, without a detailed knowledge of Network Rail standards there are multiple ways that a scaffold can interfere with the safe passage of trains, or could impede passengers using the station, potentially putting them in a dangerous situations.  

The Solution 

By engaging Equate Design to fulfil the Civils Design CRE role it gave BCM Construction the confidence that the design submission process would flow smoothly in a timely fashion, and that the final design would be a safe and practicable solution. 

The review process focused on several areas including signal obscuration, passenger access and useable platform widths, DDA access to the platforms, and the interface with moving vehicles outside the station. 

Most design issues were resolved, however more significantly, there were several schemes where the original proposals required significant alteration to achieve full compliance. 

 

The Deliverables: 

  • Design Assurance – Equate Design undertook the Civils Design CRE role to ensure Temporary Works F002 and F003 submissions were compliant with Network Rail standards and the design process was managed in accordance with NR/L2/CIV/003 
  • Designs that included scaffolding on platforms were reviewed to ensure there were no signal obscuration issues, and pedestrians could safely use the platform, including checks that scaffold legs were the requisite distance back from the platform edge. 
  • Checks were undertaken to ensure that staff and passengers had clear visibility of signage, notices and information boards. 
  • Platform construction was reviewed to ensure it was capable of supporting the scaffold leg loads, and any below ground structures (such as subways) were identified and assessed for the proposed loading. 
  • Scaffolding located near vehicular access routes were assessed to determine if additional vehicle impact barriers were required, whether a safe pedestrian walking route was maintained, and that all areas were accessible to wheelchair users. 
  • Full Designers Risk Assessments and Design Decision Logs were undertaken to ensure compliance with the CDM Regulations. 
  • Scaffolding designs were reviewed, and areas for additional structural assessment were identified, such as existing rooves which were to support scaffolds providing access to chimney stacks. 

 

Outputs and Benefits:

Compliance: Whilst specialist scaffold designers should be capable of providing a safe scaffold, they frequently do not have sufficient knowledge of the various Network Rail Standards that relate to stations, and station platforms. Equate Design were able to provide this specialist knowledge, coordinating the design and ensuring compliance with the relevant standards, and a smooth transition through the design approval process.
