Temporary Works Design is a core discipline for CGL, where our expertise often creates major cost efficiencies.

Our Temporary Works Design Services

We provide a comprehensive range of temporary works design services including: 

  • Basement Propping Schemes
  • Excavation Stability
  • Observational Method
  • Working Platform

Our engineers have a proven track record of design as well as design checks for a range of projects involving retaining structures, slope/excavation stability and working platforms. Through innovative and pragmatic thinking we can save costs and programme time through a value engineered approach using a variety of software including PLAXIS 3D for finite element analysis.

Our geotechnical and civil engineers provide advice to optimise temporary works designfor piled walls, basement propping, plunge columns, king post designs, berm stability, cofferdams, tower crane foundations and working platforms as a single source of geostructural guidance. 

Our engineers can also provide temporary works structural design of capping beams, thrust blocks and corbels, and use software including CADS A3D, Steelwork Member Design (SWMD) and AdSec to develop designs. 

Basement Propping Schemes  

CGL provides a single source of geostructural guidance to optimise temporary works in construction solutions including the following:

  • Piled Walls
  • Basement Propping
  • Berm Stability

Our engineers can also provide temporary works design using software including CADS A3D, Steel Work Member Design (SWMD), and AdSec to develop designs, including:

  • Basement Propping Frames
  • Capping Beams
  • Thrust Blocks
  • Corbels

Observational Method   

CGL has experience in applying the Observational Method to assist clients in temporary works in construction and allow value engineering of bulk excavations for basements. We also tailor retaining wall support solutions to control movements in the most advantageous ways, both to construction programs and third-party requirements. 

Excavation Stability   

During our temporary works  process, it is important to ensure the safety of all workers, prevent accidents and protect adjacent developments and structures as well as the environment.  

At CGL, we undertake excavation stability services to assess and maintain the structural integrity and safety of below ground construction sites. This includes:

  • Site Assessment
  • Design Of Temporary Propping And Retaining Systems
  • Soil Stabilisation
  • Monitoring And Inspection
  • Safety Procedures
  • Coordination With Permanent Works Design
  • Emergency Response Plan
  • Regulatory Compliance

Working Platform Design    

As part of our temporary works in construction at CGL we design temporary granular working platforms for construction plots including haulage and access roads plus, hard standing areas are a necessary feature of almost all construction sites.

The design of working platforms can be critical for the safe operation of the following:

  • Large Construction Machinery
  • Cranes
  • Piling Rig
  • Tracked Excavators and more

Why Choose CGL for Temporary Works Services?

We are experienced in temporary works in construction design for the Highways Agency and Network Rail.

Our temporary works in construction and working platform designs are based on the recommendations given in industry guidelines from the HSE, Ciria, British Standards (the falsework code BS 5975:2019) and Eurocodes (where relevant).

We follow industry best practice guidance from the Temporary Works forum (TWf), of which CGL is an affiliated member, the Construction Plant-hire Association (CPA) and the Federation of Piling Specialists (FPS).

Our tailored and cost-effective temporary works in construction experts provide a complete solution in the management and implementation of temporary works. Providing support for both large contractors and smaller organisations our team are highly experienced and motivated to ensure they find the right solutions for every project.
