Temporary & Enabling Works

Temporary Works Design & Analysis

We provide full-scope temporary works services including:

 
• BS5975 compliant temporary works design
• Category 0 to 3 design checking
• Optimised construction sequencing and methodology advice
• Site liaison, RAMS review and attendance at safety coordination meetings
• Contractor Responsible Engineer (CRE) services on major infrastructure projects

With extensive varied experience, our engineers deliver reliable, safe and cost-effective solutions for high-risk and complex construction environments.

Geotechnical Temporary Works

From simple trench shoring to multi-level basement propping systems, we design robust ground retention systems tailored to each site’s geotechnical and logistical constraints. Our team works closely with contractors to integrate preferred supply chains and optimise both safety and cost-efficiency.
 

Services include:

 
• Cantilever and propped sheet pile designs, including service support design, timber lagging and thrust blocks
• Excavation stability assessments
• Temporary slope and rock cutting analysis
• Third-party design verification and checks
• Working Platform Design and optimisation using geogrids and low-carbon materials
• Buried service assessment and service protection design
• Cable pulls for installation of new services

Site Access & Enabling Works

We support the construction phase by designing all necessary enabling works, from temporary access infrastructure to contractor compounds:

 
• Temporary bridges and crossings
• Haul road design, including route selection, swept path analysis and abnormal load assessments.
• Hoarding design (semi-permanent or ballasted systems)
• Tower crane base design
• Temporary welfare setup
• Structural propping and stabilisation for adjacent or retained structures

Structural Support Temporary Works

We support the construction phase with the design of structural solutions which can include the following:

 
• Façade retention
• Propping and needling designs for structural alterations
• Formwork design
• Structural assessments of existing buildings for temporary loadings
• Falsework design
• Structural inspection reports for installed temporary works
• Scaffold design in accordance with TG20:21
• Bridge propping to reinforce or reform existing structures

Network Rail & Highways Temporary Works

We understand the technical and regulatory requirements associated with infrastructure interfaces. Arthian provides a full design service or Category 3 (Cat 3) independent design checks in accordance with BS 5975:2024 and acts as CRE when construction affects Network Rail assets. We also support:

 
• Form C preparation and design assurance documentation
• Interdisciplinary coordination for temporary works impacting highway structures
• Design verification for investor and regulatory due diligence
• Approvals negotiation with highway authorities.

Dismantling, Demolition & Destruct Engineering

Arthian offers integrated demolition design strategies, focused on delivering safe, phased dismantling while maximising asset recovery and minimising disruption. Whether the aim is clearance, reuse or sale of equipment, our structured engineering approach reduces closure costs and supports client business continuity.
 

Our demolition engineering services include:

 
• Asset condition surveys
• Reverse-engineered dismantling strategies
• Engineering for isolation and decontamination
• Environmental impact assessment and waste management
• Temporary stability bracing and propping
• Design of phased demolition sequences

We’ve successfully delivered safe outcomes in hazardous industrial, nuclear and energy environments, where safety, technical compliance and stakeholder confidence are paramount.
