Specialist Site Works

Access and enabling works built around the project.

Modular pontoons, culvert and watercourse works, rope access, confined-space support, rescue provision and temporary flow management—planned around the task, site conditions and wider delivery strategy.

Specialist Project Delivery Capabilities

The access method follows the work.

CRM first establishes the workface, intended outcome, operating restrictions, environmental controls, temporary works interfaces and rescue requirements. The site solution is then developed around what is practical and proportionate.

Modular pontoons

Working platforms, floating access, edge protection, site-specific configurations, installation and management.

Culvert & watercourse works

Access, cleaning, desilting, debris removal, examination-enabling works and temporary working areas.

Specialist access

IRATA rope access, temporary platforms, PASMA access and arrangements for difficult or restricted locations.

Confined-space support

Entry planning, access support, communications, supervision and rescue arrangements for culverts, tunnels and chambers.

Water rescue

Safety cover and task-specific rescue provision coordinated around water-based access and the proposed methodology.

Temporary flow management

Temporary dams, phased dewatering, pumping strategies, environmental controls and practical operating thresholds.

Modular Pontoons & Water-Based Access

Wherever land and water meet.

CRM provides modular pontoon working platforms and floating access for rail assets, bridges, culverts, canals, waterways and waterside construction.

Where permissions are required, CRM also coordinates environmental permit and statutory consent requirements, specialist assessments, environmental controls and delivery sequencing so the access solution is connected to the wider project plan.

Working platformsStable work areas for examination teams, maintenance activities, temporary towers and specialist operations.

Site-specific arrangementsPlatform size, layout, edge protection, access points and positioning developed around the task and location.

Installation & managementMobilisation, assembly, movement and site control coordinated as part of the agreed delivery method.

Culvert & Watercourse Works

Creating the access and conditions required for the next activity.

CRM undertakes practical culvert and watercourse works including access, cleaning, desilting, debris and vegetation removal, temporary platforms, flow management and environmental controls. Where asset examinations are required, CRM establishes the access and working conditions for the client's appointed examination team.

Where applicable, CRM coordinates environmental permit applications, Natural England Assent information, HRA or sHRA and WFD inputs, environmental risk assessments and regulatory liaison alongside the methodology, temporary flow planning and delivery sequence.

Access, flow, environment and rescue considered together.

Culvert work can involve uncertain internal conditions, restricted clearances, water, silt, gas release, long rescue distances and limited communications. CRM develops a proportionate route around the actual conditions rather than forcing a predetermined access technique.

Confined Space & Water Rescue

Rescue arrangements connected to the method.

CRM supports confined-space and water-based activities with entry planning, communications, safety cover and task-specific rescue arrangements. The provision is developed around the location, access route, personnel and intended work.

Proportionate specialist supportCRM develops proportionate, task-specific rescue support and coordinates more complex provision with an appropriately competent specialist rescue partner where required.

Specialist Access

Developed around the environment—not a list of techniques.

Above-ground access, water-based access, confined spaces and restricted locations each require different controls. CRM selects and develops the access arrangement around the task, site conditions, safety considerations, rescue provision and temporary works interfaces.

IRATA rope accessQualified technicians for locations where conventional access is unsuitable or disproportionate.

Temporary access platformsModular pontoons, PASMA arrangements and other task-specific work areas where appropriate.

Examination & maintenance accessPractical enabling support for the client's appointed technical or examination team.

Rail Infrastructure Support

Specialist access, enabling works and practical site support.

CRM supports Principal Contractors, asset examination teams, delivery partners and maintenance contractors with modular pontoon access, rope access, confined-space support, water rescue, temporary access platforms, environmental planning and specialist logistics.
