CSA Construction Manager
Location: London, UK
Sector: Data Centres / Mission Critical
Discipline: Civil, Structural & Architectural (CSA)
Reporting to: Project Manager
Role Summary
We are seeking an experienced CSA Construction Manager to lead the Civil, Structural and Architectural construction delivery on the GC Data Centre Project.
The successful candidate will take ownership of the CSA scope from construction and installation through completion, snagging, commissioning readiness and final handover.
This is a senior site-based delivery role requiring strong experience in data centre or mission-critical construction, with particular emphasis on programme, quality, subcontractor management, coordination with MEP services and progressive area completion.
The CSA Construction Manager will be responsible for ensuring that all CSA works are delivered safely, to the required quality, in accordance with the project programme and fully coordinated with Mechanical, Electrical, Controls and Commissioning activities.
The individual must be highly delivery-focused, capable of managing multiple subcontractors and maintaining a strong site presence to ensure that reported progress reflects the actual physical position of the works.
Key Responsibilities
CSA Construction Delivery
- Take overall responsibility for the day-to-day delivery of the CSA construction scope.
- Manage and coordinate CSA subcontractors, supervisors, engineers and specialist contractors.
- The CSA scope may include:
- Structural steelwork
- Secondary steelwork
- Equipment support steelwork
- Concrete works
- Equipment plinths and housekeeping pads
- Blockwork and partitions

- Whitewall / cleanroom-type partition systems
- Doors and access systems
- Raised Access Floors (RAF)
- Floor finishes
- Roofing systems
- Cladding and external envelope
- Waterproofing
- Fire compartmentation

- Penetrations and making good
- Plant-room finishes
- Internal architectural finishes
- External works
- Temporary works associated with CSA delivery
Ensure works are delivered in accordance with the latest approved drawings, specifications, technical submittals, BIM information and project quality requirements.
Programme & Planning
- Take ownership of the CSA construction programme and ensure works are delivered against agreed milestone dates.
- Work closely with the Planning team to develop realistic and achievable construction sequences.
- Develop and maintain:
- Six-week look-ahead programmes
- Three-week look-aheads
- Weekly work plans
- Area completion plans
- Resource forecasts
- Recovery programmes
- Snagging and close-out plans
- Monitor subcontractor progress and productivity against the programme.
- Review manpower levels and ensure sufficient resources are deployed to meet project requirements.
- Identify delays and constraints early and drive corrective actions.
- Challenge subcontractors where progress or resource levels are insufficient.
- Develop recovery strategies where works fall behind programme.
- Provide accurate progress updates based on actual site completion, rather than reported percentage completion.
MEP & Commissioning Interfaces
- A key responsibility of the CSA Construction Manager will be ensuring CSA works support rather than constrain the MEP and commissioning programme.
- Coordinate closely with Mechanical and Electrical teams regarding:
- Equipment installation routes
- Plant access
- Equipment bases and plinths
- Structural supports
- Builders' Work Openings
- Service penetrations
- Raised Access Floor requirements
- Firestopping
- Ceiling interfaces
- Wall penetrations
- Door sizes and access requirements
- Plant-room completion
- Weatherproofing
- Permanent access and maintenance requirements
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Ensure CSA areas are completed and released in accordance with the MEP installation and commissioning sequence.
Identify CSA activities that could affect:
- Equipment installation
- Energisation
- Mechanical completion
- BMS installation
- Commissioning
- Integrated Systems Testing (IST)
Drive these activities as priority works where they impact key project milestones.
Raised Access Floors
Where applicable, take responsibility for the management and coordination of raised access floor installations.
Ensure:
- Pedestal locations and fixing comply with approved details.
- Pedestals are correctly drilled, fixed and bonded where required.
- Stringers and supports are correctly installed.
- Floor levels and tolerances are maintained.
- Cut tiles are properly supported.
- Additional supports are provided around penetrations and heavy equipment.
- Load requirements are understood and communicated.
- Temporary loading and equipment movement across RAF areas are controlled.
- Completed floors are adequately protected from following trades.
- Underfloor areas are inspected and snag-free before final closure.
Coordinate closely with MEP teams regarding services installed below the RAF and ensure inspections are completed before access becomes restricted.
Builders' Work Openings & Penetrations
Take ownership of the coordination and close-out of Builders' Work Openings (BWOs).
Ensure:
- Openings match approved coordinated drawings.
- Penetration sizes and locations are suitable for installed services.
- Fire-rated walls and floors are correctly identified.
- MEP services are installed in a configuration that allows compliant firestopping.
- Non-compliant openings are identified early.
- Design queries are raised promptly where services conflict with tested firestopping details.
- BWOs are progressively released for firestopping.
Work closely with Mechanical, Electrical, BIM and Firestopping teams to prevent late-stage BWO and penetration issues.
Firestopping & Compartmentation
Manage the CSA interface with the project firestopping strategy.
Ensure:
- Fire-rated walls and floors are correctly constructed.
- Firestopping systems comply with approved tested details.
- Penetrations are appropriately prepared before firestopping.
- MEP services maintain required spacing and configuration.
- Engineering Judgements are obtained where installations fall outside tested details.
- Firestopping installations are inspected and documented.
- Fire compartmentation is maintained throughout construction.
Drive progressive completion rather than allowing firestopping to become a late-project close-out activity.
Structural & Equipment Support Coordination
Coordinate structural requirements associated with MEP equipment including:
- Equipment plinths
- Housekeeping pads
- Secondary steelwork
- Support frames
- Spreader steel
- Equipment goalposts
- Access platforms
- Maintenance platforms
