CTS Group is hiring BIM Specialist Quantity Surveyors across Junior, Intermediate, and Senior levels to support cost management, BIM-based measurement, procurement, commercial management, and cost reporting across data centre and mission-critical projects in the EMEA portfolio.

Depending on seniority, responsibilities range from supporting 5D quantity take-off, BOQ preparation and valuations to independently managing work packages and, at Senior level, owning project-wide cost strategy, commercial risk, forecasting, client/vendor negotiations, and mentoring QS teams.

Key Responsibilities

Perform and/or lead 5D quantity take-off and measurement from Revit/IFC models using Navisworks Quantification, Autodesk Takeoff and CostX, validating model completeness and LOD suitability.
Prepare and maintain Bills of Quantities (mapa de quantidades), measurement schedules, cost estimates and cost plans across design stages.
Maintain cost data, rate libraries and commercial registers.
Support or lead procurement activities, including tender documentation, bid comparison, analysis, levelling and award recommendations.
Assess and certify interim valuations and subcontractor payment applications;
measure, value and agree variations and change orders.
Produce cost reports, forecast final cost, track committed cost, risk and contingency, and manage Cost/Value Reconciliation (CVR) .
Manage subcontractor/vendor measurement, valuation, package-level commercial risk, claims and final accounts.
Support procurement of long-lead critical equipment including chillers, generators, UPS, switchgear and transformers , including vendor pricing and milestone/payment terms.
Cross-check model-based quantities against drawings and identify model gaps or anomalies.
Maintain document control and filing within the Common Data Environment, including BIM 360 / Autodesk Construction Cloud (ACC) and Aconex .
Ensure outputs comply with the BIM Execution Plan, applicable measurement conventions, CTS and client requirements .
Apply RICS NRM / NRM2 and LNEC measurement conventions and work within ISO 19650, BEP, LOD and EIR requirements.
At Senior level, define and own cost-management and procurement strategy, approve estimates, cost plans, valuations, variations and final accounts, and own whole-project cost certainty, forecast final cost, margin and CVR.
At Senior level, lead client and major subcontractor/vendor commercial negotiations, including critical-equipment packages.
At Senior level, establish measurement and Level of Information Need (LOIN) requirements within the EIR and BIM Execution Plan to enable reliable 5D take-off.
At Senior level, lead hyperscale/colocation client cost reporting using RICS NRM / ICMS , including cost-per-MW benchmarking, cashflow/S-curves, change and risk registers, and contingency drawdown.
At Senior level, own contract and commercial risk, entitlement and claims strategy under NEC/FIDIC and GMP/target-cost arrangements .
Lead value engineering and design-to-budget strategies at Senior level.
Guide Junior Quantity Surveyors and, at Senior level, mentor and develop Junior and Intermediate QS professionals and review deliverables.
Support resourcing and commercial programme planning across concurrent packages/projects.
