Controls Testing Engineer

POSITION SUMMARY

• The IBMS System Architecture Expert – Design \& Estimation incumbent serves as the primary technical authority for IBMS scope definition, system architecture design, cost estimation, and technical proposal development across mission-critical data centre bids. The role demands deep expertise in Integrated Building Management Systems (IBMS), a thorough understanding of BMS/DDC/PLC controller ecosystems, and the ability to translate complex client requirements into compelling, commercially sound technical proposals.
• Working at the intersection of Engineering, Sales, and Solution Architecture, the IBMS System Architecture Expert drives technical credibility during the bid cycle — from RFP/RFQ receipt through final bid submission and post-bid technical clarification.

KEY RESPONSIBILITIES

A. System Architecture \& Scope Definition* Develop full IBMS system architecture proposals for mission-critical data center projects during the bid phase, encompassing BMS, FACP, VESDA, Water Leak Detection (WLD), Access Control, CCTV, Rodent Control, and power/environment monitoring subsystems.

• Define BMS controller platform, network topology, and integration architecture — specifying primary, field-level devices, gateways, and communication protocols (BACnet/IP, Modbus, SNMP, OPC-UA).
• Prepare detailed I/O point schedules, controller loading calculations, and scan-time calculations for DDC/PLC systems during the estimation phase.
• Design IBMS network architecture including data network topology, switch selection criteria, BACnet/IP architecture, and integration requirements for third-party systems (DCIM, EPMS, SCADA/HMI).
• Evaluate and recommend open protocol versus proprietary integration strategies, identifying technical risks and mitigations for the proposed architecture.
• Define subsystem integration requirements, API/protocol mapping, and IBMS-to-DCIM interoperability architecture for high-density and AI data center environments.

Develop control philosophy summaries and sequences of operation (SOO) drafts to support technical sections of bids, clarifying system-level control strategies without committing to detailed execution design.

• B. Bill of Quantities, Cost Estimation \& Proposal Development* Prepare comprehensive Bill of Quantities (BOQ) for IBMS scope across critical and non-critical data center projects, covering all hardware, software, licensing, integration, engineering, and commissioning cost elements.
• Develop itemized cost estimation sheets with material, labor, third-party integration, software licensing, and contingency allowances, using established Vertiv rate cards and vendor quotations.
• Produce Basis of Estimate (BOE) documents clearly defining scope boundaries, assumptions, exclusions, and unit-cost rationale for each IBMS bid.
• Benchmark IBMS costs against historical project data, vendor list prices, and market intelligence to ensure commercial competitiveness without compromising technical quality.
• Identify and quantify scope risks in estimates, recommending provisional sums and risk allowances where appropriate.
• Prepare and maintain IBMS-specific pricing matrices and parametric estimation models to accelerate turnaround for repeat bid types (colocation, hyperscale, enterprise DC).
• Contribute to internal bid review and approval processes — presenting cost models, assumptions, and risks to senior management and business development leads.

C. Technical Proposals \& Bid Documentation* Lead preparation of technical proposal sections for IBMS scope in RFP/RFQ responses, including executive summaries, technical narratives, compliance matrices, and scope clarification letters.

• Develop technical write-ups describing the proposed IBMS architecture, system capabilities, integration approach, and value differentiators — tailored to client technical and commercial requirements.
• Prepare compliance matrices mapping client specifications and standards requirements (IEC 61850, ASHRAE, TIA-942, NFPA 72, EN 54, IS 3043, NBC 2016\) against the proposed solution.
• Produce scope-of-work documents and exclusion lists that define clear contractual boundaries for the IBMS scope within the overall project.
• Develop technical clarification logs and pre-bid query registers, managing responses with accuracy and commercial awareness.
• Prepare value engineering proposals and alternative technical solutions where client requirements offer scope for cost optimization without reducing functional integrity.
• Ensure all bid documents are produced in accordance with Vertiv brand and documentation standards, with consistent formatting and professional presentation.

D. Client Engagement \& Presales Support* Act as the primary technical point of contact for IBMS scope during client pre-bid meetings, site surveys, and technical clarification discussions.

• Conduct technical feasibility assessments for proposed IBMS architectures, advising clients and the sales team on achievable scope, realistic timelines, and technical risks.
• Prepare and deliver technical presentations, solution overviews, and IBMS architecture demonstrations to client technical teams and procurement stakeholders.
• Participate in pre-bid site walks, capturing existing infrastructure constraints, network connectivity requirements, and integration opportunities.
• Support post-submission technical discussions, clarifications, and negotiation of technical scope with clients and consultants.
• Build and maintain trusted technical relationships with key clients, consultants, and specifiers in the data center and critical infrastructure markets.
• Provide technical input to sales team's go/no-go assessments, identifying bid qualification criteria and scope risks early in the sales cycle.

E. Internal Collaboration \& Presales Standards* Collaborate with Sales, Solution Architecture, Project Management, and Commercial teams throughout the bid lifecycle, ensuring aligned scope,
