Responsibilities
- Adhering to NDBS Core Values
- Develop the mechanical design on assigned projects from the basis of design and P&IDs through milestone reviews and issued-for-construction (IFC) drawings
- Perform heat load, hydraulic, psychrometric and pipe sizing calculations, and select equipment such as chillers, air handlers, pumps and CDUs
- Prepare drawings, schedules, details and Revit models, and run Navisworks clash detection with other disciplines
- Coordinate day-to-day with plumbing, structural, electrical, civil and controls designers and sub-consultants, and bring open issues to the Lead Engineer
- Draft sequences of operation and support controls partners on PLC logic and Building Management Systems
- Track deliverables, engineering hours and review comments on assigned work, and report status to the Lead Engineer
- Design data center cooling systems, including chilled water plants, CRAH/CRAC units and fan walls, economizers and containment, applying the redundancy (N+1, 2N, concurrent maintainability) set in the basis of design
- Support liquid cooling design for high-density and AI workloads, including CDUs and technology cooling system (TCS) and facility water loops
- Design HVAC, process exhaust, compressed air, boiler and hot water systems, and size natural gas, process and utility piping for industrial facilities
- Prepare RFIs to close gaps in owner and process-equipment data
- Assign and schedule work for the Design Engineer, and set clear expectations for scope, quality and deadlines
- Check calculations, drawings and models
- Coach the Design Engineer on design methods, codes, software and NDBS standards, and give regular feedback on performance and development
- Identify where prefabricated pipe spools, skids and modules add value and design them for constructability and repeatability
- Confirm design concepts early so prefabricated piping can be released without rework
- Review and witness factory acceptance tests and support commissioning and integrated systems testing
- Take part in internal turnover meetings and help define scope, schedule and resources for assigned work
- Support preconstruction with design quantities and scope reviews for estimating
- Review trade-partner submittals and draft RFI responses for Lead Engineer approval
- Attend coordination meetings with owners, general contractors and trade partners, and use Procore and Autodesk Construction Cloud to manage documents
- Support quality control through site visits, field verification and punch lists
