About This Role
GENERAL DESCRIPTION The Senior Lead Mechanical Engineer is the mechanical discipline lead on the QDC Engineering team, responsible for the technical completeness, technical compatibility and buildability of mechanical scope on fast-track, advanced technology projects. On these projects the major mechanical equipment, water-side and air-side, is typically owner furnished and contractor installed (OFCI), and Quanta installs the equipment and the interconnecting piping and connections that tie it together. The Senior Lead Mechanical Engineer therefore owns two things: the technical integrity of the interconnecting mechanical piping systems (chilled water, condenser water, technology cooling water, fuel oil, makeup water and related utility systems) and the integration of owner-furnished water-side and air-side equipment into those systems and the facility, reviewing vendor data against the system design and the client's basis of design and raising what is off before it reaches the field. In QDC's current delivery model the detailed design is performed by Quanta engineering OpCos and third-party engineers of record; the Senior Lead Mechanical Engineer provides technical oversight of that work, sets and enforces QDC design criteria, reviews calculations, drawings and specifications, and asks the questions the designer cannot: is the system complete, does it work with the equipment and the rest of the project, and will it flush, test, start up and operate the way the client expects. The Senior Lead Mechanical Engineer reports to the (Sr) Engineering Project Manager, QDC, supports all projects in the division, works hand in hand with the Senior Lead Mechanical-Piping Designer, and serves as the mechanical technical point of contact between Engineering, Procurement, Field Operations and the client from proposal and early engineering through detail design, construction, startup and commissioning. As the QDC Engineering team grows, this position is expected to lead the mechanical discipline, planning, assigning and reviewing the work of QDC engineers and designers.
What You'll Do
DUTIES & RESPONSIBILITIES Piping Systems & OFCI Equipment Integration Develop and maintain QDC mechanical design criteria and the project basis of design for the interconnecting piping systems, including system topology and redundancy, design pressures and temperatures, flow and head requirements, piping materials and specifications, valve and specialty requirements, insulation, and flushing, cleaning, testing and commissioning requirements Develop or review P&IDs, flow diagrams, hydraulic calculations, pipe sizing, pump and system curve checks, expansion and makeup provisions, and piping material and valve specifications for chilled water, condenser water, technology cooling water, fuel oil and related utility systems; confirm the system delivers the flows, pressures and redundancy the equipment and the client require Review owner-furnished mechanical equipment, water-side (chillers, cooling towers and dry coolers, pumps, heat exchangers, CDUs and similar) and air-side (CRAHs, fan walls, air handlers and similar), against the piping system design, the facility interfaces and the client's basis of design, using vendor drawings, data sheets, performance curves, connection schedules and installation requirements; identify mismatches in piping and coil connections, condensate and drain provisions, duct and plenum interfaces, flows, pressure drops, capacities, clearances, rigging and sequencing, and raise them to the client, the OEM and the OpCos with recommended resolutions Understand and apply the piping engineer's stress analysis, anchor, guide and support requirements to the system design and the structural and equipment interfaces, and know where ASME B31 analysis is required, without performing the analysis Prepare or review specifications, data sheets and technical requisitions for contractor-furnished mechanical scope (piping, valves, specialties, insulation, pumps or skids where Quanta furnishes them), and lead technical bid evaluations and vendor submittal reviews for that scope Apply applicable codes and standards (for example ASME B31.1, B31.3 and B31.9, ASHRAE standards and the Datacom series, IMC/UMC and NFPA 30 and 37 for fuel systems) and client design criteria; identify deviations, requirements versus preferences,
