Sr Lead Mechanical-Piping Designer

Senior Lead Mechanical-Piping DesignerThe Senior Lead Mechanical-Piping Designer is a senior member of the QDC Engineering team responsible for the layout, arrangement, completeness and buildability of mechanical and piping scope on fast-track, advanced technology projects. Working across the client, Quanta engineering and construction OpCos, equipment vendors and third parties, this position makes sure the mechanical-piping scope is complete, constructable, procurable and compatible with the rest of the project scope before it is issued for construction (IFC). The Senior Lead Mechanical-Piping Designer reports to the (Sr) Engineering Project Manager, QDC, supports all projects in the division, and serves as a mechanical-piping design 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 serve as lead designer for mechanical-piping scope, planning, assigning and checking the work of QDC and OpCo designers and drafters.
Design, Layout & ArrangementsDevelop and review 2D and 3D mechanical equipment layouts, general arrangements, plot plans and piping routings for advanced technology facility mechanical systems, including chilled water and condenser water plants, CRAH/CRAC and in-row cooling, liquid cooling distribution (CDUs and technology cooling loops), cooling towers and dry coolers, fuel oil systems, generator exhaust, HVAC ductwork and associated underground utilitiesProduce and check design deliverables such as equipment location plans, piping plans and sections, isometrics, pipe support and hanger details, penetration and sleeve drawings, tie-in details and bills of materialDevelop layouts that maintain code and manufacturer clearances, maintenance corridors, rigging and pull paths, and access for operations; design in capacity for change, growth and unknowns where the added cost is low (space, dirt, concrete and steel) to protect the schedule from late equipment changesLead interference and clash detection in the 3D model; resolve or escalate clashes before they reach the fieldReview vendor and equipment drawings for nozzle locations, connection sizes, anchor points, weights, clearances and service access, and incorporate vendor data into the model and drawingsApply applicable codes and standards (ASME B31.1/B31.3/B31.9, ASHRAE, IMC/UMC, NFPA, IBC) and client design criteria to layouts and piping arrangements; flag deviations and requirements versus preferencesScope Completeness, Constructability & Procure-abilityReview OpCo and third-party deliverables for scope completeness, constructability and procure-ability; identify missing, conflicting or unbuildable scope and drive it to resolutionConfirm scope compatibility with other advanced technology scope, systems and stakeholders. Raise questions early, discuss and explore alternatives with engineers, the client and the fieldParticipate in and help lead constructability, model (30/60/90 percent) and IFC readiness reviews; document review comments and verify their incorporationSupport procurement with material take-offs, requisition inputs, long-lead equipment identification, bid evaluation inputs and vendor drawing review; flag long-lead equipment whose lead times conflict with the construction sequencePerform quality reviews of drawings and models for inaccuracies, omissions, code compliance and adherence to QDC and client standards, and provide recommendationsEngineering, Construction & Procurement CoordinationFacilitate communication, coordination and document flow for mechanical-piping scope among the client, Quanta engineering OpCos, field execution teams and third partiesIdentify and remedy gaps between Engineering and Construction and between Engineering and Procurement; remove hurdles and resolve issuesCoordinate equipment locations, spacing, routing, cable and pipe rack sharing, and underground conflicts with electrical, civil-structural and instrumentation disciplines and with the fieldCollaborate with the Senior Lead Mechanical Engineer, other discipline engineers, and other discipline designers on technical completeness and compatibility, providing designer input on how the scope will actually be builtSupport the Engineering Project Manager with proposal inputs, early engineering, scope definition, deliverable lists and schedules for mechanical-piping scopeChange, RFI & Documentation ManagementReview and respond to construction RFIs, field change requests and redlines for mechanical-piping scope as assigned by the project team; implement redlines with precision and confirm accuracy before drawings are finalizedProvide design input on the layout, equipment, material and schedule impacts of proposed changes so the project team can run them through the formal QDC change process rather than by informal agreementKeep mechanical-pipi
