About this Role

GENERAL DESCRIPTION

The 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.

What You'll Do

DUTIES & RESPONSIBILITIES

Design, Layout & Arrangements

• Develop 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 utilities
• Produce 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 material
• Develop 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 changes
• Lead interference and clash detection in the 3D model; resolve or escalate clashes before they reach the field
• Review vendor and equipment drawings for nozzle locations, connection sizes, anchor points, weights, clearances and service access, and incorporate vendor data into the model and drawings
• Apply 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 preferences

Scope Completeness, Constructability & Procure-ability

• Review OpCo and third-party deliverables for scope completeness, constructability and procure-ability; identify missing, conflicting or unbuildable scope and drive it to resolution
• Confirm scope compatibility with other advanced technology scope, systems and stakeholders. Raise questions early, discuss and explore alternatives with engineers, the client and the field
• Participate in and help lead constructability, model (30/60/90 percent) and IFC readiness reviews; document review comments and verify their incorporation
• Support 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 sequence
• Perform quality reviews of drawings and models for inaccuracies, omissions, code compliance and adherence to QDC and client standards, and provide recommendations

Engineering, Construction & Procurement Coordination

• Facilitate communication, coordination and document flow for mechanical-piping scope among the client, Quanta engineering OpCos, field execution teams and third parties
• Identify and remedy gaps between Engineering and Construction and between Engineering and Procurement; remove hurdles and resolve issues
• Coordinate equipment locations, spacing, routing, cable and pipe rack sharing, and underground conflicts with electrical, civil-structural and instrumentation disciplines and with the field
• Collaborate 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 built
• Support the Engineering Project Manager with proposal inputs, early engineering, scope definition, deliverable lists and schedules for mechanical-piping scope

Change, RFI & Documentation Management

• Review 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 finalized
• Provide 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 agreement
• Keep mechanical-piping design documentation current in the project document management system (e.g., Procore), including drawing and model revision control, as-built records and inputs to the project issue, RFI and decision logs
• Document assumptions, decisions and handoffs in writing so alignment is created by documentation rather than by meetings alone

Team Leadership, Best Practices & Lessons Learned

• Serve as lead designer for mechanical-piping scope as the QDC Engineering team grows: plan and assign design work, check drawings and models, and be accountable for the quality and schedule of the mechanical-piping design package
• Mentor designers and drafters (QDC or OpCo), review their work, and help build the QDC design standards as the team grows
• Capture lessons learned during the project; contribute to root-cause reviews of RFIs, rework and design gaps and record the methods that saved time or money
• Contribute to developing and refining QDC mechanical-piping best practices, standard details, design criteria, checklists, templates and drafting standards, and help roll them out to OpCos and project teams
• Identify scope, design, procurement and change risks early and raise them to the Engineering Project Manager with proposed mitigations, in support of the Project Risk Wheel and project risk register

Field Support & Stakeholder Relations

• Travel to project sites to walk down installations, verify field conditions and dimensions, resolve interferences, interpret drawings and support installation, startup and commissioning
• Present layouts, alternatives and recommendations in front of the client, OpCos and field leadership; represent QDC professionally in design reviews, coordination meetings and site meetings
• Be willing to speak up and ask questions; bring potential project-related problems and possible solutions to the attention of the responsible party
• Take personal responsibility for the quality and accuracy of his or her work; perform other duties as assigned

What You'll Bring
