Design and Construction Integration Manager

Mott MacDonald•Seattle, WA

2d•$185,000 - $226,000•Hybrid

About The Position

Mott MacDonald is seeking a Design & Construction Integration Manager to connect the owner, final-design team, and construction delivery partners on a major program. In this senior owner-side role, you will convert design intent, contractor preconstruction input, commercial decisions, and third-party constraints into coordinated work packages that can be credibly priced, procured, staged, and built. You will lead contract-packaging strategy, constructability and staging, design-readiness gates, and interface control from final design through early construction. You will make sure contractor advice is resolved and reflected in design decisions before unresolved access, temporary-works, utility, systems, and cross-package issues migrate into the field.

Requirements

Bachelor's degree in engineering, construction management, architecture, project management, or a related field.
Significant experience leading design-construction integration on a major transit, rail, or heavy-civil program from preconstruction through a target-price, GMP, or MACC commitment and into construction.
Experience coordinating multidisciplinary design, commercial, controls, construction, systems, utility, and third-party teams across multiple contract or work packages.
Strong knowledge of final design, constructability, preconstruction services, early-work packaging, procurement, cost and schedule development, temporary works, access planning, and construction sequencing.
Demonstrated experience defining and closing physical, functional, organizational, and temporal interfaces; resolving scope gaps and dependencies; and documenting the disposition of contractor input and owner decisions.
Strong communication, workshop facilitation, negotiation, conflict-resolution, and partner-coordination skills, with the judgment to escalate issues early and clearly.
Working knowledge of integrated master scheduling, independent estimating, risk and contingency management, change control, procurement, and collaborative-delivery commercial governance.

Nice To Haves

Professional Engineer, Certified Construction Manager, Project Management Professional, or comparable professional credential.
Direct owner-side or contractor-side experience with Washington GCCM, GC/CM, CMAR, or progressive design-build, including preconstruction services, estimate reconciliation, and MACC or GMP development.
Experience supporting major transportation, transit, rail, or complex civil infrastructure programs.
Advanced knowledge of construction staging, temporary works, systems and civil interface control, configuration and design change management, package-release readiness, and testing

Responsibilities

Build the connection between design and construction. Lead integration across complex infrastructure work packages so design information is coordinated, constructible, ready for pricing, and aligned with delivery schedules.
Serve as the owner-side integration lead among the final designer, GCCM and other construction delivery partners, commercial management, project controls, systems integration, third parties, and field delivery teams.
Develop and maintain contract packaging strategies, including early works and major construction packages.
Lead structured constructability, access, staging, temporary-works, logistics, and means-and-methods reviews; convert contractor input into assigned design actions with documented disposition and closure.
Integrate GCCM preconstruction deliverables with design development, independent estimating, procurement, risk retirement, sequencing, and construction execution, including estimate and schedule reconciliation at commercial commitment points.
Establish and administer design-readiness and package-release milestones based on scope definition, quantities, interfaces, permits, access, retained risks, third-party commitments, and pricing assumptions, not design percentage alone.
Own interface control across civil, stations, track, rail systems, utilities, structures, and third-party work packages, including tie-ins to existing and adjacent infrastructure.
Identify and resolve scope gaps, overlaps, owner-retained responsibilities, access dependencies, acceptance criteria, and cross-package risks before they affect procurement, pricing, construction, testing, or commissioning.
Align design deliverables and interface-closure dates with the integrated master schedule, procurement milestones, early-work releases, and commercial decision points; escalate unresolved issues with clear cost, schedule, risk, and operational consequences.
Maintain the integration plan, interface register, design-readiness dashboard, assumptions and commitments log, decision log, action register, and records showing contractor recommendations that were accepted, rejected, deferred, or transferred.
Embed safety, quality, maintainability, operability, and construction-readiness requirements in design and preconstruction decisions, while promoting early bad news, timely resolution, and continuous improvement.
