Integrated Project Delivery (IPD)
  • Highly collaborative, team-based delivery model.
  • Owner, designer and builder work together from early design through construction.

  • Andersen works closely with design partners to deliver an integrated solution.
Negotiated Guaranteed Maximum Price (GMP)
  • Collaborative pricing approach where the team works toward a defined scope and schedule with a negotiated guaranteed maximum price.

  • Focus on planning, reducing waste, improving flow of work and enhancing value for the owner.
  • Collaborative processes are used across delivery methods to support predictable outcomes on complex projects.

Preconstruction Philosophy

The decisions made in preconstruction are treated as critical to a project's overall success. Andersen's preconstruction process is described as highly collaborative and more than just reactive estimating.

  • Preconstruction is a core strength and a constant focus across all Andersen locations.
  • The team engages early with owners and design partners to plan each project in detail.
  • Emphasis on identifying project goals, constraints and risk early in the process.

Scope of Preconstruction Services

Preconstruction services typically include:

  • Collaborative planning and project definition.
  • Budgeting and cost estimating throughout design.
  • Constructability input and options analysis.
  • Scheduling and phasing strategies, including work on occupied campuses.
  • Coordination with key trade partners to align scope, schedule and budget.

Integration With Delivery Methods

Preconstruction is integral to Andersen's primary delivery methods, including:

  • CM/GC and GC/CM
  • Negotiated GMP
  • Design-Build
  • Integrated Project Delivery (IPD)

A large majority of the projects highlighted in Andersen's portfolio include full preconstruction services, reflecting how central this phase is to the company's approach.
