A unique project delivery method was started in Los Angeles in 1984, for the construction of a Four Seasons Hotel in Los Angeles, by Anthony Mason of AMAPM. At the time, the traditional Design-Bid-Build (D/B/B) approach was not working due to disagreements among the project team, the client's inexperience and the inherent misaligned priorities of the stakeholders.[1]
To address these challenges, a new method called "Intent of Design" IGMP/GMP was implemented. The “IGMP/GMP method” was later identified as the IPMA method, taught at the GSD from 2011 to today, 2024. This method involved integrating the General Contractor (GC) earlier in the design process and using schematic stage drawing estimating based on intent of designs, with collaboration of the Architects and Engineers to support the competitive GC bidding during bid-phase of the GC selection process. The GC would then provide an initial Guaranteed Maximum Price (GMP), which guaranteed the construction cost to not exceed the IGMP for the project for a similar scope when bid at the Construction Documentation stage. This approach allowed for collaboration and cost control throughout the design phase.[2]
The new IGMP/GMP method also involved competitive subcontractor bidding at 100% of the Design Development stage of drawings, to confirm the final GMP. With the selection of the right architect and the right GC working in collaboration, project team would then work with open-book together to create a complete set of drawings, in order to aid the selection of subcontractors and finalize the GMP. This process ensured the Owner would benefit the most with a project that allowed transparency, developed a successful proto-typical project with minimized risks for all parties involved.[3]
To highlight the success of this alternative method, it was used on over 120 projects since then and has been documented by Harvard University. The method is now known as the Integrated Project Management Approach (IPMA) and is currently taught at Harvard Graduate School of Design.[4]
