This document outlines the implementation of a Target Cost Experiment for the construction of the Science Building at Will C. Wood High School, authorized under California Education Code 17406. It delves into the advantages of the “Lease-Leaseback” procurement method, which allows for greater flexibility in public school construction by mimicking private-sector negotiation practices. The report discusses the collaboration between owners, contractors, and architects under integrated project delivery, emphasizing the importance of design alternatives, cost implications, risk identification, and transparent decision-making throughout the project.

Capital Program Management’s Target Cost Experiment on the Will C. Wood High School Science Building Michael Flores Jay Davison
California Education Code 17406 • Authorizes “Lease-Leaseback” procurement for public school construction • Effectively takes projects out of public sector contracting restrictions • Contracts resemble a private sector negotiated GMP contract

Design-Build MEP “Vacaville U.S.D. intends to select qualified Design-Build subcontractor’s for Mechanical, Electrical and Plumbing work to work as part of an Integrated Project Delivery Team (“IPD Team”) with the Architect, Program Manager, Lease/Lease-Back Entity and the District throughout the design & construction process. All team members will be expected to collaborate and openly share information for the benefit of the Project.”
Design-Build MEP Key questions for Design-Build Subcontractors: • How soon can the D/B Contractor provide GMP? • What is the cost premium for GMP? • How can that premium be reduced? • How do we identify risk? Can it be shifted? • Who will make commitment to carry the identified risk?
