Fundamental PrinciplesIntegrated Project DeliveryDesign Build Project DeliveryMutual respect and trust Mutual respect and trust Mutual risk and rewardCollaborative innovation and decision making Collaborative innovation and decision making Early goal definition Early involvement of all key participantsIntensified Planning Open and enhanced communication

IPDDBProsConsProsConsCollaborative teamX Target cost/value design Speed X Design choices are typically limited Early decision-making X Shared risk, reward, contingency Consolidated cost risk held with the Design Builder X Decision making process is accelerated Dynamic cost modeling X Larger team Owner staffing requirement is reduced Advanced technical coordination Reduce RFIs COs and total cost

When evaluating risk, risk can be defined as the likelihood (probability) versus consequences. Setting up the acceptable level of risk in various areas, likelihood of proposed scenarios and acceptability of their consequences can be illustrated in the form of a matrix

Unforeseen conditions Site work moved to critical path



The process for creating the weekly work plans will be as followed:

Monday Update the project schedule Tuesday Develop the future schedule Wednesday Update the schedule if necessaryThursday Distribute the weekly work plan for the following week to foremen, so they can prepare for the next weeks work



It is recommended to use the Last Planner
