Explore implications of Design-Bid-Build (DBB), Design-Build (DB), and Integrated Project Delivery (IPD) methods in construction and IT projects. Learn about advantages, disadvantages, and challenges in shared risk models. Understand the impact on project outcomes and stakeholder engagement.
E N D
Implications - DBB • Architect develops and complete bid documents prior to construction review • Project has a short and discrete bid phase • Contractor constructs project based on contract • Rigid change process • Client/Owner has limited involvement after design
Implications - DB • Architect develops and complete construction documents collaboratively • Project has no bid phase • Contractor and Architect share benefits • Collaborate change process • Client/Owner has limited involvement in design
Implications - IPD • All parties have same level of risk • IPD Agreement must be signed prior to project initiation • Architect, Contractor, and Client/Owner share benefits • Collaborate change process with all parties
IPD Advantages • Construction Projects • Common goals that are agreed in advance between the Architect, Contractor, and Client/Owner • Shortened feedback loop • Shared risks provide incentives to resolve conflicts and complete project • End goal is the focus vs. financial gain • Reduced project waste • Reduced schedule time • IT Projects • Common goals that are agreed in advance between the Designer, Developer, and Client/Owner • Shortened feedback loop • Shared risks provide incentives to resolve conflicts and complete project • End goal is the focus vs. financial gain • Reduced project waste • Reduced schedule time
IPD Disadvantages • Construction Projects • Architect and Client/Owner have increased risk levels compared to DBB • Less individual accountability amongst parties • Increase reliability on Client/Owner • Increase susceptibility to scope creep • Architect has higher financial risk • Contractor has less opportunity to make additional profits • IT Projects • Designer and Client/Owner have increased risk levels compared to DBB • Less individual accountability amongst parties • Increase reliability on Client/Owner • Increase susceptibility to scope creep • Designer has higher financial risk • Developer has less opportunity to make additional profits
Challenges • Early commitment from all parties • Trust • Frequent meetings, coordination and collaboration • IT Projects conducted in virtual job sites • Reliance on arbitration and cooperation over legal recourse • Requires modeling technology • Construction projects require rapid visual models • IT projects require rapid workflow and data modeling • Change process requires rapid evaluation and decision making • Achieving waste reduction without increasing the project scope or project schedule • High tech and standardized technology across all parties
