Integrated Project Delivery (IPD)
“Integrated Project Delivery (IPD) integrates people, systems, business structures and practices into a process that collaboratively directs the talents and insights of the Owner, Architect, and Construction Manager, to optimize project results, reduce construction material waste, and maximize efficiency through all phases of design, fabrication, and construction processes.”
Traditional Design-Bid-Build Model (T)
The Owner selects and hires an architect. In turn, the architect retains specialized consultants, such as civil, structural, mechanical, electrical & plumbing engineering to prepare Construction Document drawings for select general contractors to bid. Establishing an accurate construction budget at the beginning of a project is difficult; therefore, conflicts may arise if the Owner’s construction budget or project schedule is not accurate. The traditional design-bid-build project delivery model often results in adversarial relationships between Owner, Architect, and Contractor.

Integrated Project Delivery Model (IPD)
The Owner, Architect, and Construction Manager enter a written agreement at the beginning of the project. A common project vision is created, along with roles and responsibilities, and a realistic construction budget and schedule is prepared by an experienced construction manager. Early in the project, the architect initiates communication with local planning and building agency authorities and specialized consultants, to identify and plan a strategy to overcome obstacles. As the Conceptualization Phase is initiated, the architect receives valuable construction cost feedback from the construction manager, to align the design concept with anticipated construction costs. This coordinated team effort provides opportunity to continuously align design solutions with anticipated construction budget. As the design progresses, many challenging obstacles are worked-though by the architect and construction manager, to promote a smooth-flowing Construction Phase.
Integrated Project Delivery Model (IPD) - The diagrams above are obtained and modified from the AIA California Council’s “Integrated Project Delivery.” New phase names are also introduced.
Architect As Developer Strengthens Integrated Project Delivery Model
Parabola A+D expands beyond architecture boundaries, to oversee and coordinate the entire development process. Working as one interdisciplinary team, we invite and combine insights and talents of several specialized disciplines, focusing on one clear vision: To deliver the highest level of uncompromised design and construction quality solutions for owners and building occupants, combined with the highest financial investment return.
Parabola A+D strategically positions the architect as developer at the center, to lead and coordinate all six phases of the development process.
Integrated Project Delivery (IPD) Workflow Model
The Parabola A+D Workflow Model expands radially, from the central starting point to the outer edge of Operations & Management. It describes estimated start-up and completion of each discipline, within specific phases of the project. The Owner, Architect, and Construction Manager actively participate in sharing responsibilities. Two primary benefits are derived with an IPD model:
The integration of early input from the construction manager, installers, fabricators, and suppliers
The ability to model the project accurately using 3-D computer modeling tools are shared with the design team and construction manager for early construction cost evaluation
Re-thinking typical project design phase, as defined by the AIA California Council, for Integrated Project Delivery (IPD):
Conceptualization (IPD) | Pre-Design (T)
Criteria Design (IPD) | Schematic Design (T)
Detailed Design (IDP) | Design Development (T)
Implementation Documents (IPD) | Construction Documents (T)
Agency Coordination/Final Buyout (IPD) | Agency Permit & Bidding (T)
Construction (IPD) | Construction Contract Administration (T)
Closeout (IPD) | Closeout (T)
The first three phases of the integrated project: Conceptualization, Criteria Design, and Detailed Design involve more effort than the traditional design-bid-build model.

Architects work directly with subcontractors to reduce construction cost for periodontal surgery building…
Our design solution increased construction quality, while lowering construction costs. Since the project was designed during the Great Recession, we developed a very creative strategic design strategy to meet the Owner's construction budget.
Working with local lumber yard reduces construction costs, without sacrificing design and construction quality…
This private residence embraces the elements of nature, wrapping itself around an open–air, south–facing courtyard. The courtyard, extending to the lower level, dissolves the concept of a dark basement.
