delivery methods

IPD can deliver your project one of several ways, each having its own benefits. Below are the four most common delivery methods we use.  The descriptions provide a high-level overview of how each method works.  We encourage a discussion with us to determine the best path forward for your project.  So give us a call!


Considered the ‘traditional’ model. The design team usually contracts directly with the owner to generate sealed construction documents that are issued to multiple contractors for competitive bidding. The owner selects the contractor they wish to work with. The design team usually continues with construction administrative services to the owner, often overseeing construction to verify the contractor is building in accordance with the design documents.


Most often involves the owner contracting with a single entity, usually the contractor, to deliver a project in its entirety.  The design team is most often hired by the contractor.  Interactions between the design-build team and the owner are usually coordinated through the contractor.  The drawings are sometimes less detailed than a design-bid-build project, but not always.


Similar to design-build, except the design firms are hired by the contractors or their sub-contractors to provide specific design services, sometimes up to and including sealed construction drawings.  The drawings are usually less detailed than a design-bid-build project.

Permit lEvel Design

Regardless of who’s hiring the design team, the deliverables are focused on code compliance with enough content provided for the stamping professional to feel comfortable sealing the drawings.  Finite project details and coordination between trades are often not included.

Tailored Solutions
Every client has unique goals, each project is different, and all building renovation projects have challenges. Therefore, our design approach focuses on truly understanding each client’s needs, developing tailored engineering systems per client goals and building constraints, and collaborating to find the best possible solutions for each client.
Technology & Visualization
Keeping up to date with the latest technologies is critical to project success. Our team uses Building Information Modeling (BIM), which allows our clients to preview system configurations and equipment arrangements before construction begins. Using BIM clash detection, our team can identify potential issues during the design phase, reducing costly change orders during construction. With a firm grasp on evolving technologies, our innovative solutions deliver long-term value and ROI to our clients.
System Reliability & Longevity
We are committed to designing reliable systems. We design energy-efficient systems that hold up over time, reduce negative impacts on the environment, and improve human health and the comfort of the building occupants.
Energy Efficiency
Energy efficiency and sustainability are core to our mission. We take an active role on projects to help owners make informed decisions regarding system selections and work to find the right balance between efficiency and budget.
