For over 45 years, the Hickory name has been synonymous with exceptional craftsmanship and value, client-friendly service and on-schedule construction.
Selecting the appropriate project delivery method is one of the most critical decisions a commercial developer, corporate executive, or board of directors will make. The chosen delivery framework dictates how contracts are structured, how risks are distributed, how budgets are managed, and how quickly the building transitions from concept to occupancy.
Two primary frameworks dominate the commercial construction landscape: Design-Bid-Build (DBB) and Design-Build (DB). While Design-Bid-Build has historically served as the traditional approach to commercial development, Design-Build has rapidly grown in popularity due to its streamlined management structure and speed to market.
Choosing between these two models requires a clear understanding of your organization's priorities. Does your project require absolute architectural autonomy, or is rapid completion your primary financial driver? Are you equipped to manage separate design and construction contracts, or do you prefer single-source accountability?
This comprehensive analysis examines the contractual structures, timeline dynamics, cost behaviors, and risk profiles of Design-Build and Design-Bid-Build, helping you determine which delivery method best aligns with your commercial goals.
Design-Bid-Build is the traditional sequential approach to commercial construction. In this model, the project moves through three distinct, separate phases: design, bidding, and construction.
In a Design-Bid-Build arrangement, the property owner holds two separate prime contracts:
Because these contracts are entirely separate, there is no direct contractual relationship between the architect and the general contractor. Both entities report independently to the owner.
First, the owner retains an architect to develop schematic designs, design development plans, and final construction drawings. Once the design phase is fully complete and approved, the owner issues the construction documents to multiple general contractors for competitive bidding.
Contractors submit lump-sum price proposals based on the completed drawings. The owner evaluates the bids, typically selecting the qualified contractor with the lowest price, and signs a separate construction contract. Physical work on site begins only after the contract is awarded and permits are issued.
Design-Build is an integrated project delivery method that consolidates design and construction services under a single contract. Instead of hiring an architect and a builder separately, the owner contracts with a single entity, known as the Design-Builder.
The owner executes one single prime contract with the Design-Builder. The Design-Builder may be a general contracting firm with in-house architectural capabilities or a partnership between a contractor and an architectural firm. Regardless of the internal structure, the Design-Builder bears total contractual responsibility for both the design accuracy and the construction execution.
The owner selects a Design-Builder early in the project lifecycle, often based on qualifications, past performance, and conceptual fee proposals rather than 100 percent finished plans. The Design-Builder collaborates with the owner to establish performance requirements, budget parameters, and spatial goals.
As design concepts develop, the builder provides real-time cost estimating, material sourcing feedback, and constructability audits. Construction can often begin on early site packages (such as earthwork and foundation footings) while interior finish details are still being finalized.
Evaluating Design-Build and Design-Bid-Build requires weighing three interconnected project variables: timeline speed, cost predictability, and owner control.
Time to market is often the deciding factor for commercial developers. In a Design-Bid-Build model, project phases are strictly linear. Design takes six to twelve months, bidding adds one to three months, and construction follows. Any delay in the design or bidding phase pushes back the final completion date.
In a Design-Build model, design and construction overlap. Site clearing, grading, utility installation, and foundation pouring occur while architectural teams finish interior framing and finish details. This fast-tracking capability typically reduces overall project schedules by 15 to 25 percent compared to Design-Bid-Build.
Many owners assume that Design-Bid-Build delivers the lowest total cost because of competitive lump-sum bidding. While Design-Bid-Build may generate a lower initial bid, it frequently experiences cost growth during construction due to change orders, design omissions, and constructability delays.
In Design-Build, cost certainty is established early through a Guaranteed Maximum Price (GMP). The Design-Builder evaluates costs throughout design development, locking in material prices and trade subcontractor proposals before construction begins. While the initial contract value may reflect realistic real-world conditions rather than a low bid, total project cost growth is significantly lower under Design-Build.
The primary tradeoff between the two delivery methods centers on control versus risk allocation.
Design-Bid-Build maximizes owner control over the design product. The owner retains complete authority over architectural details and can insist on specific aesthetic choices without builder pushback. However, the owner retains the financial risk of design errors and constructability conflicts.
Design-Build transfers design liability and constructability risk to the single-source contractor. The owner surrenders some direct control over minor design details, but gains protection against change orders caused by architectural gaps.
Different commercial project types demand different delivery strategies based on complexity, funding requirements, and schedule sensitivity.
When planning specialized commercial spaces, understanding what makes luxury commercial construction different from standard commercial builds illustrates why integrated preconstruction and specialized trade coordination are essential for high-end projects.
Regardless of whether an owner selects Design-Build or a modified Design-Bid-Build approach, robust preconstruction management is the foundation of financial control.
Preconstruction serves as the bridge between concept and physical construction. During this phase, the project team conducts site due diligence, evaluates soil conditions, audits utility infrastructure, and establishes detailed budget baselines.
In a Design-Build model, preconstruction is inherently built into the single contract, allowing the builder to perform value engineering and supply chain analysis while drawings are created. In a Design-Bid-Build model, owners can achieve similar benefits by retaining a construction manager during design to perform constructability reviews before issuing plans for bid.
To prepare your leadership team for early project planning, reviewing what to expect during the preconstruction phase of a commercial project provides a clear roadmap for site evaluations, budget modeling, and scheduling.
Evaluating potential construction partners requires probing their experience with your chosen delivery method. Asking targeted questions about team structures, cost-tracking tools, and risk-management strategies is essential. Reviewing the best questions to ask before hiring a commercial builder helps board members and developers thoroughly vet general contractors before committing capital.
Selecting a contractor who aligns with your project goals ensures transparent communication and disciplined execution. Partnering with a firm guided by clear organizational standards and fiscal responsibility, as detailed in our values, protects your investment throughout design and construction.

The main difference lies in contract structure and project sequence. In Design-Bid-Build, the owner holds separate contracts with the architect and the contractor, executing design, bidding, and construction in strict linear order. In Design-Build, the owner holds a single contract with one entity responsible for both design and construction, allowing design and physical work to overlap.
Not necessarily. While Design-Bid-Build may yield a lower initial competitive bid on paper, final costs often rise due to change orders and design omissions. Design-Build establishes early cost certainty through a Guaranteed Maximum Price (GMP) and reduces expensive field change orders, making total project costs equal to or lower than traditional builds.
Design-Build is typically 15 to 25 percent faster overall than Design-Bid-Build. By overlapping the design and construction phases, contractors can begin site excavation, grading, and foundation work while architectural teams finalize interior finish details.
Yes. The owner establishes functional standards, spatial requirements, and finish expectations during early programming meetings. However, because the architect and contractor work under one contract, the owner must make firm design decisions early in the process to keep fast-tracked construction on schedule.
Public sector and municipal projects often mandate Design-Bid-Build by law to ensure taxpayer funds are awarded through a transparent, public lump-sum bidding process. This structure requires 100 percent complete plans to allow fair head-to-head price comparisons among general contractors.
In Design-Bid-Build, if a contractor encounters plan errors or omissions in the architectural drawings, they submit a change order to the owner for additional money and time. In Design-Build, because the contractor and architect are part of the same team, internal plan gaps are absorbed by the Design-Builder without additional cost to the owner.
A Guaranteed Maximum Price is a contract threshold set by the Design-Builder during design development. It caps the maximum financial commitment required from the owner for the defined project scope. Any cost overruns above the GMP are absorbed by the Design-Builder, provided the owner does not expand the project scope.
Design-Build eliminates design error risk and constructability conflict liability for the owner. However, the owner remains responsible for risks related to scope changes, unforeseen subterranean site conditions, municipal zoning delays, and force majeure events.
Yes. Many owners retain an independent architectural consultant or owner's representative to help write bridging documents, establish design standards, and review the Design-Builder's work. This allows the owner to maintain an independent technical advisor while keeping single-source contractor accountability.
Choose Design-Bid-Build if your project mandates strict public bidding laws, requires complete architectural plans before committing capital, or demands complete direct control over every architectural detail. Choose Design-Build if your priority is fast execution, single-point accountability, early cost certainty, and a collaborative team environment.
