Teamwork. Early Lehigh involvement. Collaboration. These characterize the Lehigh approach to the design-build process from inception to successful completion.

Design-Build Quality

Owners are assured that quality standards will be maintained through Lehigh’s careful selection and pre-qualification of subcontractors and vendors using all delivery systems.

Design-Build consultants carry out inspection and review of quality, specification and code adherence of the work.

Strict Schedule

Design-Build options mean that a close working relationship can compress the schedule via early review and identification of constructability issues, material and equipment availability,and construction trends.

Design Build Budget Options

The budget for design-build projects is developed early and reviewed continuously throughout the design and construction process with your Project Manager.

The competitive bid and vetting process is preserved and strengthened through pre-qualification of all Lehigh subcontractors and suppliers.

While there are several common construction project delivery systems commonly used, Design-Build is a preferred option for Lehigh Construction Group.

Design-Build Contractors (DB)

The Design-Build model is preferred by Lehigh as it offers owners a single point of contact overseeing a proven team of design and Lehigh construction professionals under one contract to deliver the D-B construction project from start to finish.

Since the Lehigh team is responsible for both design and construction, pricing changes can be kept to a minimized and are usually limited to instances where unknown conditions exist, or an owner requests additional adjustments beyond the original project scope.

Design-Build often offers faster delivery and is often the most cost effective option for a team that has worked together over decades with hundreds of projects delivered on time and within budget.  Owners establish a firm maximum price for their project to help maintain significant cost control.

Design-Build is ideal for construction projects where owners have clearly established requirements prior to design.

Design-Bid-Build (DBB)

Lehigh is also able to work with this more historical system of delivering building projects that delineates between the design and construction process. 

The criteria for contractor selection in design-bid-build (DBB) projects is usually the lowest construction price. To begin the DBB process, an architect is hired by the owner to create design documents (drawings and technical specifications) for a project, who will usually also develop a project cost estimate and schedule.

Once design documents are completed, a Request for Bids is created and released to contractors. Contractors then evaluate the project documents and provide a price for the work. The architect answers bidder questions and assists the owner in evaluating the bids. Once a bid is selected, the owner establishes a contract with the chosen contractor, and work begins.

The DBB method is the most familiar and traditional, and while providing the ability to deliver low-cost projects, it isolates contractors from the design process, creating a potential for project cost increases due to conflicts between the design documents and actual construction project in the field.  Selecting a low bidder can result in a decrease in the quality of the finished product as contractors maximize profit on the job using the lowest cost contractors.

This project delivery method is less common for Lehigh, and involves two contracts for the owner.  The Architect and Contractor both have contracts, and the Construction Manager is selected based on both qualification and fees.  This model normally involves open book costing fpr subcontractors during the entire procurement process.

Construction Management at Risk (CM/GC)

Lehigh is also able to deliver construction projects using the CM at-Risk method to deliver the job within a defined schedule and price.  Lehigh provides construction input to the owner during the design phase, and becomes the general contractor during the construction phase for either a fixed lump sum, or a guaranteed maximum price (GMP).

 In this model, the owner is responsible for design details, and is liable for “gaps” that exist between the plans and specifications, and the owner’s requirements.

While Lehigh can also build projects using all other models, the Design Build project delivery system has proven very beneficial for our customers, and D-B remains the preferred Lehigh construction method.
