Pre-Construction Services

A successful project is built on the foundation of diligent planning.  At a project's inception, our pre-construction team begins working with owners to ensure that the job is functionally and financially viable. In addition to estimating, the pre-construction team facilitates design decisions, evaluations, value engineering, scheduling, constructability reviews, and more. Design costs, permitting, land acquisition, and life-cycle costs may also be evaluated.

As design/builders, O'Brien is able to minimize risks for project owners, reduce overall costs, and accelerate the delivery schedule by overlapping the design phase and construction phase of a project. By acting as the single point of responsibility for the project, we are able to bring all members of a project team together early in the process to identify and address issues of cost, schedule and constructability. This collaborative approach allows us to harness the strengths of our innovative team and apply value engineering at the project's inception. With over 50 years of experience, O'Brien partners with industry-leading architects, engineers, and specialty trade contractors who propose best-value solutions for various construction elements before the design is complete, thereby dramatically increasing efficiency and reducing change orders, cost growth and schedule delays.

Energy Solutions

Energy is one of the largest operating costs for building owners and operators. Inefficient buildings drive up operating costs by losing energy through under-insulated walls, roofs and windows.  When building systems such as HVAC, Electrical and Plumbing are performing at less than optimum efficiency, they add unnecessary expenses to your operation.  We show you exactly how these structures and systems can be economically retrofitted or replaced to provide immediate cost savings.  We begin by conducting a comprehensive energy study for your business to identify areas of inefficiency and then provide specific upgrade options. Through energy audits and a clear cost/benefit analysis, we will help you clearly identify the potential savings to your bottom line.

LEAN Construction

LEAN Construction delivers a project with minimum waste of materials, time, and effort in order to generate the maximum possible amount of value. A key component to this strategy is pull scheduling, or reverse-phase scheduling, which requires collaboration of all project participants at the early stages of the endeavor and continuing throughout all phases of construction. Based on a master schedule with key milestones, pull scheduling begins with a scheduling workshop during which all stakeholders develop a specific plan for each phase of construction. The object is to keep the team working on well-defined deliverables at a reliable and predictable pace in order to eliminate re-work and waiting. By applying LEAN construction practices to every job we do, O'Brien has seen a significant increase in efficiency and greater job satisfaction for our skilled trades.
