Services & Solutions
As a Construction Manager, JLN provides the full suite of construction services to manage, construct, and deliver projects on time and with a minimum of headaches. With us, the key concept throughout the construction phase is control—control of schedule, cost, safety, security, quality, and close-out. Experience has taught us that when control and oversight are maintained, we are better able to manage issues that may arise. Foresight, proactive thinking, and active coordination are all key elements in controlling these items and ensuring project success.
The end of construction is not the end of our relationship. We continue to serve our project owners in many ways to make sure every aspect of the project meets their full expectations, and so that our post construction services serve as the bridge to our next project.
Building Structures
With our experience and expertise in structural engineering, JLN is able to provide innovative solutions through a variety of delivery methods—design-bid-build, design-build, building information modeling (BIM), and fast-track design. Our engineering staff has the cumulative knowledge to address the nuances, challenges, and complexities of today’s state-of-the-art building designs.

Using 2D and 3D maps and models generated from these technologies, our teams are finding new and better ways to design, engineer, and manage our clients’ sites, infrastructure, and assets.
