General Contracting

We offer comprehensive general construction services and guidance to each client. With a forward-thinking approach that combines real teamwork and modern technology to give you an organized and timely delivery.

Design Build

Projects often begin as an idea on a piece of paper. At Hennessy Construction, we're professionals at taking those ideas and working with you to turn them into a reality. We handle and manage the entire project from start to finish, provide competitive pricing, and care for value engineering. 

Value Engineering

We provide our clients with current pricing and product schedules. Evaluate materials and methods to ensure that our client's project not only uses the right product for the desired application but that any products we recommend are easily obtainable and deliverable.

Programming and Space Planning

Our vast experience both in planning and construction enables us to work with the client from the onset, turning their needs into spaces that provide better comfort, functionality and aesthetic.
The Hennessy Construction team includes experienced estimators and project managers who will review your drawings and generate a carefully considered estimate you can trust. Our proven process and comprehensive database with over a decade of historical data allow us to produce better, more accurate cost projections that significantly reduce the likelihood of change orders during the construction phase.

Cost Estimation

Estimating is one of the most essential steps when planning a construction project. We deliver expert construction cost estimating services that enhance budgeting accuracy and reliability. Our team includes experienced estimators and project managers who will review your drawings or models and generate carefully considered estimates you can trust. As a result, our clients have fewer concerns about overruns or unanticipated scheduling delays. Our process allows clients to see numerous potential cost saving options, giving them the ability to make educated decisions.

Custom Millwork

Whether you are updating your current space or building a new property, custom millwork is something to consider. This architectural woodwork is custom-built to your vision, increasing the value of your space while also creating unique, beautiful and eye-grabbing statement pieces for any building. Our team will work closely with you to ensure one-of-a-kind woodwork that is built exclusively for your taste, style, and requirements, with massive customization options, such as wood species, grain patterns and much more.

Long Term Facility

The average building maintenance team takes care of a lot of the work directly, but there are times when clients need to bring in vendors. For example, in many areas, only licensed, specialized technicians can work on fire suppression, elevators, mechanical systems etc. We aim to maintain our relationships with our clients even after finalizing a project by offering services that stretch beyond full scale build-outs. Whether it’s hanging a TV or adding power to a desired location. Hennessy Construction will be able to assist you.

Data Center

The decommissioning process requires comprehensive planning and management. These projects often involve several vendors, strict timelines, and many variables. Services include, and are not limited to: asset list reconciliation; decommissioning, redeployment, or remarketing of IT hardware and infrastructure.
