Winspear Construction has worked with many different architecture firms covering a diverse portfolio of projects. This contract delivery method is when the Owner hires a single entity to provide the design and construction services for a project. As the design-builder, Winspear Construction provides complete management through all phases of the project which reduces the burden on the Owner by minimizing unknowns, cost increases, and schedule delays.


This is the most typical contract delivery method. The General Contractor is responsible for managing the construction of projects that are designed by outside architects. Winspear Construction would manage the onsite construction building process, subcontractors, schedule, safety, cost, & the overall completion of the project.


This service is used when an Owner uses a consultant to manage the time, quality, and budget for a project. In this role, Winspear Construction would represent the Owner for the entirety of the project.


Winspear Construction maintains an experienced crew of Foreman, Operators, & Laborers. We are capable of self-performing site clearing and grubbing, site concrete preparation and placement, landscaping sub-grade preparation, curb preparation and placement, and sidewalk preparation and placement.


Our crews have safely and successfully demolished a variety of structures, buildings, and site elements on multiple projects. Demolition requires proper planning and sequencing to ensure safe deconstruction practices are followed. We are environmentally sensitive and recycle as much deconstructed material as possible.


Winspear Construction specializes in all facets of excavation. Such items include building mass excavation and haul off, footing excavation and preparation, backfill, compaction, and grading. By owning the required equipment to perform these activities it allows us to be competitive and in return save money for our clients.


We have installed all types of utilities required for a functional building. This includes piping for gas, geo-thermal, water, sewer, electrical trench, telecom trench, fire, & storm water. Utility construction is an added value to our site prep and excavation services.


Our crews are certified and trained to install a variety of waterproofing systems, namely the W.R. Meadows. We also have the ability to inject a Hydro Grout Material into concrete foundations and walls to stop water from continually entering a structure.  We maintain the proper trainings to ensure critical quality requirements are met and all warranty obligations are adhered to.
