Still have questions about your project?
No two projects are exactly alike. Reach out to our team with your goals, property information, or project plans, and we'll help you determine the best path forward with practical engineering and construction guidance.
01 What types of projects does ENGCO work on?
We work on a wide range of land development, civil engineering, and construction projects for commercial, municipal, and industrial clients. Our team supports projects of all sizes, from individual site improvements to large-scale developments. We tailor every solution to meet your project's unique goals, timeline, and budget.
02 What should I have ready before requesting a quote?
The more information you can share, the better we can evaluate your project. Property details, surveys, site plans, drawings, and any permitting information help our team understand your needs. If you do not have everything prepared yet, we can still discuss your project and help determine the next steps. View our project process for more insights.
03Do you handle both engineering and construction?
Yes. ENGCO's land development model connects planning, civil engineering, and horizontal construction under one accountable team. That means the people shaping the plan and preparing the drawings stay connected to the project managers and crews responsible for building the site.
04 Why choose ENGCO instead of hiring separate engineering and construction companies?
Working with one team helps simplify your project from beginning to end. Because our engineers and construction professionals work together, we can improve coordination, reduce miscommunication, and deliver solutions that are practical to build. Our goal is to provide a smoother experience while helping you save time throughout the project
05 Can ENGCO manage my project from design through construction?
Yes. We provide both engineering and construction services, allowing us to guide your project from the initial concept through final completion. Our integrated approach helps improve communication, reduce delays, and keep every phase moving efficiently.
06 Do I have to hire ENGCO for every service?
No. We can support a single phase, such as engineering, septic design, or site work, or carry your project through every phase. Our team will recommend the combination that fits your scope and budget.
07 What is design-build, and is it right for my project?
Design-build means one team is responsible for both the design and the construction. Most of the projects in our portfolio were delivered this way, which cuts handoffs, speeds decisions, and keeps accountability in one place.
08 CDo you self-perform work or subcontract it?
Our own crews and equipment handle core scopes like concrete, framing, site work, site utilities, and base preparation. Specialty trades such as electrical, plumbing, HVAC, and roofing are handled by trusted subcontractors under ENGCO’s construction management.
09 Do you work on residential projects too?
Yes. Commercial, industrial, and municipal work makes up most of what we do, but we also design and build custom homes, additions, and residential subdivisions. One example is a 5,200 sq ft custom residence in Tomball, built from site development through pool and septic installation.
10 Can ENGCO manage my project from design through construction?
Yes. We provide both engineering and construction services, allowing us to guide your project from the initial concept through final completion. Our integrated approach helps improve communication, reduce delays, and keep every phase moving efficiently.
