Turnkey design-build solutions.

A construction project — no matter the type or size — has many moving parts, managing relationships with multiple parties, including architects, consultants, contractors, subcontractors, and vendors. If you’re looking to simplify and streamline your renewable, development, industrial, and oil and gas project, you can trust RETTEW to handle all aspects for you.

RETTEW has decades of experience in private and public construction management. We’ll take time to get to know your vision and goals, and we’ll consider and address any complications that could potentially arise — this holistic approach results in fewer change orders and adherence to schedule and budget. In fact, our foresight and attention to detail has saved our client headaches, streamlined workflows, and kept communication strong.

Our design-build team observes and monitors your project every step of the way to ensure it’s on spec, up to code, and operations are adhering to safety standards. We’re well known industry-wide for our commitment to safety on every jobsite and with every procedure, as well as promising quality results.

Your single point-of-contact.

At RETTEW, we can bring the design and build processes together, which, for you, means time and cost savings. Our comprehensive design-build and engineering, procurement, and construction services allow you to have a single point-of-contact while our team keeps you informed and involved. We’ll assemble a qualified team, only using vetted, reliable, and respected partners. RETTEW will serve as the main detail manager — we’ll facilitate the communication, scheduling, invoicing, and other project management duties, ensuring our collaborative team is working efficiently and smoothly, on-time and on-budget.

Your energy goals come to life.

RETTEW’s Design-Build group works in tandem with our Energy and Environmental Engineering experts on solar, biogas, organic waste, produced water, and battery energy storage system design and construction. We’ve built a name for ourselves in the renewable energies market, working with both public and private entities to secure funding, create optimal agreements for operations and cost savings, and of course, produce energy resulting in reduced costs and long-term gains. Clients find the process smooth and simple when working with RETTEW.
