How We Work
Preconstruction
We assess the space, price the work and flag schedule risks before design is final.
Design-build MEP
Through our trusted engineering partners, we provide coordinated mechanical, electrical, plumbing, and life-safety design services, helping streamline delivery, reduce coordination gaps, and accelerate project schedules.
Value engineering and permitting:
We find cost and schedule savings and manage permit expediting.
Construction and closeout
We phase work around your operations and coordinate with your furniture, AV and data vendors so you move in on schedule.
"The office is even more beautiful and comfortable than the pictures imply."

Frequently Asked Questions
How long does an office build-out take?
Most office construction projects are completed within 8 to 24 weeks after permit issuance, depending on the size of the space, project complexity, and material lead times. Early contractor involvement can significantly improve schedule certainty and reduce delays.
What is a tenant improvement?
Construction that customizes a leased commercial space for a tenant, often funded in part by a TI allowance in the lease.
Can you renovate our office while we keep working?
Yes. We phase the work and schedule disruptive tasks after hours and on weekends, as we did for Bailard.
When should we bring a contractor in?
Ideally during site selection or early design. Involving a contractor early helps establish realistic budgets, identify schedule risks, and negotiate tenant improvement allowances with confidence.
Planning an Office Move, Expansion or Renovation?
Whether you're relocating, modernizing an existing office, or building out a new space, Rylko Builders can help you evaluate costs, schedule requirements, and project risks before construction begins.
