Federal-Ready Construction, Built to Endure

Sierra Line Construction is a mission-driven construction firm delivering civil, federal, commercial, and emergency projects across California with clarity, speed, and zero compromise.

ABOUT SIERRA

Civil Work. Moral Structure. Zero Compromise.

Sierra Line Construction delivers public and private infrastructure projects with purpose and precision. Founded by Serge Zhilko—a first-generation builder with grit, faith, and field-tested leadership—we exist to raise the standard of California construction.

From sidewalks and sewer systems to federal builds and emergency work, our crews show up, finish strong, and never disappear when it gets hard.

We serve clients who are done gambling on flaky crews—and ready for a contractor who takes the mission personally.

WHAT WE BUILD

Reliable Construction. Real Results.

Sierra Line Construction specializes in five categories of work—all built to spec, on schedule, and with the accountability high-stakes jobs demand.

HIGH-END LUXURY HOMES

We build private residences with the same rigor we bring to federal jobs. From concrete pads to luxury interiors, we construct custom homes for clients who expect clean craftsmanship, scheduling discipline, and a builder who treats the project like their own legacy.

Civil Infrastructure

Sidewalks, sewers, storm drains, roadways, grading, and underground utilities — we handle end-to-end scopes with crews trained in compliance, safety, and spec-perfect delivery. Whether you're managing a city upgrade or supporting a prime bid, our work is clean, accountable, and built to last.

Federal Projects

We support government-funded developments, infrastructure scopes, and public works projects that demand documentation, discipline, and zero rework. From multi-home builds to sub-utility tie-ins, we bring bonded crews and bulletproof process to every federal job site.

Commercial Construction

Interior and exterior improvements for retail, office, and institutional facilities. We deliver build-outs, ADA upgrades, code compliance scopes, and infrastructure retrofits — all with professional staging, after-hours scheduling, and zero disruption to your operation.

Emergency Service Work

When infrastructure fails or disaster strikes, Sierra steps in. We provide rapid-response repairs, site stabilization, barricades, board-ups, flood recovery, and urgent safety remediation to restore function — and protect public safety — fast.

Frequently Asked Questions

What types of projects does Sierra Line Construction specialize in?

We focus on five core areas: commercial construction, federal projects, civil infrastructure, emergency service work, and high-end custom homes. Each service is backed by licensed crews, bonded compliance, and an uncompromising commitment to doing things right.

Is Sierra Line Construction licensed and insured for federal and public work?

Yes. We are CSLB licensed, bonded, and fully insured. Our crews are OSHA-certified, ID-badged, and trained for both public and federal job sites.

Can you handle fast-turnaround or emergency response projects?

Absolutely. Our emergency service division is built for high-speed deployment — from securing damaged sites to accelerated infrastructure work where timelines are critical.

Do you work with general contractors and primes?

Yes. We often serve as a trusted subcontractor or scope lead for primes, GCs, and developers—especially when schedules are tight and reliability matters most.

What regions do you currently serve?

We operate across California, with active coverage in Sacramento, San Joaquin, Contra Costa, Alameda, the Central Valley, and the Inland Empire including San Bernardino and Riverside counties.

Do you offer residential construction services?

Yes, but selectively. We take on custom homes and private infrastructure projects on a case-by-case basis—based on alignment with our schedule, scope, and quality standards.
