Construction Expeditors completed a full side sewer replacement for a recently renovated apartment building in Seattle, originally constructed in 1956. The scope involved replacing the building’s existing sewer connection from the structure to the municipal sewer main located in the street.

This type of utility work is highly regulated and requires precise coordination within the public right-of-way, as well as compliance with City of Seattle and Seattle Department of Transportation requirements. We managed the project end-to-end as the general contractor, including permitting, agency coordination, excavation, installation, and restoration.

Regulatory Coordination and Execution

Side sewer replacement work in Seattle requires specialized licensing for both the general contractor and subcontractors, along with ongoing inspection and approval from city agencies. This project required coordination with inspectors and utility authorities to ensure compliance.

All public right-of-way work was performed under approved traffic control plans, with scheduled closures and staged access to minimize disruption to surrounding properties and pedestrian traffic.

Delivery and Project Control

We completed the work on schedule and on budget, with proactive coordination throughout construction. Sequencing of excavation, utility installation, inspections, and restoration was carefully managed to avoid delays and ensure compliance with permit conditions.

Communication was maintained from planning through completion to keep the client informed of progress, inspections, and street restoration timing.

What This Means for Property Owners and Investors

Successful completion of utility work protects long-term asset performance, reduces the risk of future utility failure, and ensures compliance with municipal standards in dense urban settings.

Managing multifamily assets, utility, and infrastructure work requires a skilled general contractor with the licensing and experience to complete complex work in regulated urban environments. Sewer system and other utility upgrades in older buildings require careful coordination with city agencies, strict adherence to permitting requirements, and disciplined execution in active public rights-of-way.
