Dear Ms. Oquendo,
Z&K Consultants, Inc. (Z&K) is pleased to submit this revised proposal to provide construction inspection and materials
testing services for the City’s 2025 Alley Rehabilitation Project. We appreciate the opportunity to support the City.
The project generally includes removal and reconstruction of alley pavement, utility adjustments, traffic control, striping,
stormwater BMP implementation, and associated improvements in accordance with the plans and specifications.
Z&K proposes to provide experienced construction inspection staff for the anticipated 90 working-day construction
duration, with construction anticipated to begin in late March 2026. Our inspection services will be tailored to support the
City throughout all phases of construction and will include, but not be limited to:
•Construction inspection services during active work
operations
•Verification of compliance with approved plans,
specifications, and City standards
•Oversight of demolition, grading, PCC placement, and
utility adjustments

monitoring
•Stormwater and water quality BMP compliance
oversight
•Coordination with City staff, contractors, utility
companies, and affected stakeholders
•Daily inspection reports with photo documentation and
detailed field records

and businesses impacted by construction
Z&K will also provide materials testing and laboratory services through Converse Consultants. Converse will perform as-
needed field and laboratory testing services, including in-place density and moisture testing, asphalt and concrete testing,
and laboratory analysis to support construction quality assurance. Their services will be coordinated with the Contractor’s
schedule to ensure timely testing, reporting, and compliance with project specifications. Materials testing services will be
provided at competitive rates, offering a cost-effective solution for the City.

services for alley, street, and pavement rehabilitation projects throughout Southern California. Our team is well-versed in
managing construction activities in constrained urban environments while maintaining public access, safety, and clear

assumptions or scope as the project advances. Hourly rates are per the City’s approved on-call agreement and include
