About this file
This is a Work Sequence and Constraints document for a construction project involving Clackamas County and the Oak Lodge Water District in Oregon. The document outlines general project requirements and phasing for work that includes site clearing, demolition, excavation, rough grading, installation of drainage and utility infrastructure, electrical work, pathways, flatwork, park features, planting, and right-of-way improvements. Key constraints require that traffic flow be maintained on Wilmot Street and Hull Avenue during construction, and adjacent residential areas must be protected from work-related equipment traffic except as specifically approved. The contractor must maintain overall coordination of work execution, obtain and incorporate schedules from all subcontractors and suppliers into a master progress schedule, and pre-locate existing utilities through exploratory excavation to minimize service interruptions.
Utility service interruptions are permitted only with written authorization from the engineer, and requests must be submitted at least five business days in advance. The engineer will evaluate interruption requests based on utility owner personnel availability and impact to customer service, with the contractor responsible for minimizing interruption duration through advance planning and procurement. All special and material inspections must comply with the latest edition of the International Building Code, requirements of Oak Lodge Water District and Clackamas County, and state of Oregon standards. The document specifies a general work sequence beginning with site clearing and demolition, followed by grading and berming, underground utility installation, electrical work, flatwork and pathways, park features and planting, and finally right-of-way improvements.
