Enhanced inspection program - Land use

1

Applicant responsibilities

The applicant is responsible for

• the completion of the road and drainage infrastructure as depicted on the approved engineering plans.
• the day-to-day quality assurance and documentation necessary during construction.
• ensuring that the work the contractors and subcontractors perform is consistent with the approved plans, adopted standards, and any other applicable regulation or condition.

2

Applicant installation and maintenance requirements

The applicant is required to install all necessary erosion and sedimentation control measures and maintain them throughout the construction period to ensure soil and other debris are not tracked onto roadways and sediment laden water does not enter natural or existing drainage systems on or off the site.

3

Staffing requirements

The applicant will employ staff in the following roles (when determined by King County, the same person may serve all or some of the required roles).

• Construction Manager: The permit applicant’s representative who administers the construction contract for the applicant. The Construction Manager shall assume the duties of the Contracting Agency as defined by the WSDOT Standard Specifications.
• Project Engineer: The Construction Manager’s representative who directly supervises the contractor and quality assurance engineer, and has funding control over the contract. The Resident/Project Engineer is the initial point of contact between the contractor and DDES.
• Quality Assurance Engineer: The Project Engineer’s representative who inspects the contractor’s performance in detail, provides on-site sampling and testing, and obtains approval of material sources and material certifications.
• Certified Erosion and Sedimentation Control Lead (CESCL): A person who meets the requirements of BMP C160 (PDF*, 165KB): Certified Erosion and Sediment Control Lead (external link), Washington State Department of Ecology 2005 Stormwater Management Manual (external link) for Western Washington.
• Professional Engineer:  A professional civil engineer registered and licensed to practice in the State of Washington is required when indicated by the King County Road Design and Construction Standards and/or the Surface Water Design Manual.

Documentation and inspection verification

The applicant must voluntarily agree to

• remove the activity from the DDES Financial Project Management program (for example, a fee estimate will not be provided).  Refer to the DDES financial policies protocol for detailed information.
• comply with the requirements of chapter 9 of the current King County Road Design and Construction Standards (the 2007 KCRDCS at present), even if the project had been vested under an older standard.
• obtain a written verification from the DDES inspector prior to moving on to the next stage of construction. See Appendix A (PDF*, 33KB) for details.

Materials testing verification and documentation

The applicant shall document that all materials used on the construction site meet minimum plan requirements and standard specifications. All testing must be reviewed and approved by the applicant’s Quality Assurance Engineer and be provided to the DDES inspector for verification prior to moving on to the next phase. For example, trench and subgrade density tests shall be reviewed and approved by the Quality Assurance Engineer and verified by the DDES inspector prior to proof rolling and placing road surfacing materials.

Critical inspection tasks

Inspection phases that have been verified by the DDES inspector shall not be construed as a final construction approval for that phase or item (see King County Road Standards Chapter 9, section 9.02 Inspection, as well as Appendix A, PDF*, 33KB). The responsibility is upon the applicant and the applicant is obliged to ensure that the entire project is consistent with the approved plans and changes, standards, specifications and conditions of permit issuance or approval at the time of Final Construction Approval.
