Perteet will attend <br />one (1) comment review meeting with the City staff and provide the City with written responses <br />to the City’s comments. Responses will be provided on the commented documents provided by <br />the City. The plans will be prepared to a level of competency presently maintained by practicing <br />professionals in the field of transportation engineering in the Puget Sound Region. <br /> <br />The 30% design effort will include the development of the preliminary roadway design; <br />including the horizontal and vertical alignment, curb, curb and gutter, sidewalk layout, <br />preliminary wall profiles (CAD format provided to David Evans and Associates, Inc. for plan <br />sheet creation), preliminary driveway profiles, paving sections, water main layout, drainage <br />layout, channelization, site preparation, erosion control, and preliminary 30% opinion of costs. <br /> <br />30% Plans <br />It is anticipated that the 30% civil, roadway, water, and drainage plans will consist of the <br />following sheets (19 sheets): <br />x Survey Control and Construction Alignment Plan (1 sheet) <br />x Construction Access Plan (3 sheets) <br />x Typical Sections (2 sheets) <br />x Paving Plan and Profile (4 sheets) <br />x Drainage Plan and Profile (4 sheets) <br />x Water Main Plan (2 sheets) <br />x Driveway Profiles (1 sheet) <br />x Channelization and Signing Plan (2 sheets) <br /> <br />30% Opinion of Cost <br />Perteet will calculate 30% design level quantities and prepare an opinion of construction costs <br />based upon the 30% construction plans and current unit bid prices. A contingency will be <br />included to accommodate additional construction costs not yet specifically identified. <br /> <br />Preliminary Design and P&E QA/QC of Deliverables <br />An internal Perteet quality assurance/quality control review of deliverables will be conducted, as <br />well as confirmation that comments received have been addressed. A record of comments <br />received will be maintained. Response to each comment received will be tracked to confirm that <br />they have been addressed. <br /> <br />Assumptions: <br />x The City will finalize the general geometric layout of the proposed improvements <br />through the review of the 30% submittal. The layout shall not be substantially modified
