Check with the COZEEP coordinator to determine location of the nearest CHP office that will be supporting your project. Reviewing the needs and control of all road users is an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents through a work zone. Temporary pavement markers will not adhere to a cold in-place recycling surface. of the lane closure unless the end of work area is 48" x 24" as appropriate, shall be placed at the end A G20-2 "END ROAD WORK" sign, with minimum size of the locations indicated for lane closure during Each flag shall be at least 16" x 16" in size with at least two flags for daytime closure. Before making a decision to approve a change order that would result in a prolonged ramp closure, weigh the results of the study with factors, such as construction costs, travel costs, delay, and safety. Verify the contractor removes or covers any construction area signs that duplicate or contradict the signs for a project within 250 feet of another project. Confirm the contractor uses the long-term temporary pavement marker for 180 days or less and the short-term temporary pavement marker for 14 days or less. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. The CHP sorts and subtotals the COZEEP service summary by project, including cost information. For public safety, when flaggers are not shown on the plans or specified and when ordered by the engineer, providing flaggers is change order work for which Caltrans pays 100 percent. During the preconstruction conference, discuss: https://dot.ca.gov/programs/construction/forms.
