How Do You Develop the Construction Site BMP Strategy at the PID Phase? How Do You Develop the Construction Site BMP Strategy at the PID Phase? Use Section 2 (“Selecting/Implementing Construction Site BMPs”) of the Construction Site BMPs Manual to identify BMPs for the project. The level of detail should include BMP categories to be implemented. What is an acceptable strategy at the PID phase? At the PID phase, the strategy should be very general. Give a list of BMP categories to be implemented. 10 Completing SWDR - Section 6 BMP Strategy Development Estimating Construction Site BMPs in PS&E Phase

Include it as a supplemental attachment. PID Phase As outlined in appendix F of the Project Planning and Design Guide, the percent of total cost method was used for estimating the cost of Construction Site BMPs. At this time no Construction Site BMPs have been designated as separate bid line items. This project will require a storm water pollution prevention plan (SWPPP). Construction Site BMPs will be incorporated into the project. The costs to prepare the SWPPP and implement the Construction Site BMP work are estimated at 2% of the entire construction cost. See the storm water BMP cost summary (supplemental attachments) for specifics concerning costs. 13 Completing SWDR - Section 6 BMP Strategy Development Estimating Construction Site BMPs in PS&E Phase

San Mateo 1, Culvert Replacement Project Questions 59

Well, I have a few more questions... Can a practice identified in , Construction Site Management, also be identified as a separate bid line item? 60 At a minimum, how must Construction Site BMPs be identified in the contract documents? Is the Water Pollution Control Cost Break-Down still a part of the contract documents?
