and PS&E phases of the design process. This

includes

– Completing Section 6 of the SWDR

– Developing a phase appropriate BMP strategy

– Estimating costs for BMPs

– Preparing Final PS&E package

What is a Construction Site BMP Strategy?

What is a Construction Site BMP Strategy?

• It is a discussion of the selected Construction Site BMPs in a short narrative

• The level of detail will be different during the following phases:

− Project Initiation Document (PID)− Project Approval/Environmental Document

(PA/ED)− Plans, Specifications & Estimates (PS&E)

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.

Indicate the method of BMP quantity and cost estimates used in the narrative, and reference the

storm water BMP cost summary. Include it as a supplemental attachment.

PID PhasePID PhaseAs 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.

How Do You Develop the

at the PA/ED Phase?

How Do You Develop the Construction Site BMP

Strategy at the PA/ED 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 types to be implemented.

• What is an acceptable strategy at PA/ED?

At the PA/ED phase the strategy should become better detailed than in the PID phase, describing types of BMPs typically used on projects with a similar scope and range of construction activities.

18




How Do You Deal with Complex Projects at the

PA/ED Phase?

How Do You Deal with Complex Projects at the

PA/ED Phase?• While not technically required, use the

Construction Site BMP Consideration Form to aid in the selection of BMPs.

• Use the appropriate parts of Checklist CS-1, as instructed by the form.

• Develop a BMP strategy (types) from Checklist CS-1, Parts 1 – 6.

See Reference Material Tab Page 1

Construction Site BMP Strategy PS&E Phase

The Construction Site BMP strategy for this project shall consist of the following for soil stabilization and sediment control. Perimeter Controls shall consist of silt fence placed at the toe of all embankment slopes and gravel bag berms shall be placed along the construction pad above Smith Creek. Contour grading of slopes shall include surface roughening by walking the slopes with tracked equipment. Immediately thereafter, slope interruption devices such as fiber rolls shall be installed and soil stabilizer shall be hydraulically applied. Whenever possible, early implementation of permanent erosion control seeding or landscape planting shall be performed
