DREDGING YOUR DOCKS 2014 Supported by USCOE Galveston District U. S. Coast Guard Port of Houston Houston Pilots Lone Star Harbor Safety Com.

Dredging Cost Presentation Dredging private dock terminals Focus on hydraulic dredging Total project cost to owners Industry standards & requirements

Dredging Cost Project Specific Disposal Surveys Permitting Environmental External Cost Impacts

Identifying the scope of work: Project location Cubic yards of material Dredging template Over-dredge requirements Type of material

Choosing a Dredge: Dredge Size Project Specific requirements Type of material Pumping capacity Location Schedule

Selecting A DMPA Federal DMPA Private DMPA Uplands Beneficial Use

Dredge material placement area requirements (DMPA) DMPA location DMPA Specific requirements Pipeline route Discharge Point Crossings Ship Channel – Road Levee systems Capacity

Dredge Pipeline Cost Distance from Project to DMPA Floating, submerged, & land Pipeline route Discharge Point Crossings - Ship Channel – Road

Dredging Cost Breakdown Mobilization / Demobilization Pipeline Cost Cubic Yard Unknowns anomalies, debris, & delays Disposal Cost based on gross yardage management fees sediment samples

DISPOSAL COST DMPA COST Disposal Fees Deposit & Contract Signing Payment of Gross CY dredged Sediments Sampling Cost Management Fees Application – Consulting

DISPOSAL COSTS (per cu/yd.)

FUEL COSTS

STRUCTURAL STEEL COSTS (per ton.)

Project “A”

Project “B”

PROJECT “A” & “ B” Project “A” 115,000 cy x 8 days = 14,375 cy per dredging day Project “B” 13,000 cy x 5 days = 2,600 CY per dredging day

PROJECT “A” & “B” Overview Same dredge spread Pipeline & DMPA Similar dredge template Projects shared the mobilization cost Cost per CY is 5 times for Project “B” than “A”

HYDROGRAPHIC SURVEY Pre-Dredge Survey by Contractor Pre-dredge survey by Third Party Verify, Quantities, Tide Gauge, & intervals Verify survey datum and station #’s

Post dredge survey by Surveyor & Contractor Post-Dredge Survey review Pay DMPA & Contractor

Permit Requirements TCEQ Water Quality Certification USACE Permits Regulatory Real Estate NWP Permits DMPA Permits

EXTERNAL COST Environmental Impacts Economic Development Government Requirements USACE Regulatory USACE Real Estate EPA TCEQ Legal – Jones Act

DREDGING COST SUMARY Plan Dredging Activities Have Permits in Order Piggy Back off USACE Share Mobilization Cost with Neighbors Coordinate DMPA Contracts Early
