Background • Facility Wide Safety Assessment, Project No. SP-145-1 completed in December 2014. Comprehensive safety assessment of all OCSD facilities to : • Enhance worker safety • Ensure compliance with safety codes • Provide reliable and efficient facilities for O&M • Identified ^' 1700 deficiencies, ranked by priority • Corrective measures developed based on ANSI risk assessment methodology Plant - Cen Gen Roof Access Fall r rop Ladder exposed to stairwell.

• Construction cost • Design effort _ l Plant 1 - Package 'F' Considerations for Construction Packaging • Speed • Lower priority should not delay higher priority • Lower complexity can be designed faster than high complexity • Related Work • Similar items may be grouped together • Smaller contracts = higher non-construction costs • "Piece-mealing" will not be used to circumvent procurement requirements Project J-126 Delivery Title Subject Location A Phase 1 Field Investigation 1 Package J-126A Hot Surfaces Insulation and Machine Guarding P1, P2 2 Package J-126B Emergency Lights, Exit Signs, Electrical Maintenance PS 3 Package J-126C HVAC Improvements(NFPA 820) P1 T 4 Package J-126D Hatch Modifications P1 a 5 Package J-126E Roof Fall Protection and Skylights P1, P2 6 Package J-126F Ladder and Walkway Hazards P1, P2 7 Package J-126G Ladder Modifications PS 8 Package J-126H Various Bay Bridge PS, Slater PS B Phase 2 Field Investigation 9 Package J-1261 Exit Signs and Electrical Disconnects P1, P2 10 Package J-126J Stairs, Hatches,Walkway Hazards P1, P2, PS `o a 11 Package J-126K Ladders, Guardrails, Roof Fall Protection P1, P2 E 12 Package J-126L Various PS 13 Package J-126M Machine Guarding and Walkway Hazards P1, P2 14 Package J-126N Electrical Upgrades(NFPA 820) P1, P2 C Phase 3 Field Investigation 15 Package J-1260 Emergency Lights and Gas Detection P1, P2 16 Package J-126P Ladders and Hatches Sari, College Ave, Lido and Main Street PS a 0 17 Package J-126Q Roof Fall Protection P1, P2 J 18 Package J-126R Machine Guarding P1, P2 Consultant Selection • RFP Issued (April 2016) • Two Proposals Received (Arcadis, Hazen & Sawyer) • Arcadis selected as best qualified • PDSA Awarded to Arcadis, US, Inc (July 2016) Consultant Scope and Budget • Task 1 Program Services • Project Management • Implementation Plan (Construction Packaging) • Chartering Construction Packages • Cost Estimating and Scheduling • Safety Review • Workshops and Meetings Consultant and B • Task 2 Construction Package Execution • Original scope of work based on deficiency types with allocations • Multiple Construction Packages • Large number of unique deficiencies • Difficult to determine level of effort • Design at 20% of original construction estimate $1,.0001000 • Individual package fees negotiated after detailed field investigations define solutions Construction Costs • SP-145- 1 Construction Cost Estimate = $5 .4 million • Reasonable possibility that the construction cost could double • SP-145-1 unit prices significantly underestimated 2017-2018 installed costs • 40 additional deficiencies have been added to the program since the design agreement was awarded • Re-roofing of four P1 digesters to correct slippery surface conditions (P1-100) ($500,000 - $750,000) Consultant and B • Need for Additional Task 2 Funding • Increase in Construction Cost • Original fee estimate did not include construction phase services Original Basis Current Estimates Increase Consultants Costs Program Services (Task 1) $ 576,162 (11%) $ 576,162 (6%) $0 Engineering Services (Task 2) $ 963,838 (18%) $ 2,463,838 (25%) $1,500,000 Total Consultants Costs $1,540,000 (29%) $ 3,040,000 (31%) $1,500,000 Construction Cost Estimate $5,400,000 $10,000,000 $4,600,000 Project J-126 Delivery Status Title Subject Status A Phase 1 Field Investigation Negotiated 1 Package J-126A Hot Surfaces Insulation and Machine Guarding Negotiated 2 Package J-126B Emergency Lights, Exit Signs, Electrical Maintenance Negotiated 3 Package J-126C HVAC Improvements (NFPA 820) Pending Additional Funding T 4 Package J-126D Hatch Modifications Pending Additional Funding 5 Package J-126E Roof Fall Protection and Skylights Negotiated 6 Package J-126F Ladder and Walkway Hazards Negotiated 7 Package J-126G Ladder Modifications Negotiated 8 Package J-126H Various Negotiated B Phase 2 Field Investigation Negotiated 9 Package J-1261 Exit Signs and Electrical Disconnects Pending Additional Funding 10 Package J-126J Stairs, Hatches,Walkway Hazards Pending Additional Funding 0 a 11 Package J-126K Ladders, Guardrails, Roof Fall Protection Pending Additional Funding E 2 12 Package J-126L Various Pending Additional Funding a 13 Package J-126M Machine Guarding and Walkway Hazards Pending Additional Funding 14 Package J-126N Electrical Upgrades(NFPA 820) Pending Additional Funding C Phase 3 Field Investigation Pending Additional Funding 15 Package J-1260 Emergency Lights and Gas Detection Pending Additional Funding _T 16 Package J-126P Ladders and Hatches Pending Additional Funding a 0 17 Package J-126Q Roof Fall Protection Pending Additional Funding J 18 Package J-126R Machine Guarding Pending Additional Funding Recommendations • Approve a budget increase of $1,500,000 for Safety Improvements Program, Project No. J-126 • Approve Amendment No. 1 to the Professional Design Services Agreement with Arcadis, US, Inc., for Safety Improvement Program, Project No. J-126, for an additional amount of $ 1,500,000
