Having an alternative delivery tool in the box for faster disaster recovery at the Town of Lyons

Transcription

1 JW Having an alternative delivery tool in the box for faster disaster recovery at the Town of Lyons Alternatively described as How we teamed through a hybrid design-build delivery approach to help the Town of Lyons restore critical infrastructure & get back to pre-flood planning and activities for the WWTP. May 2, Presented by: Town of Lyons, CO Jim Blankenship Filanc Construction Justin Whittaker CDPHE WQCD Mark Henderson Honeywell Gary Berngard Tetra Tech Mark Maxwell 1

2 JW Agenda/Topics 1. Introductions 2. Comparison of alternative delivery methods 3. Where Lyons was pre-flood with respect to WWTP improvement needs 4. The flood -- Town-wide impacts 5. The flood -- WWTP impacts 6. Long-term recovery 7. Closing comments 2

3 JW Introductions Justin Whittaker, Filanc Construction Jim Blankenship, Lyons Town Engineer Mark Henderson, CDPHE Water Quality Control Division Gary Berngard, Honeywell Mark Maxwell, Tetra Tech 3

4 JW Comparison of Alternative Delivery Methods General Comments on Swim Lanes 4

5 JW Comparison of Alternative Delivery Methods (cont.) Prior slide addressed differences from an owner risk perspective Time to market Design-build versus design-bid-build 33% faster Hybrid design-build in emergencies Invaluable & immeasurably faster 5

8 GB Where Lyons was pre-flood WRT WWTP improvements Pre-Flood 7

9 GB Pre-Flood Swim Lane for the WWTP (cont.) Critical improvement needs Age & reliability Odor Noise Lack of redundancy High energy use & other operating costs 8

10 GB Pre-Flood Swim Lane for the WWTP (cont.) 4-year process between Town & Honeywell to address critical WWTP issues Leading up to September 2013 (preflood) activities completed included -- Evaluation of alternatives Preliminary engineering report submitted to CDPHE State Revolving Fund loan application submitted DOLA Energy Impact grant applied for (cont.) 9

11 GB Pre-Flood Swim Lane for the WWTP (cont.) 10

12 GB Pre-Flood Swim Lane for the WWTP (cont.) Pre-flood activities completed (cont.) Value-based competitive proposal process to pre-qualified design-build teams completed Filanc Construction/Frachetti Engineering team selected as Honeywell s primary sub-contracted design-build team We left 4 PM on September 11 th in the rain expecting award to Filanc in a few weeks 10

23 Jim Emergency Recovery Search & recovery Major issues beyond search & rescue Evacuation order ALL utilities down, not even cell phone Challenges to assess & restore Limited resources to support small Town Benefit of known expertise & relationship from the Honeywell/Tetra Tech/Filanc-Frachetti design-build team 21

24 Jim Long Term Recovery Lots of issues General infrastructure Parks & recreation Housing Economic impacts (tax base) Etc. WWTP does not need to be part of this because planning, options, etc. completed prior to flood Flood supported decision to stay in current location 22

25 GB The Flood WWTP Impacts Emergency response -- Boots-on-the ground Peak event was 7 PM, September 12 th Team on-site Sunday, September 14 th -- as soon as the water was low enough to access the site Team attendance Jim Blankenship Sandy Banta, former Town Trustee Pre-flood performance contracting designbuild team Honeywell, Tetra Tech, Filanc, Frachetti Preliminary emergency plan (scope, pricing, etc.) compete Monday September 15 th 23

26 MM The Flood WWTP Impacts (cont.) Lost all equipment for influent screening and pumping, effluent disinfection equipment & building and plant outfall/discharge line to St. Vrain Creek. Primary treatment trains intact and not damaged or breached by flood waters the island withstood the flood. Identified emergency temporary repairs needed to restore plant to full operation -- $270K Fast track approval from WQCD for temporary permit with expectation that we would shortly thereafter begin pre-flood renovation project Pre-flood SRF loan approval received on October 8 th, with allowance to add other needed water and/or wastewater repairs resulting from the flood 24 24

27 MH The Flood WWTP Impacts (cont.) Emergency response shuffling the designbuild brain-trust Jim Blankenship Town Engineer Gary Berngard/Honeywell (Pro-bono) Wastewater recovery coordinator Mark Maxwell/Tetra Tech Schematic design Justin Whittaker/Filanc Cost-effective fasttrack constructability Mark Henderson/CDPHE WQCD Public health & environmental compliance Sean Dibble/AWWS Plant operator 25

28 MH The Flood WWTP Impacts (cont.) Emergency response CDPHE support & involvement Site visit following week Town, WQCD, FEMA, Army Corps of Engineers & plant operator Teaming to address administration, operations, design CDPHE Internal Coordination permits, compliance, engineering Engineering / Design onsite evaluation of proposed repairs and modifications Expedited issuing of design approval for construction 26

29 GB The Flood WWTP Impacts (cont.) Emergency response (cont.) Fair and reasonable pricing Open book from Filanc based on designbuild team field engineered 1-lines & lots of discussions Opinion of probable cost from Honeywell/ Tetra Tech to validate Filanc pricing & approach (cont.) 27

30 GB The Flood WWTP Impacts (cont.) Emergency response (cont.) Fast-tracking implementation WQCD review and approval process Construction -- with lots of daily on-site discussions Inspection & temporary operating permit Timing of repairs Emergency repairs funded by Colorado Intergovernmental Risk Sharing Agency (CIRSA) Moved forward before we had CIRSA approval Worked with FEMA as a fall-back 28

31 GB Long term recovery back in the pre-flood swim lane 29

32 GB Long term recovery (cont.) back in the pre-flood swim lane 30

33 GB Long term recovery (cont.) back in the pre-flood swim lane Long term performance guarantees from Honeywell Operating cost savings will pay for 40% of construction cost without ratepayer impact 40% energy reduction 75% reduction in sludge hauling costs 35% reduction in cost for out-sourced plant operations/ maintenance Compliance Continued (volunteer) support for interim operations from Honeywell until new WWTP is on line Compliance with WQCD temporary operating permit Emergency operations 30

34 GB Pre-flood Plant Configuration 31 31

35 GB During the flood The purported island that the plant was on pre-flood remained as such during the flood 32

36 GB Post-flood Plant Configuration A new (poop) home with two swimming pools (just joking) 33 33

38 JW Closing Comments Hybrid (non-linear) design-build for emergency situations 34

39 JW Closing Comments Hybrid (non-linear) design-build for emergency situations Have YOU ever lived through a natural disaster? 34

40 JW Closing Comments Hybrid (non-linear) design-build for emergency situations Have YOU ever lived through a natural disaster? Regardless, what would you value? Basic necessities (medical, clean water, sewer, light, power, heat, food, shelter ) A sense of hope Observing real progress I just wanna go home, I just wanna go home! 34

41 JW Closing Comments Hybrid (non-linear) design-build for emergency situations Have YOU ever lived through a natural disaster? Regardless, what would you value? Basic necessities (medical, clean water, sewer, light, power, heat, food, shelter ) A sense of hope Observing real progress I just wanna go home, I just wanna go home! Starting sooner, finishing faster This worked for Lyons, and we were all thankful to have the opportunity to participate and help! 34
