1. 1 Wide Area Network Project Information Technology Advisory Committee March 21, 2007

2. 2 WAN Project ITAC Update Deliverables from February 21, 2007 ITAC meeting GIS Route mapping of, Modified “new build” GIS Route mapping of, Modified “new build” with possible shared fiber assets identified on route maps GIS Topographic map of BVSD WAN serving area Estimated linear lengths of a new build High level budgetary cost of a new build “Turn Key RFP Approach” List of network devices for BVSD List of future applications for BVSD The Greaves Group Study – Americas Digital Schools 2006 Bandwidth forecast base on BVSD enrollment and network device inventory Project Task List ALL action item have been completed

3. 3 WAN Project Progress Update Infrastructure reviews, shared resources meeting –City, County, CU, UCAR, Broomfield, Longmont, Lafayette, Celestial and Louisville Developing/Acquiring RFP templates –BVSD Terms and Conditions –High level specifications –Developing construction methods document Engineering routes to reduce linear lengths Data acquisition, hand holes and splice points (City) Developing sample Bill of Materials (BOM) Develop ring configurations Identifying “high cost” locations e.g. fiber routes vs. wireless High-level budgetary build costs

4. 4 Future WAN Requirements Future high bandwidth educational and security applications: Discovery Learning – Streaming Media IP Television distribution Distance learning – video conferencing Video Security Web-Based Testing and Intervention Centralized Data Applications Off Site Data Warehousing Alternate Data Center – Disaster Recovery Centers Network Redundancy Internet II

5. 5 WAN Requirements Existing applications Infinite Campus Lawson financials File sharing Email Internet

6. 6 Data Network Bandwidth Analysis INTERNET ONLY Using the forecast published by the Greaves Group and the BVSD student enrollment and facilities data indicates BVSD needs for more than a Gigabit network in less than 4 years years based on Internet usage only Based on a study by the Greaves Group, which estimates Internet usage of 2.9kbps per student in 2006, each school would use 13.1Mbps, 21.4Mbps, and 36.6Mbps for Elementary, Middle and High Schools, respectively, with a district-wide total of 975Mbps Digital Schools estimate a need for 9.7kbps per student for Internet access in 2011, which comes to 15.6Mbps, 24.7Mbps, and 43.7Mbps, with a district total of 1.15Gbps The Greaves Group study suggests a more likely Internet bandwidth requirement at 40.0kbps per student in 2011, resulting in 27Mbps, 39.6Mbps, and 76.3Mbps, and a district total of 1.94Gbps High-bandwidth applications such as video conferencing, webcasts, video security, and web-based testing can dramatically increase thesenetwork bandwidth requirements

7. 7 Data Network Bandwidth Analysis INTERNET ONLY 2006, district-wide 975Mbps 2011, district-wide 1.15Gbps 2011, Greaves district wide 1.94Gbps Existing applications and new high- bandwidth applications will undoubtedly increase the figures four fold

8. 8 Route Mapping New Build Linear Lengths –West Ring @ 288fc210,364 LFT –East Ring @ 288fc178,554 LFT –Lateral Builds @ 24fc70,361 LFT –Campus Build @ 288fc1500 LFT TOTAL New Build460,779 LFT Total Miles87.26 Miles Lengths will have minimal change to allow access to other agencies (Nederland Build 32.9 Miles 174,240 LFT)

9. 9 Route Mapping (cont.) New Build Assumptions ESTIMATED COSTS All construction under ground - directional bore or trenching Customer provided ISP and FTP enclosure All locations less 4 Nederland Schools 2 ring 2 ISP POP ring topology WAN not included in estimated budget No recurring costs e.g. locating break – fix, Capital Expense Only BVSD FTE’s not included +/- 10% on construction and materials cost +/- 2% on engineering and construction management

10. 10 Route Mapping (cont.) New Build ESTIMATED COSTS Aerial Vs. Underground Facts Directional bore - Most expensive Trenching – Less expensive Plowing – Least expensive Aerial – Construction less expensive Pole attachments monthly yearly rental Pole replacement at customer expense Elements Access

11. 11 Route Mapping (cont.) New Build ESTIMATED COSTS (Blended Rate from Actual Projects) –Option 1 - Greenfield Build using the Turn-Key RFP approach $12,902,372 @ $28 per LFT –Option 2 - Greenfield Build using the CM and Material Procurement RFP approach $9,215,580 @ $20 per LFT Additional savings utilizing aerial construction methods where applicable –Option 3 - Green Field Build with Owners Engineer Approach RFP for Construction Only $7,372,464 @ 16 per LFT, CM, $525,000, Engineering and Permitting, $490,500 Total - $8,497,464 Additional savings utilizing aerial construction methods where applicable –Nederland Build$8,363,520 Termination Hardware Not Included

12. 12 Route Mapping (cont.) City, CU, BRAN –Available Dark Fiber (TBD) –Available Existing Conduits (TBD) –Future Builds TOTAL Combined Identified 313,469 LFT Total Miles 59.36 Miles

13. 13 ITAC Discussion Steps Determine Ring Topology and Alternate Services Connecting east and west facilities Redundancy options e.g. fiber pair/ring to each facility vs. daisy chain –Loss of data rate for multiple hops vs. 10 gigabit dedicated –Switch technology –Fiber specifications

14. 14 Recommended Next Steps 10 year financial feasibility analysis Determine ongoing expensed –Locating cost –Internet –Break – Fix –Mountain Schools –Network termination equipment and maintenance –Services vs. Ownership delta less E-rate –E-rate eligibility would remain for Internet and Nederland Schools –Construction management –Engineering –Materials –E-rate deficit correction – long term savings/loss analysis

15. 15 Recommended Next Steps (cont.) Determine RFP Strategy Option 1- Turn Key RFP Option 2 - Engineering, Permitting and Construction Only – Option 2 –Remove Materials and CM to ensure savings from mark-ups Option 3 - Green Field Build with Owners Engineer Approach RFP for Construction Only Develop Draft RFP – based on ITAC feedback
