Task 5 -During development of the projected retail service area demands we identified an error in the City provided pressure zone GIS data. The error is in the attribute table that describes the pressure zone name, code, and head number for each pressure zone. This table contained either old or incorrectly assigned head numbers. The pressure zone head was by HDR to distribute PSRC projected demographic data to each of Everett's pressure zones. These demographics serve as the basis for the demand forecast. Because the head numbers in GIS table were incorrect the distribution of demographics and demand s to pressure zones needed to be rerun before the demands could be used in the modeling. 2. Task 6-Conservation additional services and budget approved for conservation model customization and additional conservation measure scenarios. 3. Task 7-The modeling software analysis had to be changed to determine that the UW recommended version of PowerSim software would not run the UW provided model and then develop a workaround solution to the problem (8 hours). The scope was written assuming that HDR would use the 1999-2000 model which had been set up to run the Everett yield scenarios. However the UW provided an updated 2005 model that did not include Everett's yield scenarios. About 20 additional hours were then required to troubleshoot and run the revised model with Everett's yield scenarios. 4. Task 9-System Analysis schedule and budget impacts resulting from delay in receiving the hydraulic model demand information for calibration, inaccurate model demand allocations, and additional as-requested modeling services. The City requested that HDR take demand information and allocate demands to the hydraulic model. The estimated cost for these additional services is $3,220. Additional delay in receiving calibrated EPS model from Silver Lake. All three models are in different coordinate systems which complicates the following 1 8 tasks: model merge (Silver Lake, Mukilteo and Everett models), demand allocation, population of transmission line elevations and calibration.
