Task completion

Task completion is an evaluation of planned maintenance tasks for specific activities compared to how many of those tasks were completed and is one of two metrics WSDOT uses—along with Level of Service—to determine the performance of its maintenance activities. This performance measure focuses on the amount of work that is completed in a defined, optimal maintenance program. This can be viewed similarly to keeping up with the oil changes, tire rotations, and other maintenance tasks to keep one's car in good condition per the maintenance schedule in the owner's manual. The amount of work completed is simply measured and reported as the percent of required maintenance completed in a given timeframe.

Note: The long term affects of COVID-19 such as work restrictions, furloughs, hiring freezes, budget reductions, increased costs for material, equipment and parts and personnel shortage is still having an effect various work activities. 1 Pavement and bridge asset conditions are given as percentage of WSDOT owned highway lane miles in fair or better condition (pavement) and percentage of WSDOT owned bridges in fair or better condition by bridge deck area. Pavement data lags one year behind indication (i.e., 2022 column corresponds to 2021 data). Pavement is part of an integrated approach using Washington State Pavement Management System condition rating, which takes into account all maintenance and preservation work completed and/or needed. 2 As of June 2022, 92.6% of WSDOT-owned bridges by deck area were in fair or better structural condition, declining from 93.2% in June 2021. Despite the drop WSDOT met its annual goal of having at least 90% of its bridges by deckarea in fair or better condition. 3 Pavement rating fell from 93% to 92% for details refer to Pavement Preservation article on page 7. 4 Percentages greater than 100 indicate more maintenance was completed than planned, due to backlog. 5 NPDES stands for the National Pollutant Discharge Elimination System. 6 For 2022 reporting period, urban tunnels are represented by both the SR 99 and I-90 tunnels for LOS and task completion

Note: COVID-19 work restrictions, furloughs, hiring freezes, budget reductions, increased costs for material, equipment and parts and shortage of personnel affected various work activities. 1 Pavement and bridge asset conditions are given as percentage of WSDOT owned highway lane miles in fair or better condition (pavement) and percentage of WSDOT owned bridges in fair or better condition by bridge deck area. Pavement data lags one year behind indication (i.e., 2021 column corresponds to 2020 data). Pavement is part of an integrated approach using Washington State Pavement Management System condition rating, which takes into account all maintenance and preservation work completed and/or needed. 2 As of June 2020, 93.8% of WSDOT-owned bridges by deck area were in fair or better structural condition, improving from June 2019 when 92.9% of bridges by deck area were in fair or better condition. The improvement was largely due to the removal of the Alaskan Way Viaduct from WSDOT’s bridge inventory. 3 Pavement rating jumped from 91 to 93% due to multiple concrete projects being substantially complete in 2019; the rating also includes chip seal ratings for the first time in many years. 4 Percentages greater than 100 indicate more maintenance was completed than planned, due to backlog. 5 NPDES stands for the National Pollutant Discharge Elimination System. 6 Urban Tunnel Systems Operations is represented by the SR 99 tunnel for 2020, the I-90 tunnel is not included in 2020 calculations, because the facility was still under construction during the reporting period. For 2021 reporting period, urban tunnels are represented by both the SR 99 and I-90 tunnels for LOS, for task completion the SR99 tunnel is was used solely, as the I-90 tunnel continued to be affected by construction. 7 The Regulatory/Warning Sign and Guide Sign Maintenance categories were not conducted in 2020 due to COVID-19 and carpooling restrictions. 8 This activity is a subset of the Guardrail Maintenance activity.

Note: 2018 data has been revised. 1 Pavement and bridge asset conditions are given as percentage of WSDOT owned highway lane miles in fair or better condition (pavement) and percentage of WSDOT owned bridges in fair or better condition by bridge deck area. Pavement data lags one year behind indication (i.e., 2019 column corresponds to 2018 data). Pavement is part of an integrated approach using Washington State Pavement Management System condition rating, which takes into account all maintenance and preservation work completed and/or needed. 2 Structural bridge repairs completed went up in 2017 as deck repair work completed went down due to the limited work time available for bridge crews. The crews prioritize the most critical work whether it is deck or structural. 3 For the first time in 10 years WSDOT has been able to reduce the backlog of P1 priority repairs due to supplemental funds from Preservation and Connecting Washington. 4 NPDES stands for the National Pollutant Discharge Elimination System. 5 Urban Tunnel Systems Operations is represented by the I-90 and as of 2019, the SR 99 tunnel is included in the activity. This activity has been removed from 2017-2019 calculations because the facilities in that category have been under construction during the reporting period and are not included in calculations of percent of targets achieved. 6 This activity was a subset of the Guardrail Maintenance activity in previous reports. 7 Intelligent Transportation Systems (ITS) has shown a 8.7% increase in total inventory through system additions since 2017. 8 Task completion for Intelligent Transportation Systems increased due to a revision in the recommended frequency for preventive maintenance for Closed Circuit Television Systems (CCTV). The task completion rate would have been 44% without the upward shift in preventive maintenance frequency. 9 Highway Lighting planned work includes the preventive maintenance work completed for highway lighting systems and electrical services. 10 Funded targets were reduced for this activity in 2019. 11 Task completion activities were updated in 2019.

Note: 1 Beginning in the 2013-2015 biennium, WSDOT is using only one type of unit measurement that represents the largest component of the pavement activity, rather than four different types of units used in the 2011-2013 biennium. Pavement data lags one year behind indication (i.e., 2018 column corresponds to 2017 data). Pavement is part of an integrated approach using Washington State Pavement Management System condition rating, which takes into account all maintenance and preservation work completed and/or needed. 2 Pavement and bridge asset conditions are given as percentage of WSDOT owned highway lane miles in fair or better condition (pavement) and percentage of WSDOT owned bridges in fair or better condition by bridge deck area. 3 Urban Tunnel Systems Operations is represented by the I-90 tunnel which was under construction during the reporting period and is not included in calculations of percent of targets achieved. 4 Structural Bridge Repair continues to show a decline in task completion for priority one repairs; WSDOT is emphasizing bridge deck repairs. 5 Structural bridge repairs completed went up in 2017 as deck repair work completed went down due to the limited work time available for bridge crews. The crews prioritize the most critical work whether it is deck or structural. 6 Task completion for Intelligent Transportation Systems increased due to a revision in the recommended frequency for preventive maintenance for Closed Circuit Television Systems (CCTV). The task completion rate would have been 44% without the upward shift in preventive maintenance frequency. 7 Intelligent Transportation Systems (ITS) has shown a 5.7% increase in total inventory through system additions, since 2017. In 2017 the percent of task completion was 56%, with 2018 being 52%. 8 Percentages greater than 100 indicate more maintenance was completed than planned. 9 WSDOT reduced its maintenance on bridge decks toward the end of fiscal year 2013 to avoid overspending the budget at the end of the 2011-2013 biennium. New funding for the 2013- 2015 biennium allowed crews to complete some of the backlog created in the previous biennium. 10 NPDES stands for the National Pollutant Discharge Elimination System. 11 This activity was a subset of the Guardrail Maintenance activity in previous reports. 12 Raised/Recessed pavement marking maintenance tasks significantly decreased due to budgetary and equipment challenges. 13 Highway Lighting planned work includes the preventive maintenance work completed for highway lighting systems and electrical services.
