Sound Transit Puyallup & Sumner Stations Access Improvement Projects

Sumner, Washington

Project Type:

Civil, Light Rail, Station, Design, Build

SCL Project Role:

Cost Estimator & Scheduler

Project Description:

To improve accessibility to the Sumner and Puyallup Commuter Rail Stations of Sounder, Sound Transit implemented a project aims to enhance convenience and ease of access for pedestrians, bicyclists, and drivers. A significant aspect of the project focuses on improving parking garages within a quarter-mile radius of the stations. These enhancements are intended to provide better access for Sounder commuter rail riders, benefit the local community, and contribute to a healthier environment. Phase 1 of the project has already been completed and included various access improvement options, such as improved transit connectivity, upgraded parking facilities, and enhanced bicycle and pedestrian access. Additional phases, Phase 2 and Phase 3, will be implemented to identify and implement further access improvements. This project represents a notable effort to foster improved accessibility and sustainability in the region.

Scope of Work:

SCL was responsible for providing cost estimating and scheduling services for access improvements to two heavily used transit stations in Pierce County. This included extra parking, structured parking garages, as well as associated site improvements and modifications to utility and street lighting. SCL also provided preliminary engineering design class 3 cost estimates, which facilitated the incorporation of pedestrian bridges at both stations and the navigation of BNSF right of ways for safe access between the parking garages and train platforms. The cost estimating methodology involved performing estimate takeoffs using RS Means, CSI format and developing Class 1 estimates based on reliable resources and tax rates. Additionally, SCL conducted estimate risk assessments and reviewed the schedule objectives from conception to final design to ensure effective project controls for the upgrades at Sumner and Puyallup stations.
