Construction Updates


Construction for New Driveway to 40th Avenue Begins Aug. 15

From Aug. 15 to Aug. 24, a portion of sidewalk on the east side of 40th Avenue NE, between the existing Emergency Department (ED) driveway and the Metro route 65 bus stop, will be closed as construction crews build a new ED driveway. This work is the first phase of a larger, phased project to construct a modified ED drop-off area.

Pedestrians will have two options for safely maneuvering around the construction zone:

  • Use the temporary walkway that will be fenced through the Forest service drive and ambulance bay. It will connect with the existing walkway to 40th Avenue that runs along the ED driveway; or
  • Cross to the west side of 40th Avenue in a designated crosswalk.

Please be safe and use only designated pedestrian paths and crosswalks.

Additionally, the landscape island within the existing ED driveway will be removed during that same period. The existing ED driveway will remain open.

This work will occur from 8 a.m. to 6 p.m. weekdays, and 9 a.m. to 6 p.m. Saturday, Aug. 18. Normal levels of construction noise are anticipated.

Vestibules to Be Installed at Seattle Children’s Hospital Emergency Department and River Entrances

Originally posted July 24, 2018. Updated Aug. 2, 2018.

Crews will build and install vestibules at the Emergency Department (ED) and River entrances on Seattle Children’s hospital campus. The vestibules are being installed in preparation for construction of Building Care and will help remove dust and soil from people entering the hospital.

The ED vestibule will be built in the Forest service drive area (near the southwest corner of the hospital) between July 24 and Aug. 8, then installed at the ED entrance between Aug. 9 and Aug. 14. All work to build the vestibule will take place between 8 a.m. and 6 p.m. weekdays, and 9 a.m. to 6 p.m. Saturdays; normal construction noise levels are anticipated. On Thursday, Aug. 9, construction crews will move the vestibule into place at the ED entrance with a forklift from 5 to 7 a.m.; the forklift will create minimal noise. This early time period was chosen to minimize disruption to patients and families using the ED entrance. Once in place, installation of the vestibule will continue through Aug. 14 during standard working hours. The ED entrance will remain open during installation.

Work on the River vestibule will take place between July 26 and Aug. 7. To minimize hospital access impacts, the River entrance work will occur at night, between 8:30 p.m. and 4:30 a.m. weekday nights. Construction lights will be used at the River entrance, and minimal construction noise levels are anticipated. We do not expect noise or lights to impact the hospital’s neighbors.

Construction Work on Helen Lane Scheduled for Aug. 8 to Sept. 14

From Wednesday, Aug. 8, to Friday, Sept. 14, construction crews will modify Helen Lane at Seattle Children’s Hospital. Helen Lane is the road that serves the hospital’s River entrance.

The purpose of this work is to straighten Helen Lane, which will then serve as the new hub for Seattle Children’s workforce shuttles. Portions of the existing curb along Helen Lane will be removed so the road can be straightened, then new curb will be poured. Some work will also occur around the traffic circle near the River entrance. Helen Lane and the River entrance will remain open during construction.

Normal levels of construction noise are anticipated. Work will occur between 8 a.m. and 6 p.m. on weekdays, and 9 a.m. to 6 p.m. on Saturdays.

Please contact with questions or concerns.

Seattle Children’s Announces New Odessa Brown Children’s Clinic

Preliminary sketch of Odessa Brown Children’s Clinic at Othello

Seattle Children’s today announced it will be opening a new Odessa Brown Children’s Clinic (OBCC) adjacent to the Othello Link light rail station in the Rainier Valley. OBCC is a community clinic that provides medical, dental, mental health and nutrition services to all families, regardless of their ability to pay. OBCC has been committed to delivering equitable health and wellness care to lower-income and ethnically diverse children for nearly half a century.

The new clinic will be approximately 35,000 square feet to meet the wellness needs of the growing pediatric population in south Seattle and south King County. Services at the Othello location will include pediatric medical care, mental health, dental services, nutrition, sports medicine, physical therapy, and occupational therapy.

The clinic will also be part of a unique urban community concept called “Othello Square,” a 3.2-acre site that will provide families with convenient access to services, such as a charter high school, an economic opportunity center, a computer lab, an early learning center, affordable retail and commercial spaces for rent, community meeting spaces, and mixed-income housing for rent and ownership.

Seattle Children’s plans to break ground on the new clinic in 2019. Read more about the new clinic in our press release. The original OBCC, located in the Central District, will be renovated to upgrade its clinical facilities and maintain its cultural heritage in the community. The clinic will continue to serve families in the Central District and adjacent neighborhoods, as well as communities to the north and west.

Building Cure Concrete Topping Out

Building Cure is soon reaching a significant milestone: completion of the concrete structure. There are just five final placements needed to get us through the remainder of the concrete structure work, which will take place on July 27, 30 and 31, and Aug. 2 and 6; crews will set up at approximately 4:30 a.m. on these days. Once the concrete structure is in place, the large concrete placing boom and mobile pump trucks will go away, and the team will move to setting the steel structural penthouse at the very top of the building, and installing exterior glass and interior finish activities.

Over the weekends of July 28 and 29, Aug. 4 and 5, and Aug. 11 and 12, crews will place mechanical units onto the top floor of the building. The units will be placed with the tower crane; no impact is anticipated to pedestrian or vehicular traffic near the site, aside from occasional flagging to assist trucks entering and exiting the jobsite. Please follow the direction of flaggers and detour signage this weekend, as they are in place for your safety.

Modular Removal Work Taking Place in June on Seattle Children’s Hospital Campus

Modular buildings located on Seattle Children’s hospital campus are being removed in sections via Penny Drive. Work to prepare for removal will take place between June 11 and 23: Monday through Friday, from 7 a.m. to 6 p.m.; Saturday, from 9 a.m. to 6 p.m.; no work will take place on Sunday. No work causing any noise will occur after 5 p.m. or before 8 a.m. weekdays, or after 5 p.m. or before 9 a.m. Saturdays.

The physical move of modular sections down Penny Drive will take place two to three times each day: 1:30 p.m. on Thursdays, Fridays and Saturdays only; and 6 and 8:30 p.m. Mondays through Saturdays. Transporting modular sections down Penny Drive should not cause significant delays, but if we experience traffic congestion, the Ocean garage exit to NE 45th Street may be opened for a brief time to prevent delays to patient and family departures.

Terry Avenue Closed April 28 and 29 for Building Cure Construction Activities

Building Cure reaches a significant milestone April 26 with the placement of the Level 7 columns. Once placed, we’ll have made it to the halfway mark for the above-grade building structure. Including the structural work below grade, 11 floors of building structure have been completed, representing approximately 400,000 square feet of space for Seattle Children’s quest to eliminate childhood disease. Twelve contractors working on-site and across teams have completed more than 225,000 hours of work on Building Cure.

This weekend, crews will place mechanical units onto the second floor of the building. To facilitate their placement, a large mobile crane will be set up on Terry Avenue on April 28 and 29. Work will begin at 8 a.m. each day. Terry Avenue will be closed to vehicle traffic, and a detour will be set up to adjacent streets. The sidewalk on the east side of Terry Avenue will be closed to pedestrians. Foot traffic will be diverted to the sidewalk along the west side of Terry Avenue, which will remain open. Please follow the direction of flaggers and detour signage this weekend, as they are in place for your safety.

An Update on Seattle Children’s Research Institute’s Downtown Campus Expansion

Seattle Children’s Research Institute is beginning the Master Use Plan (MUP) process for Research Building 4 (RB4), which would be located between Virginia Ave. and Stewart St., adjacent to Boren Ave. The MUP process will begin with Seattle Children’s submitting an Early Design Guidance (EDG) package to the City of Seattle on April 23.

As another key component in our journey to treat, prevent and cure pediatric disease, the building would add approximately 600,000 sq. ft. of research, clinical and administrative space. Next to the institute’s Building Cure facility which is currently under construction and slated to open in 2019, it will be the fourth building owned by Seattle Children’s on our downtown campus.

Construction of RB4 would begin after Building Cure is close to being at space usage capacity. While there is no exact timeframe for when that will occur, we are starting the RB4 MUP process now to plan for our future growth.

Modular Trailer Removal and Installation Taking Place Saturdays, March 3 and 10

On Saturdays, March 3 and 10 between 8 a.m. and 4 p.m., work will take place at Seattle Children’s on the south side of the Forest loading dock to remove old modular trailers and install new ones. A crane will be placed near the ambulance bays to complete this work, and some street parking along 40th Avenue NE will be unavailable during work hours to enable safe removal and installation of trailers, and easy entry and exit for ambulances. Normal noise levels are expected. For questions or concerns, please call the construction pager at 206-469-5860.
