Westridge Summer Bond Projects Update
I would like to update the Westridge community on the progress we have made at the school. I invite you to a community meeting to be held on Monday, August 12, from 6 p.m. to 7 p.m. at Lakeridge High School to address any questions you may have after reading this update.
The purpose of renovating Westridge Elementary school this summer is to provide seismic upgrades, a new roof, a building addition, new mechanical upgrades, technology upgrades, security upgrades, and interior architectural modifications. Window replacement and siding replacement are also part of the work.
Progress to date:
Week of June 17: Work began on the building with the demolition of interior walls to prepare for seismic upgrades. Roof repairs, siding demolition and other exterior work began.
June 24: As demolition progressed, contractors found microbial growth on the sheathing of the exterior walls. This is typical for this building’s age and construction type, however we discovered more than anticipated. Contractors also found structural decay (i.e. dry rot) issues beyond what was anticipated based on pre-renovation/ exploration surveys conducted this spring. These exploratory surveys included hazmat and structural testing.
June 25: Bond staff contracted with an industrial hygienist and a restoration/remediation company to assess and remediate the microbial growth throughout the building. At the same time, the contractor and design team created a plan to address structural issues and to resequence work to allow for remediation and additional structural repairs.
The fungal remediation was conducted in accordance with the Guidelines on Assessment and Remediation of Fungi in Indoor Environments, 2008, published by the New York City Department of Health and Mental Hygiene, Bureau of Environmental & Occupational Disease Epidemiology, and ANSI/IICRC S500 Water Damage and Restoration, 2015.
Week July 1: TRC Environmental conducted air sampling throughout the entire building and provided remediation protocols for each space. Servpro used those protocols to remediate the fungal growth in the building. The contractor brought on additional trades people in order to meet the demands of the revised sequencing of work. Despite these constraints and the additional workload, we will open on time. All other aspects of the project, including mechanical, technology and exterior upgrades are proceeding as planned.
Based on the new information gathered this summer, we anticipate the following scope of work for next summer, which would include:
Replacement of ground level exterior brick
Permanent repair of covered play area
Questions & Answers
1. Will Westridge open on time? Yes. School will start as scheduled. The discovery of the flawed exterior design that allows water to intrude and the permanent repair of the outdoor play area, will require a second phase of work that will take place next summer. The new classroom addition and makerspace may still be under construction when school starts.
2. Were students and staff open to mold? No. The microbial growth was encapsulated inside of the exterior walls.
3. Will the building be safe to re-enter at the start of school? Yes. The building has been deemed safe to occupy by TRC Environmental. Monitoring protocols will be followed in order to ensure student and staff safety throughout the year. Structural repairs have been completed and seismic work proceeds as planned.
4. How will mold and dry rot be avoided in the future? When the building’s skin is replaced next summer, a high performance exterior assembly will be used. Significant improvements in mechanical systems will allow for increased air circulation and ventilation.
5. Does the District have an indoor air quality policy? Yes. LOSD follows all EPA requirements and Oregon Healthy Schools Act requirements for clean and safe air inside of schools.
6. How did this happen? Moisture invaded the building over the past 40 years. Westridge was built in 1980. Technology has changed substantially which will prevent water intrusion in the future. We expected some microbial growth and structural damage, but not to the extent we found.
