Cedar Lane Water Tower Foundation Repair
Baxter & Woodman provided design, bidding, and construction engineering services for repairs to the Village of Northbrook’s 500,000 gallon elevated water storage tank located at 1225 Cedar Lane. The tank was constructed in 1954. Severe cracking, delamination, spalling, and disintegration of the cast-in-place concrete foundation ring wall was caused by years of exposure to freeze-thaw cycles. The deterioration resulted in a significant reduction of the effective depth and capacity for anchors between the steel tank base and concrete foundation wall.
Selective demolition of deteriorated concrete, installation of confinement reinforcing steel, and placement of cement-based patching material were necessary to restore the structural integrity of the foundation wall and tank anchorage. Soil placed over the footings was required to resist overturning due to wind loading, and excavation for construction needed to be completed in 36 equally spaced segments. The Village required that the tank and telecommunications facilities remain in service during construction.
Baxter & Woodman prepared bidding documents, assisted with public bidding process, and performed construction administration and inspection services. The engineering and construction were completed within the Village’s budget in less than 6 months.
