Glenbard High School District 87 is planning about $2.3 million worth of capital improvement projects at its four high schools over the summer.
The upgrades, which take place annually when school is not in session, include energy-saving measures, life-safety items and other building needs, officials said.
Here's a look at some of the major projects:
Glenbard North: Work crews will remove and replace the baseball field's backstop and first base foul pole and netting. Inside, variable air volume mechanical units, a type of heating, ventilating, air-conditioning system, will be installed in two school corridors.
Glenbard South: Previously allocated funding -- $390,000 -- for a new track and scoreboard is included in the list of 2012 summer capital projects. Bids are now being taken for artificial field turf installation, which is expected to be complete this summer. Variable air volume units will be added. Floor tile will be replaced in two classrooms.
Glenbard East: A panel on the school water tower will be replaced and existing wood timber retaining walls will be replaced with masonry walls in the school's receiving area. The HVAC system will be updated.
Glenbard West: The band room and food lab will be renovated.
Most of the work will be done by Hampshire-based Northwest Contractors, which was the lowest of eight bidders. Asbestos abatement, which will occur at all four schools, will be completed by Lemont-based Universal Asbestos.
All the work is expected to be substantially complete by Aug. 10.
