A Philosophy Committed to Protecting the Environment
As part of our LEED design commitment, Burns & McDonnell focuses on protecting the environment by looking for opportunities to use recycled material and achieve waste reduction.
Our technical specifications have been redeveloped to incorporate construction materials with recycled content. Our general provisions contain clauses either requiring or encouraging contractors to recycle waste from demolition and construction operations.
Our facility designs often include areas dedicated to the separation, collection and storage of materials for recycling. Renovation projects maximize building and materials reuse.
Examples from recent projects:
- Rehabilitating existing aprons, runways and roads by recycling existing asphalt and concrete and incorporating fly ash for new base coarse materials. This initiative has been applied to airfield upgrades at Tyndall Air Force Base, parking aprons at Scott Air Force Base, and pavement rehabilitation and replacement at Kansas City International Airport.
- Recycling steel from demolition. At Langley Air Force Base, all structural steel was collected and recovered for recycling from the demolition of three large aircraft hangars.
- Specifying recycled materials for carpet products, gypsum products, thermal insulation, glass and glazing, acoustical ceiling tiles, and plywood and oriented strand board. When using Unified Facilities Guide Specifications, we have modified sections to allow or exclusively specify these recyclables that are competitively and commercially available.
- Reusing recovered underground storage tanks for road culverts
- Using shredded tires and wood chip waste byproducts in drainage layers in landfill construction at numerous municipal landfills in Kansas, Missouri and Nebraska.
- Recovering methane gas from landfills to fire heater boilers in adjacent facilities.
- Using heat recovery steam generators in manufacturing and processing industries.
Life Cycle Costs and Energy Conservation
Burns & McDonnell approaches all projects with a focus on identifying and providing the appropriate solution for the client, which considers system effectiveness from a first cost and operational standpoint, as well as anticipated system life and client budget. Life cycle costs can be a key predictor of sustainable design, as energy use and material and replacement requirements are factors considered in costs.
