Modern builders have long dealt with environmentalists when planning projects. They used to often be at odds with each other, but times have changed. Many builders now employ their own specialists, and some of them proudly specialize in environmentally friendly construction. This includes the building, the materials, the landscaping, and it may even include how traffic is controlled to get people in and out of a particular area. It all contributes to the new ways buildings are designed and created. It also helps keep the environment healthy in the construction area and reduces some maintenance.
