Construction and Demolition Policy

Construction and Demolition Policy

Middlebury has established best practices directives for construction and demolition contractors working for the College to ensure that hazardous and nonhazardous waste generated from demolition and construction on campus are managed to reflect our commitment to environmental mindfulness.

Best Practices for Campus Construction and Demolition

The following practices are intended to provide an overall framework for construction and demolition waste management at Middlebury College. Individual projects require specific directives regarding waste material. The College will provide these specifics to the contractor on a project basis. These specifics will be established prior to the bidding process and will be included in project specifications as well as in contracts with general contractors and subcontractors. All contractors will be expected to uphold this commitment to waste management to support the College’s overall mission in this area.

Practice 1:  Predemolition Audit (if necessary)

An audit will be conducted by staff of the College (and a hired contractor if necessary) prior to any demolition project. All materials within a site will be documented by both location (floor plan) and quantities. It will be determined through the audit whether any materials may be reused by architecture salvage operations, the College, or private citizens. A walk-through inspection will include someone with “salvage/reuse” expertise who understands the value and market for architectural and other salvage materials. At this time, it is necessary to assess the need for a hazardous waste abatement plan. If a plan is determined to be necessary, the section on hazardous waste in this document lays out the best practices for hazardous waste abatement.

The following questions will be used as a guide for the predemolition audit. A plan will then be approved by College staff and communicated to all contractors:

  • What can be reused (reclaimed) on-site for new construction, (e.g., asphalt, glass, landscaping materials)?
  • Are there items of value to community, staff, and alumni?
  • Are there items (furniture, fixtures, moldings, mechanical equipment, etc.) that have immediate value to a secondary market?
  • Are there hazardous wastes on-site? Is an abatement plan necessary?

Practice 2: Construction and Demolition Waste Management by Material

At the onset and as needed (preferably again at the mid-point and at the end) during any construction and demolition project at the College, a series of meetings will be held with Addison County Solid Waste District, College officials, and all contractors to review expectations, rules, and regulations that must be followed. A review of the consequences (described in Practice 6) will also be included at these meetings.

Best Practices for Hazardous Waste Management

Practice 3: Abatement Plan

Should any contractor encounter hazardous waste during a project, a College official must be contacted immediately to ensure material is handled properly. Hazardous waste abatement contractors are hired for abatement of hazardous wastes by the College. The practice will include multiple sweeps of the site for removal of materials. College staff will participate to ensure hazardous materials that may be improperly labeled or located somewhere out of sight are not overlooked. Abatement contractors will be subject to the same quality control practices, as outlined in the section on Quality Control and Consequences, that apply to all construction and demolition projects.

Practice 4:  Hazardous Wastes Accepted by ACSWD

The following lists make explicit what is accepted by the local solid waste district and what is not. The lists are updated periodically. The College and its contractors are ultimately responsible for the correct disposal of these materials. Noncompliance will result in consequences, outlined in the section on Quality Control Best Practices, that apply to all construction and demolition projects.

Materials forbidden in trash, metal, or construction and demolition loads brought to the Addison County Solid Waste District transfer station:

Free-flowing liquids of any kind; latex or oil-based paint, liquid or dried (truly dried latex can be landfilled); paint-related products such as thinner or additive; pesticides; cleaning chemicals, liquid or solid; pool chemicals, liquid or solid; industrial/contractor-related chemicals including solvents, coatings, tars, and adhesives; federally listed hazardous wastes; friable asbestos; automotive chemicals (e.g., brake fluid, etc.).

The following materials are accepted at Addison County Solid Waste Management District transfer station if separated:


Batteries, automotive and household; motor oil; empty pressurized cylinders (e.g., propane, welding gases); fluorescent lightbulbs or fixtures containing PCB ballasts; mercury-containing thermostats, thermometers, barometers; appliances (charge of $3 per item—delivered separately); nonfriable asbestos (additional fee and proper packaging); tires.

Quality Control Best Practices

Practice 5: Contractor Accountability

At the onset of a construction and demolition project, the contractor is required to issue a plan for handling materials outlined in Practice 2, as well as hazardous materials to be used on-site.  The plan will include

  • Material(s)
  • List of Use(s)
  • Materials Safety Data Sheets (if required)
  • Storage on-site
  • Disposal plan/clean up at end

Documentation of proper management and disposal of all materials including hazardous waste is required before any payments will be released to contractors.

Practice 6: Consequences

Failure to adhere to the practices outlined in this document will result in the following fines (as appear in the contract):

  • $1,000 per incident fined by Middlebury College
  • Additional fines levied by outside parties (i.e., Addison County Solid Waste District, Clean Harbors, state of Vermont)
  • Cost of any cleanup plus 15 percent
