PART 1 - GENERAL

1.1 SUMMARY

A. This section includes general requirements and procedures for compliance with the Federal Sustainability requirements. This project is not seeking LEED™ certification but shall comply with the applicable Federal Sustainability requirements. These requirements include laws (Executive Orders and regulations), management policies, building codes and standards, Federal directives, and NPS guidelines.

B. Many of the Federal requirements can be achieved only through intelligent and integrated design of the project and are beyond the control of the Contractor. However, certain requirements relate to the products and procedures used for construction. Therefore, the full cooperation of the Contractor and subcontractors is essential to successful compliance with the Federal requirements.

C. Contractors shall familiarize themselves with the relevant requirements and provide the necessary information and instruction to all subcontractors and installers.

1. Some requirements involve quantifying percentages by weight; these require careful recordkeeping and reporting by the Contractor.

2. See http://www.nps.gov/dscw/ds-sustainability.htm for a list of Federal Sustainability requirements. The applicable Federal Sustainability requirements are also summarized on the project’s NPS Project Sustainability Checklist. Contractor is responsible for providing the necessary information in the “Construction” column of the checklist.

D. Related Sections:

1. See Divisions 01 through 49 Sections for sustainability requirements specific to the work of each of these Sections.
