Scope of Work The Chinese Pavilion is part of the National Bonsai and Penjing Museum at the U.S. National Arboretum. The steel and concrete block structure has a lightweight removable roof system made of aluminum and polycarbonate panels that are stored in the basement of the pavilion during the growing season. Access to the basement is from the garage door located on the east side of the building. The interchangeable roof panels are removed and stored and stacked on end in the southern part of the basement each spring and re-installed each fall. In the fall, the roof panels are set in place to maintain a protective structure for the winter. There are four (4) ridges that run east to west. There are 16 interchangeable panels and 8 end panels for each ridge.

NOTE: Due to light nature of the panels, it is important that they are secured at the end of each work day. Also care should be exercised when carrying the panels so that they are not lifted due to wind.

The roof panels are light and can be carried by one person normally; however, some may require two people. Panels are to be hand carried from the basement in the fall and set in place.

Matching aluminum strips are used to anchor the roof panels so they stay in place. In the spring the reverse procedures are used to remove the roof panels.

The Arboretum requires a qualified contractor to remove the roof panels in mid-April and to re install the roof panels in early-November time frames. These times are approximate and will be determined by COR dependent on ambient temperatures.
