  1. BACKGROUND

The South Coast Sewage Treatment Plant is responsible for treating all sewage from the south coast sewered network before it can be disposed of through a piped outfall, into the marine environment. The plant consists of varying screening elements that remove debris and solids from the sewage flow. As sewage flows through the plant, varying levels of hydrogen sulfide (H2S) gases are released into the plant. These H2S gasses are highly corrosive, and have caused the degradation of numerous doors as well as door jambs of both the treatment building as well as the administrative building at the facility.

 

  1. DESCRIPTION OF WORKS AND SPECIFICATIONS
    • Single and Double Doors
  • Supply and install all doors significantly impacted by corrosion, with new or doors

constructed from grade 304 or 316 stainless steel grade or other material suitable for use in corrosive wastewater environments.

  • Make good all doors, door jambs, door hardware, major defects and door locking mechanisms.
  • All doors should be capable of withstanding a Category 2 Hurricane or similar wind speeds.
  • Doors to be reinforced with grade 304 or 316 stainless steel strips or similarly approved vertical edges and horizontal bottom edges.
  • Replace, or repair where practical, corroded door jambs, and make good all walls and floors adjacent to the door Fair-faced blockwork to be retained as much as possible, with minor plastering being allowed where it has been necessary to make good any damages done to blockwork walls.

  • Preference will be given to doors with an electric operator and control systems, which are optimally matched to the door technology, and possess a soft start and soft stop function of the door curtain, which protects all door and operator components from wear.
  • Power driven doors shall be supplied with a direct drive operator and variable operator fitting as standard.
  • Doors should be equipped with a curtain and operator cover for effective protection against dirt and adverse effects of the weather.
