4 Ton Horizontal Wet-back 3 Pass Steam Boiler
Scope of works
1. Supply , deliver, install, test and commission the above mentioned tanks, their piping and pumps as follows a) 6 (six ) of the tanks to be install at the building top where the current tanks that serve the kitchen and laundry sit. Out of the six tanks, three will be connected to serve the purpose which the current installed tanks serve i.e. to supply water for use in kitchen, laundry and fire extinguisher. Inlet of the three tanks to be the inlet of the existing tanks. Remaining three tanks serve as boiler reservoir tanks and should be connected as such. The inlet of these three tanks to be from two sources i) From the kitchen/laundry tank inlet pipe. ii) A provision is made that will be used as an inlet from a main water tank that is currently under procurement process. All the 6 tanks to be isolatable, by way of valves, such that it is possible to prevent entry and /or exit of the tank content. Piping from these tanks is such as to feed the boiler day tank situated inside the mezzanine floor in the boiler room. Current pipe sizes to be maintained.
2. Dis-assemble the existing tanks system to give way for the installation of the new incoming tanks system. The work to be in such a manner as to avoid disrupting kitchen/laundry service delivery as much as possible.
