Tank Installation - Nicholson Plastics Ltd

Site Check List
In the U.K. all products are offered with a full tank erection service. An experienced team will build your tank and leave it ready for commissioning. However customers should observe the following check points before calling our staff to site:

DIMENSIONS
To obtain overall tank sizes, add the following to the nominal internal dimensions:a) For 1m module tanks add 160mm to length, width and height. b) For 1.22m module tanks add 170mm to length, width and height.


TANK SUPPORTS
These are required in ONE DIRECTION ONLY: metric tanks at 1 m centres, imperial tanks at 406mm centres. Support must be level and extend to the full EXTERNAL width of the tank plus 200mm. If built on a platform with no access to bolts underneath, we must be advised in advance and an internally flanged base will be supplied.

ACCESS
Space is required all round for ease of erection, unless the tank is internally flanged. The minimum requirement is the overall size plus 9OOmm. Tanks can be built in tighter spaces, but, if this prevents access to bolts for future maintenance, we cannot accept liability, and our erectors will require written authorisation before starting work. Return visits to site, if required, will be charged at our normal rates. Other checks to be made include: access to the tank room; and any obstructions such as pipework or ducting.

HOISTING AND SERVICES
The contractor is responsible for hoisting the panels to within 6m of and on a level with the final position. If required, the contractor will also provide scaffolding, light and power free of charge.

HEALTH AND SAFETY
We reserve the right to refuse to carry out work in unsafe conditions.
Our erectors will observe site safety rules under relevant national and local health and safety regulations. Please ask for our Method Statement Sheet for further information.

DELAYS
We reserve the right to make additional charges for delays caused by preparatory work not being completed in accordance with our requirements.

PIPE CONNECTIONS
Pipe connections are fitted at site at the time of installation to agreed positions and to conform to water regulations/byelaws.

FILLING AND TESTING
This should be done as soon as possible after the tank is built and in any event within the time specified in our Warranty Conditions. Our contract does not provide for a member of staff being present during filling.

CONDITIONS OF CONTRACT
All work is carried out under our Conditions of Sale as stated in our quotation. Extra copies are available on request.
