NOTES FOR ITEM NO 250 ABOVE:

The above item shall be quoted and executed on ground based on Contractor’s own design on Turnkey execution and Performance Guarantee Basis. The Performance Guarantee is related to achieving the indoor conditions, within the air-conditioned space as stipulated at Annexure-I. The contractor shall be responsible that the HVAC system installed based on his own design results into meeting all the parameters of desired indoor conditions, as specified at Annexure-I, as long as outdoor conditions are within the range (as specified at Annexure-1) during all seasons i.e. Summer, Winters and Monsoons on 24 hours operation round the year basis. The Contractor shall also be responsible for desired operational efficacy and desired efficiency of the HVAC System during its life cycle of minimum fourteen years. The specifications of Sub Systems of HVAC Installations given-here-in after (in Appendix II) are on Minimum Basis. In case Contractors design requires quantities & specifications lower than those specified. The Specified quantities & specifications shall be followed. In case contractors design require higher quantities & specifications the same higher quantities and specification shall be followed.

There are various space constraints at site. The Contractor is advised to visit the site of work and familiarize himself with these constraints before quoting the rates. Site visit may be arranged with prior intimation to Garrison Engineer (I) (Project) Kolkata. Irrespective of the fact whether the contractor has visited the site or otherwise, no claims arising out of not being familiar with site constraints shall be entertained later.

The Contractors must specifically note that Plant room is to be setup in an existing building nearby (approximately 25 Meters away). The capacity of plants equipments etc must take into consideration the losses in temperature of Chilled/Hot water in recirculation system. The extra cost of laying insulated pipe line from Plant room to main building also needs to be taken into consideration. Also the cooling towers of the AC pant are to be erected on the roof top of an existing building. The Contractor is advised to take all these constraints into considerations.

The successful Contractor shall submit the following documents within Four weeks of placement of work order, for approval of Garrison Engineer.

(a) Heat Load Calculations, separately for Summers, Winters and Monsoons. The Contractor should work out heat load based on the outside conditions prevalent at Barrackpore, Kolkata and desired inside conditions as specified at Annexure-I, taking into considerations the building plan, height, as given in the tender and arrive at the plant capacity to achieve the indoor conditions as given in Annexure I. In case the plant capacity as per his own calculations works out to be less than 50 TR, HVAC System of 50 TR Shall be provided. In case the plant capacity as per his own calculations works out to be more than 70 TR, he should refer the matter back to Department with all calculations and should not quote for tender, till final decision is communicated. In case any parameter required for HVAC design is missing, the Contractor shall obtain the parameter by visiting the site, with prior appointment with Garrison Engineer (I) (P) Kolkata. Achieving energy efficiency and least life-cycle cost shall be the guiding factor in the heat load calculations and the overall design of the HVAC System. Unnecessary additions to heat load and the capacity of HVAC System shall be avoided. For achieving energy efficiency of HVAC System the worst conditions of ambient Dry Bulb Temperature and Wet Bulb Temperature occurring concurrently for less than 0.4 %, (Percentile hours) as defined and stipulated in IS 7896:2001 and National Building Code(NBC)-2016 shall be ignored. i.e. As per stipulation in IS:7896:2001 and NBC-2016, the worst outdoor ambient conditions occurring on an average for less than 35 hours in a year shall be ignored. However Safety margins of 10% shall be considered in design as elaborated in Annexure-I

(b) Plan depicting layout of all equipments and Sub-systems of the HVAC System. This shall be self contained and self explanatory representation of layout of equipments and sub-systems. The dimensioned drawing of the site of work clearly marked with the space to be air-conditioned, AC Plant room and the AHU Rooms are forming part of the tender. The Contractor is advised to use the same drawings, for making the layout plan of all equipments.

( c) Schematic Diagram of the Electrical system: This shall contain specifications, sizes, current, voltage and fault levels ratings of all cables, switch gears and instrumentation & control systems and all interlocking.

(d) Dimensioned drawing indicating the Duct layout. – One tentative layout of proposed ducting arrangement is enclosed with the Tender. This drawing is for reference only and indicating the structural opening etc as are provided in the building to suit this layout. The Contractor must however prepare his own ducting drawings to suit his design and to achieve the conditions stipulated at Annexure-1. The duct design drawings Shall contain material of construction, sizes, thickness etc of all ducts, insulation materials, air diffusers, fire dampers etc complete in all respect. All design calculations in support of the duct design shall also be enclosed. The duct design submitted by the contractor shall be approved by the department. Any additions/alterations carried out by the department, prior to communication of approved duct layout as well as during the execution of work shall be carried out by the contractor at no extra cost to the department. All such additions/alteration shall, however be confined. All such addition/ alteration shall however be confirmed to the duct layout in the air conditioned space specified in the tender only, no new areas, not to be air conditioned in the guise of amendments in duct layout. All Civil works for making opening and making good the disturbed surface shall also be within the scope of work of this tender.

(e) Yard stick for making interim payments: This document is required for regulating interim payments (Running Account Receipts (RARs)) to the contractor. This shall contain the important stages in execution of the project up to provisional completion (Phase-1 test) and corresponding percentage (%) of the total lump sum amount quoted by the contractor, totaling up to 95 % of the total lump sum quoted amount. An amount of 5% of the total lump sum amount shall be retained by the department for Phase -II tests. This shall be released on successful completion of Phase-II tests only. The yard stick submitted by the contractor shall be for suggestion/ indicative purposes only. This shall be approved by the department and communicated to the contractor, within one month of placement of work order for AC work.

(f) The design and other technical details mentioned above at Ser No 249.05 to 249.08 shall be got vetted by the Contractor from any of the Indian Institute of Technology (IITs)/ National Institute of Technology(NITs)/Government owned Engineering College having Refrigeration & Air-Conditioning as one of Engineering stream at Graduation/Post-Graduation level OR from Corporate Office/ Head Office/ of any one of the approved Original Equipment Manufacturers i.e. VOLTAS /DIAKIN /BLUE STAR /HITACHI.

(g) All the documents/ technical details mentioned above duly vetted as specified above shall be approved by Garrison Engineer (GE) within 15 days of submission. The GE may approve the documents as submitted by Contractor or may suggest modification/ alteration in documents/ technical specifications duly supported with reasons for the same. The work shall be executed based on the approved documents. In case of any dispute the matter shall be referred to Accepting Officer. The decision of Accepting Officer shall be Final and Binding.
