Clarification#1 to Queries Raised RE: Supply and Delivery of Water Tanker Vehicles to the Barbados Water Authority

Ref: ICB No. Contract # 70/2019/GCF/Barbados/CCCCC: Response #1 to Queries Raised

We write with reference to paragraph 7.1 of the Instructions to Bidders (ITB) that addresses the subject of ‘Clarification of Bidding Documents’. In accordance with paragraph 7.1 of the ITB, a Bidder requiring any clarification of the Bidding Document shall contact the Centre in writing and the Centre shall respond in writing, provided the clarification is requested prior to the deadline for clarification. The Centre is also required to include in the response a description of the inquiry without identifying its source.

The queries received to date and Centre’s responses are as follows:

Query #1: A 4500litre / 1200 USG tank is a relatively small unit and would normally be put on a chassis, as opposed to being put on a trailer to be towed behind a tractor unit. This is not the norm and would add significant cost to the unit. Can we tender for a 5000 Litre/ 1500 USG Tanker?

Answer #1: Please see Addendum #1 to Bidding Documents. We have now amended the specifications as
follows:
i. “PART 2 – SPECIFICATIONS FOR TRACTOR VEHICLES” to read: “2b. Truck Unit Specifications for 1,200 – 1,600 USG tanks.”
ii. “PART 3 – SPECIFICATIONS FOR WATER TANKERS, FITTINGS AND OTHER ACCESSORIES” to read: “ii. Capacity: b. Five (5) x 1,200 – 1,600 US Gallons Tanks.”

Query #2: Regarding the 5000 USG water tanker, the specifications in the BDS has asked for a tandem rear axle. Our Manufacturer has advised that a tank of this size would not normally require a tandem rear axle and that is an overspecification. They are advising that it should come with a single axle, and this would give significant cost reduction on the unit. Therefore, can we get some clarification on this requirement and advise if it would be more prudent to tender on a unit with a single axle?

Answer #2: Regarding the 5,000 USG water tanker; the preferred specification is the tandem rear axle as specified in the Bidding Documents. Any alternative offer may be disqualified.

Query #3: Will the tanks be mounted to the truck chassis or will the tanks be a pull behind trailer type? (the spec calls it out both ways).

Answer #3: i. The five (5) x 1,200 – 1,600 US Gallons Tanks will be mounted to a truck chassis. See Addendum # 1 to Bidding Documents and responses to Query #1 above.
ii. The one (1) x 5,000 US Gallons Tanks will be mounted on a Tractor with pull behind trailer.

Query #4: Do they require (2) pto driven water pumps, each producing 75gpm or can we use (1) pump that produces 150gpm? It is very difficult to install (2) pto driven water pumps on (1) truck chassis.

Answer #4: Please see Addendum #1 to Bidding Documents. We have now amended the specifications as follows:
“PART 4 – SPECIFICATIONS FOR CENTRIFUGAL PUMP” to read: “xii. Pump System: Each tank shall be fitted with either two (2) trailer / chassis mounted 75 GPM centrifugal pumps or one (1) trailer / chassis mounted 150 GPM centrifugal pump….”
