3B. Security and Protection of Equipment 

The vendor shall ensure the safety and security of the motor pump, solar panels, charge  controller, battery, and all cables and connectors, both during execution and on handover. This  shall include, as applicable: 

• Secure mounting of solar panels on a hot-dip GI frame, firmly anchored to the RCC roof to resist wind  loads and deter theft. 

• Protective enclosure or lockable housing for the battery, charge controller and inverter, installed on a  fabricated iron stand in a safe and ventilated position. 

• All cables and connectors properly routed in conduits, secured, weatherproofed, and protected against  mechanical damage, rodents and water ingress. 

• Earthing/grounding and appropriate protection devices for the electrical system as required for safe  operation. 

• Safe and secure installation of the motor pump with proper alignment, protection from water ingress  and unauthorized access. 

4. Pricing Requirements 

4.1 Pump Type (rates required for both options) 

The expected bore depth at all three target villages is between 60 and 70 feet. As advised by the  donor, the pump type (surface or submersible) is to be confirmed on the basis of what is commonly  feasible in the area and the actual ground conditions encountered. Vendors must therefore quote  separate unit rates for both pump types, each rated 0.75 HP. The applicable pump for each station  will be selected by the organization in consultation with the Engineer, and payment will be made  against the pump actually installed.

4.2 Borehole Water Testing and Re-Drilling 

As required by the donor, a water sample must be taken from each freshly dug borehole and  tested for drinking-water quality. If the water from a bore is found unfit for drinking, the vendor  shall drill an additional bore at an alternate point, and this process shall continue until a bore  yielding water fit for drinking is obtained. Because the exact depth of each bore is not known until  drilling is carried out, vendors must quote a rate per running foot (Rft) of drilling. Every bore drilled,  including any additional bore required after a failed water test, will be paid at this same per 

running-foot rate against the actual depth drilled, subject to verification. 

Note: The per-running-foot rate must be all-inclusive (drilling, casing, strainer, suction pipe, and water  sampling). Payment for drilling will be made against the actual footage drilled at each station, including any  additional bores reasonably required to reach potable water, subject to verification by the organization and the  donor’s technical team. 

5. Completion Period 

The completion period must not exceed three (03) months from the date of the work order. This  is an outer limit only, not an expected or preferred timeline: quotations proposing a completion  period longer than three months may be rejected as non-responsive. Vendors are expected to  compete on the shortest realistic completion period they can commit to, which is scored favorably  during evaluation (see Annexure C). Vendors must clearly state their proposed completion period  in their quotation. 

6. Eligibility Criteria 

To qualify, the bidding firm must meet all of the following minimum requirements: • Be a firm/company duly registered with the relevant government authority. • Possess a valid National Tax Number (NTN). 

• Have demonstrable experience in executing similar solar water supply and/or  construction projects. 

• Have sound financial standing sufficient to undertake works of this nature and value. 

Quotations from firms that do not meet these criteria, or that fail to provide the supporting evidence  listed in Section 8, may be rejected as non-responsive. 

7. Evaluation Method 

Quotations will be assessed on a quality-cum-cost basis. The evaluation will consider, in  combination, the responsiveness and technical compliance of the offer, the firm's relevant 

experience and capacity, the proposed completion period (shorter realistic periods preferred), and  the quoted price. The contract will be awarded to the firm offering the best overall value to the  organization and the donor, not necessarily the lowest price. 

The organization has not disclosed a budget estimate. Vendors are required to quote their own  competitive, all-inclusive rates against the BoQ. 

8. Required Submission Documents 

The sealed quotation must contain the following documents. Incomplete submissions may be  treated as non-responsive. 

9. Submission Instructions 

• Quotations must be submitted in a sealed envelope clearly marked: “Quotation – Solar  Water Stations – Do Not Open Before Deadline.”

Annexure C — Evaluation and Selection Criteria 

Quotations will be evaluated on a quality-cum-cost basis using the 100-point matrix below, split  80 points financial and 20 points technical. There is no minimum technical threshold; all  responsive quotations are scored in full. The quotation with the highest total score will be  recommended for award. 

Scoring Matrix 

Notes on Scoring 

• Standardized price basis: for scoring, every bidder is assumed to require the surface motor pump (Part  II-a) and one bore per station drilled to a standardized depth of 70 running feet (bore rate x 70 Rft).  This same basis is applied identically to all bidders. Actual payment follows the actual footage drilled  and the pump type actually installed; neither affects the score. 

• Price: computed as the indicative grand total on the standardized basis. The lowest compliant grand  total receives the full 65 points; others are scored in proportion. 

• Completion time: the shortest realistic offered period receives the full 10 points; others in proportion.  Implausibly short periods may be treated as non-credible. 

• Validity: the highest validity offered receives the full 5 points; others in proportion. Minimum acceptable  validity is 60 days. 

• Experience, turnover and technical capacity are scored from the information and evidence provided in  Annexure B. 

The organization reserves the right to reject any or all quotations without assigning a reason, to  seek clarifications, and to verify any information or document submitted.
