7. ¿Cuál fue la fecha del arranque inicial de estas unidades?. ¿Están aún en garantía? (What is the commissioning date of each one? Are they still under Warranty?)

8. ¿La propuesta a ser entregada es por los servicios descritos en el artículo 4.1?. Esta pregunta surge debido a que en varios puntos del Addendum SF-1449 menciona la palabra “reparaciones”, pero en el detalle del artículo 4.1 sólo incluye labores de mantenimiento, no de reparación. ¿A qué se refieren con “reparaciones”?. (Is this proposal only for the services mentioned on the article 4.1? This question comes out do to several points in the Addendum SF-1449, where mentions the word ¨reparations¨, but in the detail of the article 4.1 it only includes labors of maintenance, not reparations. What do you refer with the word ¨reparations¨?)

It is intended that the Contractor will provide routine maintenance on the schedule outlined in the contract solicitation. If, during the routine maintenance the Contractor discovers that a minor repair/replacement must be performed in order to ensure the proper functioning of the generator, this is covered by the contract. It is natural that parts will wear out over time and the Contractor will replace those parts during maintenance in order to repair the proper functioning of the generator. The objective of scheduled routine maintenance is to eliminate or minimize generator malfunction, breakdown and deterioration. Contract maintenance must ensure continuous, safe, and satisfactory operation of all generators, their parts and components.

Thus, the Contractor can minimize the need for repairs by performing effective maintenance.

What is not covered in the contract is repairs that must be performed outside of the periodic maintenance visits. Those repairs will be quoted separately.

9. Si en los chequeos de inspecciones de rutina se encuentran partes que hay que cambiar o reparaciones que se deben realizar y que no están incluidas en los puntos del artículo 4.1, ¿se cotizarán aparte? (If during the routine inspections we find parts that we have to change or reparations that we have to do and that they are not included in the points of the article 4.1, do we have to do different quotation for this? Or how we could proceed in this case?)

10. Según el Addendum SF-1449 se menciona una visita al mes, pero por el régimen de trabajo y por nuestra experiencia creemos serían necesarias más visitas al mes. ¿En nuestra propuesta final podríamos realizarla en base a más de una visita al mes? (On the Addendum SF-1449 there is mention of one visit per month, but for the way that we work and our experience we believe that it is necessary more visits per month. Could we make our final proposal based on more than one visit per month?)

Yes, offerors may make suggestions in their proposals. However, please note that all of the basic proposal requirements must also be met (Section 1, Section 3, Section 4, Section 5.)

11. Dentro de los puntos exigidos de servicios de mantenimiento anual menciona que se realizará un Full Load Test. ¿Esto debe hacerse con un banco de carga o podría hacerse con la carga de la edificación? (Among the points required of the annual Generator Maintenance Services it mentions that we will have to do a Full Load Test. Do we have to do this with a Load Bank or it could be done with the load of the compound?)

There will be a load bank in place.

12. Parte de las labores que deben realizarse están tomar muestras de aceite, coolant y combustible para su análisis. Normalmente no habría impedimento en realizar los análisis del coolant y aceite, porque el ganador de la licitación suplirá dichos fluidos, pero en el caso del combustible debería realizarlo el suplidor del combustible. ¿Está estipulado así o el ganador debe hacer el análisis? (In part the labors that we should do we have: take lube oil samples, coolant and fuel for analysis. Normally they will not be any impediment in realizing the analysis of the coolant and lube oil samples, because the winner of this bidding will supply these fluids, but in the case of the fuel sample this should be made by the Fuel Supplier. Is it stipulated to the winner to do the Fuel analysis?)

The Contractor shall perform the fuel analysis as well.

13. Según el artículo 4.1 los chequeos y mantenimientos están basados en tiempo (meses) no en horas, además que no están apegados al manual de operación y mantenimiento de Cummins.

¿Por qué el cambio?. ¿Podemos realizarlo en base a lo que recomienda el fabricante?. Favor ver archivo anexo, con las prácticas de mantenimiento recomendadas según Cummins. (On the article 4.1 the inspections and the generator maintenance service are based on time (months) not in hours, also that they are not attached to the manual of operation and maintenance of Cummins. Why this change? Can we do this in based on what manufacturer recommends?)

Please look at the attachment of this email, with the maintenance schedule according to Cummins.)

Per the contract solicitation, “The Contractor shall provide a trained mechanic to inspect and service every generator and related peripheral equipment once a month, every month of the year to maintain the equipment to manufacturer’s specifications. Following the manufacturer’s recommendations, the Contractor shall also perform more involved maintenance at different intervals.”

14. Una de las exigencias de la licitación es que los materiales deben tener 12 meses de garantía .La garantía de los Repuestos Cummins es de 1 año, exceptuando Correas, tuberías y mangueras (que tienen 1 año o 500 horas de trabajo, lo que ocurra primero). La garantía de Fleetguard (Cummins Filtration) varía según el producto adquirido. Favor ver anexo políticas de garantía de Cummins y de Fleetguard. ¿Podríamos basarnos en la garantía que dan los fabricantes? (One of the requirements of this bidding is that the materials should have 12 months of warranty. The warranty of the Cummins parts is of one year, except for belts, pipes and hoses (they have one year or 500 working hours, whichever occurs first). The warranty of Fleetguard (Cummins Filtration) depends on the product type purchased. Please look at the attachment with the warranty coverage of Cummins and Fleetguard. Could we base us on the warranty of the manufacturer?)

The Contractor may base the parts warranty on the manufacturer.
