2. Could you send a photographic record of the project site where the state of the facilities can be identified?

A/ Yes

3. Within the submitted schemes, could you send estimated dimensions

A/ Autocad plan sent.

4. Is it possible to change the specifications of pumps and equipment indicated in the SOW? The above due to the specified they work for aviation fuel, which is denser and requires work with higher flow rates.

R/ The pumps and equipment are required for diesel fuel or ACPM and these elements are according to the hydraulic and mechanical design presented by the bidders.

5. Do electrical installations require a RETIE certification procedure?

A/ no, only statement of compliance signed by electrical professional

10. The technical specifications of the project say that the operating flow of the filtration and pumping systems 100 GPM (1.1, 5.16.8 and 5.16.10 of the SOW) for diesel supply equipment is a flow too large, for this type of installations a maximum of 12GPM is recommended; this detail will reduce significantly the pipe diameter of the system. Evaluate the proposed change. Evaluate the proposed change.

A/ The flow of the filtration system is according to the design presented by the contractor, which will also determine the diameter of pipes and elements necessary for its correct operation.

11. The SOW in 5.16.9 section, says that the project requires the installation of a filter coalescer and separator that meets the specifications of the EI 1581 standard, these filters are used exclusively for aviation fuel systems. Review if it is appropriate to install this filter.

14. Is there a preliminary canopy structural design required for the vehicle fill island?

A/ no need to build this structure already exists

15. Is there a soil study?

A/ it does not have this

16. Is there any specific requirement for the control, communication, automation, and telemetry of the station, is there an internet facility at the location?

A/ The implemented System must control the functioning and operation of the equipment. It must allow systems to be programmed and measurements taken. The facilities have an internet system.

17. Is there a current detailed single-line plan of the location, detailing the reserve power capacity for the installation of the new equipment?

A/ It does not have this plan.

18. Should low voltage distribution board and transformer be considered?

A/ Only one control panel needs to be installed for the new system.

19. What is the current voltage of the station?

A/ The voltage is 220/110 V

20. Is there a ground mesh, what is its designed capacity, can it be used?

A/ There is a grounding mesh but the capacity of this is unknown

21. What electrical equipment should be considered and which are supplied by the contractor?

R/ All the electrical system corresponding to the fuel system, including control panels, grounding and shielding.

22. Is there a one-line diagram of current lighting circuits?

R/ It does not have a diagram

23. Is the solar panel backup system designed for what use and what capacity?

R/ There are not a solar panel backup

24. What requirements are there for jobs during the health contingency is there a salary table for the area?

A/ The requirements for the contingency are in accordance with those decreed by the national government and there is no salary table.

25. Should the Contractor Personnel that will participate in the Project stay in camp in the base area or can they move to the nearest populated area?

A/ In the place where the works will be carried out, you cannot build a camp, you must look in the urban area.

26. General payment conditions?

A/ Payments will be 30 days after each work cut

27. Is a final disposal certificate required for the final disposal of materials and equipment to be removed?

A/ It is necessary to comply with all the environmental and final disposal certificates required by the Colombian government

28. Is there basic engineering study?

R/ It is published with the pre-solicitation

29. Is there a mechanical pre-design and list of materials, where pipe dimensions and its layout are defined?

A/ no, materials and equipment are based on the designs submitted by the contractor
