# Questions Answers

#1 Is it possible that you can provide us the Soil Study carried out for the project design, in order to know the water table at the construction site, in order to make an adequate work schedule and budget for the work?

R/ Please see attached.

#2 To obtain the construction permit from the municipality, the amount corresponding to the work risk policy must be paid in advance. Should this payment be made and contemplated within the value of the work? Or must the declaration of the contract be made before the INS?

#7 In Draws 02 Site_ESTRUCTURAL.pdf, in RAMP SLAB DETAIL BE3 indicates 30cm thick granular sub-grade CBR 30 min plus T=15cm GRANULAR GRAVEL CBR= 70MIN, it is possible to replace these 2 layers of 50 cm fill with 2 gabion mats in hexagonal mesh with plasticized wire type 6x8 of 60cm thickness or 50cm gabion with gabion stone? This is because the proposed base and sub-base, when submerged twice during the day, will lose all compaction, which is why a material must be used that does not soften due to the effect of water and is also confined by the coated steel mesh. with pvc that allows it to maintain the necessary geometry for the ramp, also from the point of view of workability, the project is more efficient and will guarantee the structural capacity that is required.
