| CNP Eradication Base Solicitation # 19-AQMM-18-R-0048 Q&A's | ||||
| # | Reference | Subject | Question | Response |
| 1 | I would like to request the AutoCAD Version of the drawings for solicitation 19-AQMM-18-R-0048 located in the city of Caucasia. | CDs of the AutoCAD Drawings will be available during the Pre-Proposal conference on 27 February 2018. | ||
| 2 | Can a visit to the Finca Paraguay in Caucasia, Antioquia be held on a different date, before the deadline for proposal submission of March 22nd? | Unfortunately only one site visit was available on February 27, 2018. Please know that you are welcome to submit a proposal in response this solicitation. | ||
| 3 | The Electrical Drawings of the project ask for an UPS of 15 KVA. However, the specifications of the project require an UPS of 10KVA. Please provide clarification on which UPS is required. | Follow the size of the UPS shown in the drawings, the specification is for UPS 10KVA and UP this includes the 15KVA one in the drawings. | ||
| 4 | Please confirm the connection point of the fiber optic: it will be connected to the existing rack located in the technical room of the existing CEFOP? | Fiber Optic shall be routed to the location designated by the Local ISP provider. | ||
| 5 | Please confirm whether the concrete slab level of the buildings that are to be constructed shall be the same level as the existing adjacent CEFOP. If so, the average required backfill 2.00m height (according to some measurements at the site visit), taking into account the actual terrain level, must be included in the proposal? | The levels of the existing CEFOP Building and the projected buildings are not the same. The offerors shall take into account an average height of 1.40 m for the backfilling of the projected buildings. | ||
| 6 | Regarding the concrete storm drain channel, please provide details for its construction: |
a. Height
b. Width
c. Will have some kind of grill?
d. Could be prefabricated? a. Height = 15 cm
b. Width = 35 cm
c. Will have some kind of grill?. No
d. Could be prefabricated? No, this is not required.
| 7 | The materials that are provided in the technical sheets are the materials to be used in the work or can there be changes in the course of the execution of the project? I mean changes that you can make. | Offerors shall consider in their proposal the materials that they plan to provide for the construction project based on the technical specifications that are part of the solicitation technical package. |
| 8 | Can we change or manipulate the bidding chart ?, since in some spaces the sums and totals are incorrectly formulated. | For the bid chart, the priority is that the offerors focus on using the same items that are shown on the chart. |
| 9 | All electrical and hydraulic installations must go inside the walls? or can they go external to the wall respecting the norms and materials for its realization? | All Electrical and hydraulic installation shall be embedded in the walls. |
| 10 | The coupling connection to existing servers and electrical cabinets will be done by us or are the tips left? | Contractor must provide a fully functional system under the Turn Key contract. |
| 11 | How is it required to contain the filling and leveling material?, taking into account that during the visit it was discovered that the difference in height between the waste collection box and the lowest constructed part of the project is more than 1, 20 ml, I mean if a containment wall should be made for this purpose in the perimeter of the project or if a filling without containment should be made. | As mentioned during the site visit, the offerors shall consider earth embankments with a slope that is sufficient to contain this filling. No containment wall shall be considered at this point. |
| 12 | For the movement of the containers, Who is going to make the movement of these? Who is going to demolish the existing bases? and who is going to build the new bases in the final site where these containers must be moved? Is there any crane in the base that can be used or quoted with external machinery? | The movement of the containers as well as removing the existing concrete bases, are not part of the scope of this project. A decision was made after the site visit not to add this work to this trequirement. |
| 13 | Please confirm if the rainwater drains down the sides of the project or should we connect them to a collection system? | The Storm drainage waters shall drain towards the surrounding terrain as shown in drawings SA2, SA3 and SA4 of the original solicitation technical package. |
| 14 | Could you confirm the exact location of the project in blueprints? since in the visit does not coincide the location of the structures in the drawing with what is in the area to intervene. | The offeror shall refer to drawing A01 of the original solicitation technical package for the location of the projected buildings. |
| 15 | The two types of concrete blocks that will be used in the project must be smooth or rough. | The offeror shall consider the standard Concrete Masonry Unit (CMU) with smooth finishing. |
| 16 | The finishing of the walls with graniplast is only for the exterior? or also interior? It is not well defined in the drawings. | The Graniplast finishing texture shall only be considered for exterior areas. For the Interior finishing, plaster and painting with two coats shall be considered. |
| 17 | Could you tell us in which windows the concrete sill will be built? since in no drawing it appears referenced and if we take into account that many of the windows are on the edge of the union between internal and external walls, the additional 15 cm on each side of the window that have this structure would affect the superposition of the concrete block . | The offeror shall not consider concrete sill for the windows. Only the exterior façade windows shall have sills in aluminum, but not the Interiors windows. |
| 18 | In the architectural drawings appear some levels that do not match the side view or architectural cuts of the same drawing, some descend more than 70 cm between areas of the same building, it must be assumed that the sidewalk and the central corridor are on the same level and that the rooms and offices are 10 cm above? | Refer to the Amendments of the solicitation process. Drawing A01.A was included to the solicitation technical package clarifying these levels. |
| 19 | For reinforcement of the walls should be cited as indicated in the detail provided? I ask this since in our experience the location of the rods should be 2 rods of 1/4 "in the horizontal and 1 rod of 3/8" in the vertical, since the 2 rods of 3/8 "that are located horizontally every 3 rows would give the same thickness of the mortar, leaving the bar almost bare and the vertical reinforcement in a 1/4 "bar does not provide the strength for this type of reinforcement. | Refer to the Amendments of the solicitation process. A new version of the Structural Drawings was included to the solicitation technical package. The offeror shall comply with these drawings to submit their proposal. |
| 20 | Could you give us a picture of the constructive / structural details of the skylight? something that could guide us more for what you request. | Black & Gray = Box in platen 1/4-inch thicknees. Welded to perlins and anchored to the wall with screws screws with expansion shafts |
Red = Platen 2-inch x 1/4-inch welded to platen box in "L" shape to support iron angle.
Cyan = Iron angle 2-inch x 1/4-inch to support glass. Welded to platen reds.
Blue = Tempered laminated glass 8 mm thicknees blue color
| 21 | In drawing A03, the skylight on the left side of the corridor in the top view drawing does not match the location of the side view drawing. Which of the two locations should we assume? | Refer to the Amendments of the solicitation process. Drawing A03.A was modified and included to the solicitation technical package clarifying this issue. |
| 22 | In drawing S05, the detail "typical belt section" indicates that it should be made in the anchor plate of the purlings to the beam 4 holes for 1/2 "screws, I ask, can you reduce the number of holes or reduce the diameter of the screws? since if you take into account that the beam only has a section of 20 x 15 and ii is reinforced with 1/2 "rods and 3/8" strips every 20 cm the remaining space is too much small for the exact location of that number of holes or screws that will be placed. | Refer to the Amendments of the solicitation process. A new version of the Structural Drawings was included to the solicitation technical package. The offeror shall comply with these drawings to submit their proposal. |
| 23 | Taking into account the previous point, I take the audacity to make the following suggestion, would it not be more viable to make a steel structure for the roof anchored to the concrete beam that is + 2.80mt by means of voussoirs, purlins and welds? | Refer to the Amendments of the solicitation process. A new version of the Structural Drawings was included to the solicitation technical package. The offeror shall comply with these drawings to submit their proposal. |
| 24 | Please confirm if the cross section of the cyclopean concrete required in the structural drawings of the Project corresponds to 0.40*0.90m. if the answer is no, please provide the correct cross sectional measurement for this activity | Refer to drawing S-01 of the original technical package which shows the typical cross section of the foundation, as well as the cross section of the cyclopean concrete. |
| 25 | Please confirm if the existing containers located in the area of the project will be removed by the CNP or if this activity must be included as part of this contract. If will be removed by the CNP, demolition of concrete footings of these containers must be included as part of this contract? | Refer to answer to Q12. |
| 26 | The air conditioning activity requires a multi inverter system with distribution boxes or BD (Branch distribution) units. However, these BD units are not commercialized in Colombia. They would need to be imported, which would highly elevate the cost of this activity. Then, should the initial design remain as it is with the BD units? Or can it be done with only copper piping instead as usual in this kind of installations in Colombia? | See note on drawing M05. BD units shall be proposed by the contractor as necessary. |
| 27 | The structural drawings of the Project require electro welded mesh of 10mm diameter for the reinforcement of the concrete slab. However, this diameter is not available in Colombia. Please provide information on which electro welded mesh shall be used instead or if the requirement remains the same, and is necessary to “build” the mesh on site using 3/8” steel bars? | Refer to the Amendments of the solicitation process. A new version of the Structural Drawings was included to the solicitation technical package. The offeror shall comply with these drawings to submit their proposal. |
