Architecture A-NP-102 In areas where walls will be removed and floors will be left bare, will we have to remove complete pieces of flooring and replace them in order to follow the same format?

It must be ensured that during the demolition process, damage to the floor pieces is minimized, with the objective of avoiding the complete removal of the tiles. In cases where the damage is significant and it is not possible to repair the affected pieces in situ, it will be necessary to install a new tile as specified in the finish schedule.

Structure General During a visit, a contractor realized that the beam to support the truss that is attached to the building is on the internal axis of the building and not on the side where we are going to work on the truss. They commented that they would send a detail for this connection.

For more details on what to assume refer to SF Reply to RFI 051. Also Refer to the existing structures plans shared on the reply to RFI 050, Detail 2B of the file "1993 Library Roof 3" from the Tupper Library expansion, if was executed as the detail recall the exisitng trust shall be accesible form the side where the work will be excecuted.

Structure

We were unable to obtain the detail of the connection of the new structure with the existing one on axis 8

Details DC-C S507 should apply. It is important to note that Truss type "A" from existing condition drawings is concealed in the exisiting wall, thus exact details of this truss as it has been built are not available. During demolition, the condition of Truss "A" should be evaluated and analyze if this shall be kept and truss CH-8 is built beside, or replaced by CH-8. However, if additional information is needed at the time of execution, this will be provided by the A/E.

Architecture A-NP-102 Can you better specify what you mean by patched concrete on the floors? a finish exactly?

By "patched concrete," we are not referring to a specific finish. The existing floor is covered with vinyl, which must first be removed. Next, any cracks in the concrete should be repaired using an appropriate filler or additive (by this repais we are referring to patch concrete). Finally, the concrete must be polished to achieve a smooth surface.

Architecture A-CP-105

In these areas we see that there is no sky marking, is this an error in the plan?

It isn't a draft error, in those parts indicated, there's no ceiling because the roof in those spaces has a different shape. For further clarification, please refer to drawings A-DT-502, DT1, and DT2.

Architecture A-CP-105 Above the slatted ceiling, should the ceiling structure be painted?

Yes, the structure above the ceiling should be painted (refer to spec 09 00 00). However, the contractor must propose the painting system based on the manufacturer’s recommendations. The manufacturer will specify the necessary substrate preparation. In principle, it should be the same system used for the new trusses. Typically, this involves SSPC-SP3, depending on the type of paint used. Additionally, the structure below the ceiling must be repaired and painted if any damage occurs during construction (refer to the demolition note).

DWG F-DT-503 (Pag 49/65) 21 13 13 Wet-pipe sprinklers systems

Notes in drawing F-DT-503 says design is based in NFPA 13 2012 but specs 211313 WET-PIPE SPRINKLER SYSTEMS in say NFPA 13 2019. Has the drawings notes more precedence than the specs?

The specification continues as a guide, the project will be governed by the NFPA-2019 regulations.

Fire Suppression Spec 21 13 13 Wet-pipe sprinkler systems, 1.07

Specs 211313 WET-PIPE SPRINKLER SYSTEMS in 1.07 says that the sprinklers heads has to be align with the reflected ceiling and all ceiling-mounted equipment, such as diffusers, lights, security cameras, fire alarm systems, exit signs and other items but we are not the designers. Can you confirm if the designers take into account all these requirements in the design of the fire sprinkler systems?

In the annex area, the sprinklers will be installed 20 cm below the ceiling, while the pipes will be level with the top of the slab. This arrangement ensures there will be no interference with other elements, as the pendant lights hang 10 cm from the ceiling, allowing the pipes to be positioned above them and the sprinklers to be at a lower level. In the rest of the library, the sprinklers will be flush with the ceiling.

We are also considering that trusses will cause interference in some areas.,this interference has been anticipated and is permitted according to norm 10.2.7.1.6 and 10.2.7.2.1.7 from NFP-13_2019.

However, we have identified two lineas of sprinkles that during construction must be relocated 30cm away from the location indicated in the drawings to avoid interference according to the norm. If a detailed plan with this adjustments is required it will be provided once the contractor is selected.

Fire Suppression Spec 21 13 13 Wet-pipe sprinkler systems, 2.03.C.1

Specs 211313 WET-PIPE SPRINKLER SYSTEMS 2.03.C.1 says a wet pipe system shall be provided with a listed relief valve not less than 1/2" set to operate at 175psi or 10 psi in excess of the maximum system pressure, whichever is greater, but in the drawings there are no indication in what place to put this. Please confirm: are we have to include a relief valve in the riser manifold or any other place in the sprinkler system? If the answer is yes, please mark or indicate the place to be installed.

The system pressure is below 175 psi, however the relief valve must be considered in the zone control, as planned for the future
