MECHANICAL INSTALLATION WORKS

ISSUES THAT THE LESSEES SHOULD PAY ATTENTION TO DURING
PROJECT AND CONSTRUCTION SITE APPLICATION

· GENERAL:

1. Before moving to each independent section, the sprinkler system must be completed in the section.

2. Sprinkler settlement project will definitely be given at the project stage. The suspended ceiling coordination plan will be overlaid on the architectural layout plan.

3. Before the sprinklers are installed, the project will be prepared according to the following principles and will be implemented after obtaining the approval of D-Structural control engineers.

a) Fire extinguishing lines inside the workplace have been established on the basis of zoning. Lines are interconnected in certain regions and are opened and closed from a single valve. For this reason, the Workplaces that will make the renovation will apply to the Technical Control Firm and will be able to make the changes within the days or time zones determined by the Technical Control Firm.

b) The activation temperatures and brand of sprinkler heads in the workplaces will be the same as the models used and approved in the building.

c) For office areas, a sprinkler system will be designed considering the light hazard class according to NFPA 13.

d) An upright or pendent sprinkler head shall be placed to protect a maximum area of 21 m2 for the Light Hazard class and the distances between the sprinkler heads shall be at least 1.8m, at most 4.6m and at most 273 m from the wall. The distance of the sprinkler heads from the wall should be at most half the distance between the two sprinkler heads in the direction in which they are placed.

e) Since there is no 1 m high parapet on the facade of the building, frequent sprinkler head layout shall be made at a maximum of 1.5 m from the facade along the facade as shown in the sample project given for each section and the distance between them shall not exceed 2 m.

f) The heads to be provided by opening the sprinkler nozzle at approximately 68C or 74C depending on the temperature of the burning environment will be selected if the water exits the sprinkler pipe nozzle. The heads shall be quick response, K factor metric 80, UL exponential FM approved. When there are locations whose temperature may be more than 40 C, it will be reported and the heads that explode at higher temperatures will be used.

g) Semi-recessed types will be used under suspended ceilings, pendent type or upright types will be used in places without suspended ceilings and in suspended ceilings. If the suspended ceiling height is over 80 cm, sprinkler head will be placed both inside the suspended ceiling and under the suspended ceiling.

h) The heads shall be in the most suitable place to drain the water to the widest area

over the partitions and flooring obstacles of the ceiling construction and to detect a fire in the fastest way.

i) The existing ceiling will be used in the placement of the pipes and the hanger will be firmly connected to the concrete blocks of the structure. The elements shall be designed and applied in such a way as not to damage the static structure and division of the building. The diameter of the pipes to which the heads will be attached shall be at least 1”.

j) In case of placement under both suspended ceiling and suspended ceiling in sprinkler system piping, the system shall be designed using the relevant diameter table in determining pipe diameters.

k) In order for the heads to extinguish effectively, the distance from the beams and channels shall be calculated on the basis of the beam or channel height and the distance of the sprinkler head from the beam or channel bottom level. Distances are given in the table below.
