Mechanical ventilation Mechanical ventilation (i) Fan capacity and to also indicate duty and standby fans. (ii) Extract points (iii) Replacement air doors/windows/vents and their sizes/areas (m 2 ). (iv) Demarcation of smoke zones. (b) Fire protection Fire protection (i) Sprinkler/Water monitor coverage, etc (ii) Sprinkler details (Discharge rate, Response Time Index, etc)

42 5.4 Reference Drawings for FEDB & FER Submissions Reference drawings are to be submitted at the FEDB and FER stages. These drawings should capture all alternative solutions and fire safety provisions that support the performance based design. It should also capture all the elements of the FSE’s trial design concept in their alternative design. Reference drawings would be used by SCDF when deliberating on the performance based fire safety issues for FEDB and FER approval. Reference Drawings for FEDB & FER Submissions 5.5 Unlike the drawings for the formal building plan/M&E plan submission, the reference drawings need not be broken up into the architectural and M&E sets. However, the reference set must include all performance based floors and relevant elevations/sections. Items to be marked up on the reference plans include (but not limited to): (a) Details of all alternative solutions (alternative solutions are to be numbered). (b) Design fires. To mark up location and fire size. All design fires to be numbered. The reference drawings should also include sensitivity studies. (c) Floor height/s (d) Fire shutters and smoke curtains (e) Compartment walls/boundaries, including fire resistance rating. (f) Occupant Loading and Egress Capacity (g) If they are alternative solutions and form part of the performance based design solution, the reference drawings should show : (i) How reservoir length/area is measured. (ii) Paths of extended travel distance

43 (iii) Paths of extended travel distance for internal discharge (h) Mechanical ventilation fans and ductwork. To indicate how many duty fans operate during fire emergency and how many standby fans are there. (i) Differentiate separate smoke control zones (j) Smoke control matrix (k) Path(s) of replacement air. To also show openings on the elevation. (l) Path(s) for natural smoke exhaust. To also show openings on the elevation. (m) Sprinkler details (E.g. : temperature rating / RTI / Discharge density) (n) Beam detector location, if any 5.6 For drawings to be submitted at the Building Plan approval stage (together with the FER, Peer Reviewer Report & O&M Manual) the submission could contain both (1) the formal BP/M&E set of drawings for approval and the (2) set of reference drawings. The design team may choose to combine both sets into a single set of drawings that would be used for approval and presentation/deliberation by SCDF. Reference drawings must be endorsed by the FSE.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
