DMCI Homes Balcony Railing Height • 1.10 – 1.20 meters Elevators • Medium rise buildings – 800 kilogram capacity (8 – 10 persons) • High rise buildings – 1350 kilogram capacity (18-20 persons) • Traffic analysis – used to determine the proper specifications for the elevators to be installed in the building • Zoning – Used to increase response of elevator by providing express zones for higher units. DMCI Homes Fire Exits • All buildings have provision for fire exits • Mid rise buildings – open stair exits • Single Row – fire escape ladder • High rise buildings – enclosed fire exits DMCI Homes Generator System • Medium rise projects – generator serves the water tank, pumps, the clubhouse, the hallway lighting and the elevator (no back up power for the units) • High rise projects – generator serves the same areas as with the mid rise projects, but also provide back up power of 500 watts for the units of old projects and 100% back-up power for new projects. Sanitary & Storm Drainage • Sewage water is always treated in the STP • Rain water is collected in the storm drains which is disposed of to the main lines where the project is located Flood Control • Sump pits collect rain water • Factor of safety is also considered – catchment areas are “oversized” for good measure • 3 meters – standard elevation height of DMCI Homes projects from road/street level Garbage Disposal • Mid rise projects – designated garbage areas are assigned where the unit owners can discard their garbage • High rise projects – garbage collection is done door-to-door • Garbage holding rooms keep the garbage collected by PMO • Wet and dry garbage is segregated; wet garbage is contained in a tiled room with air conditioning Storm Drainage System Under Ground Site Storm Drainage Above Ground • Perforated • Street Inlet • Dome type drains Pipes • Area Drains • Down spouts and • Sump Pumps • Drainage Collectors Manholes • RC Pipes Water Supply System Sources: Water Distribution System • Manila Water for the • High Rise: Cistern, Transfer East Side Pump, Overhead Tank, Booster • Maynilad for the West Pumps, Down feeds, Pressure Side Reducing Valves, Distribution to units. • Mid Rise: Elevated Water Tank, CPS, Distribution to units.

(NSCP) • The NSCP has strict regulations based on a 7.2 magnitude earthquake • Our projects can resist a magnitude 7-8 earthquake • Buildings are designed to “move” (deflection) Earthquake Q&A by Engr. Brian Tan • Can earthquakes be predicted? No, we cannot predict when an earthquake will occur. However, if we know where faults are located then we can say where an earthquake may occur. Earthquake Q&A • What is the intensity of an earthquake? Intensity is a description of the effect of an earthquake in a particular location. It depends on: 1. Magnitude 2. Epicenter 3. Focus 4. Soil condition Earthquake Q&A • What is the magnitude of an earthquake? The amount of seismic energy released during an earthquake • What is the difference between ‘magnitude’ and ‘intensity’? Magnitude tells you how strong an earthquake was while intensity tells you how strong the earthquake was felt in your location. Earthquake Q&A • Is there a maximum magnitude for an earthquake? Magnitude depends on the length of a fault, the longer the rupture length, the higher the magnitude. • Are buildings in Manila designed for an earthquake? If the building is designed in accordance with the NSCP, then the building can resist earthquakes. • Is it true that the West Valley Fault (WVF) can generate magnitude 9 earthquakes? No, the WVF is fairly short and the maximum magnitude it is estimated to produce based on its lengths ranges from 6.5 to 7.2 magnitude.
