DESIGN STATEMENT

THE MILLENIUM SCHOOL CONTEST,FIRST PLACE WINNER

The first glance starts with the analysis of structure, its material used and its stability; from the slope of the roof to the details of foundation. The roof provided, in two modules with high-level opening along with angles of 30 and 35 degrees to the horizontal is a leading step to minimize the wind pressure, which is a dominating factor of disaster. The base slab provided of reinforced concrete with a definite uplift is an all time solution to minimize disaster of flooding. The seismic activities also holds effective disastrous effects in Philippines. The use of pile foundation is an very common and to the extent, successful engineering step to hold the structure during earthquake. Along with covering the disaster factors, The design is also made to ease the after disaster effects. An example lies is the use of Double post which is a leading step to ease the repair works. Concisely stating, the design is made after detailed study and analysis of every sphere of influence of the construction area. Though the structure may not be able to resist extreme super typhoon conditions, yet it is one of the best engineered and designed bamboo material structure.

SITE STRATEGY

ORIENTATION AND SITE SELECTION The class module structure is settled in such a way that the front view faces the west. Thus the setting rays of the sun, falls on front and the rising rays of the sun falls on back. The Structure is more prone to direct sunlight than indirect sunlight. The orientation is well decided; studying and observing the lightning conditions during and day and evening. The overall all site strategy is oriented in north-south direction, with car parking and main entrance facing the north. A lobby throughout and across every set of classes is provided for general pedestrian movement. The structure is preferred over softscape than hardscape. The structure mainly stands over raw material The structure over softscape, will bring an ease to repairs after disaster effects. The hardscape is more preferred when structure mostly uses the present day building material rather than green building material.

CIRCULATION

VEHICULAR AND PEDISTRIAN The vehicular circulation is barded at the entrance of School. A clear parking space is provided for vehicles to park. The pedestrian circulation is kept in flow inside of school. A general lobby is provided for easy flow along and across each pair of classes.

DIRECT/INDIRECT CIRCULATION The Structure is more under influence of direct circulation rather than indirect circulation. One of the reason lies is the proper orientation strategy and more use of raw material.

INSIDE/OUTSIDE CONNECTIONS The structure is designed in a very good airflow way. The air easily circulates and passes by the structure. Special considerations are done to prevent the structure from being an obstacle to the airflow and to distribute the air pressure in proper way. This minimizes the damage on occurrence of disaster.

PUBLIC/PRIVATE ZONES The structure is a school. Thus the location zone is adopted to be public and safe yet peaceful.

STRUCTURE AND ENCLOSURE BUILDING ASSEMBLY SYSTEMS

The structure roofing is done with cross-braced and battern lashing format. The use of bamboo with double posts provides better holding and also an ease of repair during damage. The roofing arrangement with metal sheets, nailed to bolters is quite of a used technique, a good protection against wind pressure. Also double safety being provided to hold these sheets by settlement of bamboo poles with smaller diameter using pins and lashes.

STRUCTURE STRATEGY The structure is basically laid over reinforced concrete frame. This reinforced concrete frame is held over by pile foundation. The roofing is done by light material bamboos and covered by metal sheets. The pressure is distributed by steeled patterns of bamboo decided after study and analysis. The direct load is resisted by reinforced frame.

FENESTRATION

The windows made of bamboo material , framed in concrete allows the easy flow of air and light. The orientation helps and ample of light is available in classes during morning time. The gap provided between two classes in a pair allows easy movement of air. The gaps provided between every pair of classes also decrease the wind pressure.

LIGHTNING

ARTIFICIAL/NATURAL LIGHTNING The design of school is in such a way that the area is more prone to natural lightning and artificial lightning required mostly only during night time. The panels provided in the classrooms act as natural lightning source. The sun rises with the light first approaching the classes ;thus fulfilling the light needs.

SEQUENCE OF LIGHT TO DARK/ATMOSPHERIC EFFECTS Since the structure is mostly made by raw material.. i.e. bamboo ,thus it is environmental friendly. The material as such does not traps heat. The atmosphere inside is good and affordable for students and teachers. Under different normal atmospheric conditions, the material is sustainable.

DIRECT/INDIRECT The school is more prone to direct light. Due to the property of material, partially indirect light is also provided.
