112 Chapter V Site Development Conceptualization and Analysis This chapter gives an overview and the information gathered by the researchers about the site. It includes all the site factors and how they coexist and interact. The purpose of this analysis is to provide information about the site assets that can help the researchers in the design process. Site data The site data enable the researchers to identify the existing conditions of the site, along with any imminent or potential future conditions. Site data includes issues such as site location, size topography, zoning, traffic conditions and climate. Site data is also considered in order to identify the future developments or changes to the site surroundings, such as change of roads designations, changing cultural patterns and other significant building developments within the area. Site data allows the researchers to understand the existing opportunities or problems in the site. The suitable site for the Information Communication Technology building can be envisioned as generally level with some topographic interest, having complete utilities, stable, well drained soils, excellent road and pedestrians access, and protection from excessive weather patterns. Availability of land, land use, public and other issues can have influence on the site. The gathered data would be the basis or guide by the researcher to the design of ICT Building. 113 a) Location of the site The site is located at Eastern Visayas State University, Tacloban City. Since the location of the site is located at the university it can be accessible through Salazar St. and athletic road in order to access the site the internal roads of the university will be used. Subsequently it is located at the university, the school can be a landmark to locate the site. The existing buildings near the site are the IT building and life Building. In terms of car parking there is none existing parking in the site and only one interior road is located within the site. This Site Fig. no. 85 Location of the Site Source: www. earth.google.com 114 b) Neighborhood Context The site has nearby existing buildings the IT Building and Life Building. These buildings are used for learning and educational purposes. Since the site is located in Eastern Visayas State University the activities within the nearby buildings of the site cannot create strong vehicle or pedestrian traffic because the university has a regulation to limit the entry of vehicle within the school premises. In the site there is only one existing adjacent interior roads and there is no existing parking area. Subsequently, there is no existing historical building or buildings of particular significance. Life Building IT Building Fig. no. 86 Adjacent Buildings c) Zoning and Size Since the site is located in Eastern Visayas State University it is classified as an institutional area. The site lot has a total of 2,906.19 sqm and the boundary of the lot of the school will be the basis by the researchers. Since the site is relatively flat and slightly sloping only the flat area will be utilized as buildable area to preserve the sloping area. In order to access the site, the existing minor road and existing pathways of the university will be utilized. In terms of access to site for construction there will be no obstacles or restrictions that could 115 affect the construction process since the site has a two-way minor road and has no active traffic construction vehicle or equipment can access the site easily. Fig. no. 87 Size of the Lot d) Legal Information The site is owned by Eastern Visayas State University which is a government property. According to Physical Planning and Infrastructure Development Office (PPIDO) since the site is located in the university only building with institutional use can be built within the site and since the site has an existing old building but subjected to demolition and there is no future developments plans in the site.

Topographical Condition Tacloban City’s mean elevation in the flat portion of the city’s land formation is 3.05 meters above sea level. Since the site is located at the mountain side of Eastern Visayas State University, the site has an elevation of 33 meters above mean sea level, overlooking to downtown area. The site also has a relatively flat area and small area is sloping where trees are located. Fig. no. 89 Topographic Map Source: Tacloban City Comprehensive Land Use Map 118 2. Geological Condition According to the CLUP of Tacloban City there are four rock formation units found in the area. These are: the Quaternary Alluvium (1.6 mya to present); the Turbidite (successively layered rocks) sequence of Bagahupi Formation, which is Pliocene (0.01 to 1.6 mya) in age; the San Ricardo Formation, which is Early to Middle Miocene (11 to 23 mya) in age; and the Tacloban Ophiolite (Balce, C., 1997, pers. Comm..), which encompasses the successive sequence of Schists, Volcanic, Serpentine and Gabbroic rocks all thought to be of Cretaceous (65 to 135 mya) in age. Since the site is located at Tacloban City proper it is classified in the sedimentary sequence of San Ricardo Formation, which is very slightly dipping and rising within generally lowland area. Fig. no. 90 Geologic Map Source: Tacloban City Comprehensive Land Use Map 119 3. Climatological Condition According to the CLUP of Tacloban City climate in the city is classified by PAGASA as falling between the boundary of Type II and Type IV which indicates that there is no dry season. There is no pronounced period for maximum rainfall, which normally runs from July to December, but that rainfall is more or less evenly distributed throughout the year except on adverse periods when there is La Niña or El Niño. As demonstrated in the figure below, the month of December 2019 registered the highest rainfall with 427.8 mm. Inversely, March, the driest month of the year, registered only 29.6 mm of rainfall. Hereunder figure 91, showing the Mean Monthly Rainfall for year 2019 and January 2020. Fig. no. 91 Mean Monthly Rainfall, Tacloban City Source: www.worldweatheronline.com 120 4. Vegetation The site has an existing tree in the sloping area and small open space in the site. Since there are existing trees in the sloping area it is a great advantage because it will help to prevent soil erosion in the site and can give shading within the site. Fig. no. 92 Existing Trees in the Site f) Man-Made Features Since the site is located at Eastern Visayas State University the site was only used as an institutional area since 1907 where it become a public university and no conversion made until today. The site has an existing old buildings built within the site and not part but according to Physical Planning and Infrastructure Development Office (PPIDO) it is subject for demolition and there are no future developments within the site. 121 Fig. no. 93 Existing Building in the Site g) Circulation The site can be accessible both vehicular and pedestrian through the interior road and walkway of the university. In terms of accessibility of disabled person there is existing facilities and utilities in the university but not totally developed. Since the site is located in the university there is no heavy traffic created in the site because the university has a regulation to limit the entry of vehicle within the school premises. The travel time from the school administration to the site is approximately 5 minutes in terms of walking. In order to arrive to the university there are public transport vehicle close to the site like tricycle and multicabs. 122 h) Utilities and Facilities Electricity Source. The main source of electricity of the site is connected from LEYECO II. Another power source is generated through the school’s generator in times of power shortage. Electrical Poles Generator Room Fig. no. 95 Electrical Pole and Generator Room Water source. The source of water supply of the site is connected to LMWD (Leyte Metropolitan Water District) and comes from existing cistern of the school. Existing Cistern Water Line Fig. no. 96 Existing Cistern and Water Line 123 Internet connection. The source of the internet line is connected through SMART Telecommunication company. The server is located at the Administration building in the university and distributed the internet through LAN to every department. Fig. no. 97 Server at Administration Building Storm Drainage. Since the site is located in Eastern Visayas State University there is existing drainage system within the school that is connected to the city drainage system. Since the site is in the mountain side of the university and have none existing drainage system it can be connected to the adjacent existing drainage system of the university. Fig. no. 97 Existing Storm Drainage 124 Waste Disposal. Since the site is inside the university, the garbage waste is being maintained by the school’s utility and the university has its own Waste Disposal Facility. Fig. no. 98 EVSU Waste Disposal Parking Areas. The site has non-existing parking space and has inadequate number of spaces. Since the school has parking spaces it will be utilized. Fig. no. 99 EVSU Parking Spaces 125 i) Sensory The proposed site that the researchers have been selected consist of pleasant and unpleasant view, noise elements that came from classrooms and from the vehicles, and also unpleasant odor that made the site has negative side. In the figure below shows the pleasant and unpleasant views, noises, and also the odor that current site has. These elements were considered by the researchers in the design process for it has a great effect not only to the structure but also to the end users of it. Pleasant views include the façade of the site (overlooking view), it has natural environment like trees, right side of the entrance façade of the site in which it has trees that can be used to block intense heat from the sun, and also at the rear side of the site in which hill side with bamboos and green sceneries were the most highlighted in this area. Unpleasant views include the left and front side of the proposed site in which most of not used materials for carpentry were stocked at the area. At rear side, it has unpleasant view in which most of the shrubs were not properly maintained. Another element that the researchers have been considered is the unwanted noises that is generated by vehicle and in classrooms in Information Technology building. the researchers make used as an advantage of having trees in the site it can also be used as a noise barrier. Lastly, even the if the proposed site is located at the higher elevation of the university, problem arose in terms of unpleasant odor that comes from the garbage at the front side of the site. This can cause diseases to the end users of the proposed ICT building. 126 Fig. no. 100 Sensory Map 127 Site Hazard Maps Tacloban city is one of the most hazard prone cities when it comes to natural hazard and human-induced disasters. Since the site is located at Eastern Visayas State University the CLUP of Tacloban city will be utilized. This following maps includes Flood, Ground Shaking, Liquefaction, Rain-Induced Landslide, Storm Surge and Tsunami Hazard Maps: Flood Hazard Map The selected site is located at Brgy. 43-B, Salazar St., Tacloban City. As shown in the figure below, the indicated the site is at moderate flood susceptibility. This Site Fig. no. 101 Flood Hazard Map Source: Tacloban City Comprehensive Land Use Map 128 Ground Shaking Hazard Map As shown in the figure below, most part of the city is indicated with purple colors which corresponds to “destructive”. With the advance technology in planning, design, and even construction, the researchers consider this factor to the proposed project to secure safety to the end users This Site Fig. no. 102 Ground Shaking Hazard Map Source: Tacloban City Comprehensive Land Use Map 129 Rain-Induced Landslide Hazard Map Aa shown on the figure below, it shows the rain-induced landslide hazard map of Tacloban city. The photo highlights the site location’s position that it is classified as high landslide susceptibility. Although the site is in a brink of disadvantage. This does not stop the researcher to continue the proposal. This disadvantage, as a mountainous area means as an advantage for the Oasis ICT building. Because, ICT facilities such as the radio control and ICT infrastructure such as antennas are supposedly residing on a high-altitude area. Fig. no. 103 Rain-Induced Landslide Hazard Map Source: Tacloban City Comprehensive Land Use Map 130 Liquefaction Hazard Map The figure below shows the Liquefaction Hazard Map from Tacloban City Comprehensive Land Use. The selected site is located at Eastern Visayas State University main campus Brgy. 43-B Salazar St., Tacloban City and is indicated as not a prone to high susceptibility of the soil. Fig. no. 104 Liquefaction Hazard Map Source: Tacloban City Comprehensive Land Use Map 131 Storm Surge Map The figure below shows the Storm Surge map of Tacloban City. The selected site for the proposed project is located at Eastern Visayas State University main campus Brgy. 43-B, Salazar St., Tacloban City. A s the map has shown, the selected site is not prone to storm surge and is only 0.3m<1.0m inundation depth. Fig.no. 105 Storm Surge Map Source: Tacloban City Comprehensive Land Use Map 132 Tsunami Hazard Map . The selected site for the proposed project is located at Eastern Visayas State University main campus Brgy. 43-B, Salazar St., Tacloban City. As map has shown below, most of the areas especially in downtown are is prone to tsunami. The selected site is at the higher elevation of the campus and even of the city. Fig. no. 106 Tsunami Hazard Map Source: Tacloban City Comprehensive Land Use Map 133 Research Data Application The researchers gathered data that will be used in building design, site planning and landscape design. All data that have been gathered have a positive and negative impact on the design process for the proposed structure and for the site. The data such as wind direction and sun path will be utilized in the building orientation. The sun path served as one of the bases in order design a good and efficient ICT building that can provide aesthetics to users not just the structure itself but also its spaces. Wind direction greatly affects the structure. Considering the Northeast monsoon or the Amihan and also the Southeast Monsoon which is the Habagat. The researchers considered these wind directions for the use of passive cooling and building orientation. The site of the proposed structure has its existing components. These components such as the natural features like trees and plants will be utilized in the landscaping. Sloping terrain at the entry part of the proposed structure will be utilized as sloping landscape. Trees at the rear part of the site will be utilized as blocker from incoming wind. Existing cistern tank near the site will used as water source for the building. Existing open space in front of the sloping terrain will be utilized as parking space, guard posts and for the generator house. Also, the researchers found out that there were no street lights existing in the site. Therefore, the researchers proposed the use of street light in the site for the purpose of safety and security during night time. Trash bins will also be incorporated for proper waste segregation of the area. Though the site has positive elements such as sceneries and greeneries. The location of the site itself also has some negative impacts. These negative impacts such as in the building 134 design, the researcher will avoid excessively overhanging floor. Because the site is in a mountainous location. The site is exposed to strong wind pressure and prone to soil erosion. Site S.W.O.T Analysis This analysis is used to identify the Strengths, Weaknesses, Opportunities, and Threats that surround the design proposal. Based on the evaluation and analysis that the researchers have been conducted and collected, the site has features that comply in creating a sustainable ICT building. Strengths Location. Since the site is located inside the campus it is accessible and convenient to the user specially the students and staffs, therefore it would be an advantage for it would be convenient for the user to access the site. Physical Factors. The project site itself is a great advantage. The site has enough space for identified activities. In this aspect, this could be a strength since the proposed project is a venue for all information, communication and technology activities. Weaknesses Site is too far from the school entrance. Since it is an interior site, access for vehicles would be congestions to the school’s main access road. No service entrance for the site. In this aspect, putting up new service entrance and widening of access roads inside the campus is a solution. Parking Spaces. The site has limited space for parking spaces. In this aspect, creating proper parking flow and additional parking slot might be a possible solution. 135 Opportunities The site will help to contribute in decreasing some congested areas of the school. As the increasing number of population of student in the school, the lack of space for leisure time and students lounge is needed. Hence, this place would be a great contribution for decreasing large crowds in some places. The site will be a central place for school in terms of information, communication and technology. In this aspect, this would be considered as an opportunity because the site for this project is located at the mountain side of the school, since information, communication and technology equipment need to be place on higher ground that’s why this would be a great opportunity to have in this site an ICT building. Threats Climate disaster risk. There is also a threat from natural disaster like strong rainfall, strong wind and earthquake. In region VIII we have many strong typhoon landfalls in the past decade. Building a strong structural element of the proposed ICT building that can withstand natural disasters. Site is prone to soil erosion. Since the site has a clayish type of soil, it gets eroded easily during rainy seasons. Refining the landscape of the site and adding more plants can lessen the erosion of the soil. Site Planning Consideration Site planning refers to the organizational stage of the overall landscape design of the project. It involves the organization of land use zoning, access, circulation, privacy, security, 136 shelter, drainage, and other factors. In this design, climate, the potential users, existing structures surrounding the site and other factors should be considered. Safety and Security. The site has only one main entrance, it is in front of the IT building. Since it is an on campus facility, security facility and guards of the school would be utilized within the site. Vehicular Network. It indicates the location of the ramps and vehicular circulation routes and driveways in the site. The proposed site plan has only on adjacent interior access road directed from the main entrance of EVSU. Since the site is within school premises vehicles would only follow the school’s vehicular circulation pattern. Parking Accessibility. Since the site is located inside the school, allocated parking slots available in the school would be utilized and the researchers would provide additional parking slots in the site. Garbage Disposal Areas. The proposed site plan has garbage bins spread all throughout the site. Garbage waste would be collected and maintained by the school’s employed utility workers. Electrical Supply Source. The proposed site plan would be utilizing the electrical supply source of the university. The site has an adjacent electrical posts and utility poles that support the distribution of electricity all over the area. In case of power shortage in the site an emergency electrical supply would be generated by the school’s power generator and the researcher would provide additional generator room intended for the site. Water Supply Source. The proposed site plan would be utilizing the water supply source of the university which has a direct connection to Leyte Metropolitan Water District (LMWD) water lines. Supply cisterns of the school would be utilized in case of water shortage. 137 Laws and Codes. These are some ordinances, guidelines and laws that have been considered related to the proposed project. Here are some laws and codes that can be applied in the ICT building: a. IRR of BP 344 Batas Pambansa Bilang 344 or “The Law to Enhance Mobility for Disabled Person” the researchers will apply this law to be able to accommodate students and other persons with disability. This also will help the researcher to be able to apply the design standards of ramps, doors and other minimum requirements for accessibility. b. Presidential Decree No. 1185 Repealed by Ra 9514 Or “Revised Fire Code of the Philippines of 2008”. This law will help the researchers to fulfill and apply the safety equipment, fire extinguisher, sprinkler, emergency axe and etc. needed to insure the safety of the student from fire and other possible threats. c. Presidential Decree No. 856 or Code On Sanitation. This law will help the researchers to apply what is needed in terms of sanitary and other factors that can affect health of students and members of the faculty. d. Presidential Decree No. 856 or National Building Code of the Philippines. This will law will be the guide of the researchers in the planning and designing of ICT Building in terms of minimum standards and requirements. This law will regulate and control the location, site, quality of materials that will be used, construction and maintenance. 138 Vicinity Description The location of the proposed site was located at Brgy. 43-B Salazar St. Tacloban City. It has three main routes through Salazar Street, Sta. Cruz Street and Athletic Road in order to arrive at Eastern Visayas State University. Most of the student arrive at EVSU are from the Northern Part and Southern Part of Tacloban. Some are from the downtown area. The proposed site has an existing road access network that the university provided. This access road has a width of 6.80 meters. This means, it is two-way vehicular access and can arrive at the site by walking. The proposed site was located at the higher elevation of the university in which the site faced directly through the morning sunrise, university field, and even the downtown area of the city. the location of the proposed site is being considered by the researchers since it is the higher elevation of the university. This means the design of the ICT building must be wellplanned in order to resist the wind speed of the city. Not just to wind movement and speed but also to seismic events like earthquakes and also the precipitation amount that the site being received during rainfall for it could cause to soften the soil. One of the unique site features of the site is that it in-lined around the university built of the city which means, the location of the proposed site was being surrounded by schools and universities of colleges. This was being considered in the planning and design process by the researchers for the proposed ICT building. This allows the proposed structure to be known easily in the near future by its adjacent schools and university or colleges. Allowing more students and great job opportunities for the university will offer. Shortly, this will have a great impact in terms of the economic status of the university 139 There were adjacent buildings that the researchers have been selected. The buildings were as follows; CAAD building, Maintenance building, university Library, Graduate School Building, Information Technology buildings (2 existing buildings), and also the Life building. the researchers considered this one feature of the proposed site by simply selecting the most appropriate site in which has easy access in terms of maintaining the proposed structure and in which it can receive a great signal status that can be used by the security monitoring office of the university. Students or educators also could have easy access to the proposed site by walking or even vehicular access. The proposed site has an existing hill at the rear side and also a part of the university. It was being surrounded by bamboos and trees at its rear, side and even its front side in which later, can be used as an element in the design of the proposed ICT building and for its landscaping beautification of the proposed site. These natural features of the site were also being considered by the researchers for it has a positive and negative impact on the proposed site. The hillside can have a negative impact on the site for it can cause landslide and fall of debris in case if there is a seismic event. The positive impact is that it can be used as a wind barrier especially the “habagat” wind and also used to block the extreme heat temperature of the site especially at 1:00-4:00 PM daylight for it has trees around it. 140 This Site Fig. no. 107 Vicinity Description Source: www. earth.google.com Sun Path and Wind Direction Sun Path Analysis Sun path refers to the apparent significant seasonal-and-hourly positional changes of the sun (and length of daylight) as the Earth rotates, and orbits around the sun. The entrance facade of the proposed site for ICT building was facing in the northeast part. This means that the site as the rises to the east at exactly 5:57-6:00 AM (sunrise) receives an ample amount of sunlight. This light is much more favorable. At 6:00 AM up to 10:00 AM (daylight), the temperature of the proposed site increased. 141 As the sun travels from the east down to the south and reaches at 12:00 pm (noon), the proposed especially its left side of the facade received an immense amount of daylight form the sun. This means that this time is very much hotter in temperature and must be considered in the design of the facilities of the building. From 12:00 pm to 4:00 pm the sun travels from south to west. In this particular time, it is considered also as not a favorable temperature based on the climate/weather condition of the city. In this case, the proposed site for the proposed ICT building of the university was being covered by bamboo trees and the mountain itself at its rear side. By this, the unfavorable daylight temperature that will pass to the proposed site is being blocked by its geographical feature and its environmental tress. Lastly, at exactly 5:48 pm-5:50 pm (sunset) the sun settled in the west direction of the proposed site. Wind Direction Analysis The proposed was located at a higher elevation of the university. This means, the higher the elevation the greater the wind force that the site received. The two prevailing winds of the site were as follows; the Northeast Monsoon (amihan) and Southwest Monsoon (habagat). By this, from November to February experienced Northeast Monsoon winds and Southeast Monsoon winds from July to September. The proposed site also has a current wind speed of about 10.3 kph. (February 2020 analysis). This means that the speed of the wind was natural. 142 Fig. no. 108 Wind Direction Percentage Source: www.weatheronline.co.uk The figure above shows the current wind direction in percentage presentation analysis of Tacloban City as of February 2020.
