Value of Potential Loss. Calinan Public Market sells different commodities from dry goods to vegetables to meat production. Since Calinan
Public Market stands to be more of an agricultural production enterprise, the possibility of the declining sales may come especially during non-seasons. Regardless of this matter, the public market managed to run because of other demands.
The valuable peak seasons for durian and other popular fruit and vegetable commodity made the market popular more especially to the tourists and local consumers. However, the non-season days may come and may eventually change the face of the market during these days. The consideration of this loss maybe patched up by advertising other commodities in the market making the market a much demand more for the public.
But, being the basic need for a community, Calinan Public Market may really run even it is not season for some commodities or other productions. However, the reality of this phase may be reduction of a possibility of a huge economic help to the community.
Time-Motion Studies. Calinan is about 27.13 kilometers reach from City hall resided in downtown which then will took for about an hour drive for jeepneys, trucks and vans. Being a sub-urban community Calinan is the center of the North-eastern part of Davao. It serves as a drop of different trucks and automobiles that will catch up to the next drive either towards downtown or towards uptown which includes Marilog and Baguio Districts. It will take for about 40 minutes to drive to Marilog, 25 minutes toward Baguio, and 15 minutes toward Tugbok.
Since the Calinan Public market is in the metro, the drive from downtown will only took for about an hour also depending upon traffics. But
for the nearby residents, Calinan Public Market is just a walk reach taking 5 minutes or less regardless for those in much further areas.
Figure 5 The Site Location
Traffic Analysis. The grid type framework of Calinan is completely visible in the map as shown in figure 5. With a total of 143.5 km of concreted roads, transportation is made possible though not all roads are concreted. These roads are boxing out properties and establishments like Calinan Public Market.
Calinan Public Market is approximately an 80m division between Honesto Garcia St. and Davao-Bukidnon Highway. Near Calinan Public
Market is a trumpet intersection of the Davao-Bukidnon Road and the Villafuerte St. Within the market there were two roads with a width of three meters. These small streets are convenience streets for deliveries and exportation. However these streets don’t have sidewalks and application of proper ramps for differently abled people. During peak seasons or market days (Saturdays and Sundays), ambulant vendors are rampant to which is a problem since they are occupying the walks which leads to congestion. The addition of unorganized loading and unloading of pedicabs and motorcycles makes the problem even worse. The barangay however responded to this situation. They managed to close the Honesto Garcia St. as a one way street to prevent this congestion. Calinan Public Market managed to put parking spaces for jeepneys and trucks who delivers the commodities to the market. However, some of the parking spaces are made terminals routed for uptown trips. The traffic within and around the public market has a lot of constraints and most of these constraints are caused undisciplined customs of the residents.

Behavioral Patterns. Calinan Public Market has several stalls for lease. These stalls have been occupied by vendors who pay 500PhP monthly which are then designated into either section wet or dry depending upon what is being sold. The market opens as early as 7:00 am and before the opening hour, vendors managed to prepare the stalls and commodities being sold. When clock struck 9:00am customers are starting to flood up the halls up to 11am. These are the peak hours. The peak hours then will be back by 4:00pm until 7:00. After then, when twilight came, barbecue stalls started to open serving drivers and travellers for their food stop. The cycle remains the same until Saturdays and Sundays comes, things will be much busier in the market. Peak hours are much longer; market stays awake until 10.
For the entire day, from the time it started to open, market security guards are roving and shifting as schedule dictates. They work five days as well as the office. However offices are only working from 8:00am until 5:00pm.
Space Adequacy. Currently, there were about 429 stalls in the market. Some of these stalls in the market have not yet been occupied but there are a lot of ambulant vendors around the market. The market may seem to have enough stalls but some of these stalls costs a lot for the starting vendors to pay. Therefore, in that case, vendors tend to occupy the sidewalks and sell there. The situation results to congestion and the sidewalk, hallway and
streets widths become insufficient. Addition to the result regarding to the situation is the crowding of people especially during peak season or holidays.
The evident traffic congestion is also a contribution of lacking enough parking spaces for vehicles like, jeepneys, trucks and other automobiles. Currently there no definite parking spaces since the sparking space aren’t concreted or developed.
Type/Intensity. Calinan Public market has two market buildings and stalls inside. These market buildings are designated into wet and dry sections. Dry section includes the dry goods such as abacca, dried fish and etcetera while wet section includes meats. These sections are very important and verify the identity of public market the most. In order for the market to function better, the market has other facilities like slaughterhouse and the administrative office. Minor facilities like parking lots plays also a big role especially when in it comes to deliveries.
Physical Challenged Guidelines. The special consideration for the welfare of the disabled has been neglected in the current Calinan Public Market. Ramps should be provided with a scale ratio of one is to twelve. Furthermore, there should be sufficient space for a wheel chair to pass the walks with a supposed minimum length of 1.5m as stated in the National Building Code of the Philippines and BP 344. Furthermore, according to the Public Market Code ramps shall be strategically located for purposes of visibility, near the approach point to the market structure, and shall conform to the provisions of the existing accessibility law which requires buildings, institutions, establishments and public utilities to install facilities and other devices to enhance the mobility of disabled persons. Therefore, management
shall provide ramps and other convenient facilities related to make the market functional and have well-rounded activities. For example, regular stairways shall complement the market systems and activities. Along with the stairways are the facilities like toilets intended for the physically challenged people. Form
Site Analysis. Calinan Public Market is located 7°11'26"N 125°27'16"E Davao City. It is currently standing in a 14,280 sq. m lot (shown in figure 9) surrounded by the roads Davao-Bukidnon Highway, Honesto Garcia St. and the ends of the Villafuerte St. Since the area is too small, the redevelopment will be extended towards North-West filling up the whole block making the site a total of 28, 331 sq. m (Shown in figure 12). The market’s site is quite an irregular shape. It is surrounded by commercial establishments also like NCCC supermarket just across the market, One Network Bank and Mercury Drug.

Soil Analysis. According to the data provided by the Mines and Geosciences Bureau Region XI, Calinan District is within the perimeters of Calinan Quadrangle. Generally, the area can be grouped into five (5) major geomorphological units (or terrain mapping units) which are as follows:
a. Fluvial landforms
b. Lower Talomo volcanic foot slopes c. Denudational landform in volcanic rocks d. Denudational landform in sedimentary rocks e. Karst landform
Fluvial landforms. The fluvial landforms define the Davao River and tributaries active channel and floodplains.
Lower Talomo volcanic foot slope. This area defines the broad and elevated flatlands covering the Calinan area. It is chiefly underlain by gently dipping volcaniclastics.
Dedudational landform in volcanic rocks. Intercalated andesitic lava flows and pyroclastic rock with dominant denudational processes made up this landform. It occupies the southwestern part of Calinan quadrangle.
Denudational landform in sedimentary rocks. A greater part of the quadrangle is occupied by the sedimentary hills and slopes. Several Sub-units can still be delineated within this landform based on relief and specific origin, however, due to the reconnaissance nature of activity, further delineation of sub-units was not attempted to this time. It is interesting to note that a lot of mass movement were mapped within this landform.
Karst landform. Karst landform develops mainly on areas underlain by limestone especially if excess rainfall is available. Karst landform can be recognized within Malabog area wherein positive and negative landforms can be identified.The section of the property with relatively steeper slopes defines the southeast boundary. The area is generally underlain by intercalated and compacted pyroclastic deposits with lenses of volcanic flows which, in turn, an overlain by relatively thin blanket of surficial deposits. The basaltic- andesitic volcanic rocks in the property are most probably derived from the Sibulan-Talomo-Apo volcanic complex, which is responsible for the most widespread lithology in the area, effectively blanketing a substantial portion of Catalunan Pequeno and other adjacent barangays.
Calinan still belongs to the area where it is low in susceptibility of landslide however it may be prone to flooding with a rating of medium susceptibility since it is near to the Talomo River, and the river connected towards Davao River.
Based from the area’s geological environment and the foregoing field findings, the property inspected is capable of accommodating most forms of development. The underlying lithology is generally a competent foundation material, capable of supporting light to moderate infrastructures (e.g. residential houses, small buildings, etc.). The geohazards identified in the area are ground shaking, flooding and possible volcanism. Ground shaking can be mitigated by the proper engineering designs of structures. As regards possible volcanism that is subject to official classification of Mt. Apo status by PHILVOCS, vigilance and alertness would be sufficient to prevent the loss of lives.

FAR & GAC. According to P.D. No. 1096, THE 1977 NATIONAL BUILDING CODE OF THE PHILIPPINES (NBCP) the percentage of site occupancy by a building/ structures shall be taken at the ground level and shall be exclusive of courts, yards and light wells. Courts, yards and light wells shall be measured clear of all projections from the walls enclosing such wells or yards with the exception of roof leaders, wall copings, sills or steel fire escapes not exceeding one point two meters (1.2 m) in width.
Climate Analysis. In Philippines, there are only two seasons the wet and dry. The country is located above the equator and is included in tropical zone. Annually, Philippines is hit by typhoons. Typhoons have a great influence on the climate and weather conditions of the Philippines. Philippines has the average temperature of 25.5 degree celcius. A great portion of the rainfall, humidity and cloudiness are due to the influence of typhoons. Due to high temperature and the surrounding bodies of water, the Philippines has a high relative humidity. The average monthly relative humidty varies between 71 percent in March and 85 percent in September. The combination of warm temperature and high relative and absolute humidities give rise to high sensible temperature throughout the archipelago. It is especially uncomfortable during March to May, when temperature and humidity attain their maximum levels.
As to Davao City, it has an average of monthly temperatures above 26 °C (78.8 °F), and average monthly precipitation is above 77 millimeters (3.03 in).

Code Survey and Surroundings. Calinan Public Market belongs to the Minor Commercial Zone (C-1) as the City planning has defined through the certificate. This indicates that the market is in the right zone for running commercial business.
The Calinan Public Market Complex is a redevelopment of the current market. The current market doesn’t have trees or landscaping, the site is totally flat with all of its buildings and facilities designated within the site. However, the market could be attracting if there were any natural features but it wasn’t implemented due to the small space and a huge need for more stalls and facilities like additional parking spaces for vehicles like trucks and jeepneys.
Psychological Implications. Residents in Calinan as surveyed wanted change for the public market and very much prefer supermarkets rather than the latter. The
implication of the statement is that the atmosphere really affects the point of view of the customers in purchasing and patronizing markets.16 people who were avid customers of
both types of markets were asked if they prefer supermarkets over public markets. They were also asked if whether of the two are sanitized
The data shows that although the consumers think that public market has cheaper and fresh products they would still prefer supermarkets over public markets. The reason behind the preference may be justified by question number one and two. Consumers still think that supermarkets are cleaner and much safer to purchase goods.

Point of Reference/Entry. When driving from downtown towards Lacson along Davao Bukidnon Highway, the intersection’s round plant box is very visible. It is already an indication for directions especially knowing the location of the site aside from being the billboards local stand post.
According to Mr. Elmer Juyo, the market’s officer in charge, the development of the market has no definite point of access. People could come in from anywhere and from anytime they want that’s why they didn’t have any data when it comes to average cutomers who patronize the market. Therefore, Calinan Public Market is as public as it was named. The slaughterhouse is the only place where there were restrictions of access.
Building or Layout efficiency. The 17,291 sq. m. total area of the current Calinan Public Market isn’t really enough for the entire routine of the users. Since the routine of the users include mobility of vehicles and transactions. Some stalls remained unoccupied but there are many ambulant vendors placing themselves within the site. The whole area wasn’t totally efficient when it comes to layout or the framework of the development because of the said situation. Maybe the reason is both the organization itself and the development itself.
Cost/SF and Equipment Costs. For a government funded development Calinan should have justifiable costs for the said project. Since it is a redevelopment it will really make a huge change for the market. There would be additional facilities to which therefore sums up estimated 25,000PhP gross per area. When multiplied to the total area it will sum up over 24,475,000PhP.
Economy
Cost Parameters and Maximum Budget. Cost per square meters will be defined 25,000PhP. The latter then is multiplied to area unit per 429 stall owners, 25 office workers, and average customers daily is approximately 700
customers. That’s a total of 24,475,000PhP without the total additional costs for extensions.
Market Analysis. Currently, the City Economic Enterprise is expecting the Calinan Public Market to earn 680,000Php per month. Calinan Public Market is already fourth of the largest earning public markets in Davao next to Toril Public Market, Agdao Public Market, and the Bangkerohan Public Market respectively. The change for the development of the Calinan Publlic Market may gradually affect and increase the monthly income of the market.
Energy Source Costs. Calinan Public Market relies its electrical power demand to the Davao Light Power Company. The company charges the overall commercial centers like public markets 19.38 centavos per KW/hour. The average consumption of a commercial structure like public market is about 15.5 Kwh/sf daily. 70% of all energy consumed in a typical office building, with an additional 20% of energy consumption used to power office equipment. The remaining energy is consumed by water heating, cooking, and refrigeration systems, as well as other miscellaneous uses.
Activities and Climate Factors. The continuous maintenance of the market is very needed as of the current. Since the public market resided in the tropics, it will really experience high humidity and moisture which eventually deteriorate some building materials. One of the most important building material is the roofing in the market building. The holes in roofing does affect greatly on the products the vendors are selling.
Economic Data. 64.74% of Calinan residents are earning 5,000PhP below (1), 8.45% are earning 5,001-10,000PhP (2), 6.56% are earning
10,001-15,000PhP (3), 6.00% are earning 15,001-20,000 (4), 3.18% are earning 20,001-25,000PhP (5), 3.46% are earning 25,001-30,000PhP (6), 7.61% are earning 30,001Php and above (7), with a total of 4,878 households. People here tend to establish livelihood through having businesses especially regarding agriculture and commerce. As shown in the data below as gathered information from the Barangay Profile, there is a huge percentage of people here in Calinan are only earning 5,000PhP below. Although 53.03% percent of the households are self-employed it seems that the incomes of the residents are very low.

LEED Rating System. Calinan Public Market needs a huge maintenance and recovering what is the best out of what’s present could really be hard especially when the structure itself is deteriorating. The obvious holes in roofing, which is a huge problem when raining, are one of things that need action.
In order to reduce the economic costs of maintenance, especially when replacing stuff like roofing, needs a resolution. The resolution is the resiliency of design. Resiliency of design means the stand of the building through time and time to time weather changes. It is incorporated with Environmental design which implicates the vision of a building that does minimal environmental impacts. Both of the design implication would be valuable to the redevelopment of the market.

Significance. Since most of the neighbouring establishments are commercial spaces, there is no need for consideration of historical preservation. However, the development shall take consider the nearby park
