CEBU TECHNOLOGICAL UNIVERSITY COLLEGE OF ENGINEERING DEPARTMENT OF CIVIL ENGINEERING CE-PC 4114 Site Development Works Lecture No. 03 Outline Definitions Plan Reading and Review BOQ and BOM** Equipment and Tools** Definitions and Relevance Site Development involves preparing a piece of land for building or other uses. It encompasses various activities and processes that transform a raw parcel of land to meet the residential, commercial, industrial, or recreational needs of a given community. Site Selection covers the identification of locations that are appropriate for a specific development Guiding Criteria: Location Conformity with Land Use Accessibility Site Suitability looks at the intrinsic and specific technical qualities of the site and its capability to address the requirements for development Topography Slope Soil Characteristics Facilities Water Supply Power Supply Drainage Outfall Site Development/Land Development Plans  Typical Contents SHEET CONTENTS Cover Project Title, Vicinity Map and Location Map, Northings and Scale, Table of Contents Site Development Plan Site Development Plan, Land Use and Percentages, Total number of lots, Northings, scale contour line, Road number, Block number and Lot number Topographic Map Topographic map, Technical description, TCT No., benchmark, Northings and Scale Road Layout Road Layout, Road No. & stationing, Road ROW, Contour line, Details, Northings and Scale Road Profile and Lot Grading Plans Road Profile, Road Sections, Site Grading, Original Ground Elevation, Designed Grade Elevation, Details of slope protection, Northings and Scale Drainage Layout Drainage layout, size of canal/pipe, direction of flow, Details, Contour lines, Northings and Scale Water System Layout Water system layout, size of pipe, appurtenances, Details, Northings and Scale  Signatories PLAN/DOCUMENT LICENSED PROFESSIONAL Relocation and Boundary Survey Registered Licensed Geodetic Topographic and Structural Map Engineer Survey Site Development Plan with Land Use Computations Subdivision Plan with Computations based on Site Development Plan Road Layout Registered Licensed Civil Engineer Road Profile and Lot Grading Plans  Signatories PLAN/DOCUMENT LICENSED PROFESSIONAL Waterline Layout Registered Licensed Sanitary Drainage and Sewer Layout Engineer Registered Licensed Civil Engineer Sewage Treatment Plant Design Registered Licensed Mechanical Engineer and/or Registered Licensed Sanitary Engineer Street Lighting Layout and Professional Electrical Engineer Computations Power Distribution Layout Fire Protection System Professional Mechanical Engineer Aspects of Land Development Planning Considerations: Hierarchy of roads within the subdivision should be observed. Elevation of the road shall conform to the natural topography. Minimize the number of roads at intersection and avoid blind corners. Streets should intersect at right angle. Offsets intersection should be far enough to deter traffic from cutting diagonally across the road. A corner portion of the block should be cut in order to allow smooth change of vehicles and to provide a better visibility. The minimum corner cut is 3.00 m. for chopped. 1. RROW Road Right-of-Way Typical RROW: 6.5 meter 8.0 meter 12.0 meter 14.0 meter 2. Easement Under Article 51 of Presidential Decree No. 1067 or the Water Code, the banks of rivers and streams, the shores of the seas and lakes throughout their length shall be subject to the easement of public use within the following zones: a. 3 meters in urban areas b. b. 20 meters in agricultural areas c. c. 40 meters in forest areas. 3. Road Work Details A. Curbs and Gutters Concrete curb and gutter shall be constructed at the perimeter of the road to reinforce the road surface. It shall also be at least 0.275 in height to allow the water to flow at depth in the gutter and street. B. Construction Joints Construction joints shall be used to strengthen the slab and make it as one whole slab. If the joints are properly designs and spaced, a minimum cracking outside the joint would be expected. Construction joints are sawed in the hardened concrete and the depth of joint should be approximately 1/4 of the thickness of the pavement slab 4. Accessibility A. Dropped curbs shall be provided at pedestrian crossings and at the end of footpaths. They shall be ramped towards adjoining curbs with a gradient not more than 1:12. They shall be sloped towards the road with a maximum cross gradient of 1:20 to prevent water from collecting at the walkway B. Walkways/sidewalks should be kept as level as possible and provided with slip-resistant material. They shall have a minimum width of 1.20 meters. C. Provision of parking lot for persons with disabilities shall be allocated at a ratio of 1 slot for every 8 parking lots. 5. Planting Strips and Greening BP 220 PD 957 6. Drainage System should always be preceded by accurate field surveys. It shall be conducted to have a clear picture of the topographical features of the project area than what could be supplied by pertinent topographic maps. Study on the meteorological condition such as rainfall, atmospheric temperature and monthly number of dry weather days in the project area and vicinity shall be considered during the planning and design to minimize the effect of hazardous occurrences. A. Wastewater Treatment Sewage or other waste from a plumbing system which may be deleterious to surface or subsurface waters shall not be discharged into the ground or into any waterway unless it has first been rendered innocuous through subjection to some accepted form of treatment. B. Storm Drainage Storm drainage and sewerage system are separately designed for better treatment of sewage and better performance and efficiency of Sewage Treatment Plants (STP) C. Drainage Outfall It shall be directed to discharge in the direction of flow in the main waterways. 7. Water Distribution System A. Service Connections B. Fire Hydrant System C. Pipe Trench D. Pipe Thrust Block 8. Electrical System A. Electrical Poles B. Solar Street Lights 9. Others A. Perimeter Fence B.

Wear ___ color shirt. 2. Bring extra shirt, water, umbrella 3. Ballpen Field Activity (next meeting) 1. Prepare a sketch plan (for a school road/s) 2. Obtain measurements relevant to the land development scope present in actual. 3. Summarize data in table form quantities and measurements 4. Submit the field data. In-Class Activity (next meeting) 1. Prepare a BOQ for the altered version of the field activity with complete sets. 2. You are to construct a “new road”. Incorporate all learnings for BOQ preparation. 3. Submit via submission link at Google Classroom.  CEBU TECHNOLOGICAL UNIVERSITY COLLEGE OF ENGINEERING DEPARTMENT OF CIVIL ENGINEERING CE-PC 4114 Site Development Works Lecture No. 03
