The Philippine Science High School-CAR Campus Dormitory sits atop a hill at an
approximate height of 25 m taken from the main assembly area of the Academic Building. The
dormitory started construction in January of 2004 and after two construction phases, it is
expected to be fully operational by the start of school year 2015-2016. It is expected to house
about one hundred twenty (120) students.
Entrance to the dorm is through a stairway from the service road level that opens to the
main lobby. At present, clearance from the edge of the walkway to the edge of the hill slope is
at 2 meters, thus the need for a setback extension as well as a slope protection/stabilization
system that would extend from the lobby landing area to the ground area at the Academic
Building level (referred to as ground zero).
The infrastructure project - Site Development Phase 3 addresses the need to protect
and develop the steep slopes between the dormitory and ground zero. With this project, PSHSCARC aims to establish a safer and more convenient environment for its students and personnel
by providing slope protection and/or stabilization between the dormitory and the academic
complex and at the same time provide pedestrian access between the two structures. Thus,
PSHS-CARC proposed to embark on a site development project which shall be designed to meet
the current and future structures and development within the area.
The project implementation will adopt the DESIGN-AND-BUILD SCHEME guidelines as
per R.A. 9184 and its Implementing Rules and Regulations.
1. To provide a background information regarding the preparation and submission of the
proposed project to the Designer-Builder;
2. To provide a background information regarding the proposed project which should be
handled in the shortest possible time, at the lowest possible cost and at an acceptable
quality and performance to the Designer-Builder;
3. To outline the “Work” of the Designer-Builder that has to be performed under the terms
of its contract with the PSHS-CARC.
4. To provide penalties in case of breach of Designer-Builder’s obligations
The proposed PSHS-CARC Site Development Phase 3, is composed of slope protection
and/or stabilization, and access ramp/stairway from the Academic Complex to the Dormitory
area. This site development project shall be designed on the basis of safety, functionality,
feasibility and aesthetics.
The proposed project shall have two main phases: the design phase and the
construction phase, and shall put emphasis on the most feasible slope protection/stabilization
method to be adopted.
The design phase shall include conducting an appropriate slope stability evaluation of
the site, which will form the basis of the proposed slope protection or slope stabilization system.
Ground surveys as well as up to date hydro-geologic data shall likewise be additional factors to
The completed structure shall be a slope protection/stabilization system designed on the
basis of the soil parameters obtained from site testing and shall serve the following purposes:
1. To provide ground support to the Dormitory;
2. To provide protection against lateral earth movements;
3. To provide easy, safe and well-lit access to the Dormitory area;
4. To provide adequate drainage of surface run-off from the Dormitory area.
1. General
The proposed site development is to be constructed within the PSHS-CARC Campus at
Purok 12, Irisan, Baguio City with an approximate total construction surface area of 815
sq.m. The project site is between two (2) existing buildings: the Academic Building and
Dormitory I with an approximate slope of 65 degrees at a slope height of 25meters.
2. Preliminary Documents to be provided by the Owner
The following documents will be provided by the Owner as preliminary data for the
a. Campus site development plan; and
b. GIS-based topographic map of the area
3. Preliminary Geotechnical Survey and Mapping
The Contractor shall conduct a geotechnical survey and mapping of the site as well as
slope stability analyses which shall serve as basis for the design of the appropriate slope
protection/stabilization system and pedestrian access to the dormitory area.
The Owner/Procuring Entity does not guarantee that the preliminary data provided are
fully correct, up to date and applicable to the project. The Contractor shall solely be
responsible for the accuracy and applicability of all data that it will use in its Design-and-Build
proposal and services. It shall also be responsible for the integrity of the detailed engineering
design and the performance of the structure irrespective of the approval of the
Owner/Procuring Entity. It shall also be solely responsible for the design and liable for
structural defects and/or failures of the completed project.
The Contractor shall conceptualize a site development solution that will preserve the
steep slopes of the land and at the same time provide a safe, comfortable, durable and
aesthetically pleasing campus environment.
1. General Requirement
The approximate surface area to be covered with the appropriate slope protection/
stabilization system is 815 sq.m..

General Concept
Site Development and Architectural Detail/Landscape Design Concept
Site development and provisions for aesthetics / architectural / landscape shall
be based on green-building concepts and shall be in consonance with the
existing design concept of the entire site. Similarly, it shall include a walkway
that will provide easy access to the dormitory area from the academic building
Drainage shall likewise be a consideration in this design concept as surface
runoff as well as a small amount of subsurface water is still expected to flow
from the dormitory area. The expected amount of water shall be directed
towards the rain pond located at the ground level of the academic complex.
The landscape component shall utilize easily propagating plants, grasses, trees
or shrubs which will mask the “hard” face of a concrete or stone retaining wall,
whichever the case may be.
Structural Design Concept
The structural design of the proposed slope stabilization / protection method
shall take into consideration the results of the following:
5.2.1 Soil geotechnical investigation;
5.2.2 Slope stability analyses;
5.2.3 Hydrologic survey; and
5.2.4 Soil and materials testing
Structural framing, foundation materials or anchorage materials shall be
composed of reinforced concrete and structural steel. These materials shall be
locally available and shall conform to the standards set forth by the ASTM. An
economical design shall likewise be produced, taking into consideration the
allowable factor of safety for structural design as well as for slope stability.
Should the slope factor of safety be less than 1.0, structural design shall
extend to providing the appropriate slope stabilization system to be introduced in
the identified area prior to the construction of the proposed slope protection
Electrical Design Concept
A general lighting design shall be proposed to provide proper illumination along
the walkway/ramp leading to the dormitory. The use of LED lighting systems is
recommended. Similarly, proper positioning of walkway/ramp areas is
recommended to be able to harness as much natural light as possible during
The design and specifications shall conform to, but not limited to the following standards
set by the:
a. National Structural Code of the Philippines (NSCP) 2010 edition;
