PSHS CENTRAL VISAYAS CAMPUS

I am Dan del Rosario, a registered licensed Architect from Batch ’85. Last October 22-24, together with fellow alumnus Irwin Cafugauan from Batch’88 and representative of Aghamroad.ph, went as volunteers to visit the PSHS Central Visayas Campus to see what the alumni can do to assist the school in recovering from the recent 7.2 magnitude quake in Bohol and Cebu.

Introduction

This is my Visual Damage Report for presentation to the PSHS BOT and the PSHS NAABOD. The slideshow of pictures aim to show the stresspoints sustained by the affected structures. An official damage assessment is recommended to declare the structural integrity of these buildings, and this should be undertaken by Government Agencies or third-party qualified Structural investigators. The said assessment will be the basis for the repair plans and design.

Visual Damage Report

The following buildings sustained the most damage:

•Academic Buildings I and II

•Admin Building

•Boys and Girls Dorm

Visual Damage Report

Academic and Admin Bldgs

View from Road, showing wall cracks with possible structural column damage on

the corner.

Academic Building II

Damages to Portions of Wall of Roof Deck


View from Academic Building I, showing wall damages between doors and dormer

windows. It shows possible lack of stiffener members.


Damaged corner wall plaster with possible structural column damage.


Wall plastering peeled off. The brown portions indicate possible presence of soil

in the aggregates used.

Academic Building I

Wall Damage between door and window showing possible sub-standard Concrete

Masonry Units (CMU, aka hollow blocks). Cement mix poured into the holes is

intact.


Another instance of crumbled CMUs, while the concrete mix inside remained intact


Another view showing chipped-off wall plaster.


View of Academic Building 1 from Building II. Bldg I is older than Bldg II but the

latter seemed to sustain more damages.

Academic Building I

Wall aggregates which fell on the floor.


View from inside one of the classrooms showing wall damages. This portion

exposed the electrical pipes and conduits. It is recommended that a thorough

electrical and plumbing check should be conducted.


Corner wall plaster cracks.


Wall plaster cracks found outside the toilets.


Wall plaster cracks Inside the toilets.


Upper wall of Academic Building I which fell on the IT room of the Admin Building.

Academic Building I and II

The damage due to the collapsed upper wall of Academic Building I.

Admin Building

Boys’ and Girls’ Dorms

Wall portions are being repaired in preparation for the school lre-opening. The

lower floors will be occupied by female residents who were displaced due to

damaged Girls’ dorm

Boys’ Dorm

Wall damages inside the boy’s dorm study area

Boys’ Dorm

Part of wall apex below the eaves collapsed. This also shows possible damage of

the roof framing

Girls’ Dorm

Same damage on the other side of the building

Girls’ Dorm

Wall plaster cracks also due to possible lack of window stiffeners.

Girls’ Dorm

The canopy/overhang is slowly sagging, especially after each strong aftershock.

Temporary posts are recommended on the outer corners. Same preventive

measures should also be done to the canopy of the Boys’ Dorm.

Girls’ Dorm

This is the wall facing the cliff. There’s a possible structural movement of the building members and the retaining wall here. As mentioned, further analysis by a Certified Structural Engineer is highly recommended

Girls’ Dorm

Damages on the interior Toilet walls on the cliff side.

Girls’ Dorm

Window wall surface cracks.

Girls’ Dorm

Landing / upper floor beam line separated from the upper wall, showing possible

structural movement.

Girls’ Dorm

Surface cracks on the columns. Further proof that structural assessment is

recommended.

Girls’ Dorm

It became evident to us that our roles were to:

•facilitate in coming up with the best design for the temporary classrooms

•help in coming up with a strategy for the funding of this project

•and to ensure that the PSHS CVisC team meet their Nov4 deadline of resumption of classes.

The school’s resident engineer and ADTECH instructor collaborated with me to come up with the design for the 8 temporary classrooms that need to be built around the campus grounds. Highest considerations are the cost and durability of these classrooms with the possibility that it would take more than a year for the academic buildings and girls’ dorm to be fixed.

Temporary Makeshift Classrooms

The makeshift classrooms will be made of local materials such as wood members,

plywood walls, GI roof, insulation and concrete. Instead of windows, vertical slats

are incorporated around the structure. This design focuses on natural ventilation

and low construction cost.

Perspective

After surveying the campus perimeter, we have determnined the best locations for

the 8 temporary classrooms.

The classroom will be attached to the existing stage as shown above.

Location – Temporary Classroom 1

This is the level clear area right below the stage area. Easements on the cliff were

considered.

Location – Temporary Classrooms 2,3,4 and 5

This is the clear area beside the Gym, after the location of the proposed

Academic Building III.

Location – Temporary Classrooms 6 and 7

This is the corner area of the Gym, overlooking Bohol

Location – Temporary Classroom 8

As of this writing, construction has begun for the 8 classrooms. Classes were

rescheduled to re-open on November 11.
