Constructing Environments Karen Dionisio-See Week 10
Activity: On Site (Take 2) This week we revisited the Oval Pavilion and observed the construction and structural progress it has made.

EVIDENCE OF PROGRESS MADE IN THE BUILDING Wall system of this part of the building has been constructed and temporary joists have been removed.

CONSTRUCTION AND STRUCTURE
Vertical and lateral reinforcements are laid to lock and to stabilize the concrete formwork (Ching 2008: 5.04). The vertical reinforcements are to carry compressive loads and to withstand tensile forces when it experiences lateral forces (Ching 2008: 5.04). Moreover, this limits the occurrences of creeps and shrinkages in the column. The main part of the structure that is being developed is the formwork, mostly those made of concrete.
The lateral reinforcements are to control the vertical reinforcements and helps the columns resist buckling (Ching 2008: 5.04).

CONSTRUCTION AND STRUCTURE Roof System The roof system is lifted higher for function purposes, which includes the ability to reduce the noise. Construction of roof structure

Structural Steel Framing This formwork is nearly finished in the construction process. Since this structure is difficult to work with, most of it is made offsite and prefabricated to a specific design (Ching 2008: 5.35). With this, the construction process is faster and more accurate than the ones made in situ. These would also serves as the framing of the windows for the building.

CONSTRUCTION AND STRUCTURE
Timber is used for the materials of the columns for aesthetic purposes. They are laminated to provide an equal amount of strength as steel (WoodSolutions 2013). Braced Frame For resisting lateral forces such as wind and seismic, braced framing or a giant truss attached on the steel and timber columns of the south end of the Oval Pavilion is used. It is made of a combination of steel and timber diagonal frame to strengthen the structure (Ching 2008: 2.22).

MATERIALITY & FUNCTION LAMINATED VENEER LUMBER One of the materials used in the building is the LVL that has a similar strength as solid timber, concrete and steel (might be for the beams, lintels, purlins, trusses or formwork). It is manufactured by gluing peeled or sliced thin wood together under heat and pressure (WoodSolutions 2013). Moreover, the main advantage of using this type of timber is its resistance from any pest such as termites because of the toxics used to bind the wood together.
ALUMINUM FLASHING
Flashing is used at the end or top of box gutters. This is a continuous sheet of metal like aluminum to provide waterproofing for the building (Ching 2008: 7.18). It brings water that enters in the cavity walls out of the buildings.
