1-04-01.a INTRODUCTION

The general engineering design for theStructural, Mechanical, Electrical, Plumbing,Food Services, Fire/Life Safety, Security,

Telecommunications, Conveying Systems,Acoustics, and Audio Visual Systems will begoverned by the parameters set forth in theMaster Plan, the local and internationalbuilding codes, and the precedents set forth

by other Education buildings further alongin the design process.

The design team has reviewed availableinformation from Education projects alreadyunderway at Kuwait City, taking intoconsideration what building engineeringsystems are being utilized on thoseprojects. In order not to deviate significantly

from the technical, where possible we willfollow in a similar fashion.

OBJECTIVEOne of the Site Plan EnvironmentalSustainability Objectives is to conservewater. This goal will be accomplished bywater resource management techniquesalong with on-site wastewater treatment,

grey water reuse (for irrigation and cooling),and use of low water consumption fixtures.

OVERALL DESIGN The overall plumbing design will be finalizedafter the architectural and structuralschemes have been developed. Withcurrent knowledge in hand, we can assumethat the domestic water supply for each

building will come from the site water ringmain. This water will be metered and fedinto water storage tanks located within thebuildings. Water storage tanks will be sizedto accommodate two days worth of domestic water use.

In any educational institution, safety is of the utmost importance. Security proceduresfoster a safe environment, but should notdetract from the open, welcoming conceptof the College. The combination of electronic and procedural securitymeasures will ensure the safety of the

students, faculty, staff and visitors of the

Colleges. The College will incorporateleading-edge technology and securityconcepts widely used in large educationalinstitutions. Applying the concept of Concentric Circles of Protection, the designwill comply with the particular security zonerequirements set forth in the securitysection of the Site Plan.
