The new science building includes classrooms, teaching and research laboratories and staff office areas.  The facility also includes high performance computer laboratory, oceangraphic laboratory, ocean floor modelling laboratory, physics and chemistry laboratories, geology laboratory with acid etching, x-ray diffraction laboratory, Nuclear Magnet Resonana Laboratory, laser research laboratory and organic and inorganic laboratories.  The facility includes 49 fume hoods including perchloric acid and hydrofluoric acid fume hoods, several exhaust canopies and local exhaust arms in several laboratories.   Fume hood exhaust system is variable air flow at the hoods, manifolded exhaust collection system with vertical discharge type exhaust fans.    Ventilation systems include redundancy in exhaust and make-up air systems for fume hoods.  Duct and pipe shafts have been provided for additional future services to allow for increased flexibility.  Steam to this building is supplied from the Central Plant.  Electrical systems include energy efficient T-8 lighting, emergency power, UPS, multi-media systems, fire alarm security, voice and data communication, and high speed internet systems.  Emergency power is provided for all essential services and equipment.  Some of the design challenges included discharge of fume hood exhausts, vibration free environment and RF shielding for Laser Laboratory.  Dispersion modelling analysis was carried out to determine the safe discharge heights for fume hood exhausts.

Sustainable Design - Mechanical and electrical design is energy efficient and exceeds ASHRAE 90.1 standard for energy efficiency.  Mechanical systems include variable air flow for fume hoods and DDC controls.  Sustainable design, energy efficiency and use of recyclable material were the key elements in the selection of system and building materials.

Connectivity - The building has been designed to provide flexibility in the teaching and research laboratories.  The building is wired for voice, date and high speed Internet to category 6 cabling standard with managed cable system.

Supportive Work Environment - The building is designed with staff offices and classrooms on the exterior part of the floors, while laboratories occupy the interior spaces.  All offices and laboratories are provided with access to natural light.  Building design coupled with - high level of comfort provided by mechanical and electrical will create very friendly environment in the building.

Budget Control & Management - Mechanical budget was established at the conceptual design.  Cost estimates were reviewed at each milestone and necessary changes were made to conform to the budget.  High construction activity at the time of tender resulted in tender prices coming in above the budget.  Post-tender changes restored the contract price to budget.
