Overview The Observatory summit building includes the infrastructure

and equipment required to support, operate, and facilitate night time observations.

The facilities, offices, and support equipment are organized

throughout the building taking into consideration, personnel workflow, daily work logistics and overall form, fit, and function.

Preexisting building exhaust tunnels will continue to be used to remove heat and minimize thermal loads from the building.


World class observatories


Motivation – Rebuild and Redevelop

Development process, from 1999 (left), 2005 (middle), and 2007 (right)


Successful example: Pennsylvania Station (New York City)

Justification MSE will reuse the CFHT site and build upon the existing

observatory, infrastructure, facilities, processes and expertise.

CFHT’s site on Mauna Kea has some of the best seeing in the northern hemisphere therefore, to better meet the needs of it’s users, an obvious option is to upgrade the telescope with a larger primary mirror and equip it with new instrumentation so that more competitive science can be offered.

The knowledge and experience from current employees will vastly streamline the engineering and construction of a new telescope facility.


Scope

Provide a first pass conceptual design of the observatory

building equipment and facilities required to operate a 10m class

telescope

Create a list of equipment and facilities required based on

existing MSE demands and development plans

Research existing equipment used at other 10m class facilities


Goals

Model the building design so existing equipment and

infrastructure can be reused wherever possible while meeting

new requirements

Utilize past experience and support demands needed from

observatory personnel to create a modern, simplistic, and logical

design layout

Position equipment and support services in ideal locations

based on telescope configuration and technical needs
