Program phase steps

1. Review existing documents and facilities
Archit­ect­ural, Organi­zti­onal, Technical documents
2. Benchmark comparable facilities
Visit other facilities
3. Conduct program meetings
reveal what a system currently does, what it needs to, and what people wnat it to do
4. Write program report
report containing user needs and a concep­tua­l/f­unc­tional system descri­ption as well as impact it will have on existing spaces
5.Dist­ribute program report
owner, end users, IT, archit­ects, constr­uction manager, GC, integr­ators, cost estima­tors,
6. Approve the program report
formally approved report becomes basis for the design

Program report contents

executive summary
brief overview of entire document
systems descri­ptions
descri­ption of each type of system
infras­tru­cture consid­era­tions
impact to lighting, electr­ical, mechan­ical, acoust­ical, data/t­elecom, struct­ural, archit­ect­ural, interior, budget impacts
Special Issues
major obstacles, schedule issues, specific options for specific spaces
Prelim­inary budget and terms
Estimate of cost
breakdown of probable cost
basic breakdown of costs of rooms or equipment
additional costs

Key elements of a Project

Scope: what is being done
Time: Effort and Duration
Cost: Labor and Equipment
Quality: Ensuring perfor­mance meets expect­ations
Risk: Threats, Opport­uni­ties, and Response Strats

Needs analysis steps

1. Talk to stakeh­olders
2. Review exisiting documents3
3. Site survey
4. Conduct program meetings
5. Write program report.

Two Envelope Bid Method

1. Create Request for Qualif­actions (RFQ) and Request for Proposal (RFP)
2. Target potential providers
3. send out RFP/RFQ to potential providers
4. Review Qualif­ica­tions response without opening proposal and create "­short list"
5. interview "­short list" and rank them
6. Open proposal for the higest ranked provider and if fee is within range, they win the bid
7. If fee is too high move on to the next highest ranked provider until one falls within budget.

Qualif­ication based selection

1. Create Request fo Qualif­ica­tions (RFQ)
2. Target potential providers
3. send out RFQ to potential providers
4. Read responses and create "­short list" of 3-5 providers
5. Interview "­short list" and rank them
6. Negotiate with highes­t-r­anking firm for project fee
7. If acceptable fee and scope cannot be establ­ished move to next provider

Roles of Video Processors

Adjust timing­/signal strenth
Ensure continuous transi­stions, ie avoid crash switching
Correct defici­ences in the orginal signal
Adjust picture color, contrast, brightness
Change format of signal

Composite VS Component video

Composite: combines luminance and chroma info into 1 cable
Component: luminance and chroma are in seperate cables
