Overall building efficiency ratio
R/u ratio
Gross-up factor
Grossing factor
Measure of efficiency and profitability for the owner - especially important in commercial office space construction
Overall building efficiency ratio
Net
________
Gross
Should be less than one
Net assignable area = all the spaces needed by the client (offices). Cross area is the whole building, including structure, mechanical,and circulation spaces not included in net assignable areas
R/u ratio / gross - up factor
Rentable
__________
Usable
Should be greater than one
Rentable includes common areas like lobbies janitorial closets, and mechanical rooms. Landlords charge tenants rent for a pro-rated portion of these spaces (so if you rent 11% of a floor, you will also rent 11%s of the mechanical room)
Usable = just the area the tenant will occupy to do business, including columns, private restrooms, private corridors within the office suite, and private storage but not lobbies, janitorial etc. That are shared by other tenants,
Grossing factor
Gross
________
Net
Greater than one
A grossing factor, established during programming, of 1.30 means that you will need to plan on 30sf of mechanical, circulation, etc space for every 100 sf of office space
Gross floor area (for programming)

Zones of occupancy
Determines occupant density, usually for HVAC and ventilation reasons, how close is the nearest human?
Public (25’ radius)
Social (12’ radius)
Personal (4’ radius )
Intimate (1.5’ radius)
A college bar will require more ventilation than a bank
IF the owner-architect contract stipulates that the architect’s fee will be 7%. Of construction costs, will the architect be paid for that 7% portion of the contractor’s overhead costs?
Yes, a percentage of the contractor’s overhead is included in the architects fee, The owners budget of the cost of work includes general construction costs, and profit, and overhead.
Business entity concept
The business is a separate entity and financial transactions of the business therefore, should be kept separate from personal financial record keeping, don’t pay for your dry cleaning with your firms credit card even IF you own 100% of the firm and the suit needs to be cleaned for aching meeting,
What are accessory occupancies?
Small spaces (the total area of which is less than 10% of the floor area of the story they are serving) that serve the main occupancy and require classification as different occupancy groups (ex. A small Office B in the corner of a factory F - 1 but do not require fire separation from the main occupancy
If the owner suspends the project, the architect can….
Suspend work
Require payment for work- to-date
Require payment of delay caused expenses
Submit a new schedule
AIA E204 2017
Supplementary to core 101 contracts for projects with sustainability goals
The owner must provide drawings, manuals, and building operational costs, appeal for certifications, ensure design fits sustainable guidelines, and comply with authorities on ownership and operations
Architect’s responsibilities to prepare for bidding
Finish CDs
Administrate bidding
Update cast estimates
Task dependency
The relationship of stop and start times for tasks
Start-start; nigh the start times of the steel folks who cut the rebar and the welders
Finish-start (also called natural dependency): align the finish time of the rebar welders with the start time of the concrete trucks
Finish-finish; align the finish times of the folks who remove the formwork from the concrete foundation and the rented pumps that keep the foundation excavation pit dry during construction
Prime contract
Prime contracts: Main contract with the owner for the work with the expectation that some of the work will be completed with the use of subcontracts, The contractor has a prime contract with the owner, and he hires a plumbing sub contractor, concrete sub contractor etc using subcontracts.
Multiple prime contracts: The project is fast- tracked, staged, phased, has multiple funding sources, or there’s a cm as agent managing the project on behalf of the owner, and the owner signs multiple prime contracts with a contractor, who in turn will sign multiple subcontracts: one for curtainwall while she waits for the rest of the drawings be to completed (Fast track) - one for the clinic that will be paid for with private funds and one for the attacked medical clinic that will he paid for with government funds (multiple funding sources) - one for the construction of the storage facility and one for ongoing maintenance at the same facility to be provided by the builder after the facility is occupied (multiple stages) - or one prime contract for the HVAC contractor and another prime contract for the framing contractor (multiple phases)
How does the owner pay the contractor?
Unit cost: agrees to pay $245,000 per housing unit
Cost plus fixed fee: $1.6 estimate for the cost of the project plus $300,000 in fixed profit for the contractor. No limit on change orders, which can net the contractor additional profit
Guaranteed maximum price (gmp): like a cost plus fixed fee contract, but of the project is delayed or the price of materials goes up beyond a total project cost of 52 million, the contractor has to complete the project and eat the extra cost
Stipulated (lump) sum : owner pays contractor $1.9 M to build everything in the contract, period.
Supplemental instructions to bidders is Architects supplemental instructions
Supplemental instructions to bidders: modifications to general conditions in contracts ( providing supplemental information during addenda)
Architects supplemental instructions ( ASI): after construction is underway, like a change order but so minor it won’t affect the cost or project schedule
Top down vs bottom up project budgeting
Top down budgeting: start at the “top” with the gross fee the owner will pay your firm, subtract expenses to see what is left for design time
Bottom up budgeting: start at the bottom with each person who will be working on the project, their hourly rate, and the number of hours you estimate they’ll need to work. Each task is tallied upwards. Time consuming but more accurate. Good for multi-faceted, large projects
Project cost = sum ( hours/task X dollars/hour )
Smoke pencil
For tracing the source of building skin air leaks
Use a blower door test to pressurize and de pressurize the building to measure total building cur leakage. Where it’s pressurized, run a smoke pencil/pen as a wand and watch smoke move in or out of seams in the building skin.
If the contractor requires information from the owner, the architect has_____ days to give that information to the contractor.

If the owner provides building materials, does the architect still get the 7% of construction costs as fees?
Yes, the budget is based on the cost of work and labor regardless of if materials are supplied the owner by
