what is the steps in order when you're site measuring- what do you do first etc

1. walk through then sketch rough floor plan
2. refine the drawing- make it more accuracte- room size ratios like bigger room is bigger
3. Determine dimensions required
4. measure key dimensions
5. draft up the floor plan and elevations


what accuracy is needed when site measuring and why

1/4" is fine- not much bigger because the errors will add up over a long length and create larger inaccuracies


If an overall dimension and the addition of multiple dimension to get the overall is off by __" or more you should go back and re-measure



in a site measure, why is it ok to be off by 8" or less

generally if you are not coordinate with existing construction or building element, it's not that important.


what is an EDM when it comes to measuring

an electronic distance measurement- laser based


name some ways you can determined how much space is needed for a room

1. multiplying the amount of space required per person x the number of people in the same area
2. amount of space needed for objects
3. built in set of rules related to the activity of the room (basketball court)


what do you need to calculate for a client once they know how much space they want and they are looking to lease a space

rentable area required


what is the total area or gross area when talking about a leased space

amount of floor space required overall space

it will be greater than the total of all the required areas


what is the net area when talking about a leased space

or net assignable area- actual occupant area required by client.

does NOT include circulation space or incidental space like closets, columns, walls


what is the efficiency factor in general (for prelim planning)

how you find out the total space required is by using an efficacy factor- ratio of one area to another


what is the efficiency factor for a leased space and what do they depend on

the ratio of net area to the total occupant area. Depends on the type of occupancy, size of individual spaces and how well the space is planned (like how much space is used up for circulation vs space you are actually using). This factor is given to us based on the building type like office, retail, residential, hotel.


what is the occupant area of a leased space

total portion of a building being actively used by a tenant (does not include common building corridors)


what is the estimated required occupant area of a space

calculated by dividing the net area by the efficiency factor (dividing the actual space the client is using by the efficiency factor given for that type of space)


what is the rentable area of a leased building

the tennent's occupant area multiplied by the load factor that accounts for the shared portions of the building


what are the typical efficacy factors of an office space, school and apartment and retail

office 0.75-0.8
school: 0.6-0.66
apartment: 0.66-0.8
retail: 0.75


how do you calculate how much space a client needs to rent in a building with building load factor of 1.2

1. find the actual space the client needs including circulation- the gross area= the net area x the efficiency factor
2. find the rent able area which is the gross space x the building load factor supplied.


how do you determine what sheet size to use for a project

an office might have a typical size or by the size required to draw a floor plan on one sheet without dividing it in to sections


what non typical things does the NCDIQ book say should be on a title block of a drawing

consultant name
space for professional stamps if required
copyright notice (optional)
key plan (optional but good for large projects)


what is a one-line or single line diagram

drawing prepared by the electrical engineer that shows a diagrammatic representation of the electrical system from the primary feed in the building to individual lights and power panel boxes. Branch circuits are not shown usually. shows the conduit and conductor sizes


how can you make sure your drawings are coordinated with consultants- what are some ideas

1. regular meetings
2. send out progress prints
3. notify all consultants if any changes occur


with is BIM

building information modelling- 3d model of building- can do floor plans and elevation- have info attached to doors and partitions and can be used to estimate materials and costs
