Requirements
for cost estimating |
|
4.2.1. |
We
must be able to produce a rough cost estimate in schematic
design and have that estimate automatically refined as we articulate,
select and substitute throughout the design process |
|
4.2.2. |
Support
for the full range of cost estimating approaches |
|
|
4.2.2.1. |
Follow
the ASTM E1557 standard to permit easy reformatting of cost estimate
data as the project is refined and more complete information about
materials and quantities are available |
|
|
4.2.2.2. |
Ability
to calculate cost per square foot based on occupancy or use
type (Useful during schematic design and design development.) |
|
|
4.2.2.3. |
Ability
to design to cost |
|
|
4.2.2.4. |
Ability
to take off quantities. Make quantity surveys "live," with
automated updates whenever the model is changed |
|
|
4.2.2.5. |
Ability
to price by building system |
|
|
4.2.2.6. |
Ability
to interface easily to cost content |
|
|
|
4.2.2.6.1. |
Ability
to substitute materials, products or systems and immediately
see the cost impact |
|
|
|
4.2.2.6.2. |
Integrate
with RS Means Cost Works and other sources of cost data |
|
|
| 4.3. |
Requirements
for schedule/ performance tracking: |

Automatically
update title blocks of user-selected drawings to reflect issue
date and status |
