Glossary/Acronyms
| A/E | Architect/Engineering - the project's designer |
| ANOVA | Analysis of variance. Here we only used one-way ANOVA, which is a statistical technique used to determine if groups (samples) came from different populations. (Is there really a difference between these groups, based on the samples we took?) http://en.wikipedia.org/wiki/ANOVA.If you are only trying to distinguish between two groups, you would use the t-test. If there are more than two you need to use one-way ANOVA. |
| Best Value | A procurement method that awards contracts based on a combination of qualifications and price. |
| CM | Construction Manager. Here it is used to designate the prime or general contractor in a CMAR system. |
| CMAR | Construction Manager at Risk. A project delivery system |
| CMR | Variant of CMAR |

| DBB | Design-Bid-Build. A project delivery system whereby the A/E designs the project completely, then the owner solicits bid for the construction. Usually synonymous with "low bid procurement." |
| Fast tracking | Taking items of work or procurement out of a main contract so that they can be done earlier - for example before design of the entire facility is complete or before the main contract is let. |
| GMP | Guaranteed Maximum Price. The price the CM agrees to in a CMAR contract. |
| HVAC | Heating Ventilation and Air Conditioning. "Mechanical Contractors" often do HVAC and "plumbing." Fire protection, i.e., sprinkler systems, are sometimes done by a mechanical contractor and sometimes by a specialty contractor. |
| QBS | Qualifications-based selection. A procurement method that awards based on qualifications rather than price. http://www.illinoisqbs.org/ See best-value |
