Safety can be evaluated by following measures:

Accident Rate: Despite a study conducted by Tam and Fung (1998) concluding that the use of accident rates (AR) is superior to other indices, measuring performance simply by the number of accidents has long been regarded as an unsound basis for comparison.

Incidence Rate: The incident rate (IR) can be computed according to the number of lost time cases (lost time IR), number of days lost for all lost time cases (severity rate or lost workday rate), and number of fatalities, injuries and illnesses with or without lost workdays.

Experience Modification Rating: The experience modification rating (EMR) reflects the cost companies have to pay for workers’ compensation insurance.

Here is a good reference.

Here are some ideas:

Oh yes, of course for quality:

A) On time

B) Within budget

Thanks Ian, Time and cost are very important criteria. the attached article provides more details on measures of quality. A few of them are:

Time

Time is the duration for completing the project. It is scheduled to enable the building to be used by a date determined by the client’s future plans (Hatush and Skitmore, 1997). Alarcon and Ashley (1996) raised ‘effectiveness’ as a success criterion. They defined effectiveness as a measure of how well the project was implemented or the degree to which targets of time and cost from the start-up phase to full production.

Cost

Cost is another important measure. Cost is defined as the degree to which the general conditions promote the completion of a project within the estimated budget (Bubashait and Almohawis, 1994). Environmental performance Construction industry has been regarded as a major contributor to environmental impacts. Construction projects affect the environment in numerous ways across their life cycle (Shen et al., 2000).

User expectation and satisfaction

Users are those who actually work or live in the final products, they are the ones who spend most of time in the constructed facilities
