Based on the contract document, the estimated value of the contract can be calculated by multiplying the daily rates by the number of days worked. However, the contract does not provide information on the exact number of days worked. Assuming a 5-day workweek and 52 weeks per year, the estimated annual value of the contract can be calculated as follows: $2,375 per day (Certified Safety Professional) x 260 days per year = $616,500 per year $1,680 per day (Non-Certified Staff) x 260 days per year = $436,800 per year The total estimated value of the contract over 5 years can be calculated as follows: $616,500 per year x 5 years = $3,082,500 $436,800 per year x 5 years = $2,184,000 The average estimated value of the contract per year is: ($3,082,500 + $2,184,000) / 2 = $2,633,250 The total estimated value of the contract over 5 years is: $2,633,250 per year x 5 years = $13,166,250
