Ingeneral, very small or very large projects experience a significant loss ofproductivity. This includes a general allowance, job preparation allowance,personal care allowance, extra man allowance and moving time allowance.Other condition factors include walking/driving distance, height, underground orlow rooms, enclosed spaces, dust, temperature, noise, protective clothingrequirements and congestion.• Construction Equipment and Tools – it is assumed that all equipment will benew; however, weather and local conditions will impact the typical operation ofequipment.• Weather – temperature is one of the largest factors when assigning aproductivity factor.• Estimate Details – Level 1 Major AreaMAJOR AREA 11 – OVERALL SITEThe largest component in this area is bulk earthworks/site preparation cost of$28.2 million.
