1 Division 2 Site Work Estimating Tips Swing angle of equipment - Ideal is 45 degree, for 90 degree swing efficiency could reach to 020 Sub-surface Investigation & 80% while for 120 degree it may reach 70%. Demolition Estimator shall obtain all available information concerning soil type. A site investigation is mandatory to reveal all site conditions, looking in particular for hazardous waste, stream beds, prior dumping, site restrictions and access, flood plains and all other factors that would strongly influence construction methods and costs. As any ground penetration has some risks, test pits, and knowledge gathered tend to control such risk. Demolition usually is executed by speciality contractors if explosives method is involved. Estimator shall consider in costing building demolition all factors that may affect the cost such as work space, rubbish handling, temporary bracing or shoring, dust control, security measures, hauling distance and costs of any required permits. Cut Depth: Choose the proper equipment to do job accordingly. Soil Type: Items in the book highlights this factor, Ideal equipment efficiency is for a sandy soil, if the soil is sand and gravel equipment efficiency is reduced to 90%, while efficiency could be as low as 20% for a poorly blasted rock. Degree of Equipment Operation: Time of equipment service, operator activity, weather factors, project restrictions, etc.. are some key factors affecting efficiency. Stockpile Distance and length of drag as well as maneuvering conditions. Site topography and volume of work Excavation management planning. Others such as specification control requirements, actual slope requirements, distress means and maximum allowable slope and slope configuration requirements. All productivity rates in this book are based on a bank measure. 021 Site Preparation & Excavation Support 025 Paving & Surfacing Site visit will determine the extent and scope of Good management planning for placing the base work required for the site preparation.

Contractor must always fencing or increase the number of guards. keep an easy access to different parts of site, material flow and labor movement to maintain 022 Earthwork good productivity. Contractor shall carefully As there are many factors that affect productivity study the site topography, buildings distribution, rates of earthworks, no productivity rate shall be planned utilities & investigate all discrepancies considered as 100% accurate. This book that may affect productivity and costs. includes many items concerning earthworks in different types of soils as well as different type 029 Landscaping of equipments.

Estimator project, because of different plants specified to be shall choose the proper economical piece of planted in different seasons. Contractor must equipment having best efficiency verses lower consider all types of plants specified, scheduled cost. Estimator shall be aware of the following planting plan, needed maintenance time, staff factors that affect equipment efficiency, and watering requirements during the construction productivity and costs. period.
