EGB382 (Week 4)
Site Establishment & Management
| Question | Answer |
|---|---|
| Development of Site Facilities | • Understand the Project Scope and work activities involved (Work Breakdown Structure) • Access • Site Construction Facilities • Site Buildings • Site Utilities |
| Understanding Project Scope (1) | • Assess volumes of major materials to be moved or acquired • Assess the weights and dimensions of major permanent and temporary works components that may need to be transported, lifted or handled in some way |
| Understanding Project Scope (2) | • Assess time available for each major activity to determine an approximate rate of progress required • Build safety factors into assessment (e.g. size borrow pit/quarry–may need to yield about 200% of calculated volumes in place) |
| Site Access | • Existing Public Roads • Other Access Roads • Site Haul Roads • Site Light Vehicle Roads |
| Existing Public Roads (1) | • Owned by Local Shire/Council or State or Federal Government • Rules for Operating on State or Federal Government Roads • Arrangements for Operating on Local Shire/Council owned roads |
| Existing Public Roads (2) | • Payment for Upgrades • Maintenance Agreements (Damage and repairs undertaken by the contractor – Proof of causation) |
| Other Access Roads - Key parameters (1): | • Safety • End use of road (or restore area to previous condition) • Availability of construction materials • Pavement strength, type, width |
| Other Access Roads - Key parameters (2): | • Value for Money (VfM) construction (temporary or permanent) • Environmental requirements • Available time to construct |
| Site Haul Roads - Key parameters (1): | • Safety • Match size and economical performance characteristics of major haulage units • Constructible given the site topography |
| Site Haul Roads - Key parameters (2): | • On major projects, designed to avoid or overcome mixed fleet performance issues • Must be designed to meet requirements of area they are servicing |
| Site Haul Roads - Key parameters: | • Pavement strength • Availability of construction materials • Environmental requirements / restrictions • Cost |
| Site Light Vehicle Roads - Key parameters: | • Safety • Volume • Vehicle types • Sight distance, horizontal and vertical alignment • Pavement types • Availability of construction materials • Environmental requirements • Cost |
| Plant – Construction Facilities on Site (1) | • Will you loose control of your program if key materials supply is left in the hands of others? • If so – is there a readily available cost effective ‘Plan B’ for off-site supply? |
| Plant – Construction Facilities on Site (2) | • Are there adequate sources of raw materials on-site or within the vicinity? |
| Plant – Construction Facilities on Site (3) | • Are rates quoted competitive or better than what you can achieve by installing and operating temporary facilities on site? • Are there sufficient areas on site available to install facilities or can they be developed at reasonable cost? |
| Type of Facilities (1) | • Quarry, crushing plant, sand extraction plant • Stockpile areas and Spoil dumps • Laydown areas • Plant storage area • Workers parking area |
| Type of Facilities (2) | • Runoff and sedimentation control devices • Areas for temporary buildings (Offices, first aid facilities, store, workshops, crib sheds, training facilities, ablutions etc.) |
| Site Buildings - Offices (1) - Use Work Breakdown Structure activities to determine the total number and categories of people required including: | • Contractors Staff (Management, Project & Site Engineers, Contract Administrators, Administration Support, Superintendents & Supervisors) • Design staff and communications with site team |
| Site Buildings - Offices (2) - Use Work Breakdown Structure activities to determine the total number and categories of people required including: | • Owner staff and Owners Contract Administration Staff (requirements normally advised in tender documents) • Is co-location proposed or in separate buildings? |
| Site Buildings - Other | • Small area offices for Supervisors • Crib (lunch) sheds • Ablutions blocks • First aid buildings • Store • Workshop • Generator sheds |
| Camp or not to Camp? (1) | • Availability and skills of local workforce • Accommodation available within reasonable travel time to site • Requirements specified in current industrial awards |
| Camp or not to Camp? (2) | • FIFO option • Possible camp location in relation to work site, nearby townships, required utility services etc |
| Camp or not to Camp? (3) | • Expectations of local indigenous workers especially on projects overseas • Recognition of any cultural differences • Type and number of recreation facilities required |
| Camp or not to Camp? (4) | • Married or single staff accommodation required • Other facilities – Medical centre, shop, post office, wet canteen, school, sports facilities etc |
| Site Utilities - Site utilities required will include: | • Electricity • Water • Sewerage disposal • Telecommunications • Site radio • Waste disposal |
| For required site utilities such as: • Electricity • Water • Sewerage disposal • Telecommunications • Site radio • Waste disposal | In each case, the question to be answered is are these services readily available from a service provider or do we have to install them as part of the project? |
| Cranes and Hoists - General Considerations | • Weight and size of load involved • Height of lift • Obstructions to lift over (walls, etc) • Distance to item to be lifted • Utilisation factor (how many hours per day/week used) • Whether lifting operation can be static (i.e. fixed crane) |
| Cranes and Hoists - Further Considerations | • Access – type of ground over which the crane may travel • Radius of swing • Amount of lateral movement • Whether luffing will be required • Type of plant being used in conjunction with cartage, e.g. concreting plant |
| Cranes near Excavations (1) | • To avoid the possibility of a ground failure, the crane must be set up on outriggers with proper cribbing |
| Cranes near Excavations (2) - Using the following rules, one can determine the proper distances needed for a safe lift: | For stable ground (stable rock, moist clay (Type A), etc.) conditions, the standard procedure positions the crane away from the excavation or trench, a distance equal to at least 1.5 times the depth of the trench |
| Cranes near Excavations (3) - Using the following rules, one can determine the proper distances needed for a safe lift: | In situations where the ground consists of loose soil, fresh back fill, sand, or crushed rock, the distance from the trench or excavation should be at least 2 times the depth of the excavation |
