AM2017 1 AM2017 2 AM2017 3 Construction Site Layout and Design Site Management is the day to day on site control of a construction project. It is important to; Prepare the site for construction Keep with the time-scale of the budget Tackle any delays or problems Ensure quality and health & safety Coordinate communications between all parties involved in the onsite development and the public AM2017 4 Construction Site Layout and Design AM2017 5 Construction Site Layout and Design AM2017 6 Construction Site Layout and Design Site Communication ensures good; Information management Information distribution Plan utilisation Change management AM2017 7 Construction Site Layout and Design Site Security and Safety To avoid losses of materials and plant through theft and vandalism including careless behaviour To prevent fire on site To prevent injury and accidents To protect machinery and equipment (& property) To protect the public AM2017 8 Construction Site Layout and Design Construction Equipment Logistics ensures; Optimal use of material and construction work capacity Optimal use of machinery and equipment Minimization or reduction of waste Minimization of material movement AM2017 9 Construction Site Layout and Design Construction Site Layout Involves identifying, sizing and placing temporary facilities within the boundaries of a construction site. This temporary facilitates range from simple lay down areas to warehouses, fabrication shops, maintenance shops, batch plants, residence. Their areas are dependent on many factors including project type, scale of project, design, location and organisation of construction work. AM2017 10 Construction site Layout and Design Site layout is to be carried in on efficient manner An essential element of this goal is the planning of the site layout before the contract is started. (NB: No two sites are the same and perfect solutions do not exist). AM2017 11 Construction site Layout and Design AM2017 12 Construction site Layout and Design AM2017 13 Construction site Layout and Design Main items that must be considered in laying out a new site may be listed as follows: Access to site and “on-site” roads Storage of materials Temporary buildings for contract staff and other persons residents on site. Temporary services such as electricity, water etc. Fencing facilities AM2017 14 Construction Site Layout and Design Failure to plan a site layout in advance is a prime cause and increase in the overall cost of the project. Materials stacks will be wrongly be located double or triple handling material may be far from work areas Plant and equipment wrongly located For examples, concrete mixer is inaccessible for delivery of materials fixed cranes unable to reach all parts of works hoists with insufficient capacity or height. AM2017 15 Construction Site Layout and Design Inadequate space allowed where inadequate space for stocking of material or activities materials may be stocked on roads , causing hazards working areas may become too cramped or additional areas may have to be allocated with the consequences of time wastage. Site houses, may be located near noisy activities Noise machines, dusty conditions etc. Warehouses having inadequate space for loading and offloading. AM2017 16 Site Layout Planning Elements AM2017 17 Site Layout Planning Elements A well planned site leads to: Increased productivity and Safety Reduction in areas needed for temporary construction Maximisation of utilities and elements needed to obtain the above. Safety Fire preservation - fire is a major cause of damage to construction sites. Medical services – on a construction project a first aid kit is a must including PPE. AM2017 18 Site Layout Planning Elements Site Accessibility Easy accessibility will keep the morale of the equipment and vehicle drivers high, minimise chances of accidents and reduction of time wastage. Information signs Site map –should locate details of the project Traffic signs – traffic signs helping guidelines sites on large projects and avoiding accidents. emergency AM2017 19 Site Layout Planning Elements Security It is necessary to have a proper guard entrance to the site and also important to keep track to all visitors to the project. entrance lighting fencing Accommodation On large construction projects, it is necessary to provide camp accommodation for all types of staff involved in a project. Offices Offices should be on/close to the site and in a safe area. The offices should be provided with proper office equipment. AM2017 20 Site Layout Planning Elements Water supply and sanitation It is necessary to have water and toilet facilities on site (statutory requirements) Material handling A third (⅓) or more of all cost operation can be classified as material handling. Proper planning will result in direct cost and time savings. AM2017 21 Site Layout Planning Elements Storage and site cleaning It is necessary to plan and reserve storage of materials so that multiple movements are avoided. e.g. lay-down areas. Lay-down areas- reserved for large materials and equipment (this is for short term or long term). Warehouses - normally used for rainfall/moisture free materials where they are stored until they have been distributed to the job AM2017 22 Site Layout Planning Elements Craft change houses – these provide shelter and space for craft personnel. Batch plants and fabrication shops- are provided in projects where its more economical to produce concrete or do fabrication on site. AM2017 23 Temporary Facilities Characteristics These entail or ensuring that the site meet the following requirements; Satisfying environmental and safety regulations All temporary facilities should satisfy environmental and safety regulations. Special attention should be paid to temporary facilities like batch plants which have high pollution potential. Availability of diverse solutions for the same problem. e.g. Rent a building near the site if there existing facilities or plan ‘just-in- time’ delivery. AM2017 24 Temporary Facilities Characteristics Relatively short time span for a specific location The life span of temp-facility depends on the duration of the project. In general it must be removed as soon as the project is completed. Reutilisation with a minimum loss for temporary facility or modified function at another location Easy of assembly, dismantling Prefabricated modules are ideal for constructing temporary facilities and they are usually easy to assemble and dismantle. AM2017 25 Temporary Facilities Characteristics Standardization of design This approach makes the maintenance of transportation and storage of temporal facilities easy. Standardization of design and construction of temporary facilities can increase the frequency of re-utilization and reduce the work-hours and cost required for constructing the facilities. AM2017 26 DESIGN: Facility Identification and Sizing Temporary Facilities Selection One of the characteristics of temporary facilities is the availability of diverse solutions. Considerations when selecting the required temporary facilities for a specific project are: Construction type: The construction of an industrial plant, such as power plant, requires more storage and fabrication area for process mechanical and electrical work than other projects such as a highway project. AM2017 27 Facility Identification and Sizing Type of Contract For example, in a turn-key contract, the contractor can consolidate the administrative and construction operations, means that fewer but larger and more efficient temporary facilities can be selected. For different contracts e.g. management contract, this will translate into a higher number of smaller temporary facilities serving each individual contractor. AM2017 28 Facility Identification and Sizing Project size: A relatively small project can be managed from a trailer or portable structure. While a five to ten year project may need temporary facilities of a more permanent nature. Project location: Projects located in uninhabited regions or in places where skilled labor is scarce require additional facilities for eating and living. Project far from industrial centers require on site services such as batch plant, equipment maintenance shops, long term storage area, and recreational centers for the families.
