Project Planning and its significance

1. U18CE606 CONSTRUCTION MANAGEMENT & EQUIPMENTS Preliminary Project Planning

2. Introduction Preliminary Project Planning: Site layout, Infrastructure development - Security, Office and Residence , Power , Water, Access roads, Drainage, Illumination, Storage yards, Workshop, Garage, Parking , Testing facilities, Medical care, Firefighting facilities, Communication and fuel station facilities Construction work cannot be started without adequate preparation, such as acquisition of land, collection of comprehensive information / data required for design work, and preparation of specifications and contract documents. Enough land should be acquired for project work as well as for building infrastructures for executing agencies to complete their contractual obligations safely maintaining quality without time overrun. Construction method should be adopted keeping all these in view to ensure assured quality output. Project implementation different kinds of materials conforming to the detailed specifications are required.

3. Site layout Acquisition of land is a prerequisite for starting construction activities. The acquired land must be sufficient to meet the requirements of both the project layout as well as the construction agencies. A construction agency would need sufficient land for constructing their temporary offices, covered stores, open storage yard, space for pre assembly, storage areas for spare parts, mountings, movement, garaging of construction offices, workshop facilities etc ., For initiating preparation of project layout by owners and working out schedule of items for competitive bidding by interested construction agencies, the following information should be gathered by visiting the actual location where construction work is to be executed. Site location Accommodation Services Records Man power Materials Sub-Contractors Applicable local laws, taxes and service charges etc.,

4. Site layout Site layouts of construction agencies should be prepared keeping in view economy, efficiency and security. Avoiding double handling, easy accessibility and short movement / hauling would economize construction activities. Availability of materials and equipments as and when required is essential for both economy and efficiency. Security deserves prime consideration for avoiding loss by theft or vandalism. This can be best be done by fencing along the boundary of the allotted space and posting security g uards. The layout of the project should be developed keeping in view the extent of mechanization contemplated.

5. Infrastructure development Once the Detailed Project Report (DPR) has been prepared and sanctioned by the appropriate authority, necessary fund should be made available for building up infrastructures to facilitate project implementation Assignment of site personnel is the first step that should be taken towards initiating implementation process. Acquisition of land must be completed before assignment of site personnel, mainly because delays on any account whatsoever would only escalate the project cost . Speedy and timely project implementation would not be possible without having the following infrastructures ready Boundary wall Office and residential accommodation Electrical power Water

6. Infrastructure development Roads Drainage facilities Yard illumination Cement sheds and storage yard Workshop, garage and parking facilities Testing laboratory Medical facilities Fire fighting facilities Communication facilities Diesel and petrol filling station

7. Security Security at the site is to be very strict to ward of loss by pilferage , theft and vandalism. Necessity of boundary walls along the periphery of a site with strong steel gates at the crossing of roads and railway tracks. Security guards should be posted to check entry and exit of personal vehicles. Arrangement of accommodation would be depend on the exact site location and existing accommodation available nearby. If the site is located in remote and isolated area, new accommodation would have to be build . Office accommodation can built in 2 phases: Temporary offices and Permanent offices Temporary structures normally dismantled when vacated. Office and residence

8. Power The DPR contains an estimated requirement of unit wise as well as total electrical power for project. First need workout load demand during implementation process. On the basis of estimated load, an application is addressed to the government agency or private enterprise responsible for distribution of metered power at the project site . Like power , demand of both portable and construction water requirement could be worked out. Water would be required for: Construction activities Concrete production Masonry work Portable and construction water Curing of concrete Soil compaction Human consumption Drinking Sanitation

9. Access roads Movement of heavy transport vehicles and construction equipment would need firm base . Water logging at the site may disrupt the progress of construction activities to a great extent. Arrangement of both rain water as well as waste water should be made from the beginning. It is important for : Extending working period beyond daylight hours Security Safety measures And the yard illumination also helps avoidance of loss by theft and vandalism. Drainage Yard illumination

10. Storage In the construction industry it is essential that storage of materials and equipment is considered for the entirety of the project. This includes bricks, sand, power tools as well as larger machinery This means that warehouse storage plays an integral part in the construction industry, and without proper storage a lot of problems can occur and impede on the operation. There is different types of storage facilities are: Out door Indoor Semi indoor

11. Workshop, garage and parking For time bound implementation of a large project , mobility is very important. If workshop is envisaged in any project, it should be built on topmost priority so that it can be utilized during implementation stage . A project layout would always call for provision of covered garage spaces , mostly as apart of the office building. Parking facilities should be available for visitors, vehicles and also planned for mobile construction equipment during off duty hours . Each construction project determines its own individualized testing needs A variety of factors influence the type of testing required. Among these factors are size of the structures, terrain, type of soil and subsurface conditions at the construction site and other conditions peculiar to the specific location Hydraulic tests and leak tests are carried out in situ For the construction of roads and highways, contractors are required to set up full fledged laboratories in remote areas Testing facilities

12. Medical care Making provisions prior to the start of the construction project for prompt medical attention in case of serious injury. Readily available first aid supplies If a government fire station is located near by, then firefighting planning should done in construction with them.(insurance agency is also apart in this planning) Adequate water should always be available at the project site round the clock. Also buckets filled with sand or water should also be kept at venerable points so that those who cannot use fire extinguishers can use the contents of buckets for fire mitigation . For movement of people For construction equipment and machineries For diesel generators Fire-fighting facilities Fuel filling station

13. Communication f acilities Quick and efficient communication facilities should be available at the project site so that there is no communication gap between the top management and the project site management Internet facilities Land line phones Courier facilities

14. Outcomes Student will be able to understand what are the factors to be considered before preparing site layout . Student can able to develop infrastructure facilities in construction site. Questions for reference How should requirement wise total areas be worked out during land acquisition ? What kind of storage facilities should be available at a construction site? What is the first step towards the implementation of a project work?
