Observation And Suggestions Rcc Works

The following suggestions are needed to be explored based on the performance that has been observed that during the yester pours being carried out M/s GDC and M/s SIL. 1. There is lack of proper and adequate coordination especially during transition of Day shift and Night shift. The persons in the night shift are leaving the site without proper reports / information which is must for performance evaluation and follow ups. It is therefore suggested that the concerned be instructed accordingly. 2. The need is imperative for spraying water onto aggregates in quest to control the temperature of concrete being produced at Batching plants .The fact is well known prior to start of pour but arrangements for spraying water are undertaken only after the start of pour. This creates huge time loss. It is therefore suggested that the concerned be instructed accordingly that adequate arrangements be made well in time before the start of pour so that time loss can be curtailed. 3. Ice is being added to water at Batching Plants therefore In charge of Site at Batching Plants be empowered to monitor the inflow of Ice depending upon the requirements coupled with ambient temperature. It is therefore suggested that the procedure be explored. 4. The available technical staff is not requisite to cater the requirement, it is felt that one technical person per Batching Plant be deputed at least during pours of such large volumes and where the temperature is to be controlled. It is therefore suggested that the deployment at Batching plants’ site of additional technical persons be explored on temporary basis. 5. It is observed that pour rate can further be improved. It is therefore suggested that the Minimum Concrete Production Capacity of batching plants’ shall be 120 M 3 / Hour and Concrete Placement Capacity at pour location shall be 100 M3/hour. Accordingly at least 17 Transit Mixers be deployed for the transit of concrete from Batching plants to pour location and hence availability of Transit Mixers at site for the pour be explored on temporary basis well before the start of pour. The efforts shall be exercised that %age utilization shall be at least 60 each, of both, Production Capacity and Placement Capacity.
