Potential Problems

Potential ProblemsWeather Along with all of the other health and safety risks on a construction, the weather can play a significant role in increasing the chances of an accident or incident occurring. The most obvious weather conditions which pose a danger are:Strong WindsTemperatureLightningHeavy RainFogPlan Errors Common design and detailing errors in construction arises due to either inadequate structural design or due to lack of attention to relatively minor design details.Change Order A component of thechange management process wherebychangesin the Scope of Work agreed to by the Owner, Contractor and Architect/Engineer are implemented.

Contractor ErrorsEquipment problemsDiffering Site Conditions Can cause schedule delays, cost increases, and dangerous working conditions, or invalidate design assumptions. Construction projects necessarily involve the assessment of site surface (and subsurface) conditions to select the best means and methods to develop a construction schedule and bid and to complete the project.Archaeological Finds

Problems MetWeatherOccurrences of adverse weather condition covering the months of June 2013 to January 2014 greatly affected the progress of work particularly the critical work items of the contract project.Due to the above concern, a contract time extension of 27 Calendar days to compensate the losses of time in executing the critical items of the contract was requested by the Contractor.

Rainy days hampered the field operation particulary in the delivery of item 200(Aggregate Sub-base Course) and Course and fine Aggregates for the box culvert and the PSCG Bridge.The number of rainy days at the project site had exceeded the built-in rainy days as per approved programmed during the preparation of the detailed engineering.Change OrderAn increase and decrease in the quantities of some items of work due to the revision of plans and introduction of Items of work that are not included in the original plan and necessary in the completion of the project to suit the actual field condition.

Archeological FindingsDuring the driven of H-Piles at abutment A, some piles refuses to penetrate the ground below the riverbed . In addition, only one pile meets the minimum penetration of more than 3.0 meters from the river bed elevations. They excavated the ground and found out that tip of these piles hit a solid rock which is 0.50 meter below the river elevation.
