HomeMy WebLinkAboutApproach City of Winter Springs WTP No. 1 HSPS Suction Piping Replacement Prime Construction Group, Inc. (PCG) believes at the heart of all good construction project and/or work tasks is the right plan. The right plan includes planning for any/all variables to ensure that any project and/or work task is completed safely, on time and correctly the first time. For this job the City of Winter Springs is seeking PCG to provide the best price, best plan and best schedule to help the City maintain its high-quality water delivery to its residents with no interruptions of service. For the HSPS Suction Piping Replacement project to be successful open, direct, and constant communication will be necessary for all project stakeholders. PCG will focus on leading the stakeholder team during the life of this construction project and provide the labor, equipment and material necessary to complete this project as stress-free for all involved as we can. As we reviewed the suggested project phasing, it has become apparent that the City’s team and Carollo Engineers have come up with an engineered design that strikes a good balance of cost effectiveness with minimizing potential impacts to the customer. We would intend to follow the suggested phasing plan as showing the submitted project schedule. Not to minimize the other portions of this project, but for purposes of our project approach we will focus on the following to ensure the 4 critical overnight switchovers are constructed safe, on time and correct. For the 4 phases the following need to be adhered to: 1. Preconstruction – Test pit and verify all utilities for size and location. Special attention may be needed for utility relocations in conflict or adjustments to the proposed may need to be done. Once the variables of existing utilities have been identified that will allow us to prefabricate as much as possible ahead of the shut- down period to make the shut-down time as short as possible. Testing of all existing valves to ensure lines can be properly shut down for tie-ins. 2. Planning -- Once all variables are addressed and adequately planned for a meeting will be necessary to discuss the overnight shutdown plans and identify the best date and time to start. This will ensure that all stakeholders are adequately staffed for a successful overnight cut in and getting the plant back on- line as soon as possible. 3. Preparation of Site – Excavate, visqueen, dewatering pump set up, mobilize necessary equipment and back up equipment as needed for critical tie-ins. On the HSPS building work demolish openings and temporary shore masonry for pipe removal and replacement. All prefabrication started earlier complete prior to the night of execution. 4. Execution – Provide labor, equipment, lighting and material necessary for tie-in. Schedule extra labor, equipment and tools just in case needed due to unforeseen circumstances. Due to the sequencing of the design engineer the plant should be down in capacity only for 8 hours maximum. This will be accomplished by preplanning and executing the plan as identified above. Most of the risk in the job is in overall schedule and not necessarily plant operations. By the time the execution day is upon us all variables of risk should be removed. Items that can hurt the job in overall schedule is what is found in the preconstruction work. For phase 1 and 2 will there be any unforeseen underground utilities that will cause modification to the proposed pipe or relocation of existing that can delay the job. All 4 critical tie-ins rely on existing valves to close completely to ensure fast modifications to the existing piping systems. Testing of those valves prior to cut in is paramount and if additional line stops are needed you have to know that before you cut into the existing pipe. All of the risks aforementioned should be addressed before there is any chance of an emergency. Having a well thought out plan that will be owned by all stakeholders will ensure successful transitions during these 4 difficult transitions. PCG is committed to lead the stakeholders of this project in safe first-class quality project done on time. While we are on this project PCG will have an all hands-on deck approach if an emergency of any type pops up. We have over 70 employees that can be assigned to work tasks as necessary to ensure this project is treated as a preferential project for the City of Winter Springs.
