Preconstruction Issues to Discuss
Several key issues should be discussed at a preconstruction meeting with the owners, design team, and contractor, including:
- Safety: What hazards will present themselves to the building residents, pedestrians, inspection personnel, and the contractor during the work, and what measures will be taken to ensure everyone's safety?
- Material approvals: What is the process of and timeframe for technical approvals? What is the process and timeframe of color and texture approvals? Will mock-ups and samples be required?
- Payment: How is the project funded? What approvals are necessary before payment can be made? What do the contractor, engineer and owner need to ensure payment is made within the time required by the contract?
- Schedules: How many phases are in the project? What is the sequence of the phasing? What will be the impact on the schedule if additional quantities, bad weather, or other unforeseen conditions appear?
- Communication: What is the desired communication flow? Should the contractor have a direct dialogue with the owner, or should the engineer deliver all communication? How will the building's tenants be informed of the project's progress? How will vital information, such as the availability of MSDS materials, be made accessible?
- Expectations: What does everyone expect? What are the inspection requirements? What testing will be necessary? Are there particular performance standards that need to be met? Does the engineer have in-house testing capabilities or will a third-party inspection be necessary? Who pays for testing? Who is to cut back the landscaping around the building? What happens if the sprinkler system is damaged when running a loader on the lawn?
Protection Plan Issues
When designing the protection plan of a high-rise project, make sure to include the following key issues:
- Building height: Consider how high the building is and how far falling materials can travels if a slight wind occurs. Is overhead protection needed for pedestrians to walk under, or can foot traffic be rerouted to safe areas away from the work?
- Sandblasting: If sandblasting is used to prepare steel or concrete surfaces, what protections will be necessary to prevent pitting of glass on windows or sliding doors? What medium should be used to sandblast with? How is the dust controlled?
- Air quality: Can people open their windows in areas within or near the work area? What happens if dust gets inside the units? Should the window perimeters and moving joints be taped and protected from dust intrusion? What happens if residents open their windows and break the protective seals? Who communicates to the residents?
- Vehicular traffic: Can the typical car or delivery traffic continue or should it be rerouted to prevent damage? If vehicular traffic must remain under the work area, what can be done to prevent damage and ensure safety?
- Pedestrian traffic: How close can people walk on the ground within the work area? What will be done to protect them? What signage will inform the public of the overhead work and direct them to safety?
- Other elements: How can we protect the roof, windows, doors, landscaping, and interior to ensure they are in the same condition as before the job started? How do we document the original condition of the building before the project has started?
