Requirements for Interior Fit-Out Construction
Among all residential construction items, the interior fit-out is an extremely important task. This work requires seamless coordination between construction teams, ensuring that tasks do not overlap, are completed on schedule, and still maintain the aesthetic integrity and technical specifications of the initial design.
The materials and equipment used during the construction process must strictly adhere to the drawings and meet quality commitments, while the pricing must be reasonable. If any changes are necessary during the construction, they must be agreed upon with the investor before being implemented.
Throughout the construction process, inspection and supervision must be performed regularly to ensure adherence to the schedule, quality, and aesthetic standards of the project. If any errors are discovered, timely corrective measures must be implemented.
After the completion of construction, maintenance and upkeep must be carried out to ensure the project functions well and maintains its durability. Interior components need regular maintenance and cleaning to preserve the beauty and quality of the final work.
