We value the project timeline and will communicate it clearly with you. The total project duration will vary depending on the complexity of the project, the size of the space, and the client's confirmation process . Generally speaking: • Residential projects: typically take 2 to 4 months . • Office projects: typically take 1 to 3 months . Rest assured, after signing the contract, we will provide you with a detailed project schedule and report to you regularly to ensure the project progresses smoothly.

• Initial Communication and Preliminary Estimate: After understanding your project's basic requirements, we can provide a free preliminary estimate range for your reference. • Detailed Design and Accurate Quotation: To ensure the accuracy of the quotation and the completeness of the design, after both parties have expressed initial willingness to cooperate, we will conduct a paid on-site survey and detailed design drawings based on in-depth discussions of needs. This fee will be fully deducted from the formal engineering contract signed later, aiming to ensure that both parties' time and investment can be focused on truly meaningful projects.

• Client cooperation: You need to assist us in communicating with the building management office to obtain construction permits, confirm the design and material selection in a timely manner, and conduct phased acceptance and payment according to the contract milestones. • Quality assurance measures: 1. Dedicated personnel: Your project will be managed by a dedicated project manager throughout the entire process to ensure smooth communication. 2. Phased acceptance: We will invite you to conduct on-site acceptance at key project milestones (such as after the completion of water and electricity work and masonry work) to confirm that everything is in order before proceeding to the next phase. 3. Clear Warranty Period: We offer clear engineering warranty terms, so you can move in without any worries.
