　　927.52 + 500+ 2 + 71.475 + 75.05 + 51.69+ 146.5 = 1774.24元/樘六、優化建議1、材料費優化a)不銹鋼板采購優化o當前不銹鋼板（0.8mm，304材質）單價為86.98元/m ，消耗量6.32m 。o建議：通過批量采購或更換供應商，將單價降至80元/m ，可節省：

　　927.52+500+2+71.475+75.05+51.69+146.5=1774.24 yuan/square meter. 6. Optimization suggestion: 1. Material cost optimization: a) Optimization of stainless steel plate procurement: The current unit price of stainless steel plate (0.8mm, 304 material) is 86.98 yuan/square meter, with a consumption of 6.32 square meters. o Suggestion: By bulk purchasing or changing suppliers, the unit price can be reduced to 80 yuan/square meter, which can save:

　　(86.98 - 80) × 6.32 ≈ 44.05元/樘。    b)減少膠類消耗量o萬能膠（3.20支/樘）和玻璃膠（1.48支/樘）用量較高。o建議：優化施工工藝（如采用點膠法），減少膠水用量10%，可節省：

　　(86.98-80) × 6.32 ≈ 44.05 yuan/unit.  B) Reduce the consumption of adhesive materials. The usage of universal adhesive (3.20 pieces/unit) and glass adhesive (1.48 pieces/unit) is relatively high. Suggestion: Optimize the construction process (such as using glue dispensing method), reduce the amount of glue used by 10%, which can save:

　　(3.20×19.50 + 1.48×6.19) × 10% ≈ 7.16元/樘。c)保護膜批量采購o保護膜單價2.00元/m ，可批量采購降低至1.50元/m ，節省：

　　(3.20 × 19.50+1.48 × 6.19) × 10% ≈ 7.16 yuan/unit. c) Bulk purchase of protective film: The unit price of protective film is 2.00 yuan/m, which can be reduced to 1.50 yuan/m for bulk purchase, saving:

　　(2.00 - 1.50) × 6.32 = 3.16元/樘。d)木方與細木工板替代o檢查是否有更經濟的防火材料（如輕鋼龍骨替代部分木結構），降低阻燃板基層成本10%，節省：

　　(2.00-1.50) × 6.32=3.16 yuan/unit. d) Is there a more economical fire-resistant material (such as replacing some wooden structures with light steel joists) that can reduce the cost of flame-retardant board base by 10% and save:

　　144.99 × 10% ≈ 14.50元/樘。2、人工費優化a)施工流程標準化o當前人工費合計500元/樘（打底160元+制安340元）。o建議：優化工序，減少工時15%，可節省：

　　144.99 × 10% ≈ 14.50 yuan/unit. 2. Optimization of labor costs: a) Standardization of construction processes. Currently, the total labor cost is 500 yuan per unit (160 yuan for base work and 340 yuan for manufacturing and installation). Suggestion: Optimize the process and reduce working hours by 15%, which can save:

　　500 × 15% = 75元/樘。b)工具升級o引入電動切割工具，提升剪板、折彎效率，降低加工成本20%，節省：

　　500 × 15%=75 yuan/unit. b) Tool upgrade: Introducing electric cutting tools to improve cutting and bending efficiency, reduce processing costs by 20%, and save:

　　(6.00 + 15.60) × 20% ≈ 4.32元/樘。3、加工與工藝優化a)批量加工折扣o剪板、折彎等加工費用（合計21.60元/樘）可通過集中加工爭取10%折扣，節省：

　　(6.00+15.60) × 20% ≈ 4.32 yuan/unit. 3. Processing and process optimization a) Batch processing discount o Cutting, bending and other processing costs (totaling 21.60 yuan/unit) can be negotiated for a 10% discount through centralized processing, saving:

　　21.60 × 10% = 2.16元/樘。b)減少鏡面處理成本o鏡面處理單價7.00元/m ，探索更經濟的拋光工藝或設備，降低至6.00元/m ，節省：

　　21.60 × 10%=2.16 yuan/unit. b) Reduce the cost of mirror treatment to 7.00 yuan/m  , explore more economical polishing processes or equipment, and lower it to 6.00 yuan/m  , saving:

　　(7.00 - 6.00) × 6.32 = 6.32元/樘。4、綜合費用優化a)規費與稅費合規優化o檢查是否符合某省小微企業稅收優惠政策，如增值稅率從9%降至6%，可節省：

　　(7.00-6.00) × 6.32=6.32 yuan/unit. 4. Comprehensive cost optimization a) Compliance optimization of fees and taxes o Check whether it complies with the tax preferential policies for small and micro enterprises in a certain province, such as reducing the value-added tax rate from 9% to 6%, which can save:

　　146.5 - (927.52 + 500 + 2 + 71.48 + 75.05 + 51.69) × 6% ≈ 32.76元/樘。b)管理費壓縮o通過數字化管理工具降低管理成本，壓縮管理費比例至4%，節省：

　　146.5- (927.52+500+2+71.48+75.05+51.69) × 6% ≈ 32.76 yuan/unit. b) Management fee compression: By using digital management tools to reduce management costs, the management fee ratio has been reduced to 4%, saving:

　　71.48 - (927.52 + 500 + 2) × 4% ≈ 14.30元/樘。

　　71.48- (927.52+500+2) × 4% ≈ 14.30 yuan/unit.

　　施后含稅綜合單價原含稅單價：1774.24元/樘

　　The comprehensive unit price including tax after implementation was originally 1774.24 yuan/unit

　　優化后單價：1774.24 - 203.73 ≈ 1570.51元/樘（降幅約11.5%）注意事項：1.替代材料需通過防火、強度等質量檢測。2.工藝改進需進行小規模試點驗證效果。3.供應商談判需確保長期合作關系穩定性。

　　Optimized unit price: 1774.24-203.73 ≈ 1570.51 yuan/unit (a decrease of about 11.5%) Precautions: 1. Alternative materials must pass quality tests such as fire resistance and strength. 2. Process improvement requires small-scale pilot verification of its effectiveness. 3. Supplier negotiations need to ensure the stability of long-term cooperative relationships.
