　　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)减少胶类消耗量o万能胶（3.20支/樘）和玻璃胶（1.48支/樘）用量较高。o建议：优化施工工艺（如采用点胶法），减少胶水用量10%，可节省：

　　(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)保护膜批量采购o保护膜单价2.00元/m ，可批量采购降低至1.50元/m ，节省：

　　(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)木方与细木工板替代o检查是否有更经济的防火材料（如轻钢龙骨替代部分木结构），降低阻燃板基层成本10%，节省：

　　(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、人工费优化a)施工流程标准化o当前人工费合计500元/樘（打底160元+制安340元）。o建议：优化工序，减少工时15%，可节省：

　　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)工具升级o引入电动切割工具，提升剪板、折弯效率，降低加工成本20%，节省：

　　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、加工与工艺优化a)批量加工折扣o剪板、折弯等加工费用（合计21.60元/樘）可通过集中加工争取10%折扣，节省：

　　(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)减少镜面处理成本o镜面处理单价7.00元/m ，探索更经济的抛光工艺或设备，降低至6.00元/m ，节省：

　　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、综合费用优化a)规费与税费合规优化o检查是否符合某省小微企业税收优惠政策，如增值税率从9%降至6%，可节省：

　　(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)管理费压缩o通过数字化管理工具降低管理成本，压缩管理费比例至4%，节省：

　　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.

　　施后含税综合单价原含税单价：1774.24元/樘

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

　　优化后单价：1774.24 - 203.73 ≈ 1570.51元/樘（降幅约11.5%）注意事项：1.替代材料需通过防火、强度等质量检测。2.工艺改进需进行小规模试点验证效果。3.供应商谈判需确保长期合作关系稳定性。

　　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.
