The last edit to this post was made by Desert Fish on 2015-10-28 at 06:55. I’ve gathered some questions from this year’s First-Class Constructor exam, along with their answers. I’m sharing them here to encourage more people to participate. Instead of posting all the questions at once, I’ll present a few multiple-choice questions or one case study at a time, with the answers hidden. The answer will be available after responding. Everyone is welcome to participate; those who give correct answers will receive a reward from the moderator. ****************************************** 31. For the earthwork work of a certain construction project, manual excavation and transportation as well as mechanical transportation are used. The quantity of earthwork specified in the tender’s bill of quantities is 2000 m3, while the bidder calculates that the actual amount of earthwork that needs to be excavated is 3800 m3. The costs associated with manual excavation are estimated at 42,000 yuan, the cost of manual transportation at 15,000 yuan, and the cost of mechanical transportation at 38,000 yuan. The management cost represents 14% of the total cost of labor, materials, machinery, and other expenses. Profit is set at 8% of the total cost of labor, materials, machinery, management costs, and other expenses. In accordance with the \"Code for Valuation of Construction Works Based on Bill of Quantities\" (GB50500-2013), without considering other factors, what is the comprehensive unit price per m3 for earthwork as quoted by the bidder? A.33.41 B.58.48 C.61.56 D.73.10 Answer: B 【Expert Explanation】This question tests the calculation of comprehensive unit prices; since the bases for calculating management fees and profits are provided, the difficulty is not high. Management fee = Total cost of labor, materials, and machinery × Management fee rate = (42000 + 15000 + 38000) × 14% = 95000 × 14% = 13300. Profit = (Total cost of labor, materials, and machinery – Management fee) × (95000 – 13300) × 8% = 8664. Comprehensive unit price = (Total cost of labor, materials, and machinery + Management fee + Profit) ÷ Quantity of work specified in the schedule = (95000 + 13300 + 8664) ÷ 2000 = 58.482/m3. Refer to page P234.32 of the textbook. For a certain construction project, the advance payment is 1.2 million yuan. The contract stipulates that the monthly progress payments shall be made at 80% of the settled amount ； A payment of 200,000 yuan per month is made for safe and civilized construction ； The advance payment is recovered in equal installments over 3 months, starting from the 4th month of project commencement. The settlement amounts for the first 6 months after commencement are as shown in the table below; therefore, the amount payable in the 5th month is [X] ten thousand yuan. A.136 B.160 C.156 D.152 Answer: C 【Expert Explanation】The payment amount = settlement amount × payment ratio + cost for safe and civilized construction – amount deducted from the advance payment = 220*80% + 20 – 120/3 = 1.56 million yuan ；
31. For the earthwork works of a certain construction project, manual excavation and transportation as well as mechanical transportation are used. The quantity of earthwork specified in the tender’s bill of quantities is 2000 m3, while the bidder calculated the amount of earthwork that needs to be excavated as 3800 m3. Considering the cost of removing the soil and transporting it away, the bidder’s estimated cost for manual excavation is 42,000 yuan, the cost for manual transportation is 15,000 yuan, and the cost for mechanical transportation is 38,000 yuan. The management cost is 14% of the total cost of labor, materials, machinery, and equipment. The profit is set at 8% of the total cost of labor, materials, machinery, equipment, and management costs. In accordance with the \"Code for Valuation of Construction Works Based on Bill of Quantities\" (GB50500-2013), without considering other factors, the bidder’s quoted comprehensive unit price for earthwork is (B) yuan/m3.
