Chapter 1548: No need to hesitate

"The first thing we need to build is a waterproof breakwater dam with a circumference of 55 kilometers." Lin Yichong, who has done enough homework beforehand, spoke unhurriedly: "Considering that this is a permanent building, we plan to use waterproof Reinforced concrete construction, the dam is 10 meters high, of which the underwater part is 4 meters, the water part is 6 meters, and the thickness is 2 meters. The total volume of the dam is 1.1 million square meters, the density is 2.5 tons/square, and the total weight is about 2.75 million tons. All building materials All need to be sent from the mainland. If the 300,000-ton freighter planned by Dr. Tan is transported, 9 round-trips are required. Considering the redundancy, we will calculate the 10 rounds and complete the construction of this dam according to our current construction technology. Approximately, the construction period will be about one year. We have initially estimated that the cost of the dam will be 36 million per kilometer, and the total cost will be about 2 billion."
Tan Zhenhua secretly calculated in his heart that he felt that the general manager Lin didn’t want to ask for a high price. The cost of 36 million per kilometer is slightly higher than that of the Shanghai-Nanjing Expressway under construction in China. Considering the location of this project The location and difficulty of construction are still acceptable.
Seeing Tan Zhenhua nodded slightly, Lin Yichong felt a little bit calm. He was afraid that the first investment amount would scare people, but now it seems that this person is really rich and has a quotation of 2 billion yuan. , He didn't even frown.
"After the dam is built, the next task is to drain the seawater in the lagoon." Lin Yichong continued: "According to the requirement of Dr. Tan that domestic equipment must be used, we conducted a nationwide survey some time ago and learned that The largest domestic water pump that can be manufactured at present is 1.6 meters in diameter, and each has a drainage capacity of 20,000 cubic meters per hour. If 100 pumps are installed and kept in continuous operation for 24 hours, 48 ​​million cubic meters of seawater can be discharged a day. According to preliminary calculations, There are about 1.95 billion cubic meters of seawater in the lagoon, which is expected to be drained in 40 days. Considering the influence of unforeseen factors such as calculation errors and temporary equipment troubleshooting, the construction period is tentatively set at 60 days. According to our cooperation with the water pump and diesel generator manufacturers As a result of preliminary negotiations with the fuel supply department, the total cost of purchasing 100 water pumps and auxiliary equipment, power supply and fuel will cost about 300 million yuan."
Tan Zhenhua nodded again. This situation is similar to what he has learned. The equipment purchased for 300 million yuan is not a one-off. In fact, there are still many places to use these things next.
"Next is the most expensive part of the whole project." Lin Yichong continued: "That is the excavation and filling of earth in the lagoon."
"In this phase of construction, the main design expenses are as follows:
1. Purchase of vehicles and equipment: 1,000 heavy-duty trucks of 100 tons need to be purchased. Calculated with an average density of 2.5 tons per square meter, each vehicle can transport 40 cubic meters of earth and stone at a time. The average transportation distance is 4 kilometers per trip and 8 kilometers back and forth. The vehicle speed is 30 km/h as the benchmark data. It takes 16 minutes on the way, plus 3.2 minutes for loading and unloading soil and rock. It takes 19.2 minutes to complete a trip. It can transport 75 trips in 24 hours a day. 1,000 vehicles can transport 3 million cubic meters of soil and rock a day. Two billion earthwork needs to be transported and it takes 666 days. Taking into account various unforeseen factors, the construction period of this section is set at 30 months.
In addition to trucks, in order to meet the construction needs, it is necessary to purchase 200 excavators, 50 earth-drilling and rock crushing machines, and 50 road rollers, totaling 1,300 various engineering surveys. According to Dr. Tan's requirement that domestic products must be used, we will adopt a bidding method to purchase domestic brand products, but considering that domestic construction machinery is still far behind imported brands in terms of failure rate and durability, according to Past experience, in actual construction, we will calculate the actual construction of the vehicles and machinery involved in the actual construction at an attendance rate of 80%, so that 20% of the procurement redundancy must be increased, and the total procurement of construction vehicles will require 1,560. Preliminary estimates show that the average unit price of this type of construction vehicle is 1 million yuan, and the total vehicle purchase cost is about 1.56 billion yuan. In addition to other vehicles and equipment necessary for construction, the project budget is 2 billion yuan.
2. Fuel consumption: According to the data just now, the heavy-duty vehicle is fully loaded and goes back to the empty vehicle. It takes 8 kilometers to go back and forth. According to the average fuel consumption of 2 yuan/km, it is delivered 75 times a day, and 1300 vehicles are on duty every day. Stone machines and road rollers are also calculated based on the same fuel consumption). The fuel consumption per day is about 1.5 million yuan, the entire construction period is about 900 days, and the fuel consumption is 1.35 billion yuan.
3. Labor costs: Considering that the situation around Huangyan Island is not very stable, we will pursue maximum construction efficiency. In order to catch up with the construction period, the construction site will implement three shifts a day and an 8-hour work system. Therefore, 1300 vehicles require 3900 drivers. Others There are 1,100 construction personnel, a total of 5,000. Taking into account the objective environment difficulties faced by the construction personnel, higher wages and bonuses must be given. Therefore, it is estimated that the entire construction period will cost about 1 billion wages, bonuses and other personnel expenses. To meet these 5,000 people For a long-term life on the island, another need to prepare at least 50 million yuan in food purchase expenses.
The above three items total 4.4 billion yuan. "
The sum of wages and bonuses for 5,000 people for 2 and a half years is 1 billion, which is equivalent to the average labor compensation of 200,000 yuan for each worker involved in project construction. This was a considerable amount in China in the early 1990s. After all, Tan Zhenhua remembers clearly that in another time and space, at that time, a dignified master's degree graduate could only get a salary of 700 or 800 a month, and he barely even had a salary plus bonus for a year. If you can round up a whole number, that’s it. In Ningdu City, it is already a proper high-income class. Now I am paying 80,000 yuan a year to find someone to work on Huangyan Island. It is estimated that people who want to try to change bicycles to motorcycles should There are quite a few.
Lin Yichong's explanation continues: "After the lagoon is filled, some facilities on the island need to be reinforced, and some basic supporting facilities must be built.
The main areas that need to be reinforced are the dams of freshwater lakes and inland seas. Calculated according to the narrow and long shape of 2 kilometers wide and 5 kilometers long, the total length of the lake dykes is 14 kilometers, and the port dams in the southeast are 18 kilometers, totaling 32 kilometers. The construction standards of these dams can be slightly lower than that of the outer wave breakwaters, including the large-scale dock facilities built in the port, and the estimated cost is 2 billion yuan.
The airport is the main transportation hub facility of New Huangyan Island. According to Dr. Tan’s requirements, the airport must meet the
An 124
standard that can take off and land. Therefore, it will be constructed in accordance with the national standard 4F level. Two runways of 3,600 meters will be constructed. The construction cost of the terminal building, two freight stations and a ground transportation center will cost about 1.5 billion yuan.
The island will build 15 vertical and 15 horizontal roads with a total of 300 kilometers. At a cost of 1 million yuan per kilometer, 300 million yuan will be needed.
The budget for the construction of rainwater collection and sewage pipelines is 100 million yuan.
The budget for the construction of two thermal power plants and the power grid is 200 million yuan.
Construction of sewage and garbage treatment plants: 100 million yuan.
According to the target proposed by Dr. Tan, the island’s forest coverage rate is 50%, and 50 square kilometers of trees need to be planted. Calculated by planting 100,000 trees per square kilometer, a total of 5 million trees need to be planted at an average cost of 200 yuan per plant. 1 billion yuan is required.
In order to ensure the growth of forest trees and crops, soil needs to be transported from the mainland to cover the planting area. To spread 30,000 mu and 20 square kilometers of arable land to a thickness of 0.5 meters, 10 million cubic meters are required; in addition, each tree is paved during afforestation One square meter in size and 0.5 meter thick soil requires 2.5 million cubic meters. The two items total 12.5 million cubic meters, and the cost is 625 million yuan to be shipped from the mainland at a cost of 50 yuan/square.
According to the soil density of 1.5 tons/m3, the total weight of the 12.5 million cubic meters of soil is 18.75 million tons. It requires a 300,000-ton ship to transport 63 trips. Based on the voyage, each trip will take 7 days and a total of 441 days to complete. With redundant time, the transportation work is expected to be completed within 18 months. Of course, this work can be carried out simultaneously with the previous excavation and filling work.
These projects total: 5.825 billion yuan.
After the construction of these projects is completed, ship locks can be installed on the waterways that communicate with the internal and external seas, the closures of the waterways can be blasted, and the final dredging can be carried out. Due to the large volume of this shiplock, the estimated construction cost will also cost 100 million yuan.
In addition, it is necessary to build administrative buildings, schools, hospitals, hotels and other public facilities and infrastructure on the island. Combining all these investments, we estimate that the main project construction will be completed and a total of 14-15 billion will be invested. In this case, the construction period is about 5 years. "
15 billion yuan, at the current exchange rate, less than 2 billion US dollars, you can create a brand-new Huangyan Island!
Tan Zhenhua feels that there is no need to hesitate at all!
