103 kilometers, 15 billion euros! China Railway and China Communications will jointly build the world's longest undersea tunnel

Finnish-estonian company FinEst Bay Area Development said it will collaborate with China Railway International, China Railway Group and China Communications Construction to jointly design and build the 103-kilometer-long Tallinn Helsinki undersea tunnel. When completed, it will be the world's longest undersea railway tunnel, allowing tens of thousands of visitors to travel about 20 minutes instead of two hours by ferry.

The governments of Finland and Estonia have been considering linking their capitals for years because the two countries are separated by the Gulf of Finland, making travel difficult. In 2016, Finland and Estonia signed a cooperation agreement to build an undersea railway tunnel, which was originally planned to be 92 kilometers long and cost about 12.5 billion euros (about 94.1 billion yuan). However, the length of the tunnel has been increased to 103 km, and the project budget has also increased.

Chinese companies not only contribute money, but also bring the most advanced technology in the world. As Finland and Estonia's expertise in tunnelling and high-speed train technology was not enough to support the undersea tunnel, new partners were needed. The super-strong combination of China Railway International, China Railway and China Communications Construction has been officially certified.

35,000 people participated! The largest transportation infrastructure project of the China-Pakistan Economic Corridor has been completed

On July 23, the National Highway Authority of Pakistan issued the certificate of substantial completion of the Sukur to Multan section of the Peshawara-Karachi Highway to China Construction, marking the early completion of the largest transportation infrastructure project of the China-Pakistan Economic Corridor.

At the peak of the project construction, the participants included more than 1,800 Chinese employees, more than 4,300 soldiers and policemen, and more than 28,900 Pakistani employees, forming a "super large corps" joint combat team.

The construction of the project requires 88.12 million cubic meters of earth and rock, 15 million cubic meters of asphalt concrete, more than 170,000 tons of materials to be entered and transferred every day, and 103,000 kilometers of 1 meter ×1 meter wall can be built around the earth's equator 2.5 times.

The project imported 1181 sets of machinery and equipment from China, such as 1132 dump trucks, 169 loaders, 140 excavators, 116 graders, 254 road rollers, 452 local rental equipment and more than 2900 appliances.

The project construction uses Chinese technology, introduces Chinese equipment, shows Chinese wisdom, and becomes another representative project of "built in China" on the "Belt and Road".

The accumulation and application of construction project cost data - let the basic data take root and let the result data speak

China's annual investment in infrastructure construction funds of about hundreds of thousands of billion yuan, accompanied by huge investment has produced a large number of structured and unstructured engineering cost related data, the scale of historical data is about 100TB~300TB, the annual new project data about 150TB. Making good use of these data in the era of big data has become a key point.

Solve the problem of inaccurate content of quota to make the quota rooted

The reason why the cost management department can not give a convincing reason is mainly that the current quota preparation method is calculated on the original basis by the experts in cost with their personal experience, so there will be a gap with the reality; In addition, the cost management institutions at all levels are basically revised once every 5 years, because the revision cycle is relatively long, the timeliness naturally lags behind.

Therefore, it is necessary to change the way of thinking, let the quota come from the market, and then return to the market, and collect various types of construction project cost data through information technology, which represents the actual consumption of enterprises in the construction process or consumption expectations.

Let the price information of the talent machine be more accurate so that the market information price takes root

The cost management agency obtains the information through the active collection of information agents and the reporting of market material production units or dealers. Limited by the number of corresponding personnel and the limitation and one-sidedness of the information source, the price information released is inaccurate and incomplete, and the actual demand of the market is greatly different.

The use of information technology means to collect and analyze prices, and take this price information as the basis for calculation, so that the material price information generated is rooted and traceable, and the transformation from "price formation market" to "market formation price" is realized.

Use cost index to guide project valuation and project audit

At present, the construction cost management agency to prepare the project cost index is basically a "typical engineering method". This method of index processing and calculation itself has randomness of sample data selection, and requires the cost data of this project to be comprehensive. In fact, many construction project cost data is incomplete, which leads to a large number of project cost data can not be used.

The use of computer technology, you can first aggregate the fine particle data, and then summarize the cost index of the whole project, which is an algorithm problem in computer technology, and the computer can draw the normal distribution curve of the data, find the representative project cost data, and calculate the construction project cost index that can truly represent this kind of project.

The determination of the benchmark rate of return of the high frequency test point of engineering economy for the first grade construction engineer

I. Concept:

A minimum standard level of return for an acceptable technical solution, as determined by a dynamic view of an enterprise or industry investor.

It reflects the judgment of investment decision makers on the time value of the technical program capital and the estimation of the risk degree of the technical program. It is the lowest profit rate level that investment funds should obtain, and it is the main basis for evaluating and judging the financial feasibility of the technical program and the comparison of the technical program.

2. Determination of benchmark rate of return:

1. Government investment projects shall be determined according to the policy orientation of the government;

2. Industry financial benchmark rate of return;

(3) For overseas investment in technology, national risk factors should be considered first;

4. Determine yourself.

Consideration: development strategy and business strategy, technical program characteristics and risk, capital cost, opportunity cost and other factors comprehensive determination.

① Cost of capital. The fees paid for obtaining the right to use the funds mainly include the financing fee and the use fee of the funds. The benchmark yield should at least be no less than the cost of capital.

② Opportunity cost. The maximum return that can be obtained from the use of limited funds for other investment opportunities that are forgone while the technical solution is to be implemented. It is formed outside the technical solution and cannot be reflected in the finance of the technical solution. The form of expression is sales revenue, profit rate and so on.

The benchmark rate of return should be no less than the unit cost of capital and the opportunity cost of the unit investment.
