Is your parking space expensive? Revealing the Five Major Components of Parking Space Prices
Have you ever had an experience where you finally managed to gather enough down payment to buy a house, only to be stunned by the parking price and say, “It’s just four lines and one frame.
Why is it even more expensive than my car.
Turning construction waste into treasure, Europe introduces new regulations for recycled concrete precast components
Against the backdrop of the global construction industry accelerating towards low-carbon transformation, how to properly handle and utilize massive amounts of construction waste has become a core issue in the engineering industry.
This week, the authoritative institution in the field of precast components in Europe officially released the “2026 Application Guidelines for Recycled Concrete Components”, while also warming up the upcoming BIBM 2026 conference in Rome.
This marks a new stage of standardization and scale in the application of “recycled concrete” in structural precast components.

Hangzhou Metro Line 15, Section 4, Gold to Construction, Double Line Connection
Recently, as the cutterhead of the No.
625 shield machine of China Railway Equipment slowly broke through the wall, the left line of the section from Jinjilu Station to Jianshe Yilu West Station of Hangzhou Metro Line 15, which was constructed by China Railway First Bureau, was accurately connected, and thus the double track tunnel of this section was successfully connected.

When do concrete pavement joints need to be cut?
Due to its low tensile strength, concrete floors can be cracked by the tensile stress generated during thermal expansion and contraction.
And seam cutting is the use of manual intervention to cut horizontal and vertical seams to guide and control the location and direction of concrete cracking.

Dry goods | Comprehensive analysis of crack resistance of large volume concrete: from mechanism to control, a set of solutions to solve it
In construction engineering, the crack resistance of large volume concrete has always been a pain point in the industry – once cracks appear, they not only affect the aesthetic appearance of the structure, but may also weaken the bearing capacity, reduce durability, and even cause safety hazards.

How to control the quality of each stage of concrete construction? These are the methods!
13 sets of typical cases of special construction plans for hazardous projects (3D color images), including Bailey beam high formwork, steel structure, large-span high suspended structure formwork platform, aluminum alloy formwork support, cast-in-place box girder, tower crane installation and removal, corridor suspended ceiling curtain wall hoisting, hydraulic climbing formwork, steel mesh frame, bridge jacking, foundation pit support, earthwork excavation, cantilever scaffolding, cable tower and other special constructions.
They play a key role in eliminating major accident hazards in construction and preventing major safety risks in engineering construction, and are provided for learning and reference.

Concrete Engineering (Phase I)
Concrete used for hydraulic structures such as dams, water gates, pump stations, embankments, bridges, culverts, etc.
is called hydraulic concrete.
The reasonable design of hydraulic concrete and strict control of its construction quality are important guarantees for the engineering quality of hydraulic structures, which are related to the safe operation of the entire hydraulic structure.
Therefore, during the entire process of constructing hydraulic structures, the quality of concrete should be tracked and tested from beginning to end to ensure that the quality of concrete used for hydraulic construction meets design requirements, is stable, and has minimal fluctuations.
