Total floor area1,800 tsubo (fixed)In this article, we will provide a detailed comparison and explanation of ``2-story and 3-story buildings'' that can minimize the total investment including land cost, and ``4-story and 5-story buildings'' that can minimize the site area.
Specific to high floors (4th and 5th floors) where the floor space per floor is small.“Structural cost jump”and“Operation notes”becomes clear.
*Total floor area1,800 tsubo (fixed), the construction price per tsubo reflects the recent rise in material and labor costs (S-construction, system construction/standard specifications), and the land cost is based on standard industrial areas such as Sagamihara City (Tsubo 500,000 yenThe calculation is based on the assumption that the building coverage ratio is 60% and a truck berth is secured.

If you look only at the construction cost, a one-story house is the cheapest, but when you look at the total investment amount of "land + building"A 2-3 story building has the lowest total cost (break-even point)This is the result.
Compared to a one-story or two-story building, the construction cost for a 4-story or 5-story building is lower.1.5 times to nearly 1.7 timesJump up.The main factors are as follows.
In order to support the load of 4 to 5 floors (floor load 1.5t/m2 or more) and the horizontal force during an earthquake,The amount of steel frames for columns and beams is increasing rapidly.I will.Also, it hits deep underground.Length and thickness of soil improvement pileswill increase, and the cost of foundation construction will skyrocket.
In order to avoid delays in transporting cargo to the upper floors, it is necessary to install 3 to 4 vertical conveyors (VIFs) (approximately 15 million to 20 million yen per unit).Additionally, based on the Building Standards Act, it is mandatory to install an emergency elevator (approximately 30 million yen or more).
If you choose a 4- or 5-story building with a total floor space of 1,800 tsubo (medium-sized logistics facility), there will be operational risks as well as costs.
per floor360 tsubo (5th floor) ~ 450 tsubo (4th floor)and becomes narrower.By arranging ``3 vertical transport machines'', ``elevator'', ``emergency stairs'', ``toilet/rest room'', and ``passage'' within this narrow floor,The "effective storage area" where you can actually place your luggage will be reduced by more than 20% per floor.。
During peak shipping times, cargo is moved up and down between the truck berth on the 1st floor and the 4th and 5th floors, making it more likely that cargo will be waiting in front of the transport machine (congestion).
It has the best balance between increasing construction costs and reducing land costs.The total investment amount (approximately 2.25 billion to 2.28 billion yen) can be kept to the lowest level.。
