What determines the cost of explosion resistant modular buildings?
1. The Blast Charge and Duration
Within a given site, the location of an explosion-proof structure might change many factors and affect the design, analysis and manufacturing as both the pressure and duration of the blast load can vary significantly. Therefore, special designs and analyzes are made according to the location of the building. Subsequently, cost calculations are made for explosion-proof modular structures, taking into account both the exposure duration and explosion pressure.
If the risk on-site is unclear, HARDSHIELD engineers can perform site risk analysis and estimate the blast design parameters for you.
2. Dimensions and Usage Type
One of the main factors determining the cost of explosion-proof modular structures is size. Design and production can be made in any desired size. In addition, thanks to the combination of modules with each other, very large explosion-proof structures can be created. For example, a large occupational area of 180 m2 can be created by combining 6 modules, one of which is covers 30 m2 (2.5 m * 12 m). In addition, the interior can be divided into partitioned areas according to the required usage.
3. Number of Explosion Proof Doors and Glass
Complementary products of explosion-proof modular structures are explosion-proof glass/window and explosion-proof doors designed and manufactured by HARDSHIELD. explosion-proof doors and windows can be added to structures in various sizes according to the customer's demand. The dimensions and quantities of doors and windows might affect the cost.
4. Desired Interior Features
According to the customer's demand, all explosion-proof modular structures can be modified according to the type of operations and usage it should serve. For example, dining hall, office, dormitory, watch box, control room, etc. Therefore, the interior feature and the desired material might affect the cost.
5. Requested Special Modifications (Fire resistance, gas tightness, bullet and rocket proof etc.)
In addition to explosion resistance, with some modifications, modular structures can be designed to resist fire, bullets and rockets. The standard explosion proof modular structures manufactured by HARDSHIELD are sufficiently fire resistant. However, resistance to special fire incidents demands additional design and materials. In addition, protection against gun or rocket launcher ammunition can be provided in explosion-proof structures that vary according to usage. In order to provide these features, some changes will be made in the design, analysis method and material and it will affect the unit cost.
