Construction Techniques:
There are a variety of equipment types that can be utilized to fill JOESCO bastion units. Like: wheeled and tracked excavators filled with either standard buckets or clam-shell grabs;Tipper truck/dump trucks fitted with lorry loader grab attachments;Concrete skips lifted by cranes, and skid steer loaders. The simplest and easiest to use is a front end-loading shovel. Particularly when the structure is below 3.5 meters(11’)high.Front end loading shovel size should be selected to match the size of bastion cell being filled. The front bucket of a backhoe loader is suitable for all cells up to QS1 in size.

Many factors will effect the time and numbers of operatives that it takes to construct any given structure, but the more common ones are: Availability of resources and manpower;Haul distance from stockpile for the fill material
.Accessibility and ground conditions;Type of JOESCO bastion unit being used;Experience of the operatives with the system and the structure being built

The key to working out the quantity of manpower required:Ascertain time available for the construction;Calculate the construction time with 4 men and loading equipment.This is your basic construction figure, if you cannot achieve completion within the given time frame then an increase in manpower and equipment is required.

For basic linear construction of 2 JOESCO bastion QS1 unit of 10.6m length, 10 cells, allow 20 minutes using one loading shovel and 4 men. This includes unpacking from a pallet, bouncing the cells out and filling. This is as good a figure as any to use as a guide figure for basic JOESCO concertainer construction.

Maintenance and Repair:
There are two methods of repair which can be found in the HESCO construction guide for Engineers. An additional method would be when a cell is not badly damaged but simply requires some reinforcement. A new cell or unit can simply be placed against the damaged area and securely attached.
