Introduction
The design aspect of any engineering structure is dependent on the requirements of safety as well
as measures that satisfy its functionality (Al-Chaar et al. 2016). It is important to note that
aesthetic value is just but the quality improvement mechanism that should only be considered
last in the requirement list of the design. This particular paper highlights the design requirements
for the Typical on-shore pre-cast yard(Coombes 2013).
Requirements and considerations for the design
Structural design approach
The structure of precast behavior hinges on the behavior of the connection and should offer;
- Considerations of feasible productions
- Resistivity to the forces of the design
- Resistivity to the changes in volumes and other forces related to the structure
- Sufficient durability
- Considerations of feasible construction
- Resistivity to fire
- The ductile property when deformation is in excess.
Floor panels
Concrete of grade M 30 and above is required for the concrete reinforced floors. The desired
strength of the floor is obtained by the units of pre-stressed concrete floors in the design. The
floor panel should be constructed in a way that the thickness should take into account the service
activities. The recommended thickness of the concrete slab should not be less than 50 mm.

Designing the panels should be as per the document endorsements for reinforcement and
retailing management.
Walls
Designing of the walls (structural load bearing) should be done as recommended by the
documentation in the relevant materials(Allen 2016). Designing of internal nonload bearing
walls should in the form of plain concrete walls reinforced nominally purposely for stress
similarity and control. Different partitions of the wall system can also be applied in the design of
such walls. The grade for the concrete walls should be M 10 and above.
Connections
The idea of emulative detailing is used in designing a system of PLCP to ensure the same
ductility and strength of the structure on completion. The emulative behavior is usually attained
by wet connections in the system of PLCP.
Structural system
A superstructure is compost of columns, beams, slabs and precast construction of RCC wall as
its structural system. Floor-slab represents the stiff diaphragm that transmits longitudinal forces
to the walls. Cast-in-situ which is a conventional method of construction is applied for the
ground floors. Precast technology including a system of solid floor slab and the precast wall is
applied for the construction of the town and higher floors.
Wind loads
Calculations of the pressure of wind should be done as per the document recommendations.
Design Philosophy

The joints of the precast structure which is considered massive should be designed in a manner
that caters for the forces of the corresponding discrete. Moment and shear resisting joints should
be properly allocated to provide resistance to the vertical loading. Designing of individual
components at different construction stages should ensure suitable end conditions as well as
loads.
Design Loads
Dead loads – this consists of the total self-weight of the frames, self-weight of the slabs and total
self-weight of shell element modeling of the structure (Harris 2013).
Imposed loads – these are loads predicted to act for the rest of the periods and include:
- Waterproofing: determines the properties of waterproofing materials such as material
type, slope, and thickness.
- Internal partitions: calculations of false ceiling or internal partitions are done from the
unit weights extracted from relevant materials on the basis of thickness and material type.
The installation
Coordination of the pump operation to realize output of 400m3 per hour
The structure of the intake of the water should be approximately 50m wide and be temporarily
have length of 85metres of concrete. In order to realize output of 400m3 per hour, the depth will
be about 15.5 meters with respect to the level of the ground. The total intake of the water
channels which are located after baffle walls. Considering that this particular structure of the
intake is constructed as deep foundation on the line of the shore, the system of shoring is
