CE 1.2 Project Background
CE 1.2.1 Characteristics of the project
The scope of the project was to design the multi-storey precast concrete form in detailed
manner through a team work and every individual was asked to contribute in the project. I had to
manage the floor spaces in manner to keep them flexible as much possible in manner to allow the
multiple occupancies to be incorporated within the developed project. We were restricted for the
permanent internal partitions within the two different office areas and thus, we had to develop
the design for the single row of the columns in the offices. I had to develop the design on which
the entire development of the project was to be developed and allow the other stakeholders and
human labour to contribute their effective role in the successful development of the project.
CE 1.2.2 Objectives developed for the project
I had to execute the project as a group and so we developed the following objectives for
the development of the successful design that can be utilized for the project:

 To analyse the fundamental requirements for designing the precast concrete
 To develop a sophisticated design for the delivery of the project
 To accomplish the entire project within the expected time
 To deliver the project within expected budget
 To identify the proper dimensions for the concrete skeletal structures
 Consider all the loads while designing the skeletal
 To successfully develop the design and construction of the precast concrete multi-
storey framed structure
CE 1.2.3 My area of work
To analyse the entire environment of the design being proposed for the development of
the building design considering the structural stability, architecture features, construction
programmes, and M & E and HVAC services. I had to develop the sophisticated model for the
structural components, showing floor spans, structural toppings, finishes, beam types and sizes,
column positions and wall positions. I had to develop the design considering the following
characteristic loads and materials:
Characteristic Loads (kN/m2)
 Services and Ceiling = 0.60
 Floors Superimposed (incl. demountable partitions) = 5.00
 Roof Superimposed = 0.75

 External glazing = 0.50
 Dead load (sheeting, purlins, truss, ceiling) = 1.20
 Wind pressure (incl. pressure coefficients) = 0.70 2
 External blockwork (incl. insulation) = 2.00
Materials (N/mm2)
 Reinforced beams, walls, cores, fck = 40
 Concrete Prestressed beams and slabs, fck = 60
 Insitu infill, fck = 30
 Steel Rebar, fyk = 500
 Self weight of reinforced concrete = 25 kN/m3
 Stability tie steel, fpu = 1750
 Dowels and bolts, fyb = 450
 Neoprene pad to double-tee slabs, fc = 10
 Plate, rolled section, solid sections, py = 275
 Cover to protected rebars and steel inserts = 25 mm
 Cover to all rebar and exposed steel sections = 40 mm
 Level ground. Top of foundation below ground
