A client is planning a slab extension on his existing building, as highlighted in the plan below. Theoptions are limited to one-way or two-ways slab models only and the slab would sit on simplesupports. Put yourself as a construction expert to advise the client on the following to design themodel.

1. Whether the floorisone-wayortwo-way?
2. In which directionwouldtheloadbedistributed
3. How many supportswouldberequiredfortheslabsystem?
4. Types of reinforcementandtheirorientation/direction.
5. What reasonable modificationontheslab'sdimensionswouldyousuggestswitchingtotheother model? The Clint would not be happy to go very far from the initial dimension ( thetolerancecouldbebetween150mm and -200mmonly)

8. For this project in-situ concrete is needed. Imagine that you as the technician have orderedsome materials including aggregates for a project you are involved in. What would be yourconcernwhenyouseesomecrushedlimestonesintheaggregates?
9. It is the date of pouring the in-situ concrete for the construction of the slab. From a technicalperspective, how placing concrete should be allowed. What action/s is/are needed beforepouringconcrete?Why?

(Hint: The answer needs to include any actions that should be taken regarding concretequalitycontrol)
