Unipolar scales ask respondents to score the existence (or absence) of a certain quality or feature, such as usefulness or satisfaction. A five-point scale is commonly used for this.
Linear scale questions allow users to respond to a statement or inquiry with a number response. You may compute the score by assigning standard points or weights to each response. (Scorecery - How to Assign Points for Linear Scale Question?, n.d.).
In this question five important factors were listed, and the participants were asked to rate each factor from 1 extremely effective to 5 not at all effective. Each factor will be discussed below.
4.4.2.1.Cooperation between suppliers and contractors:
Cooperation between suppliers for the 3D concrete printing industry and contractors is an active and main factor for every growth and development of this industry in the future and this cooperation occurs when there is a unified pattern that all those responsible for this type of industries can emulate.

means that this point should be taken under consideration, and should be studied in order to develop the 3-D printing concrete technology.
4.4.2.2.Develop academic and scientific research such as codes to be followed:
As it is known that the development of each industry depends on the scientific aspect, and the development of the practical aspect is very necessary, especially in the construction industry, so 3D concrete printing must be fortified and supported with research and scientific studies in order to spread its use and at the same time facilitate its use.

The above table and chart show that, 19 of the response select extremely effective, 7 of them select very effective, 4 only goes with somewhat effective, and no one choose not so effective or not at all effective. This means that this factor is an essential factor, and real measures must be taken for it to develop this technology.
4.4.2.3.Follow a strategy to develop Skilled employment for Operation:
There is no doubt that any industry in the world needs professional craftsmen and workers in it, as is the case in 3D concrete printing. This technology needs very skilled workers, although most of the work is done by the machine, but there are basic touches that the professional worker must put in order to help the computer and machine to produce a perfect final model.

From the table and chart above its clear that, 11 response choose extremely effective, 9 of them select very effective, 8 response goes with somewhat effective, and 2 select not so effective, finally zero select not at all effective. This means that the development of this technology is linked to the development of manpower and the treatment of shortages and weaknesses in this field.
4.4.2.4.Leadership commitment:
In all cases, wise leadership is always the basis for the development of any business, and in the case of 3D concrete printing, the leadership and its support are a major incentive for development in this field, especially since the technology is new and needs to be adopted.
For example, the Emirate of Dubai adopted this technology and developed more than one scientific research and learned about projects that were completed, and all this is due to the wise leadership.

Leadership commitment.
From the information above, 10 of the response select extremely effective, 8 of them select very effective, again 8 choose somewhat effective, 4 choose not so effective, finally no one selects not at all effective. This means that there is a supportive part and a large part also neutral to this idea, but from my point of view that the leadership has an influence in one way or another in the development of any modern science or technology by setting a clear plan and following it.
4.4.2.5.Increase the number of suppliers:
As with the previous questions, the participants differed between supporters and opponents of this factor. But in fact, the presence of many suppliers in the country is an important point to allow the contractor to choose the appropriate supplier. This also contributes to reducing prices from suppliers. This factor must also be taken under consideration.

The final point results approve that, 8 response select not so effective, 7 of the response goes with very effective, 6 choose extremely effective, again 6 select somewhat effective, finally only three select not at all effective. A large part of the participants believe that this factor is not necessary to this extent, and if the number of suppliers is few, it does not significantly affect the development of this technology.
