**3. Architects and architecture**

#### **3.1 The architect**

The architect is well trained to design buildings and processes of achieving them (see engineer's view of the architect in [32]). Architecture ranks among topmost toughest courses in the world with students averaging 22.2 hours of study time weekly; 5.28 hours sleep per night compared to seven hours expert recommended [33]. Often called "master builder," a phrase traced to the original meaning of the word in Greek and Roman renditions. In "English speaking world" it was traced to 1563 and in 1898 (see [34]) A significant product of the architect is architecture, including landscaping which seen in [35] to include building transformed into a living art and expression; not a style. Architecture defines the limit of the city while in [36] "urban planners influence the entire communities with decisions about how areas are developed and even where building can be placed."

Additionally, leadership in of the building and construction industry may have been ascribed to the architect, but with new solutions from digital construction, computing and simulation, it is being challenged. Indeed, entry of more players from non-traditional construction cores, is therefore challenging the architect's leadership. Greater burden is on the architect and related institutions if the cap must fit. New thoughts in [37] are demanding a sectional leadership such as architecture management, construction management, engineering management. Also, with concept like integrated project Development (IPD) and "profit distribution of IPD" based on "degree of participation." Axiomatic to state, "a finished building represents the abilities of more than one individual" [37].

In another study, evidence supports a significant level of ignorance and indifference in the construction industry (see Appendix 1) [9]. All the same, the study demonstrated architect's leadership among peers in the construction industry with a significant lead of 80 percent in participation. This is despite the equal treatment across selected clusters- architecture, engineering, management, and others [9]. Additionally, the National Building Code of Nigeria, Neufert Architects' Data and 3D [38], ArchiCAD, AutoCAD. Apple Pencil(with iPad Pro) recently ranked among world-top 25 inventions [39], and in [40] Germany's most beautiful hydroelectric plant, all have significant big data input of the architects. All these point to the intersection of architecture and data science. Progressing, the chapter will develop and cover the implications of poor data for cities and city users after critical reviews of over fifty purposed sampled scholarly and appropriate articles. Personal experiences and opinions of industry leaders shall be helpful.

#### **3.2 Ignorance and dismissive attitude**

The figures below show the survey carried out in 2021 that gave graphic portraits of both ignorance and dismissive attitude of the architect as a professional creating data and significantly with data sciences skills [9]. See appendix 1.
