E responses from 20 out of your 34 respondents. The outcomes confirmed (see Table five) that there was larger quantity of projects carried out (imply = 10.35, SD = 21.98) than for utility damage reported (imply = two.1, SD = 3.05). Comparing the two, the ttest located that this difference will not be substantial, t(19) = 1.81, p 0.05. This suggests that because the number of projects increases, so does the number of reported damages, supporting the hypothesis that the total number of projects is usually a predictor of utility damages reported.Buildings 2021, 11,10 ofTable 5.

Table 6 presents the model summary to ascertain the correlation coefficient (R) and coefficient of determination (R2 ). The results show a value of 0.579 for (R) and 0.335 for (R2 ), that are close to 1.0, which means the dependent and independent sample variances look to be dependable and fit a regression line. Table 7 shows the result of ANOVA analyses. The results indicate a low value of (pvalue) because the two compared groups are significantly diverse (Sig. is less than 0.05). Having said that, the ANOVA regression test shows one of the pvalues as much more than 0.05, whilst the other value shows much less than 0.05, as seen in Table eight. The parameters of possibly liner relation are calculated as 0.73 and 0.077 for an initial relation among the number of conducted jobs as well as the number of expected utility damages, asBuildings 2021, 11,11 ofseen in Equation (1) beneath. In addition, (Figure 3) shows a greatest fit line for the probable liner relation of trending scatter points: Y = 0.73 0.077X (1)where: X could be the number of jobs carried out, and Y will be the quantity of utility damages that can be projected to happen under present operating circumstances.Figure 3.

Discussion This study sought to establish the factors for utility damages and strikes through construction activities in New Zealand. It verified the linkages involving the frequency of strikes plus the high-quality of asbuilt records held by utility owners so that the significance of asbuilt drawings could be produced extra apparent. The findings offered.
