Technical Drawing Management and Public Infrastructure Coordination in Local Government Services

Abstract

This study evaluated the extent to which technical drawing management supported public infrastructure coordination in local government services, with particular attention to drawing control, records handling, information accessibility, communication, and synchronized project implementation. A cross-sectional explanatory survey design was employed among 30 selected employees of the Local Government Unit of Santiago City who were directly involved in engineering, infrastructure documentation, planning support, and related coordination functions. Data were gathered using a validated 40-item Technical Drawing Management and Public Infrastructure Coordination Scale and analyzed through means, standard deviations, Spearman’s rank-order correlation, and bootstrap linear regression with 5,000 resamples. Technical drawing management obtained an overall mean of 3.73, while public infrastructure coordination registered 3.70, indicating generally favorable practices. Drawing accuracy and standardization emerged as the strongest technical management dimension, whereas revision and version control recorded the lowest mean at 3.43. Work synchronization was the weakest coordination dimension at 3.41, particularly in sequencing interdependent activities and adjusting schedules following project changes. Technical drawing management was significantly associated with public infrastructure coordination (ρ = .664, p < .001) and significantly predicted coordination performance (β = .653), explaining 42.7% of its variance. The findings established that reliable technical drawing practices contributed substantially to coordinated infrastructure operations, although weaknesses in version control and work synchronization remained. Strengthening revision tracking, document circulation, technical information exchange, and schedule integration may improve continuity and coordination across local infrastructure services.
