Mobile apps increase productivity on construction sites, which is essential in the modern construction industry for its fundamental success. Mobile app technology allows engineers and contractors to instantly edit the design in AR (augmented reality) or a plan on their tablet – this is how the industry is rapidly changing with the help of innovation and technology. Engineers, foremen, and architects can also draw, make changes, list details, provide comments, make suggestions, make cost estimates, and propose improvements that can be shared with anyone in the office or with a client. Construction mobile apps allow contractors and engineers to record and view ongoing activities on a construction site, get weather forecasts, and calculate labor productivity. Project managers have access to project directories and can attach any changes they make to drawings and list items to other colleagues in the office. Say no to plagiarism.

Mobile construction devices have transformed from surveying to on-site inspection, which has become a productive tool in the construction industry. These construction mobile apps have helped many construction sectors save money and have helped effective collaboration between clients and suppliers, construction site workers and customers work more productively and effectively. Engineers or architects can upload or download plans digitally as they work or email them to other colleagues or project managers. The work routine can be planned using the construction mobile app, in that case the construction site manager can easily know how many workers are on site or who is absent, this helps companies save money and labor costs. Mobile apps are also the best solution for keeping track of working hours and equipment in the field. In addition to having all these advantages, it can also be integrated with other platforms whose documents can be shared via SharePoint, Drop Box and Google Drive. It is a great tool that can help reduce inefficiencies in project delivery. According to Sage Software, the majority of construction mobile apps are used to access customer and job information (48%), followed by drawings, schedules, photos and documents (47%), daily field reports are approximately (38%), labor costs and project reports (36%), time acquisition and approval (30%). Documentation and measurement play an important role in the construction industry, it helps streamline processes and update vital information on the construction site. Architects and engineers document information in real time without hassle or leaving the jobsite, plus the foreman or project manager can review, make changes and ensure all necessary information and updates are changed before workers leave the jobsite. This helps eliminate any obstructing hazards on the job site and improve information sharing, which significantly increases productivity and efficiency. In the construction industry measured drawings are crucial, it is the formalized product of documentation, which helps the architect and engineers to have a clear blue print vision and information they can work with. These documented drawings help the engineer or architect to.
