Evaluation of Construction Site Noise to Allow the Optimisation of Construction Processes and Construction Machinery Selection

Abstract

During the pre-construction phase of an investment project, a construction plan is usually prepared by the building contractor. It contains financial plans, schedules, technical regulations with working procedures and proposals for the deployment of construction machinery and work teams. These items are then optimised in order to save money, shorten construction time and increase the quality of the final work while ensuring environmental and safety standards are maintained at the site. The ecological aspects of building work include compliance with the hygiene limits for building site noise, which is caused in particular by the simultaneous operation of machines. In the Czech Republic, limit values are set by Government Regulation 272/2011 Coll., as amended, on the protection of health against the adverse effects of noise and vibrations. The evaluation of construction site noise is not usually performed by contractors themselves and noise is usually measured only at the construction site, where work is limited or additional measures are taken in the case of values that exceed the stipulated limits. As the values in the construction plan should be as close as possible to reality during the implementation of the plan, it would seem appropriate to include such noise assessments within it. The purpose of this paper is to present an example of such an evaluation from the formal and material standpoint. The assessment has been conducted in the form of a specific noise study, expanded by a commentary on the treatment of the hypotheses. It shows how to obtain input data for evaluation, divide sub-calculations and use the supporting SW of the Hluk plus product for the purposes of construction information modelling, as well as how to correctly set noise sources and the positions of measured points for evaluation by the model within this programme. Subsequently, options for the evaluation of appropriate measures are listed, including their inclusion in reassessments.

Multi-Criteria Optimization of Mechanized Earth Processes and Its Impact on Economic and Environmental Sustainability

“…The outputs of this paper are a supporting process for 5D BIM (construction budget) and 6D BIM (construction technology and quality). The results of the work presented in this paper have a direct impact on economic [7] and environmental sustainability [8][9][10], which can be achieved in the phase of construction preparation. As part of this research work, another plan is to design suitable software to increase these effects.…”

Generation and Characteristics of Construction Noise in Rail Transit Engineering Enclosure Structures

“…The investigated construction stages were typically concentrated on earthworks [19], main structure construction, or the operational phases of subways [3]. Furthermore, existing studies on the identification of noise sources primarily focused on common construction machinery, such as excavators, pile drivers, and cutting machines [20]. There are two significant differences between the noise issues in enclosure construction and other projects.…”

A mechanically adjustable acoustic metamaterial for low- frequency sound absorption with load-bearing and fire resistance

“…The noise absorption metamaterials can achieve wideband and low frequency noise absorption through parametric design. However, for variable noise, such as construction noise [24,25] and aviation noise [26][27][28], the building noise may come from different noise sources at different time periods, and the aircraft shows different noise spectrum during takeoff and landing. For this case, the broadband noise control may not solve the problem of random noise with discrete peak spectrum, and it will also lead to redundancy in the spatial size of the broadband sound absorption material composed of multiple units.…”
