CONSTRUCTION PHASE IMPACTS. The Applicant anticipates that private sector investment in the construction of the Project would cost $70.2
CONSTRUCTION PHASE IMPACTS. 2.2.1 Noise No construction activity is currently scheduled outside 7am – 7pm. Whenever construction work is to be carried out from 7pm to 7am, the Contractor must apply for a Construction Noise Permit (CNP) and ensure full compliance with the Noise Control Ordinance requirements. All construction works should be prohibited during 11pm to 7am unless the Engineer’s Representative considers that it is unavoidable and necessary. The construction works will involve temporary protection and/or diversion of utilities, demolition of existing entrances, construction of Excavation and Lateral Support (ELS) cofferdam, excavation to formation level, tunnelling, construction of the Subway and the underground ancillary structures, and re-construction of the above ground entrances. The Subway will be constructed in two sections simultaneously, with cut and cover excavation adopted in Section 1 and mined tunnelling construction adopted in Section 2, as shown in Figure 2.1. Each section will have one set of Powered Mechanical Equipment (PME) for the work activities. Potential impacts on Noise Sensitive Receivers (NSRs) during the construction stage will arise mainly from PME. The PMEs to be employed in this Project include generators, air compressors, excavators, lorries, mobile cranes, concrete pump trucks, concrete lorry mixers, vibrating hammers, drill rigs, poker, ventilation fans, circular saws, etc. The plant inventories for each construction activity are presented in Appendix II, together with the Sound Power Levels (SWLs) for each PME without mitigation measures. Accordingly, the maximum SWLs for each construction activity are calculated and are tabulated in Table 2.1 below. Table 2.1: Maximum SWLs for each Construction Activity (Unmitigated Scenario) Construction Activities Maximum SWL, dB(A) Section 1 Utilities Diversion along Xxxxxx Road 110 Utilities Diversion and Demolition of Entrances 111 Installation of Pipepile and Sheet Pile 110 Surface Excavation 109 Construction of Temporary Staircase 108 Further Excavation (Works under Road Decking) 108 Construction of Subway (Works under Road Decking) 107 Construction of Above Ground Entrance 111 Backfill 109 Reinstatement 110
CONSTRUCTION PHASE IMPACTS. The Applicant anticipates that private sector investment in the construction of the Project (excluding land acquisition) would cost approximately $6.57 million. If we assume that 50%2 of the construction spending would be sourced from within the county, we can project that there will be nearly $3.3 million in net new spending in the county associated with the construction phase. Table 2 Based on $3.3 million worth of net new direct spending associated with the construction phase of the Project, Camoin 310 determined that there would be over $4.8 million in total one-time construction related spending supporting 24 jobs, and nearly $1.9 million in earnings throughout the county over the 18-month construction period. Table 3 Based solely on information in the application, the project timeline of 18 months should allow the Agency to reach the conclusion that there is a likelihood of accomplishing the Project in a timely manner. Although we are not construction experts, nothing has come to our attention that would cause us to reach a contrary conclusion.
