Proper Acoustic Management a Must-Have Feature in Modern Construction

Acoustic management is something very few people aware of. The properties of sound differ substantially depending on the frequency range. Sound can be divided into infrasound, audible sound and ultrasound. The science of acoustic management begins with reverberation times, which are the parameters used to objectively describe the echoic quality of a room. Long reverberation times will cause sound waves to be prolonged and echoes are created.

The more reverberant a room, the more people will raise their voices to compensate for the increased noise level to make themselves heard over the background noise. This only compounds the problem and makes for a very unpleasant environment.

Most people accept noise as normal without being aware there are reasonable acoustic solutions and sound control strategies to manage the problem. To correct these problems consideration needs to be given to the shape, size and volume of the area, the surfaces finishes, the type of activities, the sound system and the budget. Acoustic materials are used for reducing the noise. Let’s take a look at them-

• Diffusors

Diffusors are used in areas with flat ceilings or parallel walls to stop or reduce sound echoes that can occur.

• Absorbers

Midrange and high frequency absorbers are acoustic materials that absorb any frequency above 500 hertz. Absorbers, like diffusers, reduce ringing and echoing but they also reduce the reverberation time of a room.

• Bass Traps

These acoustic materials reduce the reverb time in larger spaces like churches, auditoriums and large recording studios.

Property developers are now getting requests from their clients for the properties with proper acoustic management. Property acoustic systems are readily available which can be incorporated as wall or ceiling linings into any project design. Used correctly, these will assist in bringing down reverberation times to the recommended levels for a range of project types. Proper sound control acoustics need to be introduced to reduce the noise level.

How Audits & Compliance Strengthen a Construction Project

Do you ever get overwhelmed by the number of regulations and the frequent changes in the Australian construction industry? Getting it right matters. The construction project audits and compliance companies provide the regulatory and compliance information you need, when during a project. Whether you are pending public or private funds, construction project are highly complicated undertaking requiring significant financial commitments.

Construction project audits program consists of:

• Subcontract analysis
• Quality assurance and quality control
• Labor burden analysis
• Reconcile project expenditures
• Change order analysis and pricing analysis
• Equipment rental analysis
• Preparation of control schedules
• Material purchases
• Direct labor analysis
• Bonds and insurance analysis
• Verification of contracted scope

A construction audit should also ensure that hazardous substances on the construction site are handled and stored properly. The auditor will closely monitor the company’s procedures for safe disposal of waste items and containing accidental spills to prevent injury to employees or the general public. If an untoward incident has taken place on the construction site, the auditor will review the company’s documentation and the treatment of any employees who were exposed to harmful substances.

Having the right controls in place is key to reducing risk and cost in a construction project. The companies of construction project audits and compliance regularly consult with clients to help them implement overall-

• Project control structure
• Change order management
• Financial budgetary management
• Reporting
• Safety and insurance

They offer superior control of the entire project and place you in a position where you can be 100% sure of your success. Audit costs pre-emptively to verify compliance of contractor charges. Enhance schedule, quality, and cost management control processes, policies, and procedures. Construction project audits and compliance allow an owner to evaluate a prospective contractor’s proposed rates and related internal cost structure before actually agreeing to same in a contract. In addition to the significant financial benefits of a construction contract audit, our independent reviews strengthen relationships among contractors and suppliers.
