Project Planning of Building Acoustics

ACAD has a well-developed structure for the project planning of building acoustics. Protection against noise disturbance is adapted to the project and reported in an acoustical programme. In the acoustical programme, acoustical requirements are normally established. Proposals in principal for measures for framework, façades, floors, stairs, doors, entrances, false ceilings, machine setups, heating, water and sanitation installations and lifts etcetera are provided.

In preparation for each assignment, a preliminary study is conducted resulting in a written assignment analysis. This analysis is submitted to the customer and is to be approved by him.
Functional testing, measurements and inspections are always conducted in accordance with current standards and guidelines. Results from testing, measurements and inspections are documented in reports with pronouncements.

After final delivery, a meeting is held with the customer where the written assignment description is reviewed in order to check that intentions have been fulfilled and that the delivery can be approved.

The Project Planning Procedure

Work with acoustic project planning is divided into phases that follow a normal project planning procedure. It is often important that acoustic characteristics enter into the early planning stage of the project.

Programme Requirements

Appurtenant requirements of authorities and the orderer are reported and interpreted in principles for action and functions. In this early stage, we can contribute with the planning of how to build so that traffic and other noise cause as little disturbance as possible.

Inventory

Existing buildings are inventoried and measured to discover pre-conditions for measures. With sound measurements, you can verify at an early stage whether there are any walls, joists or installations that need to be addressed or if the construction meets modern requirements. There lies an economic benefit in an early acoustic inventory!

The Idea Stage/Sketch Stage

Here, the fundamental conditions are formulated together with architects and other specialists. With our views on acoustics in different environments, we can help to formulate a quieter, more efficient project.

Main Document

The constructive principles are clarified, coordinated and presented.

Construction Document

The details of the constructions are specified. The presentation of the acoustic measures is normally worked into the documents of the main specialties. Each specialist consultant receives his instructions for a coordinated acoustic solution. Special acoustic documents may be required in certain projects presenting requirements on walls and joists for sound-proofing and step sounds. A document is often required that shows how the repair and sealing of lead-throughs are to be carried out to meet sound and fire requirements.

Acoustic Quality Assurance

When the building phase has begun, tests should be conducted of type solutions for walls, joists and doors as soon as possible. The earlier any faults are discovered, the less costly remedies will be.

Before the project is finished, ACAD performs a precise measurement of sound-proofing and sound levels from installations and traffic. The measurements are presented in a report that confirms that the building meets the requirements of authorities and the orderer.
