- Statement of Work PROVIDE A WRITTEN ACOUSTICAL & MECHANICAL STUDY FOR A LARGE CONFERENCE ROOM Location: Columbia Center Building 701 5 th Avenue, Suite 2900 Seattle, WA 98104 1.0 GENERAL. •1.1.1 The purpose of this project is to provide acoustical and mechanical requirements of a large conference room that will be modified for table and chair layout. The large conference room will be used for audio and visual recording, as well as broadcast to other SSA locations. •1.1.2 The sound levels of the existing conference room and the sound of the noise generated by the mechanical equipment that is installed above the ceiling tiles will require measurement. •1.1.3 The mechanical equipment installed above the ceiling tiles consist of four (4) water-source heat pumps that are used for space heating, cooling, and ventilation. In addition, a ventilation fan has been identified that is used for the floor ventilation and serves to pressurize the space in case of a fire/smoke event. This ventilation fan cannot be moved or modified from its present location. However, the water source heat pumps can be relocated to the adjacent hallways to reduce the mechanical noise. The new ductwork, supply and return grills will be modified to reduce the mechanical noise impact of this space. The proposed new location of the mechanical system will be in the adjacent hallway, where the mechanical noise will not affect the new large conference room. •1.1.4 The acoustical Study will drive the mechanical part of the work to mitigate noise which will need to be defined, designed and constructed; and provide ways to verify completion after construction. •1.1.5 Code Compliance, Room Capacities, and ADA will need to be addressed to ensure compliance. •1.1.6 The acceptable noise levels for a typical large conference room shall be between 25 and 35 decibels (db). The existing mechanical noise levels are excessive and were measured to be greater than 45 db. •1.1.7 Weekly conference calls to provide project status will be required and should not last more than one (1) hour. •1.1.8 The acoustical and mechanical requirement will be provided as a written Study that will be presented to a General Contractor for pricing and construction. Identification of specific building shell items will be part of the written Study. 2.0 SCOPE OF WORK. 2.1 The acoustical engineer contractor shall furnish a written Study that includes the technical data, technical drawings along with calculations sheets, audio, acoustical, mechanical needs of the large conference room, and final assessment of the work performed. 2.2 The Study shall be as follows: •· Provide baseline sound level readings at various locations of the conference room, and document the results. The measurements shall be taken at various octave band levels, and shall be taken over a period of time. •· Identify the source of the noise, and provide feasible and cost effective solutions to reduce the noise level readings to acceptable levels. •· Indicate how acoustical treatment i.e. ceiling & wall paneling including interior, audio visual system, noise & soundproofing, seating layout & line of sight and lighting are addressed. •· Provide proper sound continuation outside of the conference room. •· Provide a layout of the audio visual equipment for best-use for the conference room. •· Coordinate with the building engineering and operation and maintenance staff, through GSA Project Manager, to assure that the proposed solutions are acceptable to the building operation and maintenance team and will not impede maintenance of the mechanical system. •· Work with the mechanical design engineer to incorporate the proposed solutions in the mechanical design of the retrofitted system. •· Coordination with the construction team to make sure the installation of the proposed solutions will not negatively impact the installation of the new solutions. •· Communicate with the GSA Project Manager any potential issues that will affect the outcome of the retrofit project and may cause noise levels to be in excess of the desired levels. •· Work with the GSA Project Manager and Mechanical Engineer to resolve potential issues that may arise during construction. •· The acceptable noise levels for this type of occupancy shall be 25 to 35 db. •· Provide post retrofit sound level readings at the various location of the room, to verify that the noise level readings are within the prescribed levels. 3.0 WORK HOURS AND SITE ACCESS. 3.1 A total of three (3) meetings are intended for this PWS. The first meeting involves a site visit involving the customer, GSA Regional Experts and the Building's Mechanical Engineering team. This meeting is to clearly understand the intent use of the large conference room, issues with the current layout, audio load and layout and incorporation of acoustical needs for the conference room. The second meeting would involve additional clarifications and/or follow-up to the initial meeting. The third meeting would involve the presentation of the Acoustical Engineers findings and written draft Study that incorporates previous work that have been performed and discussed during the initial meetings. Coordination with the Building Engineer will be required to shut-off mechanical to hear sound. This meeting can be arranged during the second site visit. 3.1.1 The Project Manager for this project is Carol Hunt who can be contacted by telephone at (206) 220-4384. 4.0 SITE SECURITY REQUIREMENTS. 4.1 The Acoustical Contractor's access to the location will need to be pre-arranged in advance through the GSA or SSA. 5.0 COMPLETION. 5.1 The following timelines for the project has been indicated and must be met in order to meet completion: •· Initial Meeting - should take place within three (3) working days of award and will involve an on-site visit with the Project Manager, SSA Representative, Regional Experts and the Buildings Engineer to discuss scope of work and intended results •· Within five (5) working days from the initial meeting - provide a project update/status that will not exceed one (1) hour •· Second Meeting - Consist of an additional site-visit and/or consultant inquiry and will be scheduled within three (3) calendar days from the first project update/status meeting that occurred five (5) working days after the initial meeting •· Third Meeting - Present findings and delivery of scope of work within ten (10) calendar days after the Second Meeting •· Submit Final written Study within ten (10) calendar days of the Third Meeting. 5.1.2 Working days. Working days shall mean weekdays, excluding Saturdays and Sundays and Federal holidays. Calendar Days. Calendar days shall mean weekdays, including Saturday and Sunday and Federal holidays.
