• Replace exterior waterproofing and sealant joints - Include all exterior wall control and expansion joints.

• Provide new marquee sign. A new marquee sign will be required to be installed behind the building setback as required by current zoning regulations. The installation of the new marquee will require some tree mitigation to allow adequate viewing access to the new marquee.

• Provide new way-finding site signage. Design team shall coordinate with school staff to provide proper way-finding site signage.

• Replace exterior waterproofing/sealant joints. Existing sealants & waterproofing is required to properly seal the building envelope.

• Existing fire alarm system shall be protected during any portion of renovation that produces excessive dust.

• The new fire alarm system will be tested and commissioned prior to removing any existing fire alarm system.

• New electrical circuits needed for new fire alarm will share existing fire alarm circuits such that new circuits are not required, and the old system will be removed after the new system is fully functional. This will result in a larger load per existing fire alarm power supply circuit for only a brief period.

• A BDA System is required by code. Only the Dallas Fire Department can advise Dallas ISD if it is not required. Contractor shall contact fire department for investigation.

• A performance specification for the installation of a BDA system will be included and the contractor will exercise the scope with a 3rd party specialty engineer registered to design, specify, and install such a system as part of the Fire alarm replacement.

• Lighting controls will be upgraded to match Dallas ISD TDG's. New control devices consisting of relay panels capable of meeting the criteria for time-of-day control devices will be integrated into existing exterior lighting circuits.

• Where new circuits are required for new HVAC mini-split systems in MDF/IDF rooms, new circuits, conduit, disconnection devices and connections will be made from readily available space in existing distribution equipment.

• Where existing HVAC systems are replaced with new, existing circuits will be reused where they meet or exceed the energy requirements of the new equipment.

• In cases where new HVAC equipment requires more than existing circuits are capable of providing, all existing circuitry to each affected HVAC unit will be demolished and replaced with new. New over current protection will be provided from available spaces in the same panel, or from other panels with spare

capacity capable of meeting the energy demand for the new equipment.
