• Approvals: Engineer's written approval is mandatory before implementing any variations to drawn details.
• Discrepancies: Notify the engineer immediately if discrepancies exist between drawn details and specifications.
• Safety: Comply with all local authorities and statutory bodies for construction and safety regulations (e.g., SANS 10400 M, S & T for balustrades).
• Materials: Follow manufacturer's specifications for components like epoxy painting, weather louvres, and ducting.
• Ducting: Includes insulated and double-skin ducting in various sizes (e.g., 400x400mm, 800x400mm, 890x500mm, 600x600mm, 400mmø).
• Equipment: Supply and install AHUs (e.g., 1302x3300x1630mm, 9.0kW), DX down-blow units (e.g., 1900x2200x800mm, 36.5kW), chilled water up-blowers (e.g., 17.5kW), extraction fans, and fire dampers with motorised actuators (230V, 7 VA/4.5W).
• Electrical: All components must meet specified electrical requirements (e.g., 400/3/50 V/phase/Hz).
• Infrastructure: Connect to existing infrastructure (e.g., chilled water supply/return, electrical isolators).
• Structural: Coordinate with structural engineer's design for suspended reinforced concrete walkways and other elements.
• Finishes: Apply epoxy painting for floors and other surfaces as specified.
• Sound Attenuation: Install sound attenuators (e.g., 45 dB rating, lengths 2000mm or 2400mm) as per schedule.
• Layout: Follow floor layouts for K1 level, including plant rooms, UPS rooms, and generator rooms.

No explicit compliance requirements stated. Standard South African tender requirements may apply, including CSD registration, tax clearance, B-BBEE certification, and CIDB grading. Verify with SABC procurement policies.

Evaluation uses a two-phase process. Phase 1: Mandatory documents (automatic disqualification if non-compliant). Phase 2: Technical evaluation (minimum threshold: 95/110 points). Criteria: Construction Methodology (20 max, safety=5, rubble removal=5, dust/noise management=5, decommissioning=5), Interfacing with existing services (15 max, risk assessment=5, communication plan=5, quality assurance=5), References/Portfolio (30 max, 2-3 projects=20, 4-5=25, 6+=30), Project Execution Plan (20 max, tasks=5, duration=5, milestones=5, responsibilities=5), Technical Capability (25 max, Team Leader=10, Refrigerant Artisan=10, Plumber=5). Price evaluation: 80/20 preference point system (80 points for price, 20 for B-BBEE specific goals). Adjudication: Highest total points wins. Ties resolved by drawing lots. Specific goals: EME/SME 51% Black-owned=10, 51% Black-owned=5, 51% Black women-owned=3, Black Youth=2. Non-compliance with specific goals scores zero but does not disqualify.

Scope: Supply, installation, and commissioning of HVAC system for dual UPS rooms (A and B), battery rooms (A and B), and associated plant at SABC Radio Park. Key deliverables: Direct expansion down-blow units (UPS room B already installed, UPS room A onsite), chilled water up-blow units, chilled water air handling units, chilled water piping/reticulation, ventilation fans, duct system (with dampers/attenuators), full BMS control system (Johnson Controls integration), sprinkler system blocking in UPS/battery rooms, fire hose reels/signage/reticulation, decommissioning of existing UPS/battery rooms/HVAC, commissioning of new system. Design conditions: Johannesburg climate (summer dry-bulb 28.9°C, winter dry-bulb 1.1°C). UPS rooms: Temperature 15-25°C (setpoint 20°C), humidity 20-60% RH, filtration MERV 11 (min. MERV 8), positive pressure. Battery rooms: Negative pressure, dedicated chilled water units, duty/standby ventilation fans (2 per room), emergency activation switch. BMS: Bacnet TCP/IP, monitoring for temperature/humidity, fan VSDs, damper actuators, alarms, remote monitoring during commissioning. Fail-safe mechanisms required for all systems.
