The tender requires the design and construction of temporary tower crane bases for the Tzaneen Dam wall upgrades.

Key design specifications:

• Two tower cranes: CTT 181 and CTT 202.
• Each base comprises a 5.5m x 5.5m reinforced concrete foundation anchored into in-situ rock using rock anchors.
• A 3.5m x 3.5m reinforced concrete plinth supports four 1m x 1m reinforced concrete columns (height 8m, spaced 1.9m center to center).
• Columns are braced at 2.5m intervals using 305 x 165 x 54 steel I-beam sections.
• Combined length of bases: 12m; final top elevation: 692.00m.

Design criteria:

• Loading: Detailed crane load tables provided for in-service and out-of-service conditions with various wind speeds.

Safety considerations:

• Design emphasizes safety, efficiency, and adherence to project criteria.
• Global stability factors of safety provided for sliding and overturning.
• Structural integrity ensured through bracing and anchoring.

Detailed technical specifications:

• Crane loads: Tables provided for CTT 181 and CTT 202 cranes under various wind conditions.
