1. Compliance with submission of all mandatory returnable documents. 2. Joint venture submissions must include formalised agreements with signed pages, detailing ownership, control, and work allocation. 3. Technical capacity assessed via Method Statement (T2.1.20) and Plant/Equipment List (T2.1.21). 4. Financial standing and B-BBEE status will be evaluated. 5. Local content (SBD6.2) and subcontracting plans (T2.1.18) may be considered if applicable.

The project is the raising of Tzaneen Dam, part of the Groot Letaba River Water Development Project (GLeWaP) to enhance water resources for the Mopani District, Limpopo. It is being developed by the Department of Water and Sanitation (DWS) through implementation agent Lepelle Northern Water, in tandem with construction of the new Nwamitwa Dam. The dam raising aims to increase assurance of yield.

While explicit commercial eligibility criteria (e.g., B-BBEE, CIDB rating) are not stated in this BLRA document, contractors must demonstrably meet the following operational/safety criteria to be considered capable: 1. Proven ability to implement and manage the extensive health and safety controls outlined. 2. Access to and competence in using the required specialized equipment (drill rigs, cranes, concrete pumps). 3. Employment of personnel with verified competencies and medical fitness for the tasks. 4. A history of compliance with OHS Act and Construction Regulations. 5. Ability to conduct detailed task-specific risk assessments and integrate them into work methods.

The project involves raising Tzaneen Dam by 3m to increase gross storage from 157.3 million m³ to 193 million m³. Key works include: demolition of approximately 4m of concrete from the existing Ogee crest; construction of a reinforced concrete labyrinth to a new crest elevation of RL 726.99m; raising of concrete NOC tongue wall sections; modifying the inlet works control house for impermeability; raising and strengthening embankment NOCs to RL 732.3m; and revising energy dissipation measures. The dam is a concrete gravity spillway with earthfill embankments, located on the Groot Letaba River upstream of Tzaneen, Limpopo. It was completed in 1977, is classified as Category III (Large size, High hazard potential), and registered under Dam Safety Legislation.

Maintain high standards of housekeeping and appoint a stacking and storage supervisor. Conduct monthly inspections on stacking and storing. Ensure competent/registered electricians conduct temporary electrical installations and issue Electrical Certificates of Compliance (COC). Conduct pre-start inspections, ensure good operator visibility, adhere to speed limits, provide proper supervision, and use water trucks for dust suppression. For lifting operations: ensure cranes are load tested, conduct daily pre-start inspections, and only allow competent operators. For drilling: conduct visual inspections, use drip trays and spill kits, adhere to maintenance schedules, and use only certified competent operators. Inspect equipment monthly and report deviations. Erect scaffolding in accordance with SANS 10085, conduct daily inspections by a competent person, and ensure safety harnesses are worn and in good condition. For welding: ensure flashback arrestors are fitted, conduct task-specific training, issue welding helmets and correct PPE, and conduct monthly inspections on welding machines.

The contractor must comply with Occupational Health and Safety Act requirements, including conducting baseline risk assessments. Key compliance points: ensure all responsible personnel submit CVs and have legal appointment letters signed prior to work commencement; verify competencies; conduct occupational medicals before work starts; provide site-specific induction training; appoint a Risk Assessor with a HIRA certificate; implement task-specific risk assessments; maintain attendance registers; use method statements/Safe Operating Procedures; ensure all contractors develop effective controls for high and critical risk scenarios; and communicate the Baseline Risk Assessment to all construction partners.

This is a Baseline Risk Assessment prepared per Construction Regulation 5(1)(a) of the Occupational Health and Safety Act. The objective is to identify and categorise hazards associated with tasks during different work categories to assist management in eliminating, minimising, or controlling risks. The assessment must be reviewed periodically (about every year, after incidents, or changes in workforce/equipment). The risk analysis method includes describing tasks, evaluating probability and severity of risks, and evaluating controls. Risk levels are defined: Low (1-6), Medium (7-15), High (16-25). Consequence ratings range from medical treatment only (1) to fatality/permanent disability (5). Probability ratings range from very unlikely (1) to common occurrence (5). High-risk activities require immediate attention; training is often a solution. The hierarchy of control must be applied. Basic PPE required: hard hat, overalls, ear protection, dust mask, safety vest, safety glasses, safety footwear, gloves, fall protection equipment. References required: method statement, SDS, planned task observation, safe work procedure, work instruction, transmittable disease control, daily safety task instruction. Specific control measures are listed for numerous activities including project mobilization, site establishment, vehicle operations, excavations, lifting, drilling, concrete works, scaffolding, working at heights, handling hazardous chemical agents, hot work, electrical works, working near water, brickwork, demolition, and site demobilization.

The risk assessment considers environmental impact as part of the consequence evaluation, where events may cause environmental impact.

The contractor must manage legal liability risks. Key requirements: ensure legal appointment letters are signed prior to work commencement; verify competencies; refer to design drawings for underground services; plan work to avoid overhead power lines; use pre-start checklists; appoint competent, medically fit operators; supervise work; use banksmen/spotters; appoint a Demolition Work Supervisor; ensure no person works in an area not declared safe; and have a watchman present during demolition by machinery.
