Tender Summary: Blank off Main Fire Line Pipe Due to Leaking Valve

Objectives

The primary objective is to isolate and secure the main fire line piping system at General Justice Gizenga Mpanza Hospital to address a leaking valve. The service aims to eliminate water leakage, restore system integrity, and ensure compliance with fire safety standards while preventing further damage to the hospital infrastructure.

Scope of Work

The scope includes the supply of all labour, materials, tools, and equipment necessary to blank off the main fire line. Key deliverables comprise:

• Conducting a mandatory site meeting to inspect the pipe and valve condition.
• Isolating the affected section of the fire line system.
• Preparing the pipe end for the installation of a blank-off fitting.
• Installing a durable blank-off mechanism to seal the pipe completely.
• Testing the installation to verify a leak-free seal.
• Restoring the work area to a clean and safe condition.

Technical Requirements

Service providers must adhere to the following technical specifications:

• Blank-off fittings must be compatible with the existing fire line material, diameter, and pressure rating.
• All components must be certified to withstand the operational pressure of the fire protection system.
• Workmanship must comply with relevant South African National Standards (SANS) for fire protection and plumbing.
• Materials must be new, undamaged, and fit for purpose.

Explanation of Terms: A "blank off" is a mechanical cap or plate used to seal the end of a pipe. In this tender, it refers to the process of capping the main fire line to permanently or temporarily block flow through the leaking valve section, thereby isolating the defect and stopping water loss.

Skills and Competency Requirements

Bidders must demonstrate the following capabilities:

• Qualified tradespersons with recognized certifications in plumbing, pipefitting, or fire protection engineering.
• Proven experience in executing blank-off procedures on pressurized fire line systems.
• Competence in using specialized tools for cutting, threading, or welding pipe ends as required.
• Adherence to strict health and safety protocols, including risk assessments for working within a healthcare facility.
• Ability to provide proof of competency and relevant trade test results upon request.
