Minimizing or Eliminating Assessments for Plumbing Replacements in Condo Buildings

Posted by Gary Westernoff at Thursday, February 22, 2024 Costing & Contracting 4 Comments 247

We have heard about condo association unit owners being assessed $30,000 to $50,000 dollars per unit to replace the plumbing in High rise condominium buildings.  This usually comes up when buildings are 50 years or older or as scheduled by the Homeowners Association’s reserve study. There are usually two thoughts when it comes to replacing anything in buildings:

“IF IT’S NOT BROKEN DON’T FIX IT” OR “BETTER TO BE SAFE THAN SORRY”

Here are a couple of consequences associated with plumbing failures in buildings:

1. Water damage that causes costly repairs; and
2. Increased insurance costs

 

 

The constructionplace.com solution

Here is Constructionplace.com’s solution for minimizing or eliminating these costly assessments. This approach not only saves lots of money but also minimizes overall disruption to the individual units and the building common areas during the work:

1. This approach allows plumbing replacement work to be completed over a period of time as individual units are upgraded or remodeled.
2. This approach encourages units’ owners to update or remodel their units because of the overall cost savings they will incur by using this management system; and
3. This approach ensures that the building’s minimum requirements for concealed building components are used and installed when the work is being completed.

Objectives

1. Minimize or eliminate plumbing replacement assessments in condominium high rise buildings.
2. Learn how your buildings plumbing system works for improving preventative maintenance procedures.
3. Whenever possible complete plumbing replacement work for adjacent units from remodeled units’ side to minimize disruption thus completing the work for two or three units at same time. Here is an example of a 10-year plumbing replacement project for a condominium building with 1013 units:

4. Purchase plumbing materials at Cost directly from the wholesaler for dramatic cost savings for installation by the respective                      contractors performing the work.

Understanding the Plumbing System in Buildings

There are two parts of a Building’s overall plumbing system, Sewer and Water Supply:

Water Supply – Our Definition of Water Supply as used herein is a piping system for bringing hot and cold water into a building supplying that water to various fixtures such as sinks, lavatories, toilets, showers and laundry appliances.

• PVC
• Copper
• Galvanized
• Black Iron for fire protection lines

Identifying Water Supply problems – Poor Water Pressure: Low water pressure is a tell-tale sign of severely corroded pipes. As corrosion builds up inside the pipe, water flow is drastically reduced to faucet sinks, showerheads and more.

Sewer – Our definition of Sewer as used herein is a piping system for removing wastewater from a building.

Building Sewer (BS): The building sewer is the main Drain, Waste and Venting system (DWV), which collects all of the building’s wastewater from the fixtures and appliances and directs the water and waste into the municipal sewer system.

And here are five components within a DWS the order of which they are installed in new buildings:

1. Building Drain (BD): The building drain is a horizontal pipe that runs underneath the building. This pipe is connected to the local municipal sewer system piping.
2. Waste Stack (WS): The waste stack is the DWV’s main vertical pipe inside the building. The waste stack receives all the discharge and directs it with flow to the building drain. The waste stack must always have a clean out at its base per code.
3. Stack Vent (VS): The stack vent is a dry piping system that continues from the waste stack to the roof releasing sewer gases. The diameter of the stack vent must be the same as the waste stack to work effectively.
4. Vent Stack (VS): This is the primary vent on a drain, waste and vent system. This vent size depends on the amount of discharge load throughout the building. Vent stacks are also required to have cleanouts at the base. The vent stack picks up all the lines in the building and redirects it to the stack vent to exit the building.
5. Cleanout (CO): The cleanout is designed to access the inside of the pipe in case anything goes wrong such as clogs.

 How do you know if plumbing systems needs to be replaced?

Warning Signs that Sewer Line Needs to Be Replaced

•  You Hear Gurgling Coming from the Pipes
• The Water Is Slowly Draining
• The Smell of Sewage Lingers
• The Toilet Bowl Water Level Is Up and Down

However, only defective or damaged pipes would be replaced or repaired during a piping repair or replacement project based on a survey or inspections.

Simple tips for Inspecting Pipes

• Look for signs of cracks.
• Check for leaks.
• Check for high or low water pressure.
• Look for signs of Cracks.
• Check for signs of corrosion – Corrosion is easily spotted through discoloration due to oxidation. If you previously painted your steel pipes, look for signs of paint chipping or splitting, can signify the start of corrosion.

 Investigation and Inspection Methods

Here a couple of those inspection methods:

• Ultrasonic (Non-Destructive) – Ultrasonic inspection uses sound reflections in order to determine pipe thickness and to locate defects in welds and materials. Ultrasonic testing has been widely accepted as the ideal technique for detecting corrosion in pipes, with phased array ultrasonic testing allowing for precise wall thickness measurements to help determine the presence of this otherwise hidden damage mechanism.
• Destructive Investigations – Open walls to expose the pipes to inspect.
• Camera Inspection (Non-Destructive) – Allows the plumber to see the inside of your pipes by attaching a small camera to the end of a snake and running it through the inside of your pipes. The camera then transmits the image, in real-time, to a nearby monitor in order to determine the problem and its location.
• Magnetic Particle Test – Magnetic particle testing is a non-destructive test method, which can be used to inspect a variety of ferromagnetic components and products. These include castings, forgings and weldments.

Inspection of Building Areas

Look at Existing Conditions – Divide the building into high and low use/occupancy areas by identifying climate exposure sides of the building   Weathering and exposure to harsh elements are cause for accelerated wear and cracking.

Entire Building – Based on the above randomly inspect units throughout the building.  Whenever, possible inspect units that at currently being remodeled or updated because these units most likely have exposed plumbing pipes.

Identify Remodeled Units – Identify units that have been remodeled or upgraded.  And if possible, find out the extent of any plumbing upgrades in the following areas:

• Kitchen
• Bathroom 1
• Bathroom 2
• Both

Material Options

Today Drain, Waste & Vent system (DWV) can be installed using three material types.  Most likely this material selection we be driven by the existing materials currently installed and the findings from your Investigation(s) mentioned above.

1. Polyvinyl Chloride (PVC)
2. Acrylonitrile Butadiene (ABS)

Both PVC and ABS are non‑toxic and resistant to abrasion. They are light in weight, affordable and easy to join and work with. And studies support that PVC is immune to corrosion, a minimum service life of at least 100 years can be expected.

3. Cast- Iron

Cast Iron pipe is commonly used, but it’s also a heavy material that requires equipment to cut the pipe and install it.  Cast iron, has a life span of 80 to 100 years.  There are two conventional methods of joining these pipes together:

• No-Hub Soil pipe
• Hub Soil pipe

Pipe Relining – Pipe relining is a process of repairing damaged or deteriorated pipes from the inside without the need for opening walls or excavation. Here are a few reasons why pipe relining may be worth it:

• Minimal disruption: Pipe relining is a minimally invasive process that involves inserting a liner into the damaged pipe eliminating mess, noise, and damage that come with opening walls excavation.
• Cost savings: Pipe relining is often more cost-effective than traditional pipe replacement because there is no need for opening large wall areas to expose the pipes and excavation, and the process can often be completed in a single day.
• Environmentally friendly: Pipe relining is an environmentally friendly solution because it reduces the amount of waste generated from wall removal debris, excavation and pipe replacement.

NOTE: Relining is a method used in lieu of replacing pipes and is primary ideal for piping in the ground and building where piping is exposed. And in our opinion the piping using the method should be free of corrosion and cracks.

 Project Management Suggestions

It is essential to establish the right team for your Plumbing replacement project, list all necessary activities and responsibilities, and of course set a budget. To set your budget you will need to Identify and Select the materials proposed for the project.

Sample Activities and Responsibilities

Sample Budget

 Identify and Select Materials

 

Purchasing Options for Cost Savings

• Purchase piping and fittings for stock and future delivery(s).
• Store at job site
• Store at warehouses)
• Assign to contractors.

Contracting and Phasing the Work

Performance Specifications – Create standard specifications for distribution to contractors performing work in the building (See Condo Performance Specifications below). This is important to ensure that the various contractors are installing acceptable components and materials in the building.

Pre-Qualify Contractors – Create an approved contractors list of Constructors for the General Managers and Unit Owners use. The following information is desirable for vetting purposes:

• Contact information.
• Licensing dates and expiration dates
• Insurance coverage, expiration dates and Certificates of Insurance
• Bonding Rate and Capacity (only if the project will be bonded)
• Terms such as Hourly rates, free estimates, service area, etc.
• Profile of completed Projects.
• Reviews

Here is the sharable Service Provider App available on constructionplace.com:

 

 

 

 

 

 

 

 

 

Master List of all condo units in Building – Create a master list of all units in the building by unit number.  Constructionplace.com offers a virtual app that allows the General Manager of the Building to list all units in the building with the ability to create a unique Project Directory for each unit:

 

 

 

 

 

Project Directory – Create a project directory for each unit in the building for identifying and communicating with the respective contractor working on the project. Constructionplace.com offers a virtual app that allows the respective Project Owners to add vetted Service Providers into a Project Directory for this purpose:

 

 

 

 

Phasing the Work – It is strongly suggested that the plumbing replacement work be phased and Completed with Units that are being upgraded and remodeled because:

• It may be possible to complete the work for the adjacent unit(s) for the remodeled unit’s side.
• It will save disruption to one of the units and reduce overall Plumbing replacement costs.

Other Work – Rough in for future AC condensate drain line to sewer system at the Kitchen Sink Drain.
