What is your Warranty on your Metal Wall panels? Is it fading?

Metal Wall Panel Warranty


We completed a custom house for a client, and he requested to have maintenance free metal wall panels on the exterior of his house. He wanted a Wow-type color that would stand out. 

He selected the Hawaii Blue from Lehman. 

I investigated this color because I was concerned about the fading that may occur. You see in the following photo that his next-door neighbor had fading on his garage,



In reviewing the following chart, you will see that bold colors like Colonial Red and Regal Blue have a low SRI number. SRI is the Solor Reflective Index number. These colors absorb the sun's heat and will break down the color pigments. 
Whereas the lighter colors will reflect the sun's energy. 



In selecting the Hawiian Blue color I investigated the Paint Warranty from Lehman.

They indicate a 40-year limited warranty on their painy. And the limited warranty is as follows;

They will provide coverage within 30 years and if the panels have a chalking over a number 8 on vertically installed sidewall panels. The fading does not change more than 5 Hunter delta E units for the vertically installed panels. 

Caulking is shown below. As you see you there is virtually no chalking. 


The fading is a Delta 5 as shown below. This colored panel was deemed acceptable by the owner for the exterior wall panels.

This is a silicone polyester paint and is an economical alternative to the more expensive Kynar 500 paint. The Kynar 500 paint is a resin paint and it has the same 30-year warranty in chalking, a number 8 and fading, a Delta 5.

When is it good to use the Design-Build Method on Construction Projects?

The Design-build method on your construction project versus the traditional Design, bid, build method. Project: Huntsman Chemical Computer Building Addition, Conroe, Texas  I met Huntsman in mid-August and reviewed their completed drawings for the project.   They required that their project be complete by December 1 st . Their design showed a 44’ x 40’ painted block addition, one story along with bar joists and a structural steel deck with poured concrete and a gable steel frame roof with metal roof panels.                                  Bar joists with metal deck and poured concrete deck. METAL BAR JOISTS SCHEDULE PROBLEM Bar joists require a 10–12-week delivery after the shop drawing review. This puts the delivery in early December. Their design is a 7-month schedule project, not the 3 months that they desired. REDESIGN OF THE PROJECT TO A STRUCTURAL STEEL FRAMING I discussed with them that they would have to change the design to a structural steel beam design instead of the bar

The Design-Build Method is an alternative in the building of your project.  In the Design-Build method, you will start an immediate collaboration with your Design-Build consultant (DBC) The Pre-Construction activities are the first part of the Design-Build Method. The pre-construction phase starts with a Preliminary drawing or sketch that can be generated by the Design-Build consultant or the Owner. Develop Estimates and Budgets From there, you want to establish the Budget of the project from the design stage through the construction stage. The DBC team will start with square foot estimates. As more detailed drawings are completed by the  D BC, they will develop a more detailed construction estimate.   Incorporate Value Engineering into your  project. At this point, the DBC will develop some Value engineering suggestions and Options for the building. The Value Engineering suggestions would look at alternate materials, methods, and components in the design that can add value and reduce

Notices of Nonperformance to a Trade Contractor on a construction project

  Bridgewater College Dormitory Project Let me give you an example of an underperforming contractor from one of my past projects. I was involved in the building a $2.7 million Bridgewater Dormitory on the Campus of Bridgewater University in Bridgewater, Virginia. The Structure is 3 stories with a basement. Bridgewater Dormitory Liquidated Damage Project This was a liquidated damage clause project. The project had to be completed before the school year started in late August. Liquidated Damages clause means that if we go over the allotted time for the project then we would be charged a specific amount for each day that we were over the time limit. So,  the overall schedule of this project was very critical to the completion of the project. The critical path of this project was the construction of the exterior masonry work which included the brick and the Capstone on the top of the building. Every Trade Contractor is tied to the overall schedule of the project and the completion date.
