Commercial lease space renovation. Project: Image Studios, Beauty salon with individual rooms. 5,295 Sf Retail layout proposed. I mage Studios -individual Beauty Salons Wall Assembly This wall assembly's Sound Transmission Class (STC) would be around 35-45. The client stated that the units would have hair dryers and people talking loudly. The decibels for a hair dryer is between 70 and 90 decibels.  Loud taking would be between 60 and 70 decibels.  The decibels transmitting through the wall assembly would be 55 on the high side. The sound similar to 55 decibels would be a normal conversation between two people. So the client asked for an alternate wall assembly to reduce the sound. Proposed Wall Assembly We proposed a wall assembly that includes one layer of 5/8" GOLD BOND SOUNDBREAK XP on each side of the metal studs and resilient channels with 3-inch insulation. This STC rating is between 55 and 60. Proposed wall assembly between the units This assembly would then add 3...

An Energy Recovery Ventilator (ERV) can significantly reduce energy costs for a small commercial building in the southern United States by improving the efficiency of the HVAC (Heating, Ventilation, and Air Conditioning) system. Here are several ways an ERV achieves this:   # 1 Heat Exchange Efficiency ERVs transfer heat between incoming and outgoing air streams. In warm climates, they can cool incoming fresh air by transferring the heat to the outgoing stale air, reducing the load on the air conditioning system. This process helps maintain indoor comfort without requiring as much energy for cooling.   #2 Humidity Control In humid southern climates, ERVs also transfer moisture. They can reduce the humidity of incoming air by transferring moisture to the outgoing air, which reduces the need for dehumidification. This leads to lower energy consumption as the HVAC system doesn't have to work as hard to remove excess humidity.   #3 Reduced HVAC Load By pre-conditioning the in...

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 ad...

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 t...
