The Importance of Shop Drawings Reviewed By Architects

The Importance of Shop Drawings Reviewed By Architects

The Importance of Shop Drawings Reviewed By Architects should never be discounted. Many companies turn their shop drawings over to low-level staff members to review, yet doing so is often a mistake. It is best to allow an architect to review these documents, as doing so allows potential problems to be discovered early in the process. This helps to keep costs down for the contractor and helps to ensure he or she receives fair compensation for the job. If a problem is detected after work has begun, he or she is typically responsible for the cost overruns. This third party is often more objective and can see things those close to the project may overlook.

Companies often worry about taking this step simply because they don’t want to admit there was a design flaw to the client. The key to doing so without losing the client’s confidence is to identify the problem and provide potential solutions. This is less painful than completing the project only to find a problem is present and the system is flawed in one or more ways. The client definitely will not be happy in this situation.

The Contract Submittal Process For Shop Drawings

First and foremost, only submit those documents outlined in the contract that are required for review. The architect will review those documents, returning others without touching them. The contractor is the sole person who may submit these documents, as opposed to subcontractors or vendors. The general contractor is the one who coordinates the project, thus he or she needs to review the drawings. In addition, he or she sets the schedule for the project and the architect needs to adhere to it, taking into account the possible need for a resubmittal. Following the submittal process helps to keep the project on track. Finally, the contractor must ensure submittals meets specifications or the architect will return them to the contractor, which delays the process.

The architect examines these documents to ensure they conform with the design concept outlined in construction documents. They aren’t approving the means of construction, the method, the techniques, procedures, or sequences. Nor are they responsible for approving safety precautions.

Types of Submittals

The action submittals are those which require responsive action on the part of the architect and contain written and graphic information. Shop drawings fall under this category as do design submittals.

The information submittals are ones which don’t require approval from an architect. They only include written information and might be rejected in the event they don’t meet requirements. This includes certificates, supplier reports, and source quality control submittals.

Closeout submittals are required and cover everything from operation and maintenance manuals, record documents, and extra materials to submittal of warranties and bonds.

Maintenance material submittals are likewise required and include spare parts, tools, and extra stock materials.

The construction submittal process needs to be followed carefully to reduce risks for all parties. In addition, it must be monitored and managed at all times to detect problems and costly mistakes along with any risk of personal injury. However, changes to the shop drawings don’t override contract documents that have already been approved. Be aware that the architect must issue a change order or approved changes in the work or construction change directive before the contractor can legally disregard the contract and follow the architect’s directions. The contractor must ultimately comply with the contract documents, thus any changes made following the submittal of shop drawings or other documents must be updated in the contract.

The process tends to be time-consuming, so individuals involved need to ensure they are following the process exactly. Any delays in the submittal process can lead to delays in completion of the project, and this negatively reflects on all parties involved. In the event there are questions, they need to be addressed immediately to ensure other issues don’t arise.

What is Steel Sheet Piling and What Types Are Available?

What is Steel Sheet Piling and What Types Are Available?

Walls are often needed to retain water or soil, and many builders opt to make use of steel sheet piles for this purpose. These long structural sections make use of a vertical interlocking system to create one continuous wall, and the ability of each section to perform its function depends on the soil underneath the section and the geometry. This is due to the sheet pile transferring pressure from the wall’s high side to the soil located in front of the wall. The wall created may either be permanent or temporary. What is Steel Sheet Piling and What Types Are Available?

What Is Steel Sheet Piling?

Steel sheet piling is made using either cold formed or hot rolled manufacturing processes, and the process used determines the type of interlock. With hot-rolled piles, the steel is produced at a high temperature, and this results in a tight interlock. The cold-formed method, in contrast, created a looser interlock, and this is of importance. Walls requiring low permeability and those to be used in hard driving conditions need to be of the hot rolled variety to withstand the surrounding conditions. This is the major difference between the two options.

What Is Steel Sheet Piling Used For?

One of the most common applications for steel sheet piles is to support excavations. Many users find this option viable when they wish to create a barrier to groundwater flow, and bulkheads and seawalls often make use of the piles in the construction process. In fact, these piles are of great help in any project that is constructed below grade leading to the need for a retention wall. There are numerous other applications for this material, and steel sheet piles may be found in cofferdams, parking garages, and more, as they are extremely versatile and easy to use.

Why Steel Sheet Piling?

Installation stresses often lead to the early failure of retention wall materials. These sheets are driven into the ground and are highly resistant to the driving force thanks to their strong joints.

The material is both recyclable and reusable.

Pile length can be easily adapted to meet the requirements of the project, and the steel may be welded or bolted when needed.

Very little maintenance is needed, and the material holds up both under water and above.

The piles are lightweight, thus they are easy to handle, lift, and transport.

Different Types Of Steel Sheet Piling

Short walls with a light load benefit from the use of pan type sheet piling. These cold formed piles are of a smaller size than other piling options, thus this is their main purpose. Individuals building a drainage ditch, homeowners wanting to construct a retaining wall, and golf course owners often choose this piling material.

Z type sheet piling is easily recognizable thanks to its horizontally stretched Z shape. What distinguishes z type sheet piling from other types is the location of the interlocks. They are located as far as physically possible away from the neutral axis, as this increases the pile’s strength-to-weight ratio and its shear transmission. Thanks to these features, the Z type sheet piling is the most commonly seen in the country. This type of piling is commonly found in environmental barrier walls, parking garages, and retaining walls.

Certain applications require the use of a unique solution, and this is where flat web sheet piling becomes of great help. These piles come in circles and arcs that form gravity cells, while most piles make use of their stiffness or bending strength to retain water or soil. The gravity cells are joined together through the interlock tensile strength. In fact, the two major design characteristics of this piling are the allowable lock rotation and the lock tensile strength. Applications of great height or diameter typically make use of this piling option, as it can withstand high pressure.

What makes u type sheet piling different from Z type sheet piling is the location of the interlock. With the U pile, the interlock is located on the neutral axis, The centerline placement of the lock leads to problems with shear transfer, thus purchasers need to carefully determine if this is the right option for their needs.

Individuals who need more information about steel sheet piling, its uses, and applications for each type should contact Frank Mullaney at The Beacon Projects. Mr. Mullaney has more than 40 years in the construction industry and has extensive knowledge of building materials, their applications, and more.

Why Does a Foundation Need Footing Drains?

Why Does a Foundation Need Footing Drains?

Water accumulating around the perimeter of a foundation can lead to damage, thus building codes across the United States now require the installation of footing drains. These drains function to divert water away from the foundation and are easy to install when the structure is being built. When there is no footing drain present or the one in place fails, the system needs to be fixed in a timely manner before problems arise. However, many homeowners aren’t even aware this system is present and have numerous questions when they discover this is the case. One question comes up again and again: Why Does a Foundation need Footing Drains?

What Is A Foundation Drainage System?

Contractors install foundation drains around the perimeter of a structure to divert water away from the foundation. The drain system helps to eliminate hydrostatic pressure around the perimeter of the building and stops water from entering the basement. Foundations are constructed using porous materials, and water left standing around these materials will be absorbed over time. Standing water, often referred to as perched water or a high water table, leads to wet basements and a whole host of issues.

The Dangers Of Wet Basements

Wet basements often lead to the development of mold, mildew and their accompanying musty smell. In addition, a wet basement has a negative impact on air quality and may also lead to health problems for occupants of the home. Furthermore, what many property owners fail to realize is a wet basement can bring about moisture issues in the attic.

Drainage System Components

The average foundation drainage system has three components. A high-density polyethylene plastic pipe is the first component. The pipe is approximately four to six inches in diameter and is perforated to allow water to enter the pipe and be carried away from the home. The pipe needs to be a contiguous system and be designed with the lot’s slope in mind. This pipe is placed on gravel and filter fabric and the fabric is then folded over the trench. More stone is added, and sand is placed on top of these items to ensure the soil doesn’t wash into the material and clog the drain pipe. Once water enters the pipe, it must be transported away from the foundation. That leads to the third component of foundation drain systems: a delivery system. This system may include a sump pump, an off-site storm water system, or an on-site dry well.

Why Do Foundation Drains Fail?

A foundation drain may fail for a number of reasons. The vast majority of systems are installed when the home is built, and time takes its toil on the system. Soil movements and pressure can have a negative impact on the system, and there is no way to know how the original contractor completed the installation. They may have used debris from the site to backfill the foundation or they may have neglected to compact or tamp the backfill. Both can impact the longevity of the system. When installing a new foundation drain, it helps to know why the previous one failed.

Property owners in need of a new foundation drain should contact The Beacon Projects Group and LEED AP Frank Mullaney. This company has earned a reputation for managing projects carefully, effectively, and responsibly. They adhere to the budget and ensure the project stays on schedule while meeting regulatory commitments.
