At Brennan, we specialize in dam construction and repairs on navigational, hydroelectric, diversion, storage, detention, and earthen structures of all sizes. We work on every part of the dam, both above and below the waterline. Brennan crews have the experience and equipment necessary to work in a variety of conditions, including confined spaces, elevated work stations, underwater construction, and more. When most firms pursue dam work as a secondary focus, we have made it a primary focus with dedicated crews, specialized equipment, and a robust safety program.

A dam is a man-made barrier created by dam construction contractors over a watercourse that collects water behind it to form a reservoir. Dams serve many human needs, including irrigation, hydroelectric generation, lowering flood levels, and enhancing navigation. Dams also include auxiliary structures like:
To transport water to faraway locations, they are often linked to intake structures like canals, waterways, and pipelines. It is common practice to build a dam over a river to collect the water that flows into the valley behind it and store it in a reservoir. In certain cases, they are constructed across dry valleys or valleys with tiny streams to provide a reservoir for water brought in from elsewhere.
The land where the dam will be built must be made dry by rerouting streams and rivers. Usually, a tunnel or a channel is built around the dam&#;s side to redirect the flow of smaller rivers and streams. The path is shaped by excavating soft soils and rocks, while tougher rocks necessitate using explosives to blast away their surface.
At Gracon LLC, we specialize in rehabilitation, dam maintenance, construction, and replacement projects of all sizes. Our main capabilities include gate seals, welding, hydraulic hoist systems, and electricity.
Many people and groups are involved in planning and building a dam, making it a massive undertaking that requires the coordination of many distinct project management groups. Most large dams take years, if not decades, to complete because of the extensive planning and preliminary engineering processes.
The owner, either on their own or with the help of a licensed contractor, should set up a project organization once the planning and preliminary engineering phase has decided to proceed stage. This company will work with the property owner to produce the project&#;s preliminary plan, which includes determining which aspects of the project will be outsourced to third parties.
Contracting out the job of project engineering, general contractors, main equipment supply, and project construction allows each company to assemble a specialized project management team to oversee their assigned tasks. Information that this group must provide to the larger project management team to maintain cost and time constraints must be specified in the contract. This means that multiple project management teams will be needed for a dam of significant size.
Dams are incredible feats of engineering, able to hold large quantities of water for purposes such as flood control, hydroelectric power generation, and even recreational use. Have you ever wondered what went into the construction of the Hoover Dam?
Building a dam is a labor-intensive, time-consuming procedure that requires extensive manpower, supplies, and equipment. Some of the procedures involved in the Hoover Dam construction are listed below.

Rerouting the water: First, the land along the river where the dam will be constructed must be dewatered so that construction may begin. The engineers accomplish this by creating underground tube systems to reroute the water. The tunnels must be dug deep enough to collect rainwater and transport it underground. The river should be made shallow enough to work in, but not completely drained.
Laying the Dam&#;s Foundation: The first step in laying the foundation for the dam is to construct a cofferdam to redirect river water away from the tunnel is necessary if you haven&#;t already done so. The heaviest rocks should go at the bottom of the foundation stack, followed by the smaller rocks.
Constructing the primary framework: To stop water from leaking through the margins of the dam, you should compact the riverbed to remove any stray rocks and build a plinth (concrete base). After laying the foundation, the next phase of dam construction involves erecting the main structure on each side of the dam&#;s center. Reinforced concrete steel is commonly used in dam construction because of its durability against water.
Filling: After constructing the dam to the desired height, the reservoir must be filled. After the dam has been constructed, it is necessary to check its functionality (including the floodgates and valves) and observe its behavior.
Many essential functions for modern society rely on the services that dams provide, including safe drinking water, irrigation, flood prevention, generation of electricity, recreation, and more. The skilled builder contractors of Gracon are experts in constructing, repairing, and replacing mechanical components of dams of varying sizes. We also have the capacity to weld, as well as install, and repair gate seals and electric and hydraulic hoist systems.
Our method of building, installation, and rehabilitation is strongly rooted in our history and future as it was one of the early foundations of Gracon&#;s top dam construction enterprise. By providing these services, Gracon&#;s construction contractors have been able to learn about the market, set competitive rates for projects, and effectively address client concerns.
We also offer a range of industrial services including:
One of the top dam construction contractors companies, Gracon can create and install brand-new high-pressure slide gates, radial gates, crest gates, tainter gates, drum gates, and miter gates for dams.
By working on a wide variety of projects, the Gracon team has become one of the most knowledgeable and experienced in the country. Our highly skilled staff are able to tackle even the most technical issues associated with a dam&#;s inner workings because they have worked on projects identical to this for many years.
Our project exposure ensures you receive the most knowledgeable and experienced company in the US. Because the inner workings of a dam are complex, you need to trust this process with the experts. Contact us today!
