When it comes to addressing foundation issues, one of the most crucial documents you'll encounter is a detailed engineer's report. Moisture detection tools help prevent further foundation damage in homes foundation repair service market retaining wall. These reports are typically compiled by third-party engineers who provide an unbiased assessment of the problem. Understanding the key components of these reports is essential for interpreting their findings and making informed decisions.

Firstly, an engineer's report will usually begin with an **Executive Summary**. This section provides a high-level overview of the findings and recommendations. It's a quick snapshot that can help you understand the severity of the issue and the suggested course of action right from the start.

Following this, you'll find a detailed **Introduction** that outlines the purpose of the inspection, the date it was conducted, and the scope of work. This section might also include a brief history of the property and any previous repairs or issues.

The **Observations** or **Findings** section is where things get technical. Here, the engineer will describe in detail what they observed during their inspection. This can include cracks, settlement, upheaval, or other signs of foundation distress. Photographs and diagrams are often included to illustrate these points. It's crucial to review this section carefully to understand the extent and nature of the problem.

Next comes the **Analysis** section, where the engineer interprets their observations. They'll discuss the probable causes of the identified issues, such as soil movement, poor drainage, or construction defects. They might also provide insights into how these issues are impacting the structure as a whole.

The **Recommendations** section is where the engineer suggests steps to remediate the problem. This could include repairs, further monitoring, or additional investigations. Each recommendation is typically accompanied by a sense of urgency or priority level.

A section on **Cost Estimates** might also be included. While these are often rough estimates, they can give you a ballpark idea of what to expect financially. However, it's important to note that more accurate quotes should be obtained from contractors before proceeding with work.

Finally, the report will conclude with **Appendices** or **Attachments**. These can include anything from technical notes and calculations to copies of relevant documents or additional photographs.

To effectively interpret these reports, it's helpful to have some understanding of engineering terminology and concepts. Don't hesitate to ask for clarification from the engineer if needed. Remember, these reports are designed to provide you with objective information about your property's foundation-the more you understand about themmse reports

Interpreting structural analysis and recommendations provided by engineers for foundation repairs.


When it comes to addressing foundation issues, understanding the detailed reports provided by third-party engineers is crucial. These reports often contain a wealth of information derived from structural analysis, which is essential for making informed decisions about repairs. Interpreting these reports requires a blend of technical knowledge and practical understanding.

Firstly, it's important to grasp the language and terminology used by engineers. Terms like "differential settlement," "load-bearing capacity," and "shear strength" are common in these reports. Differential settlement, for instance, refers to the uneven sinking of a foundation, which can cause cracks and other structural issues. Understanding such terms helps in comprehending the severity of the problem and the urgency of repairs.

The structural analysis section of the report is particularly critical. This part typically includes diagrams, calculations, and explanations about the current state of the foundation. Engineers use these analyses to pinpoint areas of weakness, stress points, and potential failure zones. For example, if the analysis shows that a particular section of the foundation is experiencing excessive stress due to soil movement, it suggests that reinforcement or stabilization measures are necessary.

Recommendations from engineers are equally important. These usually include detailed steps for repairing the foundation, ranging from minor fixes like crack sealing to major interventions like underpinning or the installation of helical piers. Each recommendation comes with an explanation of why it is necessary and how it will address the identified issues. Understanding these recommendations involves not just reading the text but also visualizing how each suggested repair will impact the overall structure.

It's also essential to consider the cost implications and practicality of the recommended repairs. Engineers often provide multiple options with varying levels of complexity and expense. Balancing these factors against the long-term benefits is key. For instance, while a quick fix might be cheaper initially, it may not address the root cause, leading to more significant problems down the line. Conversely, a more costly but comprehensive repair could offer lasting stability and prevent future issues.

Collaboration with engineers is another vital aspect. Regular communication ensures that all stakeholders are on the same page regarding the scope of work, timelines, and expected outcomes. This collaborative approach helps in aligning expectations and avoiding misunderstandings or delays during the repair process.

In conclusion, interpreting detailed reports from third-party engineers involves understanding technical jargon, analyzing structural data, evaluating recommendations, and considering cost implications. Effective communication with engineers further ensures that foundation repairs are carried out efficiently and effectively, ensuring long-term structural integrity.

Evaluating soil conditions and their impact on foundation stability as outlined in the report.


Evaluating soil conditions and their impact on foundation stability is a critical aspect of interpreting detailed reports from third-party engineers. This process involves more than just reading numbers and graphs; it requires a nuanced understanding of geotechnical principles and how they apply to real-world construction scenarios.

When engineers compile these reports, they delve into the physical and chemical properties of the soil, such as its composition, moisture content, and compaction levels. These factors significantly influence how well a foundation will perform over time. For instance, clay-rich soils can expand and contract with changes in moisture, leading to potential instability if not properly managed. Conversely, sandy soils might be prone to erosion or settlement under certain conditions.

Understanding these characteristics allows us to anticipate potential issues before they become problems. A thorough evaluation includes examining the bearing capacity of the soil-its ability to support the weight of a structure without excessive settlement or failure. This is crucial because a foundation that settles unevenly can cause structural damage, such as cracks in walls or floors.

Moreover, engineers consider factors like groundwater levels and seasonal variations that could affect soil behavior over time. High groundwater levels can weaken the soil's stability, while seasonal changes can cause cycles of freezing and thawing that further complicate matters.

Interpreting these reports isn't just about looking at data points; it's about synthesizing this information into actionable insights. It's about ensuring that the design and construction phases are informed by these findings so that appropriate measures are taken to mitigate risks. This might include recommendations for specific types of foundations, such as piles or footings, depending on the soil conditions identified.

In essence, evaluating soil conditions is an integral part of ensuring foundation stability and overall project success. By carefully interpreting these detailed reports from third-party engineers, we can make informed decisions that balance safety, cost-effectiveness, and long-term structural integrity. It's a complex but essential task that underscores the importance of collaboration between various engineering disciplines to achieve robust structural solutions.

Analyzing the cost estimates and budget considerations based on the engineer's recommendations.


When dealing with complex construction or infrastructure projects, it's crucial to interpret detailed reports from third-party engineers accurately. These reports often contain a wealth of information, including technical specifications, risk assessments, and, most importantly, cost estimates and budget considerations. Understanding these financial aspects is vital for ensuring a project's feasibility and success.

Firstly, let's consider the cost estimates provided by engineers. These figures are typically broken down into various categories such as materials, labor, equipment, and contingencies. Each category comes with its own set of challenges; material costs might fluctuate due market conditions, labor costs can vary based on local regulations and skill levels, and equipment costs might be influenced by technological advancements or rental fees. Analyzing these estimates involves not just looking at the numbers but also understanding the context and potential variability behind them. For instance, if an engineer recommends a specific type of steel for structural integrity, it's essential to consider both its current cost and any foreseeable price changes due to market trends or supply chain issues.

Budget considerations go hand in hand with cost estimates but add an extra layer of complexity by factoring in financial constraints and allocation strategies. Engineers often provide recommendations that balance cost efficiency with quality and safety standards. Interpreting these recommendations requires a holistic approach, weighing short-term savings against long-term benefits or risks. For example, opting for cheaper materials might save money initially but could lead to higher maintenance costs down the line, impacting the overall budget negatively over time. Conversely, investing in high-quality materials might seem expensive initially but could offer substantial savings through reduced maintenance needs or enhanced longevity of structures-a critical point highlighted by engineers familiarized deeply within project specifications themselves ensuring optimal resource allocation throughout phases leading towards completion milestones effectively managed under real-world constraints faced during execution stages ensuring timely delivery within stipulated budgetary guidelines outlined during initial planning phase ensuring success metrics aligned goals achieved efficiently managing stakeholder expectations seamlessly integrating engineering insights derived actionable data points driving informed decision making process yielding desired outcomes successfully concluded projects exceeding benchmark performance indicators setting industry standards surpassed expectations delivering exceptional results sustaining long-term value appreciations establishing credibility reliability confidence among stakeholders fostering conducive environment promoting future collaborations leveraging synergistic partnership opportunities maximizing potential benefits derived collective efforts focused achieving common objectives ensuring sustainable development growth trajectory align strategic vision organizational goals societal benefits contributing positively transformative impact shaping future landscape achieving excellence setting precedence unparalleled achievements establishing legacy lasting impacts creating enduring legacies inspired generations fostering innovation driven progress transformative leadership guiding pathways future prosperity sustainable harmony balanced ecosystem ensuring holistic development inclusive growth equitable society empowered communities flourishing economy thriving environment harmonious coexistence enriching lives meaningful contributions inspiring journeys fulfilling dreams realizing aspirations unlimited potential infinite possibilities boundless horizons endless opportunities limitless potentialities empowering humanity embracing change adapting challenges overcoming obstacles achieving milestones celebrating accomplishments cherishing moments living dreams fulfilling purposes inspiring generations legacy enduring impacts transformative journey enriching lives meaningful contributions embracing humanity sustainable harmony thriving ecosystem balanced development empowered communities flourishing economy prosperous society nurturing environment holistic growth eq

Identifying potential legal implications and compliance requirements highlighted in the report.


When dealing with detailed reports from third-party engineers, it's crucial to go beyond just understanding the technical aspects; it's equally important to identify potential legal implications and compliance requirements. These reports often contain information that can have significant legal and regulatory consequences, making it essential for stakeholders to be well-informed.

Firstly, consider the legal implications of the findings. Engineers' reports might reveal issues such as structural deficiencies, environmental impacts, or safety hazards. These findings could lead to legal liabilities if not addressed promptly. For instance, if a report highlights a building code violation, ignoring it could result in fines, lawsuits, or even criminal charges. It's vital to consult with legal experts to understand the extent of these liabilities and how to mitigate them.

Secondly, compliance requirements are a critical aspect to scrutinize. Engineering projects often need to adhere to various regulations and standards set by local, state, or federal authorities. The report might point out areas where the project deviates from these standards. Ensuring compliance is not just about avoiding penalties; it's also about maintaining the integrity and safety of the project. Compliance might involve obtaining permits, conducting further assessments, or implementing corrective measures.

Moreover, environmental regulations are a significant area of concern. Engineers' reports may include assessments of environmental impact, waste management practices, or energy efficiency. Non-compliance with environmental regulations can lead to severe penalties and damage to reputation. Hence, it's essential to pay close attention to these aspects and ensure that all environmental standards are met or exceeded where possible...

Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics to solve its engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences.

Geotechnical engineering has applications in military engineering, mining engineering, petroleum engineering, coastal engineering, and offshore construction. The fields of geotechnical engineering and engineering geology have overlapping knowledge areas. However, while geotechnical engineering is a specialty of civil engineering, engineering geology is a specialty of geology.

History

[edit]

Humans have historically used soil as a material for flood control, irrigation purposes, burial sites, building foundations, and construction materials for buildings. Dykes, dams, and canals dating back to at least 2000 BCE—found in parts of ancient Egypt, ancient Mesopotamia, the Fertile Crescent, and the early settlements of Mohenjo Daro and Harappa in the Indus valley—provide evidence for early activities linked to irrigation and flood control. As cities expanded, structures were erected and supported by formalized foundations. The ancient Greeks notably constructed pad footings and strip-and-raft foundations. Until the 18th century, however, no theoretical basis for soil design had been developed, and the discipline was more of an art than a science, relying on experience.[1]

Several foundation-related engineering problems, such as the Leaning Tower of Pisa, prompted scientists to begin taking a more scientific-based approach to examining the subsurface. The earliest advances occurred in the development of earth pressure theories for the construction of retaining walls. Henri Gautier, a French royal engineer, recognized the "natural slope" of different soils in 1717, an idea later known as the soil's angle of repose. Around the same time, a rudimentary soil classification system was also developed based on a material's unit weight, which is no longer considered a good indication of soil type.[1][2]

The application of the principles of mechanics to soils was documented as early as 1773 when Charles Coulomb, a physicist and engineer, developed improved methods to determine the earth pressures against military ramparts. Coulomb observed that, at failure, a distinct slip plane would form behind a sliding retaining wall and suggested that the maximum shear stress on the slip plane, for design purposes, was the sum of the soil cohesion, , and friction , where is the normal stress on the slip plane and is the friction angle of the soil. By combining Coulomb's theory with Christian Otto Mohr's 2D stress state, the theory became known as Mohr-Coulomb theory. Although it is now recognized that precise determination of cohesion is impossible because is not a fundamental soil property, the Mohr-Coulomb theory is still used in practice today.[3]

In the 19th century, Henry Darcy developed what is now known as Darcy's Law, describing the flow of fluids in a porous media. Joseph Boussinesq, a mathematician and physicist, developed theories of stress distribution in elastic solids that proved useful for estimating stresses at depth in the ground. William Rankine, an engineer and physicist, developed an alternative to Coulomb's earth pressure theory. Albert Atterberg developed the clay consistency indices that are still used today for soil classification.[1][2] In 1885, Osborne Reynolds recognized that shearing causes volumetric dilation of dense materials and contraction of loose granular materials.

Modern geotechnical engineering is said to have begun in 1925 with the publication of Erdbaumechanik by Karl von Terzaghi, a mechanical engineer and geologist. Considered by many to be the father of modern soil mechanics and geotechnical engineering, Terzaghi developed the principle of effective stress, and demonstrated that the shear strength of soil is controlled by effective stress.[4] Terzaghi also developed the framework for theories of bearing capacity of foundations, and the theory for prediction of the rate of settlement of clay layers due to consolidation.[1][3][5] Afterwards, Maurice Biot fully developed the three-dimensional soil consolidation theory, extending the one-dimensional model previously developed by Terzaghi to more general hypotheses and introducing the set of basic equations of Poroelasticity.

In his 1948 book, Donald Taylor recognized that the interlocking and dilation of densely packed particles contributed to the peak strength of the soil. Roscoe, Schofield, and Wroth, with the publication of On the Yielding of Soils in 1958, established the interrelationships between the volume change behavior (dilation, contraction, and consolidation) and shearing behavior with the theory of plasticity using critical state soil mechanics. Critical state soil mechanics is the basis for many contemporary advanced constitutive models describing the behavior of soil.[6]

In 1960, Alec Skempton carried out an extensive review of the available formulations and experimental data in the literature about the effective stress validity in soil, concrete, and rock in order to reject some of these expressions, as well as clarify what expressions were appropriate according to several working hypotheses, such as stress-strain or strength behavior, saturated or non-saturated media, and rock, concrete or soil behavior.

Roles

[edit]

Geotechnical investigation

[edit]
Main article: Geotechnical investigation

Geotechnical engineers investigate and determine the properties of subsurface conditions and materials. They also design corresponding earthworks and retaining structures, tunnels, and structure foundations, and may supervise and evaluate sites, which may further involve site monitoring as well as the risk assessment and mitigation of natural hazards.[7][8]

Geotechnical engineers and engineering geologists perform geotechnical investigations to obtain information on the physical properties of soil and rock underlying and adjacent to a site to design earthworks and foundations for proposed structures and for the repair of distress to earthworks and structures caused by subsurface conditions. Geotechnical investigations involve surface and subsurface exploration of a site, often including subsurface sampling and laboratory testing of retrieved soil samples. Sometimes, geophysical methods are also used to obtain data, which include measurement of seismic waves (pressure, shear, and Rayleigh waves), surface-wave methods and downhole methods, and electromagnetic surveys (magnetometer, resistivity, and ground-penetrating radar). Electrical tomography can be used to survey soil and rock properties and existing underground infrastructure in construction projects.[9]

Surface exploration can include on-foot surveys, geologic mapping, geophysical methods, and photogrammetry. Geologic mapping and interpretation of geomorphology are typically completed in consultation with a geologist or engineering geologist. Subsurface exploration usually involves in-situ testing (for example, the standard penetration test and cone penetration test). The digging of test pits and trenching (particularly for locating faults and slide planes) may also be used to learn about soil conditions at depth. Large-diameter borings are rarely used due to safety concerns and expense. Still, they are sometimes used to allow a geologist or engineer to be lowered into the borehole for direct visual and manual examination of the soil and rock stratigraphy.

Various soil samplers exist to meet the needs of different engineering projects. The standard penetration test, which uses a thick-walled split spoon sampler, is the most common way to collect disturbed samples. Piston samplers, employing a thin-walled tube, are most commonly used to collect less disturbed samples. More advanced methods, such as the Sherbrooke block sampler, are superior but expensive. Coring frozen ground provides high-quality undisturbed samples from ground conditions, such as fill, sand, moraine, and rock fracture zones.[10]

Geotechnical centrifuge modeling is another method of testing physical-scale models of geotechnical problems. The use of a centrifuge enhances the similarity of the scale model tests involving soil because soil's strength and stiffness are susceptible to the confining pressure. The centrifugal acceleration allows a researcher to obtain large (prototype-scale) stresses in small physical models.

Foundation design

[edit]
Main article: Foundation (engineering)

The foundation of a structure's infrastructure transmits loads from the structure to the earth. Geotechnical engineers design foundations based on the load characteristics of the structure and the properties of the soils and bedrock at the site. Generally, geotechnical engineers first estimate the magnitude and location of loads to be supported before developing an investigation plan to explore the subsurface and determine the necessary soil parameters through field and lab testing. Following this, they may begin the design of an engineering foundation. The primary considerations for a geotechnical engineer in foundation design are bearing capacity, settlement, and ground movement beneath the foundations.[11]

Earthworks

[edit]

See also: Earthworks (engineering)

Geotechnical engineers are also involved in the planning and execution of earthworks, which include ground improvement,[11] slope stabilization, and slope stability analysis.

Ground improvement

[edit]

Various geotechnical engineering methods can be used for ground improvement, including reinforcement geosynthetics such as geocells and geogrids, which disperse loads over a larger area, increasing the soil's load-bearing capacity. Through these methods, geotechnical engineers can reduce direct and long-term costs.[12]

Slope stabilization

[edit]
Simple slope slip section.
Main article: Slope stability

Geotechnical engineers can analyze and improve slope stability using engineering methods. Slope stability is determined by the balance of shear stress and shear strength. A previously stable slope may be initially affected by various factors, making it unstable. Nonetheless, geotechnical engineers can design and implement engineered slopes to increase stability.

Slope stability analysis
[edit]
Main article: Slope stability analysis

Stability analysis is needed to design engineered slopes and estimate the risk of slope failure in natural or designed slopes by determining the conditions under which the topmost mass of soil will slip relative to the base of soil and lead to slope failure.[13] If the interface between the mass and the base of a slope has a complex geometry, slope stability analysis is difficult and numerical solution methods are required. Typically, the interface's exact geometry is unknown, and a simplified interface geometry is assumed. Finite slopes require three-dimensional models to be analyzed, so most slopes are analyzed assuming that they are infinitely wide and can be represented by two-dimensional models.

Sub-disciplines

[edit]

Geosynthetics

[edit]
Main article: Geosynthetics
A collage of geosynthetic products.

Geosynthetics are a type of plastic polymer products used in geotechnical engineering that improve engineering performance while reducing costs. This includes geotextiles, geogrids, geomembranes, geocells, and geocomposites. The synthetic nature of the products make them suitable for use in the ground where high levels of durability are required. Their main functions include drainage, filtration, reinforcement, separation, and containment.

Geosynthetics are available in a wide range of forms and materials, each to suit a slightly different end-use, although they are frequently used together. Some reinforcement geosynthetics, such as geogrids and more recently, cellular confinement systems, have shown to improve bearing capacity, modulus factors and soil stiffness and strength.[14] These products have a wide range of applications and are currently used in many civil and geotechnical engineering applications including roads, airfields, railroads, embankments, piled embankments, retaining structures, reservoirs, canals, dams, landfills, bank protection and coastal engineering.[15]

Offshore

[edit]
Main article: Offshore geotechnical engineering
Platforms offshore Mexico.

Offshore (or marine) geotechnical engineering is concerned with foundation design for human-made structures in the sea, away from the coastline (in opposition to onshore or nearshore engineering). Oil platforms, artificial islands and submarine pipelines are examples of such structures.[16]

There are a number of significant differences between onshore and offshore geotechnical engineering.[16][17] Notably, site investigation and ground improvement on the seabed are more expensive; the offshore structures are exposed to a wider range of geohazards; and the environmental and financial consequences are higher in case of failure. Offshore structures are exposed to various environmental loads, notably wind, waves and currents. These phenomena may affect the integrity or the serviceability of the structure and its foundation during its operational lifespan and need to be taken into account in offshore design.

In subsea geotechnical engineering, seabed materials are considered a two-phase material composed of rock or mineral particles and water.[18][19] Structures may be fixed in place in the seabed—as is the case for piers, jetties and fixed-bottom wind turbines—or may comprise a floating structure that remains roughly fixed relative to its geotechnical anchor point. Undersea mooring of human-engineered floating structures include a large number of offshore oil and gas platforms and, since 2008, a few floating wind turbines. Two common types of engineered design for anchoring floating structures include tension-leg and catenary loose mooring systems.[20]

Observational method

[edit]

First proposed by Karl Terzaghi and later discussed in a paper by Ralph B. Peck, the observational method is a managed process of construction control, monitoring, and review, which enables modifications to be incorporated during and after construction. The method aims to achieve a greater overall economy without compromising safety by creating designs based on the most probable conditions rather than the most unfavorable.[21] Using the observational method, gaps in available information are filled by measurements and investigation, which aid in assessing the behavior of the structure during construction, which in turn can be modified per the findings. The method was described by Peck as "learn-as-you-go".[22]

The observational method may be described as follows:[22]

  1. General exploration sufficient to establish the rough nature, pattern, and properties of deposits.
  2. Assessment of the most probable conditions and the most unfavorable conceivable deviations.
  3. Creating the design based on a working hypothesis of behavior anticipated under the most probable conditions.
  4. Selection of quantities to be observed as construction proceeds and calculating their anticipated values based on the working hypothesis under the most unfavorable conditions.
  5. Selection, in advance, of a course of action or design modification for every foreseeable significant deviation of the observational findings from those predicted.
  6. Measurement of quantities and evaluation of actual conditions.
  7. Design modification per actual conditions

The observational method is suitable for construction that has already begun when an unexpected development occurs or when a failure or accident looms or has already happened. It is unsuitable for projects whose design cannot be altered during construction.[22]

The concept of home improvement, home renovation or remodeling is the process of renovating, making improvements or making additions to one's home.[1] Home improvement can consist of projects that upgrade an existing home interior (such as electrical and plumbing), exterior (masonry, concrete, siding, roofing) or other improvements to the property (i.e. garden work or garage maintenance/additions). Home improvement projects can be carried out for a number of different reasons; personal preference and comfort, maintenance or repair work, making a home bigger by adding rooms/spaces, as a means of saving energy, or to improve safety.[2]

Types of home improvement

[edit]

While "home improvement" often refers to building projects that alter the structure of an existing home, it can also include improvements to lawns, gardens, and outdoor structures, such as gazebos and garages. It also encompasses maintenance, repair, and general servicing tasks. Home improvement projects generally have one or more of the following goals:[citation needed]

Comfort

[edit]
  • Upgrading heating, ventilation and air conditioning systems (HVAC).
  • Upgrading rooms with luxuries, such as adding gourmet features to a kitchen or a hot tub spa to a bathroom.
  • Increasing the capacity of plumbing and electrical systems.
  • Waterproofing basements.
  • Soundproofing rooms, especially bedrooms and baths.

Maintenance and repair

[edit]

Maintenance projects can include:

  • Roof tear-off and replacement.
  • Replacement or new construction windows.
  • Concrete and masonry repairs to the foundation and chimney.
  • Repainting rooms, walls or fences
  • Repairing plumbing and electrical systems
  • Wallpapering
  • Furniture polishing
  • Plumbing, home interior and exterior works
  • Shower maintenance

Additional space

[edit]

Additional living space may be added by:

  • Turning marginal areas into livable spaces such as turning basements into recrooms, home theaters, or home offices – or attics into spare bedrooms.
  • Extending one's house with rooms added to the side of one's home or, sometimes, extra levels to the original roof. Such a new unit of construction is called an "add-on".[3]

Saving energy

[edit]

Homeowners may reduce utility costs with:

  • Energy-efficient thermal insulation, replacement windows, and lighting.
  • Renewable energy with biomass pellet stoves, wood-burning stoves, solar panels, wind turbines, programmable thermostats,[4] and geothermal exchange heat pumps (see autonomous building).

Safety, emergency management, security and privacy

[edit]

The need to be safer or for better privacy or emergency management can be fulfilled with diversified measures which can be improved, maintained or added. Secret compartments and passages can also be conceived for privacy and security.

  • Interventions for fire protection and avoidance. Possible examples are fire sprinkler systems for automatic fire suppression, smoke detectors for fire detection, fire alarm systems, or passive fire protection (including some wildfire management strategies).
  • Technical solutions to increase protection from natural disasters, or geotechnical and structural safety (e.g. hurricane or seismic retrofit).
  • Interventions and additions to increase home safety from other hazards, like falls, electric injuries, gas leaks or home exposure to environmental health concerns.
  • Physical security measures:
    • Access control systems and physical barriers, which can include fences, physical door and window security measures (e.g. grilles, laminated glass, window shutters), locks;
    • Security lighting, security alarms and video surveillance.
  • Safes and vaults.
  • Spaces for emergency evacuation, like emergency exits and rarer escape tunnels.
  • Spaces which provide protection in the event of different emergencies: areas of refuge, storm cellars (as protection from tornadoes and other kinds of severe weather), panic rooms, bunkers and bomb shelters (including fallout shelters), etc.
  • Home renovations or additions used to increase privacy can be as simple as curtains or much more advanced, such as some structural surveillance counter-measures. They may overlap with physical security measures.
  • Public utility outage preparedness, like backup generators for providing power during power outages .

Home improvement industry

[edit]

Home or residential renovation is an almost $300 billion industry in the United States,[5] and a $48 billion industry in Canada.[6][full citation needed] The average cost per project is $3,000 in the United States and $11,000–15,000 in Canada.

Professional home improvement is ancient and goes back to the beginning of recorded civilization. One example is Sergius Orata, who in the 1st century B.C. is said by the writer Vitruvius (in his famous book De architectura) to have invented the hypocaust. The hypocaust is an underfloor heating system that was used throughout the Roman Empire in villas of the wealthy. He is said to have become wealthy himself by buying villas at a low price, adding spas and his newly invented hypocaust, and reselling them at higher prices.[7]

Renovation contractors

[edit]

Perhaps the most important or visible professionals in the renovation industry are renovation contractors or skilled trades. These are the builders that have specialized credentials, licensing and experience to perform renovation services in specific municipalities.

While there is a fairly large "grey market" of unlicensed companies, there are those that have membership in a reputable association and/or are accredited by a professional organization. Homeowners are recommended to perform checks such as verifying license and insurance and checking business references prior to hiring a contractor to work on their house.

Because interior renovation will touch the change of the internal structure of the house, ceiling construction, circuit configuration and partition walls, etc., such work related to the structure of the house, of course, also includes renovation of wallpaper posting, furniture settings, lighting, etc.

Aggregators

[edit]

Aggregators are companies that bundle home improvement service offers and act as intermediary agency between service providers and customers.

[edit]

Home improvement was popularized on television in 1979 with the premiere of This Old House starring Bob Vila on PBS. American cable channel HGTV features many do-it-yourself shows, as does sister channel DIY Network.[8] Danny Lipford hosts and produces the nationally syndicated Today's Homeowner with Danny Lipford. Tom Kraeutler and Leslie Segrete co-host the nationally syndicated The Money Pit Home Improvement Radio Show.

Movies that poked fun at the difficulties involved include: Mr. Blandings Builds His Dream House (1948), starring Cary Grant and Myrna Loy; George Washington Slept Here (1942), featuring Jack Benny and Ann Sheridan; and The Money Pit (1986), with Tom Hanks and Shelley Long. The sitcom Home Improvement used the home improvement theme for comedic purposes.

Very happy with my experience. They were prompt and followed through, and very helpful in fixing the crack in my foundation.

USS was excellent. They are honest, straightforward, trustworthy, and conscientious. They thoughtfully removed the flowers and flower bulbs to dig where they needed in the yard, replanted said flowers and spread the extra dirt to fill in an area of the yard. We've had other services from different companies and our yard was really a mess after. They kept the job site meticulously clean. The crew was on time and friendly. I'd recommend them any day! Thanks to Jessie and crew.

It was a pleasure to work with Rick and his crew. From the beginning, Rick listened to my concerns and what I wished to accomplish. Out of the 6 contractors that quoted the project, Rick seemed the MOST willing to accommodate my wishes. His pricing was definitely more than fair as well. I had 10 push piers installed to stabilize and lift an addition of my house. The project commenced at the date that Rick had disclosed initially and it was completed within the same time period expected (based on Rick's original assessment). The crew was well informed, courteous, and hard working. They were not loud (even while equipment was being utilized) and were well spoken. My neighbors were very impressed on how polite they were when they entered / exited my property (saying hello or good morning each day when they crossed paths). You can tell they care about the customer concerns. They ensured that the property would be put back as clean as possible by placing MANY sheets of plywood down prior to excavating. They compacted the dirt back in the holes extremely well to avoid large stock piles of soils. All the while, the main office was calling me to discuss updates and expectations of completion. They provided waivers of lien, certificates of insurance, properly acquired permits, and JULIE locates. From a construction background, I can tell you that I did not see any flaws in the way they operated and this an extremely professional company. The pictures attached show the push piers added to the foundation (pictures 1, 2 & 3), the amount of excavation (picture 4), and the restoration after dirt was placed back in the pits and compacted (pictures 5, 6 & 7). Please notice that they also sealed two large cracks and steel plated these cracks from expanding further (which you can see under my sliding glass door). I, as well as my wife, are extremely happy that we chose United Structural Systems for our contractor. I would happily tell any of my friends and family to use this contractor should the opportunity arise!

USS did an amazing job on my underpinning on my house, they were also very courteous to the proximity of my property line next to my neighbor. They kept things in order with all the dirt/mud they had to excavate. They were done exactly in the timeframe they indicated, and the contract was very details oriented with drawings of what would be done. Only thing that would have been nice, is they left my concrete a little muddy with boot prints but again, all-in-all a great job

What a fantastic experience! Owner Rick Thomas is a trustworthy professional. Nick and the crew are hard working, knowledgeable and experienced. I interviewed every company in the area, big and small. A homeowner never wants to hear that they have foundation issues. Out of every company, I trusted USS the most, and it paid off in the end. Highly recommend.
