Big construction projects in Knoxville don’t get built in one shot. They happen in stages, and a construction survey helps make sure each stage lines up with the one before it. When that step gets skipped or rushed, problems build up between phases and end up costing a lot more to fix than anyone planned for.

Why Multi-Phase Construction Projects Require More Than One Survey Schedule

Big projects get split into stages because doing everything at once isn’t realistic. Roads go in first, then utilities, then buildings, and the finishing work comes last. Each stage needs its own survey work because the ground changes a lot between phases, and old data doesn’t always match what’s sitting on the site months later.

Grading moves dirt around, temporary structures go up and come down, and crew access points shift depending on where work is happening. A survey done at the start of the project can be outdated by the time phase three rolls around. Checking the survey at key points along the way keeps each stage grounded in what’s actually there, not what things looked like a year ago.

How Survey Control Points Help Keep Separate Project Phases Connected

Control points are fixed spots set up across the site that every phase measures from. They work like a shared reference so that a building going up in phase three actually lines up with the road built in phase one. Without them, each phase drifts a little, and small drifts turn into big problems when the last phase has to connect with everything else.

Surveyors use control points throughout the whole project, not just at the beginning. They check them when laying out new buildings, placing utilities, and setting roads and parking areas. If a site disturbance wipes out a control point and nobody replaces it, getting the project back on track takes extra time and money that wasn’t budgeted for.

Why Temporary Access Roads and Work Areas Need Accurate Placement

Temporary features don’t seem like a big deal because they’re not permanent, but where they go matters more than most people think. A staging area in the wrong spot can block access to a section of the site that needs to stay active in the next phase. A temporary road placed too close to planned underground utilities means moving it later, which slows everything down.

Some temporary features also end up close to where permanent ones will go. A construction entrance often sits near where the final driveway will be built. Getting the temp layout right from day one means the site is already set up for what comes next, and the crew doesn’t have to stop and rework things that should have been placed correctly the first time.

How Construction Survey Data Supports Changes During Long-Term Projects

Plans change on long projects. A building footprint moves a few feet to avoid hitting a utility line. A road gets shifted after a grading problem shows up. A parking area gets bigger after the city asks for more spaces. Every one of those changes needs updated survey data before the crew can keep going.

When the survey stays current, changes are easy to manage. The crew builds from the right plan, not an old version that no longer matches what’s approved. On a project that runs two or three years, having accurate and updated site data keeps each phase from running into problems caused by changes that happened earlier in the build.

Why Final Improvements Must Fit With Earlier Construction Phases

The last phase is where everything has to come together, and that’s where small errors become really obvious. Sidewalks need to meet curb cuts that were set months ago. Landscaping has to work around utility covers from phase one. Parking stripes have to fit the lot dimensions set when grading was done. If the final crew doesn’t have accurate survey data connecting their work to earlier phases, things won’t line up.

Fixing those misalignments at the end of a project is expensive and slow. A sidewalk that misses its connection point means tearing up fresh concrete. A utility cover in the wrong place means rerouting it or redoing the landscaping around it. Good survey work through the final phase catches these issues before they become visible problems, and the project finishes clean instead of with a list of corrections to sort out.

FAQ

What is a multi-phase construction project?
It’s a project built in separate stages, with each stage finishing part of the work before the next one begins.

Why are construction surveys needed throughout the project?
The site changes a lot between phases, and early survey data often doesn’t reflect current ground conditions by the time later stages start.

What are survey control points?
They’re fixed reference spots set across the site that keep measurements consistent from one phase to the next.

Can construction plans change during a multi-phase development?
Yes, changes happen often, and updated survey data makes sure those changes get built correctly without creating conflicts with work that’s already done.

How do construction surveys help keep large projects organized?
They give every phase accurate reference information so the work connects properly from start to finish.

A Land Surveyor is essential whenever you plan on building a house, buying or selling a property, or dividing your property amongst your children. Many land surveyor made it down to history.

In fact, three of the four faces carved in Rushmore are land surveyors (Presidents George Washington, Thomas Jefferson and Abraham Lincoln were all three surveyors, Teddy Roosevelt was not.).

Others popular names were Daniel Boone, Meriwether Lewis and William Clark (Lewis & Clark), Sir George Everest, Charles Mason & Jeremiah Dixon (of the Mason-Dixon Line fame) and author Henry David Thoreau practiced for a time in Concord, Massachusetts.

What is a Land Surveyor?

Aland surveyoris a person with the academic qualifications and technical expertise to measure and plot the lengths and directions of boundary lines and the dimensions of any portion of the earth’s surface (including natural and other structures). That definition is quite a mouthful, but in actuality the field of surveying (geomatics) includes many other facets.

If you plan to purchase a lot, build your dream house, divide your property to your children, or simply want to know the details of a land property, a land surveyor is the best person to help you out. A land surveyor locates theboundaryof your property and the location of your home within that boundary to determine if there are any encroachments by your neighbors onto you or vice versa. Common encroachments are fences, driveways, etc.

These days a land surveyor in the United States is regulated and licensed by the various state governments. In Tennessee, theTennessee State Board of Licensure for Professional Engineers and Land Surveyorswas established in 1935 to protect the public.  A land surveyor’s duty is “to safeguard life, health, and property, and to promote the public welfare by providing for the licensing and regulation of persons in the practices of engineering and land surveying. This purpose is achieved through the establishment of minimum qualifications for entry into the professions of engineering and land surveying, through the adoption of rules defining and delineating unlawful or unethical conduct, and through swift and effective discipline for those individuals or entities who violate the applicable laws or rules.”

How to become a land surveyor?

As of 2007, a newly licensed land surveyor is required to finish a four year degree in surveying or a closely related field, a four to eight years of on-the-job training under a licensed practicing surveyor. In addition to that, licensed land surveyors are mandated to attend 15 hours of continuing education annually to ensure that they are kept updated with the new know-hows that would help them on their professional growth.

What does a land surveyor do?

As part of a standard lot or mortgage survey of a property, expect your land surveyor to review tax maps, aerial maps, deeds, subdivision plats, zoning ordinances, subdivision regulations and possibly even flood maps. For a typical lot survey, the subdivision plat is the most important of these because it tells the exact dimensions of your lot and the relative location of your property corners. The surveyor uses this to locate and/or re-establish your property corners.

In the field, a land surveyor will search for your property corners along with some of your neighbors’ corners. If yours can’t be found, they’ll measure the distances and angles between all of the points, locate the improvements on your property, including your house, pool, out-buildings, retaining walls, fences, driveways, sidewalks, and other home improvements. Other improvements like sanitary sewer mains, storm drainage ways, overhead power lines and the like are located because these might indicate an easement across the property. The plat should show these, but may not in all cases.>

Once all of the field information is gathered, the crew chief takes the field notes and prepares a preliminary sketch of the work. This is passed along to a draftsperson who prepares the final outline for your use. The draftsperson will check all of the maps mentioned earlier to make sure that all building setback lines and easements are shown on the draft. The surveyed distances and directions are compared to the plat distances and directions as well. Any discrepancies or encroachments are shown on the drawing. Your lawyer may use the draft to determine if any other legal work is needed during the closing. The mortgage company or the bank may also use the survey for their records.

So now, what do you have for your money. You have a drawing which shows your house on your lot. You should have stakes and/or flagging by all of your property corners. Make sure you know where they are located. The actual corner is marked by an iron pin or pipe of some sort. (The type of monument should be shown in your survey drawing.) You might also want to take a look at them at least once a year to make sure they’re still there. (Even animals mark their territory more often than that.)

Land Surveying in Building your house

It is a very good idea to build your home because you will be able to get exactly what you want instead of when you buy. Of course, you may need to add some things or you may not know what you are getting yourself into.

It is a huge decision choosing the right builder since it is one of the largest personal investments that you will make. Be sure to give an interview to all of the possible contractors and then pick the one that will help make your dream home come true. While you are talking to the possible contractors be sure you ask all of the pertinent questions that will help you choose the best; their how long they have been in the business, experience,  what are the kind of buildings that they have experience building and it would be great if you can see some of their work. It is also crucial to pick house plans which may lead to a good home now and in the future. This is something that your contractor should be able to help you with and they may call on the services of an architect.

Budget in building your house

Before to planning your house design consider these factors; your budget, the size of the home to be built, location of the home, wall finishes, design features that you would like, ceiling height, number of stories, fixture types, exterior finishings, also your time frame.

If you happen to be uncertain about any of these items, your contractor or architect should be able to guide you through this very important process. They will help you choose the details that are right for you down to the very smallest detail. They may refer you to other consultants for things like finishes, colors, and the like so be prepared to sit and discuss with them for a few hours to talk about all these choices that you may have.This is the reason that your choice of a builder is important.

If your builder isn’t able to advise you on home location they should refer you to a real estate agent. A real estate agent is familiar with important details like neighborhood home values, school districts, traffic issues, funding options, etc.

Land Surveying: avoids future problems

Another stop you should make is to see a land surveyor. Land surveyors are trained and experienced in identifying features of the land that might have an impact on your new home – called land surveying. Some of these features are flood zones, property line encroachments from neighbors, lot dimensions, and building setbacks. Land surveyors are measurement experts. And, since your home is your most valuable asset, land surveying should be one of your first steps in any new construction.
