Surveying Services for The Construction Industry

M. Lacey Land Surveying offers a wide variety of services for the construction industry. We can perform all your layout needs, such
as roadways, bridges, curb lines, utilities, building pads, towers, etc. We will take the extra effort required to assure that potential
problems are caught before becoming issues. We are a small company, fully insured, qualified, and pride ourselves in being an ethical
and professional team player. This provides our clients with the quality and expertise required to help bring the project to a successful
completion.

Some of our services include:

Horizontal and Vertical Control Networks

Control surveys are conducted to establish points in the field on the same horizontal and vertical control network as the site plan or
construction plan. These networks are generally established for the contractor to use to set up their 3D surface modeling and machine
control system. Control points will be set in the field at locations outside of the area of disturbance that are accessible and opened for
GPS receivers.

Centerline Roadway & Curb Layout

Roadway centerline and curb stakes are generally set on 50-ft stations for straight runs, 25-ft stations for both horizontal and vertical
curves, and at the beginning, end, high and low points of all curves. Elevations are set on the stakes and a grade sheet and sketch is
provided showing the cut/fill from the stake.

Infrastructure Layout

An offset stake and an alignment stake is set at each structure location, including catch basins, manholes, hydrants, vaults, etc.
Elevations are set on the stakes, and a grade sheet and a sketch is provided showing the cut/fill from the stake to a feature on the
structure such as rim, and invert.

Verification Survey

Prior to starting the project, we can perform field checks to verify the topographic survey used for the design. It is better to know at the
start of a project, if the data used for earthwork calculations is correct, rather than at the end of the project.

Quantity Surveys

Quantity Surveys or Volume Surveys are for determining the amount of earth movement conducted over a period of time. This is
usually completed on sites requiring large amounts of earthwork to determine payment to contractors, land owners, and government
agencies.

Building Layout

Offset stakes are set opposite the main foundation corners. The stakes are generally set opposite each other so a line can be ran
between the stakes creating a box, leaving room for the excavator. A benchmark is set for vertical reference, and a sketch is provided
showing the location of the stakes in relation to the building foundation.

Building Control Surveys

Building control surveys include the layout of the building column lines for the construction of the building foundation, and placement
of the anchor bolts. For building additions, the theoretical column lines are tied into the existing columns and verified against additional
features on the existing structure such as exterior walls.

Anchor Bolt Surveys

After the placement of anchor bolts by the contractor, a survey is completed to verify the location of the anchor bolts. A plan, sketch,
or spreadsheet is prepared showing the as-built location of the anchor bolts in relation to the column line grid. This information is used
by the structural engineer, and fabricators to determine what adjustments need to be made to the steel columns and girders.

Structural Deformation Monitoring

These services include precise monitoring of structures for lateral and/or vertical movement, structural deformation monitoring for
bridges and buildings, and subsidence monitoring for earthwork embankment projects such as earthen dams. These surveys include
an analysis of correct survey procedures and the determination of control geometry.

Boundary Survey

M. Lacey Land Surveying is licensed to perform boundary surveys in Tennessee & Virginia. We can provide you with property
corners markers and stakes along the property line, helping to ensure that construction activities stay within the site.

As-built Surveys

As-built surveys are generally done at the completion of construction to show that all of the improvements constructed conform to the
site plan, and are within the property boundaries. As-built surveys show an accurate representation of post construction conditions for
all types of sites, such as shopping centers, schools, residential subdivisions, and new infrastructure. These surveys are generally
required by the municipalities and/or lending institutions.

3D Surface Modeling

3D machine control technology has changed the world of construction. At the center of this technology is the 3D surface model.
Working with an accurate model will increase productivity, which leads to less labor, less fuel, less machine maintenance, and
ultimately, more profit.

M. Lacey Land Surveying can provide you with an accurate 3D surface model created using both the engineered digital plans and
paper copies. The 3D model will represent all the sections, profiles, and details provided in the plans. The road surfaces are modeled
using horizontal and vertical alignments to accurately produce true transitions in slopes and super-elevations making them smooth and
accurate.

After the 3D model is complete, we will review it and note any areas of concern. This gives the designers a chance to fix problems
before the project starts, saving everyone involved, time, and money.
