LFA Presents at ISPLS Annual Conference

At the most recent annual conference sponsored by the Indiana Society of Professional Land Surveyors, Shane Turay and Aaron Blank made a presentation to roughly 100 fellow surveyors about the merits of being a professional topographer and civil engineering surveyor.

The course objective was to encourage surveyors to think about producing surveying products that are as professionally executed as boundary surveys. The presentation focused on the techniques and tools used by those involved in the field of topographic and civil engineering surveys. The goal of the presentation was to encourage high quality, professional work, and to share lessons and experiences with one another.

ISPLS Annual Conference

The presentation lasted 50 minutes, and with Shane’s flair for effective story-telling, the objectives of the seminar were met. Several attendees sought Shane and Aaron after the presentation to inquire about the practices employed at LFA to ensure that we consistently deliver a high quality product that not only fulfills the requested scope requirements, but also ensures that the receiver of the survey information has the highest level of confidence proceeding with the elements of their design.

It was a positive experience that Shane and Aaron both hope to repeat in the future.

LFA Engineering Design – Ireland Road/Locust Road Intersection

Did you know LFA designed the signalization and grade improvements at the Ireland Road/Locust Road intersection?

Sight distance deficiencies in addition to the location of two single family homes immediately north of the intersection required attention. Meeting the homeowners needs, focus was placed on the relocation and reconfiguration of the existing drives to allow garage usage.

Concrete modular block retaining walls were built to overcome the proposed elevation difference fulfilling the project’s needs.

This project also included coordination with two ARRA INDOT bridge replacements immediately north and east of its limits.

LFA was solely responsible for roadway design, drainage design, pavement markings and signing, lighting, signalization, right-of-way engineering, maintenance of traffic, and construction inspection.

IndianaMAP

Geographic Information Systems (GIS) technology is utilized by Lawson-Fisher Associates on a daily basis as part of our civil engineering operation. While the majority of our GIS operation involves analyzing/manipulating spatial and geographical data, there are instances when it is desirable to quickly view and query available GIS data. IndianaMAP is one such available tool that allows a user online access to a publicly available collection of GIS layers.

The IndianaMAP Layer Gallery (http://maps.indiana.edu/LayerGallery.html) allows users to select up to 260 layers of GIS data. The available data includes layers related to Demographics (census, population, etc.), Environment (soils, storage tanks, ecology, etc.), Geology (petroleum wells, earthquake epicenters, etc.), Government (civil township boundaries, voting districts, etc.), Hydrology (floodplains, wetlands, watersheds, etc.), Imagery (aerial photography, topography, etc.), Infrastructure (dams, railroads, schools, etc.), and Reference Layers (USGS contours, zip codes, etc.).

IndianaMAP layers

Once the desired layers are selected, the IndianaMAP Viewer (http://maps.indiana.edu/index.html) is utilized to view and query the desired attributes within the selected layer

IndianaMAP is a user-friendly tool that can be utilized for a variety of planning and assessment purposes.

MS4 Compliance with GIS

Storm Sewers collect surface runoff and often discharge these flows directly to our local waterbodies without treatment. Pollutants such as grease, oil, dirt, chemicals, etc. picked up during runoff enter the storm sewer system causing water quality issues. The MS4 Compliance program is designed to minimize the discharge of these pollutants into the storm sewer system.

Lawson-Fisher Associates has been working with the City of Mishawaka to provide documentation and mapping of their storm water infrastructure using GIS to comply with EPA’s MS4 program.

LFA GPS’d the location of all outfalls within the City and loaded them into the City’s sde database for mapping. This information along with as-built construction drawings of the storm sewer system was used to create the additional features of the infrastructure in the City’s GIS. LFA also provided the City with a manual of all the receiving streams and the appropriate outfalls and documentation within each receiving stream that is attached to the outfall feature in the GIS. A SOP (Standard Operating Procedure) was also provided for future outfalls the City may encounter on their own. LFA continues to update and manage the GIS mapping for the City’s compliance.

Trenchless Technology – Sanitary Lateral Rehabilitation

Trenchless Technology for both new construction and rehabilitation of existing infrastructure is a constantly growing and improving field. Over the past several years, LFA has had the opportunity to both design and inspect several projects utilizing trenchless technology, including Sliplining repair, Horizontal Directional Drilling (HDD) of sewer force mains, Bore & Jack pipeline/casing installation, Polyurethane coating rehabilitation of both main line pipe and structures and Cured-in-Place Pipe Lining (CIPP) for both main line and lateral lining rehabilitation.

Mishawaka CIPPSanitary lateral rehabilitation is one of the areas of trenchless technology that LFA has experience.  Lateral rehabilitation for municipalities is a complex topic. Often laterals are the responsibility of the homeowner and therefore municipalities refrain from addressing this portion of the overall system. However, municipalities have a vested interest in the condition of the laterals. Sanitary laterals in poor condition may contribute a significant component of infiltration and inflow to the sewer system – which in turn impacts available capacity and can result in combined sewer overflows and/or dry weather overflows. This component will remain (and may increase) following rehabilitation of the main line or trunk sewers. Additionally, failing laterals within the right of way may adversely impact other existing infrastructure (i.e.  other utilities, pavement).  Emergency repairs, which may be the responsibility of the homeowner, will potentially impact other city services, impact traffic flow, etc. Another consideration is if the municipality offers or mandates lateral insurance, the expense of repairs may […]
