Construction Done Right

LSN is committed to completing your project
on time and on budget while providing:



LSN prides itself on paying attention to the small details that put the finishing touches on a completed project.

  • Materials

    From the early stages of each project, LSN ensures that quality materials are submitted, reviewed and approved by the appropriate party prior to any work being initiated. This quality is maintained by our foremen and field personnel to make sure the end result is as intended.

  • Craftsmanship

    Our skilled work force is certified in each respective trade and makes continuous efforts to remain up to date on their skill sets.

  • Commitment

    LSN, and it's officers, are committed to getting each project done correctly and in a timely fashion. We value our client's time and make all efforts to streamline the construction process from design to completion.

  • Award Winning

    LSN has been awarded the Historical Excellence Award for the work completed on the Arch Street DayCare Facility. The space was part of the Presbyterian Church located at 18th & Arch Streets in Philadelphia that had not been used in over 90 years. LSN converted the space into a daycare facility that benefits many Center City employees searching for that service.

  • Recognized

    LSN was also interviewed for an article published in the Construction Today Magazine for the new construction of the Regional Presbytery Headquarters Building. This 9,000 sq ft new construction facility is the main office for all 137 Presbyterian Churches within the Region. To read the full article, click here.

Our first priority for each project is to identify the specific tasks for the work involved and the associated hazards for those tasks.  Once that is established, we perform an analysis to mitigate those hazards.

  • Planning

    LSN has a comprehensive safety plan that evolves as the company and technology evolve. We also tailor our safety plan to make it site specific for many projects.

  • Innovation

    Our goal is to streamline the construction process and eliminate response lead times by handling shop drawings, RFIs and other construction related tasks electronically. This results in shorter project schedules and happier clients.

  • Training

    One of the keys to our success is the ongoing personnel training for field and office personnel to ensure that we are in compliance with all current OSHA standards. Field personnel are required to participate in weekly tool box talks to discuss topics including, but not limited to: Fall Protection, Personal Protective Equipment, Proper Lifting Techniques, Tool Use & Maintenance.

    All foremen and project managers are OSHA-30 certified and all laborers are OSHA-10 certified at a minimum.

  • Communication

    Our project managers work very closely with field personnel to ensure materials are on site in a timely fashion, the correct manpower is being utilized for each task, the proper tools are on site, equipment and material approvals are submitted on time to allow the project schedule to run smoothly.

  • Experience
