Projects
Water main replacement, Laurel MD
• |
Scope: Map all utilities within a 10’ corridor of existing water mains. |
• |
Description: PULS crews provided the client with utility mapping at four locations throughout the city of Laurel. At each location, PULS crews located and mapped the specified water main, all services connected to that main, and all utility lines that crossed or paralleled the target main. PULS incorporated this data into the client’s topographic survey for target areas and formatted for AutoCAD. After the client reviewed the utility mapping and determined the corridor for the replacement main at each site, PULS vacuum excavation crews provided the client with exact vertical and horizontal location data at new tie in points and at points of conflict with other utilities. |
Apartment Complex, Fiber Optic Construction
• |
Scope: Locate, mark and designate all private utilities and underground structures on a 5-acre condominium complex, prior to the installation of fiber optic facilities. |
• |
Description: Apartment complex is a 34-year old site with poor utility records and an outdated infrastructure. After two previous firms had been unable to locate a buried PVC gas system with no tracer wire, the client contracted with PULS, Inc. to complete this project. Using the experience of our crews, ground penetrating radar and vacuum excavation PULS, Inc. located the entire gas system. PULS, Inc. provided the client and apartment management company with a detailed and accurate survey of the gas system including the condition of the pipe, soil conditions, location and depth of every service line, tee and main. PULS, Inc. crews worked with the construction crews to ensure quick and safe crossings of all utility lines. |
Site development, Georgia Ave. Washington DC
• |
Scope: Mark all utility lines feeding and surrounding the property, including those in the southbound lanes of Georgia Ave. |
• |
Description: A large metro area land developer, in conjunction with a local engineering firm, requested PULS to mark all utilities for the renovation of an existing building and prior to the installation of new water, sewer and storm pipes for the site. Primary electric, a telephone duct system (with a fiber optic cable), natural gas pipeline, water lines and traffic control cables were designated and documented on a topographic survey and provided to the client for the site. PULS utility research and designation indicated several utility lines and abandoned trolley tracks that were previously unknown to the client. |
I-476 Blue Route Reconstruction Project
• |
Scope: Locate, mark and designate all Penn DOT street lights and ITC fiber optic system facilities along a 7.5 mile reconstruction, paving and guard rail replacement project. |
• |
Description: The client, the general contractor for the I-476 Reconstruction Project, had begun construction on the roadway. During construction, the client became aware that Penn DOT was exempt from existing Pennsylvania One-Call requirements to mark their facilities. Once this was realized, PULS, Inc was brought onsite as an emergency request to locate all the Penn DOT street lighting and fiber optics along the 7.5 miles of the project. PULS, Inc. completed the project quickly allowing the work to continue without further delay. PULS, Inc. provided the client completed surveys showing the location of the designated Penn DOT facilities. |
Towson University, Towson MD
• |
Scope: Designate all utilities on site in preparation for new dormitory construction, installation of new water main, telephone and electric duct system. |
• |
Description: The client and site general contractor needed several utility corridors marked and cleared to avoid damages for structure relocations. PULS crews found and marked a primary electric duct within 2' of a proposed telephone manhole, identified and marked a temporary fiber optic cable and buried communications vault within the proposed path of a new duct bank. PULS provide client with a color-coded sketch of the utilities within each corridor, including detailed notes and descriptions of the utility investigation. |
Project:Hospital Expansion Project
• |
Scope: Designate all underground utilities and provide CCTV inspections, for an $80 million hospital expansion, covering four square city blocks of a hospital property. |
• |
Description: The hospital is a 114-year old complex in the process of completing a major expansion. The general contractor for the project contracted PULS, Inc to locate all buried utility services and structures, including those not shown on records. PULS, Inc. designated all utilities on site, and provided redlined and as-built drawings for the site and recorded CCTV inspections of all storm drains on the property. |
Project: Elementary School, Washington DC
• |
Scope: Designate all underground utilities on the site and the streets that border the property. |
• |
Description: The client engaged PULS to accurately mark and depict all underground utility lines on a topographic survey of the site to supplement an ALTA survey and design for site improvements. PULS crews investigated manholes, vaults, and duct structures, locating previously unidentified fiber optic, secondary electric and gas pipelines. PULS provided the client's survey crew with a color-coded sketch of the utility designation on aerial mapping from the DC GIS. |
Project: Water main replacement, National Guard Training Site.
• |
Scope: Locate, mark and designate all buried facilities over an 8-acre area for a 3,000’+ water main replacement. |
• |
Description: Client contracted PULS, Inc. to locate all utilities and buried facilities that were in the path of a water main replacement. PULS, Inc. located all utilities and facilities in the area and provided the contractor with corrected redlined maps of the area, including previously unknown utilities and buried structures. |
Project: Castle Marina Road, Chester MD
• |
Scope: Mark and verify Miss Utility marks for all underground utilities in path of two Horizontal Directional Drilling bores for the installation of a sewer force main and a vacuum main. Perform test holes on all lines in conflict. |
• |
Description: The client was not comfortable with the location and completeness of the existing marks. They requested PULS to verify and sweep a 1600' and a 1200' corridor for any potential utility conflicts. Two previously unidentified electric lines and storm sewer crossings were located and marked. PULS technicians corrected the markings for the existing force main, which paralleled the proposed bore path. The previous marks were between 3' and 6' off. PULS test hole crews confirmed the actual horizontal and vertical position of the existing force main and other utility conflicts of the proposed bore path with 10 test holes. PULS provided the client with test hole forms for all points of conflict, which included the accurate locations of the force mains, depth of each line and description of the utility systems in conflict. |
