The National Park Service (NPS) Denver Service Center (DSC) has issued Solicitation No. 140P2026R0007 for the "Replace Main Distribution – CAVE 332397" project, dated November 6, 2025. This contract aims to replace the aged water distribution system in the historic area of Carlsbad Caverns National Park, New Mexico, originally installed between 1932-1964. The project is critical for protecting the primary park resource (the Caverns), ensuring a sustainable water supply for approximately 70 employees and 350,000 annual visitors, and modernizing the 70-year-old failing water line infrastructure, including fire hydrants that do not meet NFPA Fire code. The contract is a Firm-Fixed-Price (FFP) offer with base and optional line items, including borings, trenching, demolition, piping, and landscape repair. Key personnel, electronic invoicing via the IPP System, and a prohibition on ATVs are outlined. The contractor must commence work within 10 calendar days of notice to proceed and complete it within 390 calendar days, with liquidated damages of $1,498 per day for delays.
The document outlines a project to modernize the sewer system and watermain at Carlsbad Caverns National Park in Eddy County, New Mexico. The project, titled "MODERNIZE SEWER SYSTEM, BAT FLIGHT DRAW HOUSING AND ADMIN AREA LIFT STATION, AND 8" WATERMAIN," involves significant ground-disturbing activities. Key general notes emphasize the contractor's responsibility for accurately locating and protecting existing utilities, verifying site conditions, and protecting existing infrastructure, buildings, trees, and landscaping. The project requires archaeological monitoring, a Storm Water Pollution Prevention Plan (SWPPP), prevention of non-native plant introduction, and proper disposal of debris and removed vegetation. Due to the presence of karst features, geophysical surveys and soil borings are mandated to assess void risks. Revegetation efforts are planned in sections due to the project's extended timeline. The document also provides a detailed sheet index for the construction drawings and defines existing and proposed symbols and abbreviations.

This government file details a project to modernize the sewer system, replace the Bat Flight Draw (BFD) Lift Station, and upgrade an 8-inch watermain at Carlsbad Caverns National Park in New Mexico. The project is divided into three main components, each with specific work requirements, including replacing gravity sewer lines, demolishing and constructing a new lift station with controls, and replacing an 8-inch watermain. The work involves extensive excavation, rock trenching, demolition, installation of new piping and manholes, and significant hardscape and landscape repair, including revegetation. Strict environmental and operational restrictions are in place, such as prohibitions on blasting and directional drilling, limitations on work hours, noise levels to protect bats, and requirements for archaeological and historical preservation. The project emphasizes detailed coordination, submittals, and adherence to specific pricing requirements for contract modifications, ensuring all work is performed under a single prime contract with a 658-calendar day completion limit.
This government file outlines the "Replace Aged and Failing Water System in Historic District" project at Carlsbad Caverns National Park in New Mexico. The project, managed by the National Park Service, involves replacing the existing water distribution system within the housing and administration area. Key aspects include field verifying existing utility locations, installing new water mains with a minimum 30-inch cover, and ensuring a minimum 12-inch vertical separation between water and dry utilities. The contractor is responsible for archaeological monitoring, storm water pollution prevention, and protecting historical features. Geological surveys highlight potential karst features, requiring exploratory borings. Staging areas are designated at a gravel pit, historic tennis courts, and the Visitor Center West Parking Lot. The project emphasizes environmental protection, historical preservation, and meticulous planning for utility replacement and site restoration.
The Carlsbad Caverns National Park seeks to replace its aged and failing water system in the Administration and Housing Area, Carlsbad, New Mexico. This project, identified as PMIS NO. 332397, involves the National Park Service and the Intermountain Regional Office-Facility Management. Construction documents, including the project manual, were prepared in March 2025. The initiative aims to modernize essential infrastructure to ensure reliable water supply and system functionality within the park's administrative and residential zones, highlighting a critical upgrade to support park operations and resident well-being.
HDR Engineering, Inc. conducted an electrical resistivity (ER) and ground penetrating radar (GPR) survey at Carlsbad Caverns National Park to identify subsurface voids and existing utilities along a proposed electrical duct bank alignment. The project, located in Eddy County, NM, aimed to detect shallow voids in limestone within 15 to 50 feet of the surface and map utilities like electrical, telecom, fiber optic, water, and sewer lines. Fieldwork, performed from May 12-21, 2020, utilized ER tomography for void detection in areas without utility interference and GPR in utility-rich or paved areas for void and utility identification. The RD8000 Locator and Global Positioning System (GPS) were used for utility tracing and accurate spatial data collection. The survey identified several high-amplitude resistivity anomalies and GPR signatures consistent with potential voids, along with mapping various utilities to inform the electrical system design and construction. The report includes detailed data results, figures, and coordinates of interpreted anomalies.
Collier Geophysics was contracted by the U.S. National Park Service to conduct geophysical surveys at Carlsbad Caverns National Park to assess and map the risk of subsurface voids and karst features across six areas totaling approximately 35 acres. The primary goal was to support facilities management planning for future below-grade utility work. Three geophysical methods were deployed: Ground Penetrating Radar (GPR) for shallow karst potential in paved areas, Frequency Domain Electromagnetics (FDEM) as a supplementary method for unpaved areas, and Electrical Resistivity Tomography (ERT) for deeper karst potential. The survey identified high and moderate risk zones, particularly in Areas 1-4 and 6. Areas with dense infrastructure or large amounts of dense carbonate rock posed challenges, reducing data quality and confidence in results. The report details the methods, processing workflows, and interpretations, noting that geophysical anomalies indicative of karst features were identified and integrated into combined risk assessment maps.
Collier Geophysics was contracted by the National Park Service (Contract: 140P1322P0045P) to conduct a geophysical investigation across six areas at Carlsbad Caverns National Park, New Mexico. The primary goal was to assess and map the risk of voids and karst features in the shallow subsurface to support future utility improvements and excavations. The study utilized Ground-Penetrating Radar (GPR) for shallow karst potential in paved areas, Frequency-Domain Electromagnetic (FDEM) as a supplementary method for unpaved areas, and Electrical Resistivity Tomography (ERT) for deeper karst potential. The results identified high and moderate risk zones based on geophysical anomalies indicative of karst, with GPR being the most precise method. Areas 1-4 and 6 showed several high and moderate risk zones, while Area 5, characterized by dense carbonate rock, presented data acquisition challenges but still yielded risk interpretations based on geophysical trends and geological observations. The report emphasizes consulting detailed anomaly maps alongside simplified risk maps due to inherent limitations in remote sensing interpretations and data quality variations, especially in areas with dense infrastructure.
The provided document is a Hydrant Test Report form, designed for recording critical data from fire hydrant performance tests. It includes fields for date, time, nozzle size, coefficient, pressure, flow rates (total and at 20 psi), test duration, water used, static pressure, residual pressure, and pitot pressure. The report emphasizes adherence to the American Water Works Association Manual of Water Supply Practices M17 for testing procedures and must be used with a hydrant location map. Accompanying the report is a fire hydrant map for the Carlsbad Caverns Admin and Staff Housing, detailing the locations of five fire hydrants (FH#1 to FH#5), water mains (8" and 4"), and a water storage tank, crucial for emergency response planning and infrastructure maintenance.
