An $8.7 billion Marine Corps base rising at Camp Blaz, an $8 billion missile-defense network approved for 16 sites, a $1.22 billion water programme, a contested $743 million plan to replace Guam's only public hospital, and a $330 million repair of the breakwater that shelters Apra Harbor headline Guam's public pipeline.
*How to read the total: the sum of the published figures in the list below. Bases differ by project — most are total cost estimates, some are federal grants, program totals, or construction contracts as awarded. Each project's expanded view labels its own basis. We add them up with the labels showing rather than pretend they're all the same kind of number.

11 major public projects are listed. The listed figures sum to $20,005,086,417 (≈$20.01B) — and two federal programmes dominate it: the $8.7B Marine Corps Base Camp Blaz build-out and the $8B Guam Defense System (EIAMD) missile-defense network. Bases differ and are labelled on every record: published programme totals, firm contracts, a selected proposer's total, an administration projection and one grant-anchored project value. This is a majors list, not a census: Guam's military construction pipeline, the Guam Transportation Improvement Program and the GovGuam capital budget all carry smaller projects below this page's $10M published-figure threshold. No project is listed as a 2026 completion: the one dated candidate — Andersen's $74.4M Child Development Center, published expected completion July 2026 — has no verifiable opening source, so it stays under construction with that discipline printed on its record, exactly as this series treats 'expected' everywhere.
Owner mapping for a territory: Guam has no state government in the mainland sense and no tribal governments; the Government of Guam and its authorities (Guam Power Authority, Guam Waterworks Authority, Port Authority of Guam, Guam Memorial Hospital Authority, Guam Department of Education, Department of Public Works) are this page's state-equivalent public owner and are listed at level 'state', while Department of Defense owners (NAVFAC, Joint Region Marianas, the Missile Defense Agency, the services) are listed at level 'federal'. Private owners are excluded under the series rule, however large: named, not listed, are Korea Electric Power's Guam Ukudu Power plant (below, as a completion), Guam Regional Medical City (the island's private hospital), Docomo Pacific / GTA / IT&E telecom builds, hotel and resort construction, and the private share of any public-private housing or energy ventures.
Federal buildup discipline: Guam is mid-way through the largest military construction effort in its history, and this page counts it once. The Camp Blaz relocation is listed as ONE programme-total record ($8.7B): its individual awards — the $61.9M training center, the $112.6M 9th Engineer Support Battalion facilities, the $78.4M corrosion repair facility, the $44.3M education center, the $16M headquarters phase and others — are disclosed inside that record, never added to it. The missile-defense network is likewise ONE programme-total record ($8B), with its one priced construction element (the $295M Guam Defense System Command Center, contracted July 2025) and its Aegis development contract disclosed inside it. Andersen and Naval Base projects that are not elements of either programme — family housing, the HSC-25 hangar, the child development center, the Glass Breakwater — are listed separately at their own contract figures.
Completed in a prior year, however large — excluded and named: the Ukudu Power Plant (198 MW combined cycle, about $600M investment, Guam Power Authority with Guam Ukudu Power) — GPA announced its commissioning on December 25, 2025 and it was fully online on Christmas Day 2025, a 2025 completion, so it is named here and not listed, with GPA's own figure; Camp Blaz's activation milestones and phased facility openings of 2020–2024, including the Mason Live Fire Training Range Complex and Skaggs Urban Combat Training Complex delivered in that period; GWA's Northern District Wastewater Treatment Plant upgrade ($122M, secondary treatment, completed before 2026); the University of Guam's Student Success Center (about $22.9M) and its $7.9M School of Engineering Building (the latter also below the floor), both completed before 2026; and the Dededo sports complex works of earlier years. Unpriced or unfunded planning, named not listed: the Port Authority's further priority list (F2–F6 wharf rehabilitation, Golf Pier and F1 Pier replacement) without verified individual figures; a joint consolidated communications center at Andersen that NAVFAC projected in the $250–500M range before award; and Andersen's planned duplex housing expansion beyond Phases IX–X.
News-flagged records: four records rest on Guam news reporting of official figures — the new hospital's $743M administration projection (Pacific Daily News), the Defense Access Road programme total (Marianas Business Journal, from DPW's published transportation plan), the Simon Sanchez proposal total (Marianas Business Journal, from DPW's released procurement record) and the EIAMD programme figure (Arms Control Association, reporting MDA's announcement and final EIS). Each is flagged on its record. Guam's procurement and programme documents are frequently published through its newspapers rather than posted in full by agencies; where an official source existed (NAVFAC, DVIDS, the Port, GWA's bond statement) it is the source printed.
