DC Department of Buildings permit SB2600100: issued Jun 18, 2026 for other work at 2128 F St NW. In the Commission of Fine Arts jurisdiction area We propose to drill 2 Standard Penetration Testing borings in accordance with ASTM D-1586 using a trailer-mounted Mobile B-47 HD or a Geoprobe 7822 DT track mounted drill rig. We will be drilling using 3 ? inch ID, 7 5/8 inch OD hollow stem augers to drill the test borings (B-1 and B-2) to depths of approximately 40 feet. We will drill a test well boring (W-1) to a depth of 18 feet using 6 ? in ID, 10 inch OD hollow stem augers. For all 3 borings, the augers will, also, be the outer casing. We will sample every 5 feet driving a 2 inch outside diameter splitspoon sampler. We will drive the sampler in 3 successive 6 inch increments with a 140 pound hammer, free falling a distance of 30 inches. After drilling W-1 is complete, we will install a 4 inch diameter test well in boring W-1. The well will be constructed with 10 feet of 0.020 slot well screen and sufficient solid casing to extend approximately 2.5 to 3 feet above the ground surface. The well top will be secured with a locking friction plug. The annulus around the well will be backfilled with #1 Morie sand to a depth that is approximately 2 feet above the top of the screen. A 2 feet thick bentonite seal (bentonite pellets) will be installed above the sand. The remainder of the annulus will be filled with a bentonite slurry.

Type of work and status are our own standard labels, so permits compare across cities. The city's wording is in the "City's category" and "City's status" rows. We show costs under $100 as not listed, because filers often enter $0 or $1 when the city doesn't require a cost.
