Several steps away from the crumbling edge of East 26th Street in Charles Village, a construction worker slowly unrolled a long yellow measuring tape into a circular hole about the size of a sewer manhole lid.
Foot after foot of the tape disappeared as he sought to learn the depth of the hole being bored straight down into the earth by a hulking orange drilling machine anchored not far from St. Paul Street.
Another worker at the block-long construction site Tuesday said the hole is the first of many that will be cut into the street as part of a new design to keep East 26th Street and the earth beneath it from spilling down onto the railroad tracks, which run parallel to the street, as they did last week when a century-old retaining wall collapsed amid heavy rain.
Adrienne Barnes, a city Transportation Department spokeswoman, said the city hired contractors to replace the retaining wall and repair the street. She said that 65 "borings" or "piles" are being inserted into the street by contractors hired by the city.
Such holes can be filled with steel beams or underground caissons to bolster ground stability and anchor retaining walls, experts said.
Barnes said the contract for the work is not finalized and there is no estimate of the cost or other specifics about the project.
"This is an emergency. It wasn't anything we planned for or anything that was projected. It was something we had to do," Barnes said. "We don't have any final numbers yet. Our job is to restore the neighborhood. We need to do whatever we need to do."
Jack Temple, who lives at the corner of East 26th and St. Paul, said residents were told at an informational meeting Sunday that "barring setbacks," the project could take as little as three weeks, far shorter than the 40 days they were told they might be displaced from their homes. In the meantime, Temple who said he "absolutely" appreciates the quick start to repairs is staying in a Towson hotel room provided by the city.
The city is proceeding with the work despite questions about who may be responsible for the accident, which sent the masonry wall, tons of earth and asphalt as well as eight cars tumbling onto the railroad tracks below. The city and CSX Transportation, which owns the tracks, have tussled in the past about who is responsible for maintaining the walls.
Bryan Rhode, CSX's regional vice president for state government affairs, said in a statement that the city is "leading the efforts in stabilizing the site, supporting the needs of residents and developing plans for reconstruction," and that the railroad is "grateful and supportive of the city's actions in focusing on those immediate requirements."

Norfolk Southern Railway has begun building a retaining wall along its tracks beneath the Mount Washington hillside that gave way last month, burying the rail line.
Spokesman David Pidgeon said the wall will be 320 feet long and take about three weeks to complete. Crews were on the site, adjacent to the Duquesne Incline, erecting piles and moving earth this week.
A section of hillside the length of a football field tore loose on April 8, sending a massive amount of mud and trees across the tracks, which run parallel to West Carson Street.
No one was injured. Freight traffic was interrupted for several hours while Norfolk Southern and city crews cleared the tracks.
Heavy rain that preceded the slide may have saturated the soil and weakened the hillside, an engineer for the city said.
Mr. Pidgeon said the railroad would not comment about the cost of the damage and the retaining wall or whether it would seek reimbursement from the city, which owns the hillside.
A spokesman for the city's Bureau of Building Inspection said the agency is continuing to work with property owners of structures located on Grandview Avenue above the slide. None of the engineering reports submitted on behalf of those buildings has indicated there are any structural issues.

Work starts on wall to protect Pittsburgh rail line

One week after the collapse of a large retaining wall between CSX Transportation railroad tracks and East 26th Street in Charles Village, city officials said they still had not determined who was responsible for the wall or who will pay the cost to repair it.
Officials said they are still poring over decades of documents, including a 1998 agreement between the city and CSX showing that, at least once in the past, they cooperated to repair retaining walls in the neighborhood.
Responsibility for last week's wall failure, which dumped half the block and eight cars onto the railroad tracks below and forced residents of 19 homes to evacuate the area, has been a key question. Repair costs could top $1 million, and residents said they had raised concerns about cracks and sinking asphalt along the street for years.
The 1998 agreement, released in response to a request from The Baltimore Sun, shows the city and the railroad split an estimated $880,000 bill for repairs to a stretch of retention walls just a couple of blocks from last week's collapse and along the same string of railroad cuts that runs parallel to East 26th Street.
CSX and city property lines intersect across the city.
The company could not be reached to comment Wednesday.
Mayor Stephanie Rawlings-Blake and Transportation Director William Johnson said at a news conference at the site Wednesday that many questions, including who should maintain the wall, remained unanswered. The mayor said she was focused on helping displaced residents, and that she directed city agencies to work quickly to find answers.
Johnson said new ground-penetrating radar testing of St. Paul and North Charles streets, which run past and perpendicular to East 26th, showed no major structural concerns, and that survey crews continue to monitor any movement on East 26th.
Radar testing would not be conclusive on East 26th, he said, because the radar waves interacting with the uneven, exposed-dirt slope of the street would yield unclear images.

tilt

While most observation decks elicit responses ranging from ahh to ooh, visitors to Chicagos John Hancock Center may be more inclined to opt for something like, Whoa!
On Saturday, the buildings 94th-floor observation deck will unveil TILT, a glass-lined, 8-person enclosure that will pivot out from the building faade and provide views that stretch from the city skyline to Michigan Avenue, almost 1,000 feet below.
As such, it promises to provide a whole new slant on the observation deck experience.
Traditionally, visiting an observation deck has been a fairly passive experience where you go up to a floor, stand at the windows and take in the view, said Nichole Williamson, general manager of 360 Chicago, which owns and operates the observation deck. The idea came to us to introduce a sense of movement into the experience.
That experience entails standing in a bank of bays as the enclosure pivots outward and tilts downward 30 degrees for about 30 seconds.
You definitely get the sense that something unusual is happening as you start to tilt out, said Williamson. You can see directly down the face of the building, which is a view you dont normally get to see.
Having done it dozens of times herself usually in 4-inch heels she says the experience is designed to be thrilling rather than terrifying.
