WEST PALM BEACH, Fla. - The 6,400-seat stadium remains an active construction zone as men in bright-colored vests and yellow hard hats work from dawn to dusk to complete the Ballpark of the Palm Beaches before its inaugural game on Feb. 28.

But the elements of their new state-of-the-art spring training facility the Astros need for the next two weeks are functional. Many of the pitchers and catchers due to report Tuesday morning have already checked in to the team's new digs, and Dallas Keuchel and Lance McCullers used the fresh mounds for their bullpen sessions Monday afternoon.

The Astros' side of the complex, which they share with the Washington Nationals, features six practice fields, two for the major leaguers and four for the minor leaguers, and one half-field, to be shared by major and minor leaguers.

A turf agility field separates two sets of 10 mounds and six batting cages, one area for major leaguers and the other for minor leaguers.

The second of the Astros' two major league practice fields is fitted with the exact dimensions of Minute Maid Park, down to the 409-foot distance to straightaway center field after the removal of Tal's Hill. Washington's side of the complex features a practice field with dimensions to match Nationals Park.

An observation tower for the Astros' front-office members is still being constructed. It will stand only steps from the entrance to the minor league side of the building, which consists of two 95-player locker rooms, a coaches locker room, a coaches conference room and a cafeteria.

Connecting the minor league and major league sides of the building is a shared weight room, an area also home to the trainers' room and trainers' offices. A deck of cardio machines overlooks it all.

The major league clubhouse is a short walk away. In the middle of the roughly 6,500-square-foot room, a giant Astros logo looks down from the ceiling. Nameplates for all 59 players in major league camp adorned lockers Monday, with some type of Astros-issued apparel or uniform hanging in most. Ten 70-inch televisions fill the walls.

A video room with space for 20 to 25 seats is just down the hallway. Astros manager A.J. Hinch's office is directly across from a major league coaches conference room, where Hinch, pitching coach Brent Strom and bullpen catcher Javier Bracamonte were busy Monday afternoon planning for a Tuesday meeting.

The coaches and coordinators who work in major league camp have their own locker room. Separate interview and media rooms abut the Astros' lobby, where a staircase leads to the executive offices. (General manager Jeff Luhnow arrived at his office there Monday.)

No major construction remains on the Astros' practice facilities, but minor aspects are still being tweaked as more and more personnel move in.

"You've always got last-minute things that you're going, 'Oh, let's do this. Let's do that. Forgot about this. Forgot about that.' But the core of it's good. It's solid," said Astros senior vice president of business operations Marcel Braithwaite, who led three Houston-based reporters through a 90-minute tour Monday. "The clubhouse is ready. We've pretty much moved in already. All of the trucks have arrived from Houston, and we've got all of the materials that we need in. They're personalizing it.

"Some of the players started showing up early (Monday) and playing catch out on the fields. The fields are pristine. Our focus switches to the stadium to get that across the finish line and be ready for our grand opener."

The Astros insist the stadium will be ready two weeks from Tuesday, when they play visitor to the Nationals, though the work figures to come down to the final day or two. As of Monday, scaffolding still lined the suite level. The concession stands were not yet finished, either.

Upon completion, the Ballpark of the Palm Beaches will hold up to 7,900 fans once standing room and an outfield berm are taken into account.

Because the stadium is shared, each team has a designated dugout - the Astros on the third-base side, the Nationals on the first-base side. A tunnel from the Astros' indoor facilities leads to the left-field area, where the players and coaches will walk to reach their dugout. The Nationals have a tunnel from their side of the complex to their dugout.

There are two visitors locker rooms and separate locker rooms for major league umpires, minor league umpires and female umpires. Even Orbit, the Astros' mascot, has his own room.

While Keuchel and McCullers made use of the weight room and pitchers' mounds Monday, Evan Gattis and Tony Sipp arrived at the complex in street clothes and explored their new spring home. At least three dozen players are expected to report Tuesday, and by Wednesday morning, spring training will be underway with player physicals and the first official workout on the new fields.

"It's nice to see (the complex) come alive," Braithwaite said.
