Apologies, but I feel like you're misunderstanding my comments.

343 Madison's foundation progress is currently where 70 HY's foundation was at 6-7 months ago. I understand that 70 HY started later, that's not what I'm arguing. 343 started earlier (yes i also know that) but on Phase 1, not the tower. Excavation of Phase 2 for 343 Madison didn't start until this was well under construction and excavation.

It doesn't matter that 70 HY is going up faster, it's going up "faster" because it started earlier relative to when the tower phase at 343 actually started, not Phase 1 construction.

Related’s 70 Hudson Yards is coming online at the right time

With little new office construction on the horizon and tenants racing to secure trophy space, Related Companies’ latest Hudson Yards tower appears to be arriving at just the right moment.

After landing Deloitte as an anchor tenant for 900,000 square feet at its under-construction 70 Hudson Yards tower, Related Companies is negotiating deals for roughly half of the remaining space, company representatives said. The 1.1-million-square-foot project is now a few months ahead of schedule, with Related expecting a temporary certificate of occupancy as early as summer 2028.

Construction began a year ago, just as Manhattan’s office market started to show signs of a sustained rebound. Leasing activity has continued to accelerate, fueled by demand for high-quality, well-located space. Hudson Yards’ availability rate fell to just 4.5 percent in this year’s second quarter, according to Colliers, leaving companies with expiring leases or plans to expand scrambling to secure space within the neighborhood.

“There’s a strong desire to be here and to grow within the campus,” Related’s Stephen Winter said. “It just felt like a no-brainer to introduce another office tower to Hudson Yards.”

The tower is the first of only a handful of new Manhattan office developments slated for delivery over the next several years. With Hudson Yards effectively full and Park Avenue vacancy for Class A and B buildings hovering at record lows, brokers say companies seeking large blocks in trophy towers have few options. Tenants have already leased 80 percent of the office space currently under construction in Manhattan, according to JLL.

The scarcity of new development has pushed companies to plan far ahead, with tenants signing leases years before projects are completed. Law firm Simpson Thacher & Bartlett inked a 916,000-square-foot lease at Extell Development’s 570 Fifth Avenue tower, which is slated for completion a few months after Related’s project. Meanwhile, insurance giant Starr and law firm McDermott Will & Schulte have already committed to major leases at BXP’s 343 Madison Avenue, another ground-up office project expected to deliver in 2029.

”If you want that type of top quality space, you need to make two-, three-, four-, five-year in advance commitments,” JLL broker Benjamin Bass said. “Otherwise, that space will be leased [by another tenant].”

That was the case when Deloitte signed an 807,000-square-foot lease at 70 Hudson Yards earlier this year, then later expanded its commitment by roughly 93,000 square feet in a deal valued at about $3 billion. Bass, who was part of the landlord’s leasing team, said Deloitte was looking to consolidate its offices and lock in enough space to grow its business.

You still seem to completely miss the point. So I’ll leave it at thst. Just know that 70 Hudson is well ahead of 343 Madison.

TKD is professionally involved in the development of 343 Madison and I'm sure he completely understands your point. The fact that 343 is slower to get out of the ground is not revelatory in the slightest. His explanation makes whatever point you're trying to make basically useless.
