BILD Alberta formally wrote to the Government of Alberta to pause adoption of the 2025 National Building Code (NBC). Here's our concern: the 2025 NBC has drifted well beyond its core purpose of health and safety, adding between $17,000 and $39,000 in new costs to a typical single-family home. If Alberta were to progress to the highest energy tier (Tier 5), that figure climbs past $128,000. These changes bring real complexity, constructability challenges, and interpretive uncertainty — without clear, commensurate benefit. Many aren't driven by consumer demand, and the analysis meant to justify them is often absent or incomplete. The responsible path is to pause: give industry, government, and building officials the time to properly review, test, and evaluate these proposals against the benefit they actually deliver to Albertans. BILD Alberta strongly supports a harmonized national building code. That's exactly why we're raising the alarm. We're also calling on the federal government to reform the priorities and processes behind our national code system. Read our full submission here: bildalberta.ca/wp-content/up…

Interconnection isn't just an electrical challenge. Permitting, drainage, fire access, and constructability issues can delay projects long after a queue position is secured. KWRE aligns electrical, civil, hydrology, and permitting experts early to help keep projects on track.

The cheapest problems in construction are solved before anyone picks up a tool. That is why the early conversations matter so much. Scope reviews, pricing checks, schedule planning, and constructability input can feel like extra steps, but those steps are where risk gets reduced.

Why does this matter in the real world? Constructability and liability. Wall-mounted folding seats require massive structural backing inside the wall cavity and precise waterproofing detailing around the fasteners. In the field, these are notorious failure points. Field-added seats frequently fail the 250-lb deflection and load testing during final inspections, triggering costly rework and delayed occupancy certificates.

LuminaNitinol: A Light-Responsive Hybrid Polymer Aerogel System for Modular Ground-to-LEO Infrastructure White Paper – Version 3.0 June 2026 Abstract LuminaNitinol is a conceptual multi-functional material system developed for extreme structural applications. It consists of a multi-layered hybrid architecture combining a polymer aerogel matrix with carbon fiber reinforced polymer (CFRP) layers and embedded three-dimensional nanites. These nanites respond to specific light signals to enable localized self-assembly and information transfer but are not self-propagating. The material is manufactured through a light-driven photochemical process. Upper sections incorporate a recycled tire-derived rubber composite for radiation shielding, while the inner surface of the structure is coated with the same composite to serve as the guideway for a magnetic levitation system. The primary application is a modular, ground-based elevator reaching Low Earth Orbit. The structure uses Curved Trapezoidal Ring Segments as its official modular block shape, maintains a 7° tilt counter to Earth’s rotation, and extends foundations into the asthenosphere. Magnetic connections at segment interfaces support modular assembly. 1. Introduction Building structures capable of reaching Low Earth Orbit from the ground requires materials that combine very low density, high specific strength, impact resistance, radiation tolerance, and modular constructability. LuminaNitinol integrates these capabilities through a hybrid layered architecture and active nanoscale functionality under optical control. 2. Material Concept and Evolution LuminaNitinol evolved from earlier concepts (Dilataero and DilataNitinol) into its current form through the addition of embedded nanites and light-mediated control. The current architecture includes: Dilataero layers containing densely packed three-dimensional nanites distributed from the center of each modular block. These nanites respond to specific light signals to enable localized self-assembly and information transfer but are not self-propagating. CFRP layers that provide compressive strength and stiffness. Radiation-shielding layers produced from devulcanized recycled tire rubber compounded with hydrogen-rich additives and boron or iron-based fillers, applied to upper sections. Maglev interface coating using the same recycled tire-rubber composite as a durable inner lining for the magnetic levitation guideway. 3. Manufacturing Methodology LuminaNitinol is produced via a light-driven photochemical process beginning with simple molecular precursors. Key elements include: Staged exposure using UVA (340–400 nm) for polymerization initiation, green light centered at 532 nm under TM polarization and ~45° incidence to enhance interfacial effects, and near-infrared (900–1100 nm) for controlled drying. Fibonacci-sequence light patterning combined with internal reflective surfaces to promote efficient hierarchical structure formation. Integration of light-responsive nanites that support localized self-assembly and information transfer throughout each block volume. These nanites are not self-propagating. Small amounts of sugar incorporated during early gelation to improve pore uniformity through hydrogen bonding. The recycled tire-rubber radiation-shielding composite is produced separately through mechanical devulcanization and compounding before being applied as outer shielding layers or as an inner coating for the maglev system. 4. Structural Design The elevator is configured as a multi-layered circular tower with a 7° tilt counter to Earth’s rotation. Lower sections extend into the asthenosphere to improve torsional stability. Official Modular Block Shape: Curved Trapezoidal Ring Segments Each block is a curved trapezoidal ring segment designed so that multiple segments assemble side-by-side to form complete circular rings. The trapezoidal profile accommodates the 7° tilt while maintaining structural efficiency. Segments are manufactured as multi-layered units and include magnetic connection zones along their interfaces. 5. Cost Considerations (Baseline) Using the finalized baseline parameters: Density: 0.005 g/cm³ Medium material cost: $2,500 per kg Each Curved Trapezoidal Ring Segment has an estimated volume of approximately 28 m³, resulting in a mass of 140 kg. Theoretical material cost per block: $350,000 at $2,500/kg Cost range: $210,000 – $560,000 per segment This represents raw material cost only. Actual manufacturing costs during early development are expected to be significantly higher due to the complexity of the light-driven process and nanite integration. 6. Construction and Assembly Large Curved Trapezoidal Ring Segments are manufactured on the ground using the light-driven process. These segments are assembled progressively using magnetic connections at the interfaces. The magnetic systems enable self-alignment during placement and can be supplemented by mechanical locking. The modular design supports staged construction from the surface upward, with lower sections eventually reaching asthenospheric depths and upper sections receiving radiation-shielding layers. 7. Target Application: Ground-to-LEO Elevator The primary application is a ground-based elevator system reaching Low Earth Orbit. The multi-layered circular tower provides structural support, radiation protection in upper sections, and a durable guideway for the magnetically levitated climber. The non-Newtonian behavior and light-responsive nanites contribute to impact resistance and potential localized adaptation during operation. 8. Research and Development Roadmap Phase 1: Fundamental Research & Molecular Design (Year 1–2) Design segmented polymers with photo-responsive groups and dynamic bonds. Develop light-responsive nanites capable of responding to specific wavelengths and polarization states. Model light propagation, Fibonacci patterning, internal reflective surfaces, and nanite-light interactions. Establish baseline optical parameters (UVA, 532 nm green light with TM polarization, near-IR). Simulate 3D nanite distribution and information transfer via light signals. Phase 2: Lab-Scale Synthesis & Proof of Concept (Year 2–4) Synthesize base monomers and integrate nanites into small-scale samples. Develop and test staged light exposure protocols (UVA → Green → Near-IR). Validate Fibonacci light patterning and internal reflective surface formation. Test small amounts of sugar as a structure-directing agent. Characterize mechanical properties, porosity, and basic light-responsive nanite behavior. Produce initial samples of the recycled tire-rubber radiation-shielding composite. Phase 3: Process Optimization & Multi-Layer Development (Year 4–6) Optimize light parameters and nanite distribution for larger samples. Develop reliable multi-layer fabrication methods (Dilataero CFRP). Integrate radiation-shielding layers and maglev coatings. Refine magnetic connection interfaces at the segment level. Improve defect control and mechanical performance consistency. Begin testing Curved Trapezoidal Ring Segment prototypes. Phase 4: Pilot-Scale Modular Production (Year 6–8) Scale up production of Curved Trapezoidal Ring Segments. Establish repeatable manufacturing processes with controlled light systems (including polarization and patterning). Validate magnetic connection performance at segment scale. Produce segments with position-specific coatings (radiation shielding for upper modules, maglev coating for inner surfaces). Develop quality control and cost tracking systems. Phase 5: Full-Scale Construction & System Integration (Year 8–10 ) Begin ground-based construction of the tilted multi-layered tower. Progressively assemble segments using magnetic connections. Extend lower sections into the asthenosphere. Install radiation-shielding layers on upper sections. Integrate magnetic levitation systems along the inner coated guideway. Conduct full-system testing and performance validation. 9. Challenges and Mitigation Strategies Nanite scalability: Addressed through dense central 3D distribution combined with light-based signaling rather than physical propagation. Radiation protection: Provided by recycled tire-rubber composite layers on upper sections. Torsional stability: Supported by asthenosphere foundations and the 7° counter-rotational tilt. Interface bonding: Enhanced through nanite reinforcement and controlled light exposure during manufacturing. High manufacturing complexity: Mitigated through modular design and progressive process scaling. 10. Conclusion LuminaNitinol represents an integrated material and structural system that combines ultra-lightweight aerogel performance, carbon fiber reinforcement, embedded light-responsive nanites, and targeted radiation shielding. The use of Curved Trapezoidal Ring Segments as the official modular block shape enables efficient circular construction while supporting the 7° tilt and modular magnetic assembly required for a ground-based elevator reaching Low Earth Orbit. Further development will require coordinated advances in materials synthesis, optical process control, large-scale modular construction, and radiation shielding performance.

In many ways, constraints are the framework that gives design direction. In real estate and construction, design is essentially the process of solving constraints; topography, wetlands, utilities, zoning, setbacks, traffic flow, stormwater, budgets, soil conditions, permitting, structural spans, and tenant requirements Constraints also drive efficiency. They influence circulation, loading access, clear heights, and future expansion potential. The best developments are rarely the ones with no restrictions. They’re the ones where the design team used constraints intelligently to maximize functionality, cost control, constructability, and long-term value.

Super cool paper by @GoogleDeepMind on AI4math, via formal Lean proofs. The team also proved the first unconditioned special case of a quantum optics question in our research, which we asked in 2017. We're writing a paper about the physics behind it right now. Really wild! Congrats to @MoritzFirsching, @gtsoukal, @swarat and team! From my side this started back in March, after a busy week I decided to relax on the weekend leaning some @leanprover. DeepMind (especially Moritz and @Paul_lezeau) have prepared a collection of formal statements of many open math questions. I decided to contribute our own question from 2017 (about the constructability of high-dimensional GHZ states with minimal resources in quantum optics), and numerous other questions in quantum physics collected by @iqoqivienna under the name "Open Quantum Problems". My PRs were accepted, and i was pretty happy. Then some day, Moritz wrote a DM, they found some special cases. First, an analytical proof for which we knew a Gröbner basis numerical solution already, then several other solutions for which we didnt knew any solutions. The proofs rephrased the original problem (from combinatorics) into a very harmlessly looking linear algebra problem, and used several general tensor algebra ideas to make the non-existence explicit. In the end, it proposed a general, uncondictional (no constraints on the graphs) proof that said one cannot generate monochromatic quanutm graphs with dimensions d equal or larger than the number of vertices of the graph. Thats the first unconditional proof for any dimension, and probably the biggest contribution to the problem. More in our forthcoming paper. As a side note: I have also formalized the quantum question about existence of AME states. AlphaProof Nexus indeed did find a new AME state AME(11,5), according to the go-to list of Felix Huber. However, it turned out that the underlying Quantum Code was already discovered 2 years ago and the maintainer of the list didnt know about it. Shows that these tools are also great in connecting literature results.

Alaska LNG Project (also called AKLNG) is a major natural gas infrastructure initiative—not an oil pipeline—to transport stranded natural gas from Alaska’s North Slope to in-state users first, with a second phase enabling LNG exports. alaska-lng.com It is developed by Glenfarne Alaska LNG, LLC (a subsidiary of Glenfarne Group, LLC), which owns 75% and serves as lead developer, in partnership with the State of Alaska (25% ownership via the Alaska Gasline Development Corporation/AGDC through 8 Star Alaska LLC). Glenfarne took over as lead developer in March 2025 after signing definitive agreements with AGDC, shifting more development risk and costs to the private sector while the state retains a long-term stake. glenfarneenergytransition.co… The project is structured in two financially independent phases to accelerate execution and prioritize in-state energy needs: alaska-lng.com 1 Phase One (Domestic Pipeline Focus): A 739-mile, 42-inch-diameter mainline pipeline (potentially including a 63-mile, 32-inch Point Thomson Lateral) to deliver natural gas from the North Slope (Prudhoe Bay Unit gas treatment plant area) to Southcentral Alaska (Cook Inlet/Anchorage region). It will supply reliable, affordable gas to homes, businesses, utilities (e.g., ENSTAR), industry (e.g., Donlin Gold mine), and power generation amid declining Cook Inlet supplies. Pipeline construction planned in four simultaneous spreads/sections. glenfarnegroup.com Phase Two (LNG Export Addition): Adds the LNG liquefaction terminal and related infrastructure at Nikiski on the Kenai Peninsula, extending the total pipeline length to ~807 miles and enabling up to 20 million tonnes per annum (MTPA) of LNG exports (primarily to Asia). Includes associated facilities like a gas treatment plant (GTP) on the North Slope. alaska-lng.com Pipeline capacity is designed for approximately 3.3–3.5 billion cubic feet per day (Bcf/d) of natural gas, supporting both in-state use and full export volumes. gem.wiki Current status and timeline (as of mid-May 2026): All major federal permits are in place (FERC certificate, DOE export authorization). Worley Limited completed primary front-end engineering and design (FEED) for Phase One by the end of 2025 and has been provisionally selected for Engineering, Procurement, and Construction Management (EPCM) services; final engineering and cost estimating are underway. glenfarnegroup.com 1 Early pipeline-related construction/prep work (e.g., site preparation, mobilization) was targeted to begin as early as mid-April 2026 per a February 2026 FERC filing, with full mobilization around June 2026. Main pipeline construction (pipe-laying) is expected to ramp up in late 2026 across multiple seasons, aligning with Arctic conditions. naturalgasintel.com 1 Mechanical completion of the Phase One pipeline is targeted for 2028, with first in-state gas delivery in 2029. energy.gov 1 Phase Two (LNG terminal) Final Investment Decision (FID) is eyed for late 2026/early 2027, with first LNG exports potentially in ~2031. reuters.com FID on Phase One (pipeline) is still pending (originally targeted for late 2025 but delayed slightly into 2026), but momentum is strong with recent commercial milestones. Glenfarne aims for it once financing thresholds are met (typically ~80% of offtake contracted). alaskabeacon.com Commercial progress:Gas supply: Executed or advanced 30-year precedent agreements with major North Slope producers including ExxonMobil, Hilcorp Alaska, ConocoPhillips (recent 30-year deal announced around May 18–19, 2026), Great Bear Pantheon, and others—now sufficient volume for Phase One FID. enerdata.net 1 LNG offtake (exports): Preliminary long-term agreements/LOIs covering ~13 MTPA (out of 16 MTPA targeted for financing the full 20 MTPA project) with buyers including TotalEnergies (2 MTPA LOI, Feb 2026), JERA, Tokyo Gas, CPC (Taiwan), PTT (Thailand), and POSCO. These support Asian market diversification. glenfarnegroup.com Other partners: Conditional construction awards to major contractors (e.g., MasTec/Precision, Quanta/Price Gregory, Michels, VINCI, etc.); line pipe supply deals (e.g., Corinth Pipeworks, Europipe, POSCO steel); Baker Hughes (compressors/power); Danaos (LNG carriers and $50M investment). glenfarnegroup.com Cost estimates: Older public figures around $44 billion for the full project; Alaska Dept. of Revenue updated to ~$46 billion recently, though sponsors have not released the latest definitive number and critics note it could be higher. Some tax relief or state support may be needed. alaskabeacon.com Benefits emphasized by developers: Thousands of jobs during construction/operations, state/local revenues, reduced energy costs and pollution for Alaskans, and geopolitical energy security via reliable LNG to allies. alaska-lng.com The project has strong bipartisan Alaska political support and aligns with federal priorities for domestic energy and exports, though it faces ongoing scrutiny on final costs, binding contracts, and subsidies. For the absolute latest, check the official site (alaska-lng.com) or Glenfarne’s newsroom. This remains a gas (not oil) project and is unrelated to any second 48-inch crude oil line parallel to TAPS. 12 web pages Explain Alaska LNG project economics Compare Trans Alaska pipeline history Is the AKLNG 42 inch pipeline running adjacent to the 48 inch TAPS line, meaning within 100 meters parallel, or is the path quite different ? Thought for 45s No, the AKLNG (Alaska LNG) 42-inch natural gas pipeline does not run adjacent to the TAPS 48-inch oil pipeline within 100 meters parallel along its full route—the paths are only partially aligned in the northern section and quite different overall. alaska-lng.com Here’s the breakdown based on official project descriptions, regulatory filings, and route analyses:Northern section (Prudhoe Bay to ~milepost 400 south of Livengood): The AKLNG mainline generally parallels TAPS and follows the existing Dalton Highway/Trans-Alaska Pipeline utility corridor for roughly the first half of its length (up to about Livengood in Interior Alaska). This maximizes use of established infrastructure. ferc.gov 1 However, it is not continuously adjacent within 100 meters (~328 feet). Approximately 36% of the entire AKLNG route (~290 miles total) is “collocated” within 500 feet (~152 meters) of existing rights-of-way, including TAPS specifically for about 89 miles (mostly in the North Slope Borough and Yukon-Koyukuk Census Area). phmsa.dot.gov In those collocated segments, the new pipeline runs parallel at varying distances (up to the 500-foot threshold), with engineered separations for safety, constructability, and regulatory compliance. It crosses TAPS itself 12 times (plus 5 crossings of the TAPS fuel gas line). phmsa.dot.gov Southern section (south of Livengood onward): The routes diverge sharply. AKLNG turns south to roughly parallel the Parks Highway (through areas like Nenana, Denali, and Matanuska-Susitna Boroughs), then heads southwest, crosses Cook Inlet underwater, and terminates at the LNG facility in Nikiski on the Kenai Peninsula. alaska-lng.com 1 TAPS, by contrast, continues southeast from the Fairbanks area via the Richardson Highway corridor to its marine terminal in Valdez (Prince William Sound). The southern halves of the two pipelines are hundreds of miles apart and follow entirely separate alignments. In summary: The AKLNG route is deliberately designed to share the northern TAPS/Dalton corridor where practical (for environmental, permitting, and cost reasons), with limited close-parallel sections within the broader utility corridor. But it is not a tight “adjacent/parallel within 100 meters” duplicate of TAPS for any extended distance, and the overall paths become quite different after central Alaska. This is confirmed across FERC environmental impact statements, PHMSA filings, and project materials from Glenfarne Alaska LNG and the Alaska Gasline Development Corporation. phmsa.dot.gov For the most visual confirmation, the official interactive Alaska LNG project map (available on alaska-lng.com) overlays the route against TAPS and highways—clearly showing the partial northern overlap followed by divergence. The project remains focused on gas delivery to Southcentral Alaska (with later LNG export capability), independent of the oil-focused TAPS.
