The method of value engineering, where less expensive materials and methods are used without sacrificing functionality, certainly has its benefits.

While you must weigh the pros and cons of using it in each unique situation, the experts at CIVE are ready to lay out the overall argument for value engineering. The Houston-based, engineering-driven design build firm serves residential, commercial, and industrial markets, and relies on a commitment to excellence in all projects.

Its mantra — "Any engineer can create a design, but true expertise lies in creating designs that would incur the least cost possible, without compromising integrity of the structure" — reinforces that design is as much a science as it is an art.

Why should value engineering be used?
Value engineering allows commercial developers the capability to obtain more value for their design, contracting, and build-outs. This process not only helps provide advantages for the initial construction, but also add value on a longer term basis.

The initial costs of building a structure only accounts for 11 percent of the overall building costs of its life cycle. While that number may seem small, if this capital allocation is done incorrectly it can significantly impact the lifespan and ongoing maintenance costs that building owners can experience.

Value engineering provides great advantages to building owners and ultimately their tenants with a better quality structure. But let's be clear: The objective of value engineering is not to cut costs or to lower standards, but to provide innovative approaches and help identify ways to improve dependability, functionality, and performance.

When should it be used?
The process of value engineering can be applied in areas where a construction team typically experiences delays or excessive costs to help identify and alleviate the problem. The end result is a more efficient process that can reduce waste, rework, and design modifications that can significantly increase a project budget and/or cause schedule delays.

A few of the benefits
The benefits of value engineering are numerous, but in summary they can assist construction projects by:

  • Reducing expenses
  • Minimizing waste
  • Refining the project scope
  • Increasing stakeholder consensus
  • Maintaining budget allocations

Overall, this adds more value to the building owner with more savings over the lifetime of a structure with enhanced functionality. A company well versed in the practice of value engineering can use it to finish a project on time and on budget for their clients.

Implementing value engineering
Here's some good news: value engineering can be done at any part of the commercial construction process. While it would ideally be incorporated into the initial stages, it can be easily adapted to improve a project stage at any point. The design phase allows the architect or engineer to work with the client to come up with required features, functionality, and proposed solutions.

During the planning stage the general contractor and commercial developer come to an agreement on the expected project cost. The third stage of development is the construction phase, when the building takes place and any proposed changes can be included that don't affect the primary function and design of the structure.

Why it works
Unlike most, CIVE identifies value engineering as not merely a tool to cut corners, but a way to truly and effectively deliver engineering excellence by designing to the last inch — without over-designing or jeopardizing integrity of the structure — that can put redundant budget pressures on projects.

CIVE's ability to truly value engineer each of its projects comes with experience and technical expertise, which has saved its clients hundreds of thousands of dollars in investment capital over time.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
