Applications open for new £1.2bn framework

Applications open for new £1.2bn framework for Modern Methods of Construction of public sector homes

Specialist contractors can now apply to join a new £1.2bn framework to deliver offsite- constructed homes that will provide thousands of homes to benefit communities across the UK.

 

The new NH3 (Modern Methods of Construction (MMC) of New Homes) framework from public sector construction framework provider LHC will operate across England, Scotland and Wales, delivered through LHC London and South East (LSE),  Scottish Procurement Alliance (SPA), South West Procurement Alliance (SWPA), Consortium Procurement Construction (CPC) and Welsh Procurement Alliance (WPA).

 

The framework, which replaces NH2, will address some of the new housing challenges within the public sector at a time of high demand and increasing emphasis on the need for sustainable methods of construction and a greater supply of housing stock that is environmentally fit for the future.

 

Aiding the construction of a range of different housing types, NH3 covers low-rise and medium/high-rise dwellings through to specialist accommodation such as care homes. It will support public sector procurers to increase the use of modern methods of construction in their contracts and help to deliver low and net zero carbon homes with high levels of pre-manufactured value.

 

The framework will also create the opportunity for procurement teams to access a wider range of MMC solutions and suppliers, encouraging greater collaboration between suppliers and clients.

 

Dean Fazackerley, head of technical procurement at LHC, said:

 

“The NH3 framework will build on the success of NH2, which has so far enabled £93.5m-worth of projects with a total forecast value of £277m. It has contributed to the number of low-carbon, modern apartments and homes for housing associations and local authorities across the country, using modern methods of construction and offsite techniques to produce cheaper-to-heat homes for the communities they serve.”

 

Developments so far procured or delivered through NH2 include 400 units, currently being built across a four-year period by modular offsite construction specialists Rollalong, for Magna Housing Association and Wiltshire Council in the South West. In the London Borough of Bromley, the framework has also been used to deliver 25 one and two bedroom affordable apartments, as part of the ‘Bromley Homes for Bromley People’ programme. Among the environmental features incorporated in the build from Module-AR are PV panels and herb gardens.

 

Finally, NH2 has also delivered the award-winning Hope Rise scheme in Bristol, where 11 affordable, low-carbon apartments from Zed PODS have been installed as permanent living spaces for young workers and vulnerable households.

 

Dean Fazackerley added:

 

“NH3 will initially cover a range of MMC categories and features four distinct workstreams we hope will encourage both manufacturers and those that can deliver main contractor services for MMC to apply. We also hope SMEs will apply and take advantage of the opportunities available to them through this new framework.”

 

The four workstreams covered by the NH3 framework are:

 

  • Workstream 1 – Three-dimensional (3d) modular systems – category 1
  • Workstream 2 – Two-dimensional (2d) panelised systems – category 2
  • Workstream 3 – Main contractors delivering MMC solutions
  • Workstream 4 – Groundworks and site preparation for MMC housing projects

The deadline for applications to join the framework is 14 October 2022

Energy Crisis Wont be Avoided by Fracking

Even if we stick our heads in the sand regarding its environmental impacts, fracking will not ease rising UK energy bills.

Desperate times result in ineffectual measures

In a time when the energy crisis is paired with contracted global outputs, reduced household purchasing power, and supply imbalances, governments are scrabbling for solutions. A recent example of this has been the UK lifting its ban on fracking. Fracking, which was banned in 2019, was re-introduced as part of Prime Minister Liz Truss’ package of measures to tackle rising energy prices. However, as in 2019, the announcement has been met with plenty of backlash as both an ineffective and harmful solution. Even if we stick our heads in the sand regarding the environmental impact of fracking, it will not ease rising energy bills in the UK. The price of gas is determined on the European market and any excess will be quickly purchased at high prices. Moreover, many expert geologists are seeing faults in the plan at even earlier stages, stating that the UK does not have the right type of shale, and, unlike the US, it will be a costly and complex process that will result in much lower oil and gas output than expected.

Fracking will cause more problems than it is worth

But it is the environmental impacts of fracking that cement it as an intolerable solution to the energy crisis. The risks of fracking run deep. It impacts the air, water, soil, vegetation, wildlife and humans too, especially with the contamination of groundwater. If that was not enough of a deterrent, there is also an indeterminate risk of earthquakes. A recent study by the British Geological Survey noted that in some areas of fracking ‘the resulting hazard from induced earthquakes … is significantly greater than the hazard from tectonic earthquakes’. Fracking brings more risk and disappointment than solutions, and instead of rehashing past solutions, nations must look to the future with a buildout of renewable energy capacity, an improvement of energy storage infrastructure, and the deployment of more clean energy technologies in the face of current and future energy crises.

Going Modular – A US viewpoint

Going modular – skid vs volumetric?

By Brandon Gries, Cupertino Electric

 

Like a classic Bell curve, modern construction approaches can range from pure volumetric modular on one end and pure traditional construction on the other

In these uncertain times, nothing is guaranteed. However, one thing that has been predictable over the last few years has been a shortage of skilled labor for construction projects. This is especially the case in parts of the US where large data center construction is booming.

For many data center owners, the shortage of skilled labor in prime locations has driven a shift toward the use of modular construction techniques. By moving much or all of the construction and labor associated with data center builds offsite to fully staffed manufacturing facilities, owners can reduce their labor risk and reap other rewards.

Once modular construction enters the conversation, the rationale for this approach becomes compelling. Modular construction doesn’t just reduce labor risk, it also enables the compression of construction timeframes, increases quality at source, enables improved quality controls and product testing, and decreases weather-related delays that plague construction projects in many parts of the country for large portions of the year.

Maximizing modular

The challenge for businesses choosing to use a modular approach is knowing how to use it appropriately to maximize the positive impacts and minimize the potential pitfalls. The primary decision centers around which approach makes the most sense for the project at hand: volumetric or skid-based modular construction.

It is very tempting, once a customer has committed to utilizing modular construction, to want to modularize everything. This includes all elements of the shell of the building, in addition to all of the utilities and functions inside. This is a volumetric modular approach. For some projects, this may well be the best approach. But for others, this all-in modular approach can introduce its own set of issues and constraints that make it less than ideal. In those instances, a skid-based approach – where elements inside the building best suited for modularization are identified, built offsite into large modules called skids, then shipped and installed on a site where a shell has already been constructed – is best.

How to determine which approach is best is critical to the ultimate success of a modular project. Our experience building modular options suggests three elements that businesses should consider when simplifying their decision:

1 Does your project REQUIRE a volumetric approach?

This is quite different from asking whether you COULD use this approach. It may be surprising to hear that some aspects of volumetric modular construction are significantly less efficient than their traditional alternatives. This isn’t a result of bad planning or design by modular builders but is the result of specific design imperatives. The volumetric approach requires that each building module is fully framed to safely support itself. While there are good reasons for this, it means the volumetric approach inherently requires different mix of materials, which can be less efficient. Pulling in the opposite direction is the extreme efficiency of certain processes already built into traditional construction. Structural steel is a great example. A traditional beam and column structure has been designed to minimize the amount of steel needed to build the total volume. This means you will spend more on structural steel in a volumetric solution than in a beam and column structure.

So, the question becomes whether the benefits to your project of using a volumetric approach outweigh the inefficiencies that come with it. If for example your project requires the smallest solution possible, volumetric may be the way to go. Alternatively, if the goal is to reduce the number of inefficient/expensive components in the project to a minimum, a hybrid approach utilizing skids and a traditionally built shell may be a better option.

2 How important is operational efficiency to you?

Have you ever wondered why your super-thin laptop is significantly less powerful than its desktop equivalent, despite being more expensive? One reason is space. Computing systems produce a lot of heat, and efficiently removing that heat requires a lot of air. The same principle applies to data centers. When building a volumetric system, you must factor in rules and regulations around what size of item can be transported. These constraints lead to building smaller, tighter spaces which may lead to much less efficient mechanical systems.

Similar parallels arise when it comes to maintenance. Like big computers, large data centers are easier to access and repair. Smaller spaces can mean more challenges for upkeep and repair than spaces with greater volume and larger maintenance clearances. It’s all about trade-offs. If your project has constraints that require tighter spacing, a volumetric approach may be ideal. If you can afford the extra air, a skid-based approach can provide real operational benefits. When choosing the right modular approach, it’s essential to identify the optimal balance between your project’s space efficiency and operational efficiency.

3 How big and widespread is your program?

Everyone involved in construction understands that permitting is a necessary element of any project. If you are building a single data center, then the permitting process will look similar, whether you use a traditional or modular manner. However, if you have a larger program and want to move toward modular, permitting is a real issue. If you want to use standardized volumetric modular building components, you will need to identify all the jurisdictions where you plan to build and ensure that your designs pass inspection in all of them. This may add cost and complexity to the design. In addition, you will likely need to get permits before construction can start and schedule inspections at key milestone activities.

If the number of installation locations is small or predictable in advance, these considerations may not be an issue. However, if you want the flexibility to build multiple identical components and redirect one originally identified for an Oregon location to Texas because that project has jumped ahead in schedule, then a skid-based approach might be best. A skid-based modular approach can provide more flexibility, reduce permitting headaches, and deliver greater ability to build ahead to meet capacity. Understanding the scale and scope of your project is key to identifying the approach that best for you.

The best approach

By now it is probably clear that while using a modular approach to building provides an elegant solution to address some constraints of traditional construction, there are different flavors of modular data center construction. Like a classic Bell curve, modern construction approaches can range from pure volumetric modular on one end and pure traditional construction on the other. In the middle of the Bell curve, the modular approach that we’ve seen work most often is one that uses a mix of the best, most efficient traditional construction aspects combined with targeted, skid-based modular. This hybrid zone contains the sweet spot for most projects, but where your project sits, and how to arrive at the right mix depends on a range of factors. The key to success is to understand the pros and cons of each approach, and the trade-offs inherent in each.

Find the best combination for your data center project and modular can help make it a success.

50 MW SOLAR FARM PROJECT

BayWa and Grüne Energien Solar (GES) have secured consent for their near 50MW Perrinpit Road Solar Farm project in south-west England.

Construction of the South Gloucestershire scheme is expected to start in early 2024, with commercial operations targeted for later that year.

BayWa said 20 jobs will be created during the site’s development, along with up to three long-term jobs throughout the operational life of the 49.9MW project.

The planning application was supported by a series of biodiversity commitments, including the planting of new trees and hedgerows at the site.

BayWa r.e. UK managing director John Milligan said: “This is an exciting project for our team and we are delighted to work with Grüne Energien again.

“This is our second 49.9MW project in the UK delivered through our joint venture.

“The implementation of renewable energy projects like Perrinpit Road is essential to meeting the UK’s legally binding net-zero carbon emission goals by 2050. It is encouraging to see the local commitment in South Gloucestershire to meet these goals.”

GES managing director Marco Pannicke added: “This is a great achievement and shows the spirit of our joint venture with BayWa r.e.

“There are many more projects in the pipeline and it is an honour for us to develop renewable energy projects in the UK.”

‘Smart-washing’ not just a box ticking excercise

“If we’re going to make progress, we have to have a system that recognises greatness,” the co-founder of Smart Building Certification said at the Sustainable Places conference in Nice, France.

Elizabeth Nelson called for smart buildings that meet user needs and sustainability standards, arguing that simply having a checklist of things to include in a building fails to achieve that.

She said that the Smart Building Certification uses both qualitative and quantitative measures, breaking down what’s already in a building and where it can make improvements.

“Smart is solving a problem or optimising something. It’s not a technology,” she said, speaking at the 10th Sustainable Places Conference from research and innovation company R2M Solution.

“We’ve had greenwashing for quite a while. Now, I believe we have some smart-washing as well, especially in the commercial sector.”

Rather than tick certain boxes, buildings seeking certification undertake a “very large, exhaustive, dynamic questionnaire”. That questionnaire asks about the building’s tech, presenting follow-up questions to understand what the building does and why. “I don’t think a smart building certification be a checklist,” she said.

The Smart Building Certification scheme evaluates buildings based on six measures:

  • Building usage (how people use the building)
  • Building performance (sustainability)
  • Building environment (how well the physical space meets users’ needs)
  • Health, safety and security
  • User behaviour and collaboration (how well buildings allow people to work together)
  • Integrative design and connectivity (how well all the tech in the building is integrated with each other – “the least number of solutions for the maximum benefit”)

Other takeaways

1. Don’t underestimate a retrofit

“This is one of my favourite things about smart buildings we’re seeing right now,” Nelson said. “Everyone is saying, ‘Oh you can’t have a truly smart building if it’s a retrofit’, or ‘You couldn’t have a truly sustainable building.’ But you can.”

She used Hausmanns Hus in Norway as an example. Developer Hathon is aiming to achieve a BREEAM Excellent certification for the refurbished office, set to open at the start of 2023. Wellness and flexible workspace are two priorities for the building, and Hathon even developed tech in-house to ensure the space delivered what it needed.

2. Developers who retain their buildings have an advantage

Nelson said: “A lot of times, builders are nervous to [put] a tonne of different functionality into a building that might get lost in translation if it’s transferred.

“So, the builders that are actually owning their own properties and keeping them have a little bit more control and maybe even pride of ownership and confidence in that.”

3. Be transparent about data

Returning to Hausmanns Hus, Nelson said the building will display real time air quality data. Seeing performance data is crucial, she said, and “something that can have a drastic implication on how people feel about environments”.

She added that landlords should explain people in the building what data they collect and why. “We had a great living lab where the students at a university ripped sensors off the wall because they didn’t want to be recorded in this area,” she said. People need to know they can trust whatever data collection happens where they work.

4. It’s not about the amount of tech you cram into a building

Putting in thousands upon thousands of sensors will not automatically get you a Platinum Smart Building Certification. “We have buildings that score very similarly. Some of them have 30 technologies; some of them have six,” Nelson said. It’s about creating a functional building, rather than a blatantly techy one.

5. The idea of smart buildings is centuries old

The first smart building, according to Nelson, was built 400 years ago by Dutch inventor Cornelis Drebbel, who invented a chicken incubator that could regulate temperature.

JAPAN – EMBRACING OPEN BIM

The “Steel Nest” of the Japanese Sanei Construction Steel Structure Division

(c) Takenaka Corporation

Takenaka Corporation embraces OPEN BIM and Building Lifecycle Intelligence with Nemetschek Solutions

 

Munich/Osaka, September 12, 2022: Takenaka Corporation, one of the largest general contractors in Japan, is strongly relying on the solutions from the Nemetschek Group in building its BIM strategies to provide first class architectural, engineering, and construction services. Leveraging an open Building Lifecycle Intelligence approach with a Digital Twin, the company is creating impressive buildings and structures across the globe.

Takenaka Corporation has been committed to realizing customer dreams and shaping the world since their very beginnings, more than 400 years ago. Today, Takenaka Corporation employs more than 2,400 architects. They use solutions from the Nemetschek Group brands dRofus, Graphisoft, and Solibri to execute on their Design-to-Build BIM strategies providing end-to-end services to their clients. Takenaka Corporation maintains an enterprise agreement, providing all employees unlimited access to these software solutions for design, BIM authoring, coordination, and asset data management.

For the “Steel Nest” – the new office building for the Japanese Sanei Construction Steel Structure Division – the experts at Takenaka Corporation leveraged digital solutions and an OPEN BIM (Building Information Modeling) approach from the first design draft to construction. The customer required the building to also function as a show room illustrating their steel frame processing technology. One of Takenaka’s major challenges was combining this showroom with Sanei’s wish to create more opportunities for employees to encounter. The result is an office building that goes beyond the conventional concept of architecture, presenting an astonishing Voronoi structure (polygons of different sizes assembled).

Takenaka Corporation used Archicad from Graphisoftto create the design of the steel frames. The models were then checked for BIM quality and coordination with Solibri, ensuring that they fulfill project requirements. Due to the complexity of the structure and the individual solutions used in each phase of the project, Takenaka Corporation decided to completely rely on open interfaces and BIM. The 3D model made it easier – and quicker – to form a consensus about the design among the parties involved.

“For us, the construction of the ‘Steel Nest’ has proven that our company’s philosophy and our Integrated Design-to-Build approach works even on demanding projects with complex requirements,” says Mr. Hiroyuki Shimizu, Executive Managing Officer of Takenaka Corporation. “Looking at the entire lifecycle of buildings has always been in our DNA. With OPEN BIM and the use of Nemetschek solutions, we will be able to carry this philosophy into the digital era and become a fully data-driven company.”

“We are very proud to be working closely with the inspiring, innovative Takenaka Corporation. We share the same philosophy of leveraging data across the entire building lifecycle,” says Viktor Várkonyi, Chief Division Officer Planning & Design Division and member of the Executive Board of the Nemetschek Group. “It is great to see how Takenaka delivers outstanding results by enhancing BIM quality and the collaboration between the individual disciplines in the building process.”

The future holds many exciting projects for the industry experts: Takenaka Corporation is involved in the design and construction of various pavilions for Expo 2025 in Osaka. In addition, they are looking to expand the strategic partnership with the Nemetschek Group to also involve solutions from ALLPLAN and Bluebeam.

AI fundamental for EU to reach its 15% gas reduction target

Artificial intelligence (AI) could be used as a fundamental strategy for EU member states to help reach the voluntary 15% gas reduction target placed on them by the EU Council in July 2022. Arloid Automation, of London, advocates the use of AI coupled with any building management system to control and make significant savings of up to 30% on energy and coolant use.

According to the Council of the EU’s press release (26 July 2022), ‘Member states agreed to reduce their gas demand by 15% compared to their average consumption in the past five years, between 1 August 2022 and 31 March 2023, with measures of their own choice’. The importance of reducing energy demand cannot be overemphasised largely due to supplies from Russia being significantly reduced, erratic and they may be stopped altogether.

Most energy saving measures have a significant capital outlay but Arloid’s AI can be implemented without cost until savings are made. This makes it one of the cheapest and easiest ways for EU states to significantly reduce energy consumption with no upfront costs. Once savings are established – this is normally after 30 days – a percentage fee can be charged.

A reduction in energy use is easily achieved through a series of simple steps. Firstly, a virtual building identical to the one where savings are to be made is produced. This digital building has the same construction materials, location, climate and personnel attributes as the real one. From this virtual building AI makes a series of simulations based on live data from the real building. This process takes about a month.

The AI intuitively adjusts the heating, ventilation and cooling settings, thus resulting in real savings. In the real world building services engineers or property managers have previously adjusted these settings but this can take some time. Imagine a world where all these changes are automatically done – then imagine what can be achieved. It’s not only saving energy and money but improving comfort too.

Arloid’s AI uses Deep Reinforcement Learning to automatically manage the operation of HVAC systems in a wide range of buildings via a secure Virtual Private Network (VPN). It then makes decisions based on reinforcement behaviour and real-time data to provide faster optimisation and better HVAC performance. By controlling each HVAC device in the system and dividing the building into distinct heating and cooling micro-zones, arloid.ai provides more control of the environment and better user comfort.

The technology is gaining ground not just in Europe but across the world with actual savings being achieved over 56 million square feet. This includes real estate and many types of commercial building such as retail premises, hotels, medical centres, warehouses. By reducing energy use the cost savings can counter the effects of energy supply issues, higher prices and inflation.

AI should now top the political agenda right across the EU to help member states reach their voluntary gas reduction targets of 15%. It’s not as difficult to achieve as it may first seem because new technology can play a huge part for very little outlay. At any rate it’s an obvious and achievable first step towards EU goals and for those countries encouraging dimmed lights and shorter showers there is another way!
