The prevalent usage of Personal Mobility Device (PMD) in Singapore has created a pain point for residential estate town councils in the maintenance of lift mats. The frequent riding of PMD into lifts has resulted in wear and tear leaving behind stubborn stain-marks on the lift mats. With the projected rise in the usage of PMDs, the cost of replacing damaged lift mats is expected to rise too.

The existing mat material used in the lifts is unable to withstand the wear and tear due to the frequent riding of PMDs into the lifts, hence, leaving behind stubborn stains and affect the aesthetic of the lift. It is also not cost efficient to replace the lift mats whenever there are such stain-marks.

What We Are Looking For

The Challenge Statement Owner is seeking an innovative material which is elastic and has high durability to sustain the frequent riding of PMDs into lifts. The material shall withstand abrasion due to the riding of the PMD into the lifts. In addition, the new material shall not compromise the aesthetic of the lifts. The new material and its installation shall also not be cost prohibitive to implement in residential buildings.

The lack of maintenance for kitchen exhaust ducts has often resulted in a built-up of discharged greases and fumes around its exhaust filter and ducting. This has compromised the efficiency of the exhaust duct to filer excessive fumes and unpleasant smell from the fumes discharge. The excessive built-up of greases within the exhaust ducts will pose a fire hazard as well.

Hence, there is a need for a solution to facilitate maintenance to be carried out promptly and effective to upkeep the efficiency of the kitchen exhaust.

What We Are Looking For

The Challenge Statement Owner is seeking a predictive maintenance solution to improve the maintainability of the kitchen exhaust ducts. The proposed solution shall trigger alerts to the maintenance team to take prompt actions before the aforementioned undesirable outcomes occur.

Air-conditioning makes up the largest proportion of energy consumption in most residential buildings. In an effort to induce natural ventilation into buildings and reduce dependency of air- conditioning, wind data is often collected to understand natural ventilation. However, the wind data which is currently available is based on seasonal wind direction with little relation on how surrounding structures could alter the wind speed and direction. A more comprehensive wind data could be collected through on-site logging of wind data though the approach is often time-consuming.

Hence, there is a need for a more efficient way to understand natural ventilation in order to maximising its potential to change the design of air-conditioning. In this way, energy efficiency would be increased with reduced dependency of air-conditioning.

What We Are Looking For

The Challenge Statement Owner is seeking an efficient way to collect wind data and eventually develop a “national” wind data model for Singapore. The wind data model shall be maintained and constantly updated to facilitate architects and engineers in shaping their building designs by incorporate natural ventilation as a passive design solution for new buildings

Current processes of as-built verification is done both visually and manually only covering 5% of the space. Even when a 3D scanner is used to survey 100% of the space, BIM managers/modellers often find themselves spending weeks sitting visually comparing 3D models against 3D scans to detect deviations before updating their as-built models. 

Hence, such methods are labour-intensive and costly due to time-based survey services costs. In addition, deviations are not detected efficiently as reports usually take weeks to produce. 

As the industry moves from verification of 2D blueprints to 3D BIM, there is a need for these 3D models to be accurately and progressively verified as part of as-built verification process in order to detect and resolve deviation thus avoiding major reworks. Furthermore, with an up-to-date and accurate 3D BIM (i.e. digital twins) it will ease the handover to between Operation Expenditure (OPEX) to Capital Expenditure (CAPEX).

What We Are Looking For

The Challenge Statement Owners are looking for a solution to achieve greater Operational Efficiency in their 3D BIM verification process:

The proposed solution should be able to:

  • Increase as-built capture coverage to 100% hence reducing the need for on-site survey. 
  • Utilise Artificial Intelligence to identify dimensional deviations and update 3D models quickly so BIM managers / modellers make timely decisions. 
  • Utilise reality capture hardware tools such as Drones, Photogrammetry technologies and scanners

Today, pre-casters prepare the moulds for precast concrete components including concrete PPVC modules using their interpretation of hardcopy drawings. Once the moulds are completed, the Resident Technical Officers (RTOs) would conduct visual inspection on the assembled moulds with reference to the drawings. The common items inspected by the RTOs include dimensions of the moulds, reinforcement bar sizes, spacing and lapping length, cast-in-accessories, concrete cover, services openings and cleanliness etc.

It is often common for the assembled moulds to fail the quality checks due to inaccuracy of interpretation and human errors. This leads to manpower and time loss in rectifying the non- compliant moulds. Furthermore, RTOs may overlook minor details which results in major rectification especially when the precast concrete components have been installed on site. In addition, precast is done overseas and there are very few or no Resident Engineer (RE) or RTOs who would like to travel to carry out this structural inspection. On top of that, these RE or RTOs have to be stationed full time on-site and the travelling takes too much time and is not productive.

What We Are Looking For

The Challenge Statement Owner is seeking a holistic solution including digital means that is able to improve the productivity and effectiveness of the inspection process as well as the accuracy and quality of works to reduce any manpower and time loss for rectification. Instead of having localized checking inspection, challenge owners are looking for a continuous QA/QC check embedded in the process with the new proposed technology or solution.

The Architect, Engineers and Contractors (AEC) industry has been readily adopting BIM for design and fabrication. During the design stage, the Mechanical, Electrical and Plumbing (MEP) system design is often subject to changes. As there is currently no effective tool to facilitate the update of changes from the original schematic design drawing (SDD) to the BIM design model, there are always discrepancies between both the SDD and BIM design model. This has caused unnecessary challenges during the maintenance of MEP systems.

The lack of information links between the SDD and BIM design model has posed a real challenge to design an effective tool to facilitate the synchronising of design changes between both design formats.

What We Are Looking For

The Challenge Statement Owner is seeking for an effective tool in which changes made in the MEP BIM design model could automatically be shared and reflected in the SDD real-time, automatically and accurately. The network of different MEP systems in the final schematic design model shall be generated based on the connections of piping, ducting, cabling segments or other components within the MEP BIM model. Eventually, the developed platform shall provide only one common data source to facilitate an effective maintenance of MEP systems.

It is estimated that 60,000 incidents occur annually within construction sites worldwide. In Singapore alone, workplace injuries rose from 12.4k cases in 2017 to 12.8k cases in 2018 (+2.5%). Amongst them, 41 people died due to fatal injuries. At the same time, according to a research report, large construction projects take 20% longer on average to finish than initial estimates due to poor manpower allocations and/or unforeseen safety issues.

In order to enhance construction site safety and productivity, there is a need to provide the project team with clear information such that:

  • Number of workers that are within a construction site, and which subcontractors they belong to.
  • The location of the workers to ensure that each individual is accounted for and are within area of work.

Precast modules are usually lifted by wires with the safety of the lifting process very much dependent on the experience of the crane operator. Further, existing operations does not take into account factors such as; unbalanced loading caused by uneven distribution of stresses across chain pulleys or non- visible damages to cable ropes due to wear and tear. 

Hence, any unintended / accidental release of these precast modules during lifting operation would compromise the safety of the lifting equipment, operator and construction crew. 

It is essential to enable the crane operator to make better decisions when lifting precast modules for installation thereby making the lifting process safer.

What We Are Looking For

The Challenge Statement Owner is seeking for a solution that enables the crane operator to make adjustments based data collected when lifting precast panels. These data should include factors such as; the distribution of weight when lifting precast modules and stress distribution across the lifting beam.

At present, inspection and maintenance of the complex building façade is a labour intensive and dangerous activity that requires a skilled professional using equipment such as gondolas and ropes to work at heights in order to access the building’s surface. Existing façade inspection methods which presently used are largely limited to visual checks of the external surfaces as well as localised examinations on the support system and condition of the rear face of the façade. These checks which are usually intrusive, requires the opening of holes/cavities in the façade in order view these areas using a borescope.

Hence, despite safety training and preventive measures maintaining a building façade is still a high risk activity and labour intensive task. Therefore, there is need for a solution which is able to provide greater accuracy for the assessment of the entire internal and external façade condition that minimises the need for human labour.

What We Are Looking For

The Challenge Statement Owners are looking for solutions to either enhance or provide an innovative alternative to existing methods. Reducing risk and effectiveness of existing methods is imperative. The proposed solution should take the following aspects into consideration: 

  • Be able to conduct comprehensive inspection of the cavity between the façade and the support structure. 
  • If imaging technologies are proposed, it should be able to take images under low light conditions and automatically correlated its location on a 3D building model.
  • Data analytics should also be considered for interpretation and identification of defects. The engine should be able to assess the quality of collected data and generate a report to indicate the level of criticality. 
  • Inspection system should be able to intelligently through data analytics. 
  • Robotics is a possible alternative, but the proposed solution should consider sustainability and reliability for various façade and environment. If robotics platforms are used, it should be capable to manoeuvre around building envelopes, including those with irregular profile. 
  • Design consideration is another aspect that should be looked into, for instance, solutions should be able to assist architects and designers to take into account maintenance of the building façade. This translates into savings by improving a building's life cycle cost and reduce cost required for façade cleaning and maintenance.

Due to the nature of environment and the usage of buildings, existing solutions are unable to accurately determine the condition or reliability of the materials such as steel, reinforced concrete (RC) for the beams, columns and other essential structures that affect structural integrity of a building. Inspection is usually done by a PE (Professional Engineer) through visual inspection periodically, usually in a range of 5 years. Many challenges arise in determining a building structural integrity, one of them is the lack of physical access or unseen parts of the area or structure. Inspection is often limited to visual inspection of accessible areas.

Currently, there are a few existing methods in the market that require sensors to be embedded into the structure but this causes other issues such as sensor data reliability and cost effectiveness for sensors to be embedded into all structure.

In order to determine the volume of aggregates stocks, vehicles loaded with aggregates stocks have to be weighted twice, before and after unloading of the aggregate stocks at the unloading bay. Since the weighing platform and unloading bay may not be located next to one another, vehicles have to spend unnecessary time travelling between the weighing platform and unloading bay. In addition, the measurement results are not updated real-time and are often prone to human errors.

Hence, despite the effort to minimise disruptions caused administratively, the process of keeping track of these daily aggregate stock is still tedious and time-consuming due to the constant inflow and outflow of these aggregates.

For Prefabricated Prefinished Volumetric Construction (PPVC), modules need to be reinforced with mesh and reinforcing bars (also known as rebars).

The steps involved in fabrication and the assembly free-standing volumetric modules are:

Step 1: Interpretation of rebar drawings by skilled personnel
Step 2: Assembling the mesh and rebar to form a structured cage
Step 3: Install the rebar cage into the mould
Step 4: Closing of steel mould and installing of services ducts

Step 5: Checking and closing of mould

The steps require the effort by a 4-man team that takes 8 – 10 hours a day to prepare the rebar cages.

It is extremely time consuming process to assemble rebar cages. Moreover, as the interpretation of the rebar drawings are conducted by human, it leaves room for misinterpretation of drawings could result in missing rebars and links. If the checks fail (often due to the inaccuracy of rebar drawing interpretation), workers have to amend and rework these the cage from scratch. This means more time required to amend the rebar cage.

3D printing with concrete is an emerging technology which could potentially reduce labour and form-work costs, while increasing reliability of concrete infrastructure. Though high in compressive strength, concrete is fairly weak in handling tension. In order to overcome this challenge, concrete is usually reinforced with plastic or metal fibre.

Though significant progress has been made in non-reinforced concrete 3D printing, there is limited success in incorporating reinforcements into concrete 3D printing. 3D printed reinforced concrete often has weak material properties due to segregation and non-uniform distribution of added fibre reinforcements. This has prohibited their usage for building and construction application.

Monitoring of the corrosion status of reinforcement bar are estimated from open circuit potential measurement and linear polarisation resistance. Both these tests are intrusive as they require hacking off the concrete cover of the reinforcement bars before reinstating them each time. Alternatively, corrosion status could also be estimated by embedding connection wires and leaving them exposed for the continuous measurement.

Such methods of monitoring of corrosion status are complex. Hence, a simpler and more accurate approach is needed for on-site corrosion monitoring to improve productivity. Ideally, this newly developed method should be connectionless so as to address the stringent site safety requirement when monitoring of corrosion status in areas with limited access (e.g. tunnels or structures in operation).

The Challenge Statement Owner is looking for a solution that should fulfill the following specifications:

  • The system should also be complete with a platform to enable advanced data sharing and communication to enable real time monitoring.

Mass Engineer Timber (MET) is a lightweight material which is preferred to reinforced concrete when constructing long-span structures due to its lifting capacity. However, this still reduces the available crane time needed for hoisting other heavyweight materials on site when lifting and shifting MET components during MET installation.

Existing tools which are available that aid in lifting and shifting of MET components are not stable and often require at least 2 workers to operate. This tools still utilize crane, which leaves less crane time available for other activities thereby reducing onsite productivity.

The Challenge Statement Owners are looking for a solution which could improve the efficiency of transporting, lifting and installing MET components. Some of the basic requirements for 

  1. Vertical movement – Sufficient lifting capacity for MET components of up to 4 tons (based on MET density of 500kg/m3, slab dimension 12m x 3.4m x 0.2m)
  2. Horizontal movement – Sufficient lateral movement capacity, requiring at most 1 worker for transportation of MET within the same floor.
  3. Reduce crane time for installation, by at least 50% Easy to maneuver and allow great flexibility in installation height up to 4.5m.

Singapore has achieved success in the use of alternative building and construction materials such as, recycled concrete aggregates and washed copper slag for various applications.

With the growing emphasis on Circular Economy and Sustainability, a holistic approach is required to close the material loop by optimizing material usage during and beyond the materials’ lifespan, and containing waste generation by converting various wastes into building and construction resources.

If non-Built Environment wastes can be used for building and construction applications, it could reduce the reliance on conventional materials such as sand and granite as resources. Consequentially, reduce environmental impacts of construction projects.

What We Are Looking For

The Challenge Statement Owner is looking for a proposed solution which should incorporate locally generate wastes to be used as alternatives in the generation of recycled building and construction materials. The product should conform to LTA’s Materials & Workmanship Specifications and/or local environmental standards and / or building codes and regulations for non-structural concrete applications. It would be advantageous that the product can demonstrate satisfactory/improved performance compared to conventional building and construction materials.
