The multi-million-dollar Trestrail Housing Development Corporation (HDC) project has stalled after construction firm Ricky Raghunanan Company Limited was flagged and directed to undertake remedial works for structural defects.
Two independent engineering reports found major issues with the construction work carried out by Ricky Raghunanan Company Limited on zones D and E-1 of HDC’s Trestrail 1R development.
The independent engineering report raised concerns about the foundation being unable to support the applied loads of the two-storey structures and raised issues with insufficient or lack of reinforced beams among other matters contrary to international standards.
Since Ricky Raghunanan has been asked to undertake remedial works on the structurally flawed construction project, the proposed 110-apartment Trestrail development 1R Project, estimated at $100 million, has been left hanging.
The HDC is now running more than four years late on its promised delivery date while some 180,000-plus applicants throughout the country are awaiting homes.
The Trestrail Housing Development, which started in June 2017, is located off La Resource Road in D’Abadie.
According to the HDC, 936 residential townhouses and apartment units were supposed to be constructed in two packages—Package 1R–452 housing units and Package 2–484 housing units.
In September 2018, the HDC gave out 80 of the single-family units.
Other parts of the project remain incomplete, including zones D and E-1 of Package 1R, awarded by HDC to contractors Ricky Raghunanan Company Limited in 2020 under a design-build-finance FIDIC contract to deliver 110 townhouses.
The HDC purchased the 128-acre former horse farm estate from the Trestrail family in September 2011 for a reported sum of $77 million.
Two weeks ago, Opposition MP Roodal Moonilal called for a probe into the stalled project, alleging that millions of state funds could be wasted. He also accused the HDC of failing to exercise its “fiduciary duty” with respect to the condition of about 100 units at the housing project.
Contractor must bear cost of rectifying defects—HDC
Housing Minister Camille Robinson-Regis, defending the HDC’s position, said the contractor had to fund all remedial works. She added that the company had not received any payment for the work done so far.
“The HDC has entered into a situation where the contractor must remediate at his own cost, so this talk that Oropouche East is saying that the taxpayers will have to pay millions and millions of dollars is totally fabricated and totally untrue,” Robinson-Regis said in Parliament during the 2024 Budget debate.
In response to questions from the Sunday Guardian, the HDC confirmed that it awarded a design-build-finance FIDIC contract to Ricky Raghunanan Company Limited in 2020 for the construction of 110 townhouse units.
The HDC said its board of management had concerns about certain structural issues on the project and as a result, commissioned CEP Limited to conduct a study on the structural issues affecting the project.
“The study identified a number of defects and, in accordance with the employers’ claim of the design-build-finance contract, the HDC is entitled to make a claim for its cost of engaging an independent company—CEP Limited in relation to defective works. The board and management called on the contractor to rectify the defects in accordance with the methodology outlined in the CEP report. The HDC said it will not take possession of these townhouses or pay the contractor until these defects are remedied. No payments have been made to Ricky Raghunanan to date,” the HDC’s communications department stated. The amount paid to CEP Limited for its services, however, was not given despite being requested.
How bad was construction work at Trestrail?
Sunday Guardian obtained copies of the independent engineering reports prepared for HDC. The engineering report was submitted on August 30, 2022, by CEP Limited engineers Kern Subar and Hayley Chilton and later reviewed and approved by two senior engineers.
CEP was invited by the HDC to provide a structural engineering solution for structural defects observed on 11 townhouse blocks in zones D and E-1 at HDC’s Trestrail 1-R Housing Development.
“The townhouse blocks that are the subject of this report in zones D and E-1 are incomplete and it was observed that a number of these townhouse blocks in these two zones, which have been constructed with varying finished floor elevations, have experienced cracks at the grade change. These blocks are identified by the HDC as 23, 29, 30, 31, 35, 36, 37, 38, 42, 43 and 45,” the report stated. The report found issues with imposed loads and load combinations, the foundation and the reinforced concrete first-floor slab.
Foundation
Bearing capacity and settlement analyses carried out by CEP suggested that the foundation for some of the townhouse blocks would not be able to support the applied loads, meaning that existing soil conditions would need to be improved to achieve an increased bearing capacity and to reduce the expected settlement of the structure. It was found that the townhouse blocks were unable to support the applied loads of the two-storey buildings.
“The townhouse blocks that will require soil improvement work below the sub-surface (foundation) either wholly or partially across the building’s footprint according to the findings of the geotechnical report are as follows: 30, 31, 35, 36, 37 and 38.
“Based on our discussions with various technical professionals in the construction industry, pressure grouting is considered to be the preferred soil improvement technique to implement for this project,” the report stated.
Reinforced concrete first floor slab
The report found that based on a visual inspection of cored concrete samples of the first-floor slab of Block 35, no reinforcing bars were observed. It also found that the concrete compressive cylinder field strength from a sample of a first-floor slab was one-third of the minimum required strength.
“The concrete sample extracted from the first-floor slab of Unit C of townhouse Block 35 yielded a concrete compressive cylinder field strength of 8.8 N/mm squared which is well below the minimum concrete compressive cylinder strength of 28N/mm square at 28 days specified on the structural drawings,” according to the report.
The report stated that the alternative corrugated galvanised roof sheeting used to support the suspended first-floor slab was not a material recommended for that application as it lacked the material properties for a concrete bond to be achieved and, therefore, no structural design checks could be performed.
“Unlike the composite metal floor decking, the corrugated galvanised roof sheetings are smooth and do not have an embossment pattern manufactured into the sides at regular intervals which will allow the concrete to bond with the metal decking panel as the concrete cures,” CEP’s report stated.
It was recommended by the consultant engineer that a load test be carried out by an independent testing agency so that a determination could be made on whether to demolish and rebuild the first-floor slab or not.
Imposed loads and load combinations
The report found that loads for light fixtures and plumbing services were not considered in the original design, but were included in the structural model and subsequent structural design checks presented in the CEP Limited report. It also found that the wall render load, according to design standards, was not applied in the original design.
Geotechnical Report
A geotechnical investigative report was submitted by EISL Limited on August 10, 2022, after EISL was invited to provide services by CEP Limited. An original geotechnical report for the site was carried out by Trintoplan Consultants Limited in October 2013. Sunday Guardian, however, did not obtain a copy of that report.
According to EISL’s report, the failures observed on-site have been known to be associated with non-conformance to basic construction methods and quality control requirements as it relates to building foundations.
“In the case of cut and fill sites, the oversight of proper compaction procedures and the use of inappropriate fill material has proven to be the reasons for failure … Our desktop study for the site suggests that a considerable amount of cut and/or fill activities were carried out on the site before construction. However, no information on cut and fill levels was obtained from the client. Drawings and topographical surveys which would usually indicate built levels and elevations could not be obtained from the client.
“From the results of our bearing capacity and settlement analysis, it was determined that the foundations of some of the units will be unable to support the applied loads of the two-storey structures,” EISL’s report stated.
The report’s findings warned that insufficient bearing capacity can result in general shear failure–a rupture of underlying soil followed by bulging of soil surface around the footing; local shear failure–a failure pattern observable only immediately below the footing; and/or punching shear failure–a local shear failure that could occur around concentrated loads or column heads.
To avoid these possible outcomes, EISL recommended improvement of the existing soil conditions via grouting (the injection of cement or chemical grout into the soil to fill voids), soil/cement stabilisation or micro-piling to increase the density of the soil.
EISL’s report stated that its engineers investigated damage to many of the building clusters where vertical and diagonal cracks within the front and back walls occurred. It found that the cracks appeared to be related to building dead load conditions.
“1) It was observed that water was ponding near the foundation of townhouse Block 37.
2) There was evidence of uneven settlement of the soil supporting the townhouse structures. The settlement was evident by the presence of vertical cracks, predominantly at the grade changes of the townhouse blocks, stepped cracks and diagonal cracks observed internally and externally
3) The exposed fill layer beneath the driveway slab of townhouse block 37 showed that the fill does not appear to be well-compacted as recommended in the geotechnical report (original), “the report’s field investigations found”.
Raghunanan: We didn't do shoddy work, it's just some little repairs
Contractor Ricky Raghunanan confirmed that he has received no payment to date as it is a finance-and-build project. He said the company has not handed over the project yet, adding that they put up their own money for the work done so far. He said it was not an issue. It is just a matter of him starting back the job to finish it. However, he could not give an estimated completion date for the project.
“It’s not an issue with them. It’s just for us to finish up what we have to do and hand it over. It’s not a story, buddy. It’s something like you buy a car from a bank and when you pay off the bank, you get the vehicle in your name. So once we finish it and hand it over to HDC, then they could do anything.
“You should drive on the project and see it, then talk. It’s just some little repairs. That’s all we have to do. The work was never shoddy or anything like that. We have plenty finished already, but you have to finish everything before you hand it over. It’s about two or three buildings that have to be handed over before we finish everything. When you doing a big project like that, you will have little repairs to do,” Raghunanan said.
Contractor gets jobs from the Works Ministry
Although flagged for structural defects on the Trestrail project, Raghunanan Limited continues to be awarded contracts by the Works Ministry
The award of the first contract came eight months after being asked to remedy the defects.
Meanwhile, the company has since been awarded at least four more contracts by the State worth more than $7.4 million through the Ministry of Works and Transport–Three Highway Division projects in 2023 worth $4.3 million were awarded to Ricky Raghunanan on May 24, September 7 and September 20, and one drainage contract was awarded on September 22, 2023, worth $3.14 million.
The contracts were awarded by limited bidding whereby a list of companies to be invited to submit bids is not determined by prequalification but through market research.
The Sunday Guardian reached out to Works and Transport Minister Rohan Sinanan and the Works and Transport Ministry’s communications department on Thursday and Friday to ask whether there is any communication between ministries or government agencies when a contractor is flagged for substandard work and is under consideration to do work for another ministry.
The Sunday Guardian wanted to find out whether, in light of concerns over the Trestrail Project, the minister is confident about the quality of work that Ricky Raghunanan Company Limited can deliver.
However, the ministry has not yet responded to the Sunday Guardian.
Companies owned by Ricky Raghunanan have received contracts from the Ministry of Works and Transport in the past. Among them, in early 2015, Ricky Raghunanan Scaffolding Contracting Limited received two contracts from NIDCO worth $3.4 million for improvement Works to a retaining wall for Pipiol Road Extension in Cantaro Village and the construction of a 110m reinforced concrete wall at Le Buoys Ravine in Carenage.
In 2017 and 2018, Ricky Raghunanan Company Limited and Kall Co Limited repaired landslides along the Lady Young Road and North Coast roads. Both companies were paid $2.7 million by the Ministry of Works and Transport.
Minister Sinanan said in response to questions raised in the Senate about hiring Raghunanan Limited in July 2018 while overseeing landslide work along the Lady Young, “Our policy now is clear, unless the Attorney General issues a directive that the Ministry is not to deal with contractors, we have to deal with contractors.”
In May 2019, the company received a contract from the MOWT for the hire of mechanical equipment/vehicles ‘as and when required’ for one year.
How the Procurement Act will protect taxpayers
President of the Joint Consultative Council for the Construction Industry (JCC) Fazir Khan said while the JCC cannot comment specifically on the project, the council is not aware that a state-wide policy for addressing contractors’ evaluation and performance ever existed.
“In our opinion, a policy would not have been difficult to develop but implementation across hundreds of government agencies and special purpose companies would have been hard to implement. Not only that, the efficacy of such a system would have been limited without legislation that contains punitive action for transgressors. However, with the operationalisation of the Public Procurement and Disposal of Public Property Act of 2015 (as amended), such a policy is no longer necessary,” Khan said.
He said with the establishment of the procurement depository, all suppliers and contractors are mandated to register electronically and update the necessary information to keep their registration alive. The JCC president said once pre-qualified, contractors can be used by any procuring agencies.
“The new legislation also has mandates for performance review and possible disqualification by any procuring entity based on poor performance or other reasons as prescribed in the act. If this happens, the disqualified contractor cannot be used by any other state agency or procuring entity. Once the system is operated properly under the new legislation, with the independent oversight by the OPR, there is built-in transparency and cross-sector information flow, which will obviate the need for any other policy that relates to contractor performance and across-the-board de-registration,” Khan stated.
